IPC: B23K9/073
Filed: 1984-04-20
Abstract: PURPOSE:To generate substantially no spatters in a wide welding condition range from low to large current by superposing respectively optimum pulse currents in the stage of a short circuit and in the stage of an arc on the base current substantially smaller than said currents by detection signals for the short circuit and the arc so that the short circuit is forcibly executed. CONSTITUTION:The voltage transformed 3 to a prescribed voltage and rectified 4 to DC is outputted and is passed to an electrode 7c to generate an arc 7d between the electrode 7c and a base metal 7a. The electrode 7c is fed at a constant speed by feed rollers 7a for driving 8 said electrode. The voltage value set in a reference signal generating circuit 11 and the value detected by an arc voltage detecting circuit 9 are compared in a discriminating circuit 10 by which the short circuit is discriminated. The signal from the circuit 13 is thereafter stopped at the same instant when the signal of the arc state from the circuit 10 is applied. The pulse current for the short circuit is passed in the instantaneous short-circuit state at the tip of the electrode to prevent generation of spatters.

Title: Field-effect transistor
Inventor: KUDO ATSUSHI
IPC: H01L29/778
Filed: 1988-03-30
Abstract: PURPOSE:To obtain a field-effect transistor as a high-performance device having a wide range of application by providing the transistor with a multichannel constitution using a potential well as a channel for electron transit. CONSTITUTION:A field-effect transistor is composed of a semi-insulating InP substrate 1, an InP epitaxial layer 2, a semiconductor layer 3 in which In1-xGaxAs (x=0.47) 9, 11, 13 and InP 10, 12, 14 in lattice matching are laminated alternately, a gate insulating layer 4, a gate electrode 5, and source-drain electrodes 6, 7. Gate voltage is controlled, and the transistor is used as an ON state and an OFF state, thus operating the transistor as a normal ion type field-effect transistor FET. Since the MISFET has high breakdown strength, high voltage can be applied to a gate, ON-OFF operation can be conducted sufficiently even at the time of a number of channels, and the MISFET can be worked easily even in a large number of channels of five or ten. Accordingly, current driving capacity is increased, and application to a high-speed logic element, a large output element, etc., is especially broadened, thereby acquiring a high-performance device having high reliability.

Title: Clutch disc
Inventor: KUDOU RIYOUICHI
IPC: F16F15/123
Filed: 1982-05-13
Abstract: PURPOSE:To stabilize the operation of a clutch disc by applying a vertical pressing force to the end surface of a buffer spring between the inside and outside hub flanges to stabilize the operation of the buffer spring. CONSTITUTION:By fixed plates 32 mounted on both sides of an inside hub flange 14a, the opposed end surfaces of the inside hub flange 14a and an outside hub flange 14b are adapted to receive and press the end of the first buffer spring SP1 at their entire surfaces orthogonally to a shaft of the first buffer spring SP1, so that force acts upon the end surface of the first buffer spring SP1 equally, and there is no force for axially projecting the first buffer spring SP1. Since the force works upon the end surface of the buffer spring SP1 vertically, a fixed buffer action is available, and basides even if an angle of torsion for uniting the inside hub flange 14a and the outside hub flange 14b into one body is large, the buffer spring is stable, and a spring constant of the buffer spring SP can be reduced.

Abstract: PURPOSE:To resynthesize a tomographic image to which an out-of-focus image is not applied by constituting the method so that an image of an arbitrary cross section which is taken notice of can be resynthesized completely without being influenced by an image of other tomography. CONSTITUTION:An X-ray generator 2 moves on a first track, and executes X-ray irradiation plural times. An X-ray detector 3 moves on a second track, and records plural pieces of X-ray projection images of an examinee 1 by synchronizing with irradiation of X rays. Each X-ray projection image is converted to data of a space frequency area of data for showing a linear absorption coefficient of the examinee 1, and with respect to these data, simultaneous equations shown by the product of a transfer function of the space frequency area related to a deviation of a projection image determined in advance at every depth 11...1M of an X-ray irradiated position, an X-ray projection image recording position and the tomographic surface of the examinee 1, and an X-ray absorption coefficient distribution of an unknown space frequency area of each tomographic surface are solved. The X-ray absorption coefficient distributions of the space frequency areas of each tomographic surface are derived and these X-ray absorption coefficient distributions are converted to data of the X-ray absorption coefficient distribution of a real space area. In such a manner, the tomographic image being free from an out-of-focus image is obtained.

Abstract: PURPOSE:To speedily and accurately count the number of corpuscles, by a method wherein  corpuscles are discriminated by comparing the detection voltage signal generated by a picture  sensor according to the quantity of light received by each picture element for a magnified picture,  corresponding to the transmitted light quantity, with reference voltages, and counted by means of  a counter. CONSTITUTION:A diluted specimen 3 including corpuscles such as red corpuscles is irradiated  with a beam of light from a light source, and a magnified transmitted-light picture is received by  a picture sensor 7 such as a line sensor through lenses 4 and 5, a pinhole 6 and the like. Then, the  sensor 7 generates a detection voltage corresponding to the quantity of light received by each picture element. At the same time, said voltage is applied to a decision circuit 10 provided with a  calculating circuit through a driving circuit 9 which applies starting signals to a various clock  pulse generating circuit. Thereupon, the circuit 10 compares the applied voltage with reference  voltages within a given range and outputs a signal 1 only when the applied voltage is within the  given range and it is decided that the picture element is one which has received the light having  passed through a corpuscle and having a quantity within a given range, so that a counter operated at a necessary timing is advanced. By said constitution, the number of corpuscles can be counted  speedily and accurately.

Title: Method for detecting degradated conditions in sealed lead battery
Inventor: KUDO AKIHIKO
IPC: H01M10/48
Filed: 1988-03-31
Abstract: PURPOSE:To accurately perform detection by measuring the inner resistance of a sealed lead battery with the frequency over 100Hz and below 100Hz while charge current is supplied. CONSTITUTION:When degradation occurs due to the elongation of lattice, the inner resistor measured with the frequency 10Hz while a charge current is supplied increases with the lowering of capacity, and it is detected that there is the progress of the degradation due to the elongation. The change in the inner resistance when the degradation progresses to 50% of the rated capacity is about three times and greater about two times in comparison with that when charge current is not supplied, and more accurate detection can be done. When an electrolyte decreases, it can be detected that the degradation in capacity and the rate of degradation due to the increase in the inner resistor by performing measurement at the frequency 1kHz, and when the degrading comes to 50% of the rated capacity, the change in the inner resistance becomes about four times as the initial value. It is thus possible to perform accurate detection and measurement while trickle charging is performed since the measurement is carried out by supplying the charge current.

IPC: H02M7/155
Filed: 1979-06-27
Abstract: PURPOSE:To reduce the instantaneous current irregularity by a method wherein when an ignition angle of controlled rectifier lags and no ignition pulse is obtained for a specified time, interrupting pulses are given alternately to controlled rectifier units which have small instantaneous value of output voltages. CONSTITUTION:In each ignition pulse generating circuit 12-1 and 12-2, outputs from each synchronizing signal detecting circuit 8-1, 8-2 are counted to represent a phase angle and the counted result is reset by output signals 58, 59 of comparators 10-1, 10-2. When an ignition angle controlling signal 57 varies and the ignition angle lags, the space between ignition pulses of output signals 58, 59 increases and exceeds the preset value, and then overflow of counts in the ignition pulse generating circuits 12-1, 12-2 takes place, and an ignition pulse is generated. Output signals of inhibit devices 13-1, 13-2 are processed to get a logical sum by the output signals 58, 59 of the comparators and OR devices 15-1, 15-2 and thereby ignition pulse train signals 64, 65 are obtained.

IPC: B41J5/30
Filed: 1986-04-09
Abstract: PURPOSE:To enhance the processing capacity of a printer, by a method wherein three printing buffers are appropriately changed over by a printing buffer change-over means to allow one of the other printing buffers to receive the next printing data while the printing data temporarily accumulated in one of said printing buffers are printed. CONSTITUTION:A control part 13 performing the control of the whole of a printer performs the change-over of printing buffers 10, 11, 12 through a printing buffer change-over part 14 and controls the transmission of data between said buffers. When printing is applied to two different areas A, B, the printing buffers 10, 11, 12 are subjected to processing in the order of states 1, 2, 3, 4, 5, 6, 7. Because printing is started at the point of time when the printing start conditions of a single printing area become ready, only three printing buffers are needed.

Title: Image pickup tube
Inventor: MARUYAMA MASANORI
IPC: H01J29/48
Filed: 1982-05-14
Abstract: PURPOSE:To obtain an image pickup tube having a collimation lens sytem with graphic distortion characteristics in simple structure by applying higher voltage than the second cylindrical electrode to the first cylindrical electrode and higher voltage than the first cylindrical electrode to a mesh-type electrode and forming a double collimation lens. CONSTITUTION:A cylindrical electrode that comprises a collimation lens system consists of two cylindrical electrodes 32 and 33 that are adjacent to a mesh-type electrode 2 and are arranged in parallel in the axial direction. One near the mesh-type electrode 2 is the first cylindrical electrode 32 and the other far from it is the second cylindrical electrode 33. Double lens structure to which different types of voltage are applied separately is used for these first and second electrodes 32 and 33. The angle of incidence of an electron beam 4 onto the mesh- type electrode 2 can be made to approach to more reduced vertical incidence by equivalently expanding the region of the collimation lens like this. As a result, the landing angle and shift into a target 1 can be reduced.

Title: Ventilating device for heat exchanger
Inventor: KAIHARA MAKOTO
IPC: F25B39/02
Filed: 1984-04-20
Abstract: PURPOSE:To uniform the velocities of air passing through the heat exchanger and improve heat exchanging capacity by making intervals between fins of the heat exchanger short at the proximity of a cross-flow fan and long at a part remote from the fan. CONSTITUTION:The heat exchanger 1 is formed so that the fins, having lengths equal to the length from the lower end to the upper end of the exchanger and the lengths equal to the length from the lower end to the middle part of the exchanger, are arrayed alternately and the distances between fins at the lower part of the heat exchanger 1 become half of the same at the upper part of the heat exchanger 1. By providing the heat exchanger 1 with such configuration, the distances between fins at the lower part of the heat exchanger 1 become small and the same at the upper part of the heat exchanger 1, which part is remote from the cross-flow fan 2, become large, therefore, air velocity distribution becomes substantially uniform in the whole of the device compared with the case of prior art shown by broken lines and the improvement of a total per- formance may be contrived.

Filed: 1986-04-07
Abstract: PURPOSE:To enhance the throughput of printing, in performing printing by one printing operation at the time of emphasis-printing, by lowering a printing speed to one half of a usual printing speed without dividing printing operation into two times. CONSTITUTION:For example, when response frequency is 1kHz, a printing control part rotates a spacing motor at 1,000pps at the time of a usual character and drives a printing head at every 1ms to perform printing. At the time of emphasis-printing, the printing control part rotates the spacing motor at 500pps being a half speed and controls the impact timing of the printing head at every 1ms to perform printing. That is, the emphasis-printing is performed by rotating the spacing motor at 500pps being one half of the usual speed and controlling the printing timing at every 1ms to print the sme printing data at every two dots in a lateral feed direction 1.
