Filed: 1993-02-18
Abstract: PURPOSE:To actuate the specific power amplifier module selectively by impressing a signal, which is a matrix making the product that is a unit matrix with a matrix describing an input/output relation of a matrix circuit and decides an amplitude and a phase, to the matrix circuit as a test signal. CONSTITUTION:The predetermined amplitude and phase are set in a variable gain/phase device 15 of a test signal generating circuit 12, and the test signal expressed by a formula I=M<-1>O or a formula I=AO (I represents input signal serving as a test signal, M<-1> represents inverse matrix of a complex matrix M of (n) rows and (m) columns, A represents a matrix of (m) rows and (n) columns, 0 represents an output signal). When this test signal is inputted into a matrix circuit 31 via a switch 11, the test signal is given to only the corresponding power amplifier module 32. A power comparator 16 compares a signal power from a signal source 13 in the circuit 12 with a signal power of an output terminal 34 of the selected module 32 and determines an input/output characteristic of the module from the comparison result, and adjustment of a gain or a phase is carried out according to the input/output characteristic of the module.

IPC: B41J31/00
Filed: 1986-02-13
Abstract: PURPOSE:To make required transfer recording density and image quality constant, by using a thermal transfer sheet having ink transfer auxiliary particles mixed therein and mounting a heating means for heating only the vicinity of the surface of a recording medium prior to performing transfer recording. CONSTITUTION:The heat generation of a heat generator 520 is controlled by the electric signal applied to the heat generator 520 and the ink material 121 on a transfer sheet 100 is melted and transferred to the surface of a recording medium 200 to form an image. Herein, a blank part not coated with a thermal transfer layer 120 is provided before the thermal transfer layer 120 of three colors and contacted with the recording medium 200 under pressure by a thermal head 510 to apply heat to said recording medium and only heat treatment is applied to the surface of the recording medium. Therefore, in performing lap- recording, the surface state of the recording medium at the time of the transfer recording of a second color ink can be made approximate to that of the recording medium at the time of the transfer recording of a first color ink and, because the amount of each color ink to be transferred becomes stable, color gradation recording imparting high image quality can be performed.

Filed: 1982-02-25
Abstract: PURPOSE:To purify water in the tank by furnishing a control device, which is actuated by a sensor for the condition of water, having thereby proper adjustment of the water, and by replacing water in the receiver tank automatically. CONSTITUTION:When the water level attains the upper limit point (water increases when the water contained in the inhaled atmosphere liquefies), an electric signal is given from a level sensor 12, which is to sense the water level in a receiver tank 7, to actuate a control device 13. Thus a solenoid valve 14 is opened to exhaust the water 15 from the receiver tank 7 as well as a water supply device 4 is released to supply new water to a compressor 1. When exhaust  of the water 15 depress the water level in receiver tank 7 to the lower limit  point, the solenoid valve 14 is shut and the water supply device 4 also. Thus the  15 water in the receiver tank 7 can be purified through automatic replacement.

Title: Double-sided suction pump
Inventor: SUDOU SUMIO
IPC: F04D1/06
Filed: 1978-03-17
Abstract: PURPOSE: To make time interval differ in which each blade passes by an exhaust volute inlet so as to reduce vibration and noise due to resonance and the like, by arranging different number of blades with equal pitch in the left and right flow paths of impeller.  
     CONSTITUTION: Central wheel plate 6 of an impeller 1 is extended to the outer periphery thereof. Different number of blades, the right ones 1aW1d and the left ones 1a'W1d', are arranged with equal pitch respectively in the flow paths 1A, 1B of impeller divided into the left and right. Since the blades arranged in the respective flow paths 1a, 1b with equal pitch differ from each other in the number, apparent pitch becomes unequal(P 1 ≠P 2 ) at an exhaust volute inlet 5. Thus heavy pressure pulse of particular frequency(number of blades x rotational frequency) can be prevented so that vibration and noise of pump and exhaust piping system can be reduced.

Title: Exposure information display circuit in camera
Inventor: ANAKURA HIROHISA
IPC: G03B7/01
Filed: 1979-03-16
Abstract: PURPOSE: To make possible the instantaneous observation of the difference in both exposure information by displaying the both of the 1st and 2nd exposure information, such as manual shutter time and operated shutter time, identifiably.  
     CONSTITUTION: In the display circuit, a LED driver circuit 63 consists of 16 LED drivers and when the selected one driver goes ON, only one point LED is driven to emit light. The point LED corresponding to the operated shutter time is driven to emit light when the 1st clock pulse signal ϕ 1  is L irrespective of the 2nd clock pulse signal ϕ 2  and the point LED appears to be lighting statically. On the other hand, the point LED corresponding to the manual shutter time is driven to emit light only when the 2nd clock pulse signal ϕ 2  is L and the 1st clock pulse signal ϕ 1  is H and the point LED appears to be flashing. In this way, the both shutter times are displayed simultaneously, the former by flashing and the latter by normal lighting and therefore the difference of the both exposure information may be instantaneously observed.

Title: Automatic wire feeder for arc welding
Inventor: FUJIWARA KIROKU
IPC: B23K9/12
Filed: 1984-02-22
Abstract: PURPOSE:To improve stability of a welding arc by maintaining the specified extruding torque of the welding wire itself on a motor side with a speed reducer in an arc welding device and feeding the welding wire at a specified speed. CONSTITUTION:When armature current increases as a result of a fluctuation in a welding load in the stage of arc welding, the voltage drop Er increases in proportion to said increase and therefore a control input Ei decreases. The phase of the gate signal delivered from a phase control circuit 21 delays consequently and the conduction angle of a control element 30 decreases, thus controlling the increase in the armature current. When the armature current decreases, the output torque is returned to the set value by the operating process reverse from the above. When an armature voltage Em increases and the voltage drop Er corresponding to said voltage increases with an increase in the number of revolution of a push motor 29, the Er is fed back to the element 30, by which the torque of the motor 29 is increased. The feed torque on the push side roller is maintained roughly at the specified value below the rated number of revolution.

Title: Manufacture of semiconductor device
Inventor: KOBAYASHI IZUMI
IPC: H01L21/265
Filed: 1990-02-09
Abstract: PURPOSE:To prevent the deterioration of conductance due to hot carriers by constituting a semiconductor device so that a gate electrode made of polysilicon and molybdenum silicide may overlap an n<-> diffused layer. CONSTITUTION:A P-type silicon wafer 101 is spread with an oxide film 102, a polysilicon film 103 by CVD, and a molybdenum film 104 by sputter. After patterns are formed out of a positive resist layer, a gate electrode is formed by anisotropic etching. The next step of overlaying this electrode with a titanium film 105 and of lamp annealing grows a titanium silicide 106 on the side wall of the gate electrode's polysilicon film. Then wet etching of the titanium film forms a spacer 106 of titanium silicide, and ion implantation of phosphorus develops an n<+> diffused layer 108. Setting the range of phosphorus slightly thicker than the titanium silicide film formed that time creates an n<-> diffused layer 107. This process can increase drain current and avoid the deterioration of conductance due to hot carriers.
