Title: Double frequency multiplier circuit
Inventor: TSUKAHARA MASAHIRO
IPC: H03B19/16
Filed: 1994-03-29
Abstract: PURPOSE:To use a full wave rectifier for a double frequency multiplier circuit with an excellent high frequency characteristic by allowing a waveform shaping circuit to provide an output of an output signal whose frequency is twice the frequency of an input signal when the input signal is given to the full wave rectifier comprising diodes. CONSTITUTION:Suppose that e.g. a 800MHz sine wave is applied between input terminals T3 and T4 as a carrier CW, the terminals T3, T4 are connected to a full wave rectifier 5 comprising diodes D1-D4 and an output signal therefrom is given to a waveform shaping circuit 6. The circuit 6 is made up of an ECL circuit comprising NPN TRs 1, 2 and output TRs TR3, TR4. In the double frequency multiplier circuit formed as above, upon the receipt of the carrier CW, the rectifier 5 outputs an output signal SG obtained by applying full wave rectification to the carrier CW and given to a base of the TR 1 to set a reference power supply NBB to a prescribed level and the TRs 3, 4 are alternately turned on/off by turning alternately on/off the TRs 1, 2 to provide an output of the carrier CW1 whose frequency is twice that of the carrier CW.

Title: Compacting pile for high proof stress cast-in-place concrete pile, etc.
Inventor: FUKUHARA TAKUHEI
IPC: E02D5/34
Filed: 1993-03-19
Abstract: PURPOSE:To prevent the solidification of cement milk by providing an adiabatic layer on the periphery of a cement milk filling pipe arranged in a hollow part inside a pile, and preventing the transmission of frictional heat occurring during rotatingly pressing a pile into a top ground to the filling pipe. CONSTITUTION:In the case where a compacting pile 3 rotatingly advances through a top ground, frictional heat occurring between the pile 3 and the top ground is surely interrupted by an adiabatic layer 9 formed of air and foamed mortar or the like. Since the heat is not transmitted to cement milk 8 in a filling pipe 6, there is not possibility that the milk 8 solidifys to cause the colgging of the pipe, and the milk is surely and effectively jetted from a jetting hole 7 to be injected in the top ground. A core sand mold used in casting the pile 3 is preserved, and such kind of sand layer may be used for the adiabatic layer 9. Thus the tip supporting force of the pile or the like can be enlarged, and the compacting effect for the top ground can be sharply improved, and moreover the executing ability, quality and reliability of a proof stress cast-in-place concrete pile can be improved.

Title: Strain sensor
Inventor: YOSHINO TOSHIHIKO
IPC: G01D5/26
Filed: 1984-03-28
Abstract: PURPOSE:To improve sensitivity without especially increasing the length of a fiber detecting part, by providing a reflecting surface at the end part of the optical fiber detecting part, which receives the action of an external force, and passing laser light through the detecting part twice. CONSTITUTION:Laser light from a laser light source 1 is inputted from an end part 5a to an optical fiber 5. The laser light is transmitted through a pair of cores 8A and 8B, reflected by an other end 5d and emitted by the end surface 5a again. Then the light is reflected by a beam splitter 3, and interference fringes G are formed on a two-dimensional image sensor 11. In correspondence with the amount of strain of the optical fiber detecting part 5c, difference in lengths of the light paths of the cores 8A and 8B is yielded. The laser light passing the cores 8A and 8B receives the effect of strain twice in the outgoing path and in the returning path. Therefore the change in interference-fringe pattern becomes about twice in comparison with the change in interference fringe pattern of the laser light emitted from a free end 5d without providing a reflecting surface 7 at the free end 5d of the detecting part 5c. Thus high sensitivity can be obtained without increasing the length of the detecting part 5c.

Filed: 1992-03-17
Abstract: PURPOSE:To provide an outer label for alkaline battery which can make it possible to electrically detect as an insulation defective product by solving such a problem that any defective product where electrolyte leaks from a unit cell is unable to be detected in a foil coated alkaline battery. CONSTITUTION:Lamination, as an external label, of an insulative thermally shrinkable synthetic resin film 3 and a printed layer 2 are partly omitted to cause an aluminium deposition layer 4 to be partly exposed. When alkaline electrolyte is leaked out from a unit cell, an adhesive agent layer 5 and the aluminum deposition layer 4 are dissolved with the result that a metallic container is exposed. By applying a high voltage across a positive pole terminal and this exposed metal portion, the battery can be detected as an insulation defective product.

Abstract: PURPOSE:To lighten a device by detecting the direction of a Moire fringe generated by first and second lattices, detecting the dislocation of a focusing position dislocation and correcting the focusing position dislocation. CONSTITUTION:A light made into a parallel light flux once from a semiconductor laser 1 through a collimator lens 3 is converged by an image forming lens 6, radiated in a dot way to the image forming surface of an optical disk 7, and when a reflecting light is converged and returned by an image forming lens 7 again, comes to be a divergent light or a converging light flux. This is made incident on lattices 8 and 9 to generate Moire fringes and by detecting the direction of the Moire fringes, the focusing of the image forming lens 7 is executed. Thus, only two lattices of the simple constitution may be used, the whole of the focusing device can be lightened and the mass production is improved and a cheap device can be obtained.

Title: Bulb socket
Inventor: SAWADA TAKASHI
IPC: H01R33/09
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To stabilize a force for holding a bulb and a force required for inserting/extracting the bulb if variations are developed in the plate thickness of a base part. SOLUTION: A base part 3 uses glass as its material and therefore the dimensional tolerance of its plate thickness is set at a relatively large value, As the plate thickness of the base part 3 increases, the distance between a side surface of the base part 3 and a flexible receiving piece 40 is shortened and the amount of deflection of an elastic deflection piece 30 is increased. However, a pressing position 50 of the elastic deflection piece 30 relative to the flexible receiving piece 40 is displaced toward a free end 42 of the flexible receiving piece 40, and therefore the flexible receiving piece 40 easily escapes to the outside.  In comparison with a case where the deflection rigidity of the flexible receiving piece 40 is constant, the increase in the amount of deflection of the elastic deflection piece 30 is suppressed relative to the increase in the plate thickness of the base part 3.

Title: Pressure attachment device
Inventor: HIRANO KOJI
IPC: H01R43/042
Filed: 1994-03-04
Abstract: PURPOSE:To provide a pressure attachment device with which the relative positioning between the front extremity of a terminal and the tip of a detent piece does not vary even though the core attaching part of the terminal goes in elongation in conducting the pressure attachment. CONSTITUTION:On a crimper 12 of a pressure attachment device, a detent contacting part 34 is furnished in a position near the insulation crimper part 30. In conducting pressure attachment, a core attaching piece 44 of a terminal 40 elongates, and its tail 48b moves backward (as arrow B). A detent 48 on the terminal 40 contacts the corner 34a of the detent contacting part 34, and the front corner 48a of the detent shifts forward (as arrow (A) so that the elongation of the core attaching piece 44 is compensated. Therefore, the length between the front extremity of the terminal 40 and the front corner 48a remains unchanged.

Filed: 1990-03-12
Abstract: PURPOSE:To improve the transaction processing efficiency by reserving a requirement and the prescribed record showing an allocated page as a transaction log in the case of requiring an allocated page to be an idle state and setting the state display that is decided by the end state of a transaction and its log. CONSTITUTION:A data control part 22 receives a processing requirement from a transaction 26 and refers to an area control table to select a page in the case of requiring the page in an idle state to be allocated. When a requirement is received for the security of an idle state of the allocated page, the page designated by the requirement is selected. Then the state display corresponding to the page selected via the area control table is defined as a second state display. Thus the requirement and the prescribed record showing the selected page are reserved as a log of the transaction 26. When the transaction 26 is ended, the state display decided by the end state and its log of the transaction 26 is set as the state display corresponding to the relevant page of the area control table. Thus the transaction processing efficiency is improved.

Abstract: PURPOSE:To decrease the quantity of the work of the reconnection of a public line and man-hour by allowing a detection means detecting the deterioration of a high speed digital line to retard a signal to a network control unit when the deterioration of the high speed digital line is detected. CONSTITUTION:If an open line takes place in a high speed digital line 9, a line deterioration supervisory section 11 decide the presence of the interruption of the received signal and informs the result to a control section 12 to send the reception signal to an NCU interface section 13 as it is. The control section 12, only when the result of line deterioration is inputted, outputs a hold signal to the NCU interface section 13 to retard the off-state of control signals CI and DR, and even when the signal from the line deterioration supervisory section 11 is not given, the NCU interface section 13 does not interrupt the control signals CI, DR. After a prescribed time elapses, control signals CI, DR and ER are interrupted. Thus, the channel between the host and a terminal equipment is ensured and the man-hour and quantity of reconnection from a public line are reduced.

Title: Controller for synchronous ac motor
Inventor: NAGAE NORIYUKI
IPC: H02P1/46
Filed: 1986-03-20
Abstract: PURPOSE:To rotate a motor smoothly from the beginning, by loading the output signal of an encoder to an up and down counter when a power source is turned ON, and flowing a sine wave when the power source is turned ON. CONSTITUTION:When a power source is turned ON, the output of a decoder 7 is loaded to an up and down counter 4 on a reset signal (a), which is outputted through an OR circuit 8. Thereafter, the up and down counter 4 immediately performs addition and subtraction operations of the up and down pulses, which are obtained in a pulse processing circuit 2 from the signal of an increment type encoder (c). Thus the phase output (d) having high resolution is outputted. Therefore, a sine wave current flows at the time when the power source is turned ON. When the first edge of the pulse from an absolute type encoder (b) is detected by an edge detecting circuit 1, the phase of the decoder becomes 0 deg. or about 359 deg. depending on whether the motor is rotated in the forward direction or in the reverse direction. Then the accurate phase output is obtained.
