Title: Supersonic wave pump
Inventor: HONDA KEISUKE
IPC: F04F7/00
Filed: 1985-06-29
Abstract: PURPOSE:To send the pressurized liquid by the supersonic waves generated by a vibrating element by constituting the captioned pump from a water inlet passage connected to a water inlet port formed between a pressurizing chamber and a vibrating element, water outlet passage connected to the water outlet hole of the pressurizing chamber and an oscillator connected to the electrode of the vibrating element. CONSTITUTION:Receiving the electric signals having a desired frequency from an oscillator 5, a vibrating element 1 generates supersonic waves. The liquid on a pressurizing chamber 6 side is pressurized by the supersonic waves, and pushed to a water outlet passage hose 8 connected to a water outlet hole 7 at the top edge of the pressurizing chamber 6, and the liquid is supplied successively from a water inlet passage hose 3. Since the water outlet hole 8 at the top edge of the pressurizing chamber 6 is made thin at this time, the internal pressure in the pressurizing chamber 6 increases, but the counterflow of the liquid in the pressurizing chamber 6 side to the water inlet hose 8 side is prevented, since supersonic waves are generated towards the pressurizing chamber 6 from the vibrating element 1. Since the liquid is pressurized by the supersonic waves generated by the vibrating element 1, the mechanically driven parts is removed, and clogging, abrasion, etc. can be suppressed, and maintenance is facilitated.

Title: Wrist watch exclusive to left hand
Inventor: YOSHII HIROYASU
IPC: G04B27/00
Filed: 1994-04-28
Abstract: PURPOSE:To eliminate the discomfort of a left wrist by installing a winding knob on the left side of a dial with twelve o' clock up and six o'clock down. CONSTITUTION:The main functional winding knob of hour, minute, second and date of a wrist watch is installed on the left side of a dial with twelve o'clock up and six o'clock down, and the other kind of winding knob or the like is not fitted at all to the right side. Since present watch bands are mostly made of metal, the watch band is put on loosely to some extent due to a sense of discomfort or oppression at the wearing time. The position of the watch is close to a wrist joint, so that a wrist is sometimes hurt by the winding knob when the wrist is bent to support a body. Accordingly, with the winding knob shifted to the left side, the winding knob does not touch the skin at the time of wearing the watch so as to prevent the skin from being hurt. Due to the improvement of quality in the present watches, the frequency of time setting using the winding knob is reduced to the extent of several times a year. The merit of fitting the winding knob to the right side is therefore lost.

Abstract: PURPOSE:To prevent a TFT pattern from being damaged at the middle of a process by short-circuiting a signal terminal part for inputting to the transistor of a display part with a COM pattern and separating the signal terminal part in the middle of the manufacture process. CONSTITUTION:Concerning the manufacture of the TFT pattern, the signal input part for inputting to a transistor 8 of the display part is short-circuited with a COM pattern independently of peripherally arranged shunt bus lines 2 and 3 just before entering the display part transistor 8. At the middle of the manufacture process, the short-circuited part is separated. Namely, a gate line 10 and an SC line 9 of the TFT pattern are short-circuited by a short-circuit pattern 11. Thus, wiring turned around from an input line 10 toward the display part transistor 8 to a GND 10 is shortened, and wiring resistance can be decreased. Further, process damage can be prevented by forming the short-circuited part 11 of the pattern in the first half of the manufacture process and separating it in the latter half.

Title: Voltage generation circuit for testing ic
Inventor: HASHIMOTO YOSHIHIRO
IPC: G01R1/28
Filed: 1994-06-02
Abstract: PURPOSE:To reduce changes in voltage applied to a load in an operation test by arranging a variable current source to decrease or increase the current the same in amount as that flowing between a connection point at which a voltage is drawn to a feedback circuit and the load opposite to increase or decrease therein. CONSTITUTION:Switches S1 and S5 are turned ON and switches S2, S3 and S4 turned OFF at the measurement of the DC characteristic of a load 1(LSI) to measure the DC characteristic. Then, at the testing of the operation characteristic, the switches S1 and S5 are turned OFF and the switches S2, S3 and S4 are turned ON. As a result, a low resistance R2 comes to be inserted between a connection point O at which a voltage applied to the load 1 is drawn to a feedback circuit 3 and the load 1 and a current I1 is led into a variable current source 4 from the vicinity of the connection point O. A voltage Vy generated across two ends in proportion to a current 12 flowing through the low resistance R2 drives the variable current source 4 through a differential amplifier A5. Thus, the variable current source 4 takes the current 11 thereinto in reverse proportion to the generated voltage Vy of the low resistance R2 from the vicinity of the connection point O.

Title: Clamping circuit of feedback
Inventor: HASHIMOTO SEIJI
IPC: H04N5/18
Filed: 1983-08-06
Abstract: PURPOSE:To obtain the titled circuit having a wide dynamic range and a simple constitution by detecting the level of a part from which a clock noise component is removed. CONSTITUTION:A sample holding circuit 13 as a noise removing means is connected to the succeeding stage of a clamping circuit 14 and a signal amplifier 15. Consequently, the level of a stable dark current component from which a clock noise is removed can be detected by a black level detecting circuit 16. Since the circuit 13 is located in the signal course of the feedback clamping circuit, i.e. a DC circuit, capacity coupling is not generated, so that the dynamic range of the circuit 13 can be utilized at its maximum. Since the circuit 14 is clamped with small capacity, a time constant of coupling between the circuits can be ignored. Consequently, the dynamic range of the circuit system can be extremely improved.
