Title: Jig for printed wiring board exposure
Inventor: ISHIGURE SATORU
IPC: G03F9/00
Filed: 1990-01-25
Abstract: PURPOSE:To eliminate the need for detaching spacers when an exposure mask is fitted or replaced by providing spacer parts where spacers are arranged on a spacer substrate in a punched shape conforming with the outward appearance of a body to be exposed. CONSTITUTION:A spacer A7a and a spacer B7b are arranged and adhered on the spacer substrate 6a in the punched shape 8 conforming with the outward appearance of the body to be exposed. Further, a spacer part 6 is coupled only by exposure mask holding plates 1 and 2 and a hinge part 5. Further, when air is evacuated through a hole B19 so as to improve the adhesion between the exposure mask and the body, airtightness is held by a partition A11 on the spacer substrate 6a and a partition B17 on a lower holding plate 2 to maintain a vacuum state. The upper holding plate 1 and lower holding plate 2 allow the pattern parts of an upper exposure mask 3 and a lower exposure mask 4 to be adhered with both surfaces of the body 18. Consequently, the spacers need not be detached when the exposure masks are fitted, and it is not necessary to place the spacers after the exposure masks are fitted and detach the exposure masks after the spacers are detached for the replacement of the exposure masks.

Title: Power transmission mechanism
Inventor: INUI MASAKI
IPC: F16D43/284
Filed: 1989-01-25
Abstract: PURPOSE:To prevent unstable states such as lowering of torque transmission characteristics by providing, on the inner circumference of the outer rotation member, a circular groove and a plurality of recesses which open at a sliding part with the outer circumference of a working piston. CONSTITUTION:When fine powder is generated in a fluid chamber due to abrasion at relative rotation between a working piston 13 and retainer 15 and a rotor 14, the fine powder invades into the outer circumference 13d of the working piston 13 and the inner circumferential surface of an outer case 11 through a micro gap between a circular outer edge surface 13c of the working piston 13 and a side surface 15b of the retainer 15 because of action of centrifugal force, but after that, it soon moves to the bottom part in a circular groove 11e and accumulates. Therefore, sliding resistance of the working piston 13 is neither increased nor fluctuated by such fine powder, and pressurizing force of the working piston 13 to a frictional clutch 10b is not affected at all. Accordingly, unstable states such as lowering of torque transmission between both shafts 25 and 26 are not generated.

IPC: G04G3/00
Filed: 1979-02-14
Abstract: PURPOSE: To improve the temperature characteristics of an electronic watch by forming a time standard signal using a composite resonator made of the same crystal peices.  
     CONSTITUTION: A resonance circuit and an amplifier are connected to a composite resonator made of the same crystal pieces to form a crystal oscillator 1201 as a time standard signal source. The period of this output is converted to a timing unit signal of a watch by a counting unit signal synthesizer 1202, and the unit signals are counted by a counting mechanism 1203 to thereby form a time information. This information is displayed on a display mechanism 1203. Such a standard signal source can selectively add and synthesize the portions of preferred temperature characteristics of the resonators with excellent temperaure characteristics. Since the steps in a watch is adjusted by a control mechanism provided in the circuit 1202, it does not affect the temperature characteristics. Thus, it can provide an electronic watch having preferable temperature characteristics.

Title: Base-isolated floor structure
Inventor: ARIMA FUMIAKI
IPC: F16F15/023
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To suppress long periodic vibration, and also suppress short periodic artifitial and traffice vibrations by arranging a horizontal vibration attenuation means between a frame hung from a floor stage through a hanging rod and a slab, and supporting a base isolated floor on the frame by means of a vertical vibration attenuation means. SOLUTION: When an earthquake, etc., occurs, horizontal element of the vibration is attanuated by a horizontal vibration attenuation means 60. That is, when a housing dish 64 is moved in respect to a shaft pipe 66, the housing dish 64 is also moved in respect to a disc 71 of a vertical rod 70 through a bearing 74. Vibration energy is eliminated by viscous material 62, and short periodic vibration is insulated. On the other hand, vertical element of the vibration is attenuated by a vertical vibration attenuation means 30. That is, when a lower receiving seat 34 is moved, its motion is not directly transmitted to an upper receiving seat 42 due to a bush bearing 48. Vibration energy is eliminated by the deformation of a compression spring 50 and viscous resistance caused by an attenuation cylinder 46 moving in viscous material 56. Short periodic vibration is thus effectively eliminated.

Filed: 1992-01-31
Abstract: PURPOSE:To obtain a stabilized inside temperature at all times by a method wherein the time of opened condition of a damper for a refrigerating chamber is counted to change a temperature whereat the high-speed rotation of a fan is started. CONSTITUTION:The opening and/or closing of a damper 8 are controlled in accordance with the detecting temperature of a refrigerating chamber temperature detecting means 10 detecting a temperature in a refrigerating chamber 3 and a time during the opened condition of the damper 8 is counted by a timer 26 to change the rotating number of a fan 6 by a rotating number control means 22. When a temperature in a freezing chamber 2 is increased and becomes higher than a set value, the fan 6 is operated with an usual rotation and a compressor 4 is also operated. In this case, a period of time of the timer 26 which counts the opening time of the damper 8 is longer than a predetermined period of time, a temperature whereat the high-speed rotation of the fan 6 is started is lowered slightly to bring the fan into the high-speed operation thereof quickly. Thus, the temperature of a freezing chamber 2 upon a high load can be moved to a range of a set temperature quickly in a short period of time even when a cooler 5 is clogged.

Title: Semiconductor device and design method
Inventor: OKI YUJI
IPC: H01L27/088
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To provide a low power consumption device capable turning on transistors with a time difference and of suppressing a through current by suppressing the through current by means of a switching control circuit so that a P-type transistor and an N-type transistor are not turned on at the some time. SOLUTION: An input from an input terminal 101 for a Pch transistor and input from an input terminal 102 for an Nch transistor are separated. Thus, signals which conventionally are inputted at the same timing are inputted at different timings so that a through current can be suppressed. A time difference is given to output signals for suppressing the trough-current of a circuit connected to the circuit. Namely, a logic is inverted and a difference occurs in signal transmission in an output waveform. Then, the through-current and noises can be reduced without simultaneously turning on the Pch transistor and the Nch transistor of the same type of an inverter circuit, or a buffer-type circuit, which is connected to an inverter circuit, with the difference.
