Title: Light attenuator
Inventor: MITA FUMIO
IPC: G02B27/64
Filed: 1977-09-27
Abstract: PURPOSE: To prevent backward incidence of reflected light to the incident light side and eliminate optical axis deviation of incident light and transmitted light by turning back the transmitted light of the attenuation plate provided with an inclination to the incident light in parallel with the incident light to the incident ligh side and letting the same again transmit through the attenuation plate.  
     CONSTITUTION: The attenuation plate consisting of a glass plate 1 and a metal vapor-deposition film 2 is inclined at an angle θ to incident light P 1 . The optical axis of the incident light P 1  deviates after said light transmits through the glass plate 1, but its optical path is turned back at a rectangular prism 3 and when it enters the glass plate 1 again, the optical axis is again returned to the original incident angle position. At this time, the light passes through the attenuation plate twice and therefore the twofold quantity of attenuation may be obtained

Inventor: TAKADA MASAYUKI
IPC: H03L7/089
Filed: 1993-05-18
Abstract: PURPOSE:To reproduce a clock which is not errorneously locked and has less deviation even if data speed change. CONSTITUTION:A leading signal, an in-phase signal or a lagging signal are outputted from a phase comparator 12 in accordance with the comparison of the phase of an input data edge with the phase of a reproduced clock pulse. The count value of the leading signal in a counter 64 is compared with the count value of the lagging signal in a counter 66 at a comparator 68.

Title: Pressure regulator valve
Inventor: SATOU YUUJI
IPC: F16K17/10
Filed: 1979-09-12
Abstract: PURPOSE: To manufacture a proportional pressure control solenoid valve of good control properties, by providing a pilot circuit pressure regulator valve, which is used as a balance piston type relief valve or the like, with a set spring and a solenoid for seating the valve through the medium of a movable core.  
     CONSTITUTION: A thrusting force is applied to a ball valve 22 by a spring 27 through a push rod 24 and a movable core 25 so that the valve 22 is held on a valve seat 21. When an electrical current is caused to flow through a solenoid 26, the core 25 is attracted to apply a force together with the tensile force of the spring 27 to close the ball valve 22. The opening pressure for the ball valve 22 can be altered by changing the attractive force of the solenoid 26. Since the lift of the movable core 25, namely, an air gap is equal to the lift of the ball valve 22, the air gap is very small. Therefore, sufficient force can be obtained even if the solenoid 26 is small.

Title: Shell-and-tube heat exchanger
Inventor: ONISHI TOSHIYUKI
IPC: F28D7/16
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To improve a heat exchange efficiency by allowing a fluid to be treated to flow fully also to a capillary at the peripheral part out of a bundle of capillaries in a shell-and-tube heat exchanger. SOLUTION: A flow force dispersion body 21 is fixed at a position that is located inside a parallel connection part 18 for connecting a pipe where the fluid to be treated flows and a capillary 8 for exchanging heat of a heat exchanger and faces the connection port of a pipe at the fluid to be treated of the parallel connection part. The flow force dispersion body 21 eliminates a phenomenon where the fluid to be treated is centered only to the capillary 8 at the center out of a bundle of capillaries 8 and allows the fluid to flow fully to the capillaries at a surrounding part, thus achieving heat exchange at all capillaries 8 and improving the entire heat exchange efficiency.

Then, a washing operation is conducted using a heated surface acrtivating agent. The surface activating agent to be used is not limited to acid, alkaline and neutreal ones. The washing operation is conducted while ultrasonic vibration is being given. There is no limit on the ultrasonic frequency, but 28 to 50kHz is considered desirable. Besides, the residue of the surface activating agent on substrate surface can be prevented by hot water washing. By ultrasonic wave washing using a heated surface activating agent after resin etching, the material to be etched remaining on substrate surface can be removed.

Title: Fabrication of semiconductor device and avalanche photodiode
Inventor: ONO KENICHI
IPC: H01L31/107
Filed: 1993-05-19
Abstract: PURPOSE:To obtain a method for fabricating an avalanche photodiode(APD) operating stably by forming the border part between a diffused region and a semiconductor layer for forming the diffused layer smoothly thereby preventing the edge breakdown effectively. CONSTITUTION:An implantation cap layer 6 is formed on an n-cap layer 5. A mask layer 8 of Si3N4 is formed thereon and etched selectively to form a predetermined ring pattern which is then used for ion implantation of Be (beryllium), for example, through the implantation cap layer 6 over the n-cap layer 5 thus forming a guard ring region 14. The implantation cap layer 6 and the mask layer 8 are eventually removed. Consequently, the gurad ring region is formed smoothly and the field concentration at the junction of the guard ring region and an underlying semiconductor region is relaxed. As a result, breakdown is restrained at the junction thus enhancing the stability and controllability of APD.
