Title: Photodetector
Inventor: SAKATA HAJIME
IPC: G02F2/00
Filed: 1989-03-10
Abstract: PURPOSE:To enable high integration, reduction in loss, and high resolution by forming a diffraction grating in a region wherein each waveguide mode with a waveguide layer and an absorption layer as a center overlap each other. CONSTITUTION:A waveguide layer 101 and a light absorption layer 102 are formed so that waveguide mode whose center is each thereof are different. The diffraction grating 107 is formed in a region whereon each waveguide mode with the waveguide layer 101 and the absorption layer 102 as a center overlap each other. That is, since the diffraction grating 107 is provided between the waveguide layer 101 and the light absorption layer 102 to carry out waveguide mode conversion, waveguide mode of a light having a specific wavelength among lights injected to the waveguide layer 101 transfers to the light absorption layer 102 and is absorbed while propagating. Thereby, only a light strength of a specific wavelength is detected. According to this constitution, it is possible to make a photodetector have wavelength selecting function as well, to realize good wavelength dissolution, and to enable integration.

Title: Low-temperature silo
Inventor: YOSHIDA MASAHIRO
IPC: A01F25/00
Filed: 1991-03-20
Abstract: PURPOSE:To minimize the load on an air-conditioner by opening an air-intake port and a return port for returning and circulating air to the air-conditioner and providing a switching tool to select the return port and the air-intake port. CONSTITUTION:Air conditioned by an air-conditioner 1 is circulated between a storage tank 3 and the air-conditioner through a return line 5. Thermometers 10a, 10b and hygrometers 11a, 11b are placed in the return line 5 and near an air-intake port 6. The data collected by the sensors are transmitted to operators 12a, 12b to calculate the enthalpy of the air. The enthalpy Ha of air in the return line is compared with the enthalpy Hb of outer air by a comparator 13. A controller 14 opens a damper 8a and closes a damper 8b when Ha>Hb and closes the damper 8a and opens the damper 8b when Ha<Hb. The line 5 also has an exhaust port 7 having a check valve 9.

Title: Bucket float type steam trap
Inventor: FUJIWARA KATSUJI
IPC: F16T1/30
Filed: 1979-05-08
Abstract: PURPOSE: To provide a smooth fail-free open/close operation by a mechanism wherein a down-faced bucket float is freely contained in a valve chamber and the float seal-face makes open/close of a valve mouth having a spherical valve seat with an annular groove and installed on the side face of the valve chamber.  
     CONSTITUTION: When a nearly spherical down-faced bucket float 11 having a deaeration hole 12 and a mouthpiece 13 is located at the lowest position, the inner wall of the float ceiling is placed on the top of steam inlet pipe 8 in the valve chamber 5. When steam is passed through pipe 8 and inlet 10 into the valve chamber 5, flotage moves up the float to the two-dot line position. As a result, the surface 15 of the float 11 closes valve mouth 19 having sperical valve seat 22 with annular groove 23 and installed on the side face of the valve chamber 5. When regenerated water enters the float 11, steam condenses and part of which escapes from the hole 12. Thus, the float 11 loses the flotage and opens the valve mouth 19. This protects a valve from conventional engaging or seizure, secures a defined area for regenerated water present between the seal surface 15 and valve seat 22, and thereby provides a constant maximum open valve pressure.

Inventor: HONDA YOSHIAKI
IPC: F04B39/02
Filed: 1984-03-23
Abstract: PURPOSE:To promote the circulation of refrigerant in a communicating tube and improve the cooling effect of a compressor by a method wherein the inlet part of the communicating tube is constituted of a T-shape path to utilize the upper path for refrigerant circulating path and the lower path for lubricating oil returning oil returning path while the inlet port is opposed to the delivery port of compression mechanism with a given inteval. CONSTITUTION:Refrigerant, compressed by a compression mechanism 4, is discharged out of a refrigerant discharging port 6a into the inlet port 9a of the communicating tube 9 and collides against the communicating tube 9 at an intermediate part between the upper path or the refrigerant circulating path 13 and the lower path or the lubricating oil returning path 14 while the lubricating oil, separated together with the refrigerant, is separated here. The separated lubricating oil returns into an enclosed casing from the returning path 14 through an extension path 14a and only the refrigerant circulates through the communicating tube. The refrigerant is cooled gradually by first-third radiators 10-12 and becomes liquid refrigerant near the outlet port 9b of the communicating tube 9, then, returns into the enclosed casing and cools the main body 1 of the rotary compressor.

Title: Disk-shaped recording medium recorder
Inventor: TANJI MASAJI
IPC: G11B21/08
Filed: 1985-03-20
Abstract: PURPOSE:To obtain an excellent disk-shaped recording medium recorder which has high durability with no troublesomeness, by using an unrecorded area detector having a high response speed to check the unrecorded area with high accuracy and at a high speed. CONSTITUTION:When an unrecorded area detector 6 detects a recorded track, a system controller 5 sends a command to a jump pulse generator 9. Thus an optical pickup 3 jumps over tracks and moves forward through an optical pickup driving circuit 10. At the same time, the detector 6 checks whether each track is already recorded or not and detects the recorded tracks. Then the controller 5 stops the jumping movement of the pickup 3 and reads addresses through an address detector 4. The read address information is sent to the controller 5 in the form of the information that shows a recordable area. In this case, it is needed to shift the pickup 3 at a speed with which the detector 6 can perform its detecting action in response to the response speed of the detector 6 even in case just a single truck is recorded.

Title: Semiconductor device
Inventor: TANI KEIZO
IPC: H03F3/343
Filed: 1986-03-17
Abstract: PURPOSE:To shorten the switching characteristic specially switching OFF time toff of a Darlington transistor by so connecting in parallel additional P-N junction diodes between the base layer and the collector layer of one specific transistor that the polarity becomes the same as that of a P-N junction formed by the base layer and the collector layer of the specific transistor. CONSTITUTION:When a transistor TR1 is in ON state (saturated state), a base- collector junction is forward biased due to carrier stored in the vicinity. The forward bias voltage is the forward voltage or lower between the base and an emitter. The forward voltage of an additional diode D1 is the forward voltage or lower between the base and the emitter, and connected in the same polarity as the base-collector junction. thus, it is operated with the forward bias voltage, part of an input base current is branched to the diode D1, and the base current of the transistor TR1 is reduced. Thus, the oversaturated state of the transistor TR1 is prevented, and stored carrier quantity becomes suitable. Since the operation of the diode D1 suppressed the stored carrier in the state that the transistor is ON to a suitable value, a time of erasing the stored carrier can be increased to obtain an effect of reducing toff.
