Title: Setting system for wiring pattern
Inventor: KOBAYASHI TAKESHI
IPC: H05K3/00
Filed: 1989-08-23
Abstract: PURPOSE:To attain automatic wiring and to decrease wiring patterns by setting a wiring track serving as a wiring pattern route between the devices in response to the position of a pin of a prescribed device, i.e., a wiring subject and attaining the automatic wiring by means of the wiring track. CONSTITUTION:A wiring track T serving as the route of a wiring pattern P is set between the prescribed devices D1 and D2 in response to the pin positions of both devices. Then the automatic wiring is carried out by means of the track T when no coincidence is obtained between the pin positions of devices D1 and D2 on an existing wiring track 12. Thus the automatic wiring is attained when the pattern P is set in response to each pin of both devices D1 and D2 regardless of the track 12. At the same time, it is possible to decrease the unprocessed wiring tracks caused by an error produced by a fact that the pattern P is previously set.

IPC: H01L21/203
Filed: 1983-11-18
Abstract: PURPOSE:To keep the epitaxial growth atmosphere clean constantly by providing at least three crystal growth chamber, at least one preparatory chamber and at least one substrate transport chamber and by connecting the crystal growth chamber and the preparatory chamber with the substrate transport chamber through gate valves. CONSTITUTION:Gate valves 6, 7, 8 and 9 are opened only when a substrate, e.g., a semiconductor substrate of GaAs is transferred through the chambers connected by respective gate valves 6, 7, 8 and 9. At epitaxial growth of a multilayer film, the epitaxial growth is performed, e.g., in the crystal growth chamber 3 firstly. At completion of the growth, the substrate is transferred to the crystal growth chamber 3 through the gate valves 7 and 8 and growth of the next film is performed. By this method, e.g., N type impurity and P type impurity are not mixed. And as the air in the crystal growth chambers 3, 4 and 5 and the substrate transport chamber is exhausted to make these chambers a extrahigh vacuum, an epitaxial film is not contaminated by oxygen or carbon and the epitaxial layer of extremely good quality can be grown.

Title: Refrigerant recovery device and tank therefor
Inventor: NAGASHIMA HISAO
IPC: F25B45/00
Filed: 1988-09-01
Abstract: PURPOSE:To avoid excessive filling or refrigerant discharge and hence improve the prevention of public hazards by rotating a cam so as to close both valves simultaneously, taking out a recovery tank where recovered refrigerant is automatically filled in based on a positional release of a refrigerant recovery device, and enabling a recovery device to be removed from a tank easily, and valve handling to be carried out. CONSTITUTION:When a liquid level in a recovery tank 11 reaches a specified position, revaporized refrigerant is filled in an air phase space 15 so that no more liquid refrigerant may not be allowed to enter the tank 11. As a result, the liquid refrigerant is collected on the bottom of a condensation chamber 31; a float switch 41 will be actuated in a liquid level a little higher than that, thereby shutting down a relay 54. Consequently, a relay 52 shuts down a power supply cable way, halts the operation of a compressor and a fan for refrigerating cycle, closes a passage of recycled refrigerant by solenoid valves 59 and 60, and stops the operation of a recovery device in automatic mode, which makes it possible to fill a specified volume of recycled refrigerant into the tank automatically. Then, if an attempt is made to rotate a lever 37 by 1/4, valves 12 and 32 will be closed simultaneously, which makes it possible to lower the tank 11 by a manipulation handle 23.

Title: Audio equipment
Inventor: YOSHIDA HIROYUKI
IPC: H04B15/00
Filed: 1993-08-31
Abstract: PURPOSE:To eliminate noise during search with an inexpensive circuit by using a signal from an audio source set to a high level during search so as to mute an MPX line. CONSTITUTION:Noise might be produced due to an increased current through a motor or a servo circuit when a CD player is set to the search state. The noise enters a ground of a CD circuit 3. The noise enters an MPX line through which a stereo composite signal of a stereo modulation circuit 5 is outputted, but does not enter a ground interconnecting the stereo modulation circuit 5 and an RF modulation circuit 6. Then a signal from the circuit 3 set to be a high level in the search state is used to mute the MPX line through which a signal is received by the circuit 6 from the circuit 5. Thus, noise in the search state does not enter a radio receiver.
