Title: Apparatus for liquid phase epitaxial growth
Inventor: MAEDA AKIO
IPC: H01S5/00
Filed: 1985-03-29
Abstract: PURPOSE:To prevent the remnant of a semiconductor solution of the opposite conductive type adhering to a semiconductor plate material at the bottom from mixing up by a method wherein a vacant bath is provided between an N-type semiconductor solution bath and a P-type semiconductor solution bath. CONSTITUTION:A carbon slider 10 is provided at the lead of a group of semiconductor solution baths. A semiconductor solution bath 6a is filled with N-GaAlAs solution 21 and a solution bath 6b is vacant and solution baths 6c, 6d and 6e are filled with P-GaAlAs solution 22, 23 and 24. With this arrangement, when, for instance, the N-type semiconductor solution bath 6a is on a polycrystalline GaAs board 4a, the N-type semiconductor solution may adhere to the surface of the board 4a, but, as the vacant bath 6b comes onto the board 4a when the group of the semiconductor solution baths is shifted, there is enough time to form the N-type semiconductor. Therefore, the N-type semiconductor solution adhering on the board 4a is not mixed up with the P-type semiconductor solution.

IPC: F25B13/00
Filed: 1994-04-06
Abstract: PURPOSE:To raise a heat exchanging efficiency as compared with that of parallel flows and to improve an efficiency by sealing non-azeotrope refrigerant in which at least two or more types of non-azeotrope refrigerants are mixed, and setting a refrigerant flowing direction of a heat exchanger as counterflows to an air flowing direction at the time of both heating and cooling. CONSTITUTION:The air conditioner comprises valves 2a-2d as first refrigerant channel switching units, and valves 4a-4d as second refrigerant channel switching units. At the time of heating, the valves 2a, 2c, 4a, 4c are set to open states in the first and second units, and the valves 2b, 2d, 4b, 4d are set to closed states. In the case of cooling, the valves 2b, 2d, 4b, 4d of the first and second units are set to open states, and the valves 2a, 2c, 4a, 4c are set to closed states. Thus, refrigerants flowing in an outdoor heat exchanger 7 and an indoor heat exchanger 3 become counterflow to the air flow at the time of both heating and cooling, and hence a temperature difference from the air flowing at its periphery is held.

Title: Method and apparatus for detecting remaining amount of carbon dioxide gas for welding
Inventor: KIMURA KEN
IPC: B23K9/16
Filed: 1984-04-09
Abstract: PURPOSE:To secure a specified amount or more of carbon dioxide gas all the time and to eliminate inconvenience in working, by measuring the weight of a gas bomb, and detecting the fact that the amount of the carbon dioxide gas in the gas bomb gets lower than the preset remaining amount. CONSTITUTION:The rewinding force of a constant-output spring and the weight of a poise are set at a force, which is in balance with the total weight of the weight of a vacant bomb including a gas-flow-rate adjuster, weight of a mounting table 2 and the preset remaining amount of the gas. When the unused bomb is mounted on the mounting table 2, the mounting table 2 overcomes a mounting- table pushing-up force and is lowered. A lever 8 becomes the state shown by a dotted line in the Figure. A limit switch 17 is actuated. With the consumption of the gas, the weight of the bomb is decreased. When the sum of the weight of the remaining gas and the weight of the bomb becomes smaller than the mounting- table pushing-up force, the mounting table 2 is pushed up and the limit switch is released. As a result, the carbon dioxide gas of a specified amount or more is always secured, and the hindrance of working is avoided.

Filed: 1991-01-10
Abstract: PURPOSE:To enable not only a piano tuner but any person to make accurate tuning work by measuring the operation amount of a hammer by means of a measuring rod placed on the top end of the hammer. CONSTITUTION:A measuring rod 1 is inserted between a string S on a hammer H to be measured and an adjacent string S'. A carrier table 4 is placed on the strings S and S'. Depressing a measuring tube 2 to rotate an engagingly locking rod 3 on the bottom end of the tube. The strings S and S' are sandwiched between the locking rod 3 and the carrier table 4 by means of the spring force of a spring S. Since the top end of the measuring tube 2 serving as a measuring reference is determined on the basis of the undersurface of the string S, measurement is not affected by the difference in the string diameters between low and high tone zones. The measuring rod 1 is then rotated and either the vertical or horizontal portion is placed on the top end of the hammer H to finish the measurement. Since the measuring rod 1 is made of a thin wire material, hammer action is not affected even if it is placed on the hammer on the way of operation.

IPC: G01D5/36
Filed: 1986-03-28
Abstract: PURPOSE:To realize a method for forming exactly a signal even if a variance exists in the outside diameter dimension of a drum, by executing an intermittent exposure to the drum. CONSTITUTION:As for a drum 1, a magnetic film layer is coated to the outside peripheral surface, and also, on said layer, a photoresist layer is coated. This drum 1 is set to a revolving shaft which is driven intermittently by a motor 4. Subsequently, the motor 4 is rotated, its rotation is detected by an encoder 5, and its information is inputted to a control circuit 8. Next, the circuit 8 outputs a light emitting command to a light emitting power source 9, whenever the drum 1 rotates by a necessary signal pitch portion of the drum 1. In this way, when the power source 9 operates, a light source 6 emits light beams instantaneously, and the photoresist layer is exposed by an exposure pattern which has been provided on a mask 7. Accordingly, especially, the exposure is executed at every rotation of a prescribed angle against the shaft, and even if a variance exists in the outside diameter of the drum 1, a necessary number of signals can be recorded with a high accuracy. Also, as for a change of the outside diameter of the drum 1 and a change of the number of signals, it is possible to cope with it by changing a little the encoder 5 and the circuit 8.
