Title: Liquid phase epitaxial growing device
Inventor: OKUDA SHINYA
IPC: H01L21/208
Filed: 1988-05-25
Abstract: PURPOSE:To prevent the remaining melt from spreading on a base plate by receiving the protecting plate covering the base plate on which the growing is carried out into the slide member of a slide board, and keeping the board in the position separated from the base plate when the siding is carried cut. CONSTITUTION:The slide board consisting of a supporting base 10 and sliding member 30 is entered and heated in a furnace in such a state that the base plate 1 is covered with the protecting plate 2, and the melting materials M1-M3 are kept in melted state, and, when a specified temp. is stably kept, the slide member 30 is slided to bring the melt M1 into contact with the base plate 1 to grow the melt M1. Then, by repeating sliding the slide member 30 to grow the melts M2, M3 on the base plate 1, and when all the growing is finished, the slide member 30 is slided again to cover the base plate 1 with the protecting plate 4 and the cooling is carried out. When the protecting plate 4 comes to be moved above the base plate 1, the front end part of the protecting plate 4 in its moving direction is supported so as to be separated from the upper surface of the supporting base 10, and is dropped down on the supporting base 10 when the protecting plate is reached to the position to cover the base plate 1.

Title: Stripping agent
Inventor: SONE TAKAYUKI
IPC: C23F1/00
Filed: 1982-07-23
Abstract: PURPOSE:To enable the control of the stripping rate of a plated layer, by adding a chelating agent to a stripping agent for a plated layer contg. potassium cyanide or sodium cyanide and alkylbenzenesulfonate. CONSTITUTION:A soln. contg. an EDTA compound such as EDTA2K or EDTA 2Na as well as potassium cyanide or sodium cyanide and alkylbenzenesulfonate is used as a stripping agent for a plated layer. When a Cu layer formed by striking is partially plated with Ag, Au or the like and the exposed part of the Cu layer is stripped off, by using the stripping agent having said composition, only the Cu layer part can be thoroughly stripped off while considerably inhibiting the Ag or Au layer from being stripped off.

Title: Semiconductor device
Inventor: TSUNENOBU KAZUKIYO
IPC: H01L21/331
Filed: 1991-05-30
Abstract: PURPOSE:To obtain a semiconductor device which is operated in a high frequency and has a transistor including a high output power by forming a first current terminal and a control electrode on a head of a semiconductor and forming a second current terminal on a base of the semiconductor. CONSTITUTION:A current passage is advanced from a source electrode 21 to the side of a head 15 of a semiconductor, from the side to a center, from the center of the head of the semiconductor to a neck 13 of the semiconductor and to a base 12 of the semiconductor, again advanced at the base 12 horizontally to a drain electrode 25. When a gate voltage is applied to a gate electrode 23 to develop a depleted layer and arrived at an insulator region 14, a current passage from the electrode 21 to the electrode 25 is completely cut OFF. The electrode 25 for removing an output signal is separated from the electrode 23 in which an input signal is applied and isolated by the region 14, etc., and hence a parasitic capacity can be reduced thereby to prevent a short-channel effect by a transistor in which an I-type groove structure is employed and to obtain a semiconductor device having high performance of high output power.

Title: Speed controller for bucket crane
Inventor: TAKIZAWA YOSHIKAZU
IPC: B66C13/32
Filed: 1977-10-25
Abstract: PURPOSE: To heighten the work efficiency, by rotating an open/close motor at a synchronous speed equal to the frequency produced by a support motor to rotate both the motors at almost the same speed when a bucket is opened and lowered by unwinding.  
     CONSTITUTION: When the bucket is opened and lowered by unwinding, electromagnetic contactors 13, 15, 16 are turned on but other electromagnetic contactors 11, 12, 17 are turned off. Releasing brakes 41, 42 in that state, the support motor 1 starts rotating by the weight of the bucket 11. A thyristor 5 is controlled by an automatic controller 4 to have a turn-on angle higher than a predetermined level no matter how a speed command relates to the speed feedback from a command power generator 3. Therefore, a direct current stornger than a predetermined level is flowing through the primary winding of the support motor. When the support motor  starts rotating, its secondary winding poroduces a three-phase AC voltage propartional to the rotational frequency of the motor. Applying the three- phase AC voltage to the open/close motor 2, it rotates at a synchronous speed equal to the frequency produced by the support motor 1.

IPC: G03B21/32
Filed: 1979-10-03
Abstract: PURPOSE: To make possible the simplification of controlling and remote controlling by providing respective touch switches for forward running and backward running and holding relays.

Title: Rotary chopper mirror assembly
Inventor: YAMAGUCHI KATSUMASA
IPC: B23K26/067
Filed: 1984-06-21
Abstract: PURPOSE:To prevent the staining of a rotary chopper mirror and to extend the life of the chopper mirror by providing a filter to cover the vent holes provided through the chopper mirror. CONSTITUTION:The flow of air as shown in air flow 28 is generated on the surface of a reflecting part 23 when the rotary chopper mirror 21 provided with the vent holes 24 is rotated in the rotating direction by a revolving shaft 26. Since the holes 24 are covered by the filter 25, the air flow 28 flowing on the surface of the reflecting part 23 is dust-free air so that the dust-free air flows always on the surface of the part 23 when the mirror 21 rotates. The staining of the surface of the mirror is thus prevented.

Title: Medium voltage circuit breaker with high nominal current
Inventor: DOUNI DEYUFURUNE
IPC: H01H33/91
Filed: 1990-05-17
Abstract: PURPOSE: To reduce the mass of a movable device and to enable savings of the energy required for operating a circuit breaker by providing the movable device including cylindrical members comprising tubes, etc. CONSTITUTION: When a circuit breaker is opened, a tube 22 is moved to the right at a high speed V2. While a tube 30 leaving a finger 3 travels a distance L1 at a speed V1, a movable contact relatively moves a distance L2 longer than the distance L1 at the speed V2 greater than time speed V1. After the main contact 3 and the tube 30 have been separated, a current flows through tubes 4, 15, the contact 13, a tube 9, and a ring 7. Thereby the mass of a movable device is greatly reduced. At the same time, the speed of a movable main contact decreases, resulting in significant savings of the energy required for operating a circuit breaker.

Title: Handling of broken filaments in yarn heat-treating device
Inventor: KAWASHIMA KOUHEI
IPC: D02J1/22
Filed: 1977-10-28
Abstract: PURPOSE: To prevent the heat cohesion of yarn wrapping around rollers in filament breaking, and to improve the operating efficiency, by interlocking the operation of the broken filament detector with the lowering of the preset temperature of the heat-treating rollers.  
     CONSTITUTION: The broken filament detector 4 is interlocked with the temperature indicator controller 7 to control the heating temperature of the heat-setting rollers 3 via the control unit 9. When filaments are broken in the heat treating, the detector 4 detects the breaking and sends actuating signals to the yarn cutter 1 to cut the running yarn Y. Other signals operate the preset temperature contactor 8 of the temperature indicator controller 7 to change over the temperature of rollers 3 to a lower preset one. The preset temperature of the rollers 3 is reduced simultaneously with the detection of broken filaments by the detector 4, thus causing no cohesion of the yarn wrapped around of the rollers 3.
