IPC: H01L21/8247
Filed: 1982-09-24
Abstract: PURPOSE:To improve the electron mobility, and the reproducibility of resistivity of source and drain region of the channel layer of a depletion type element by forming a gate electrode for controlling an electron storage layer formed in the vicinity of the first and second semiconductor layers and an N type region selectively arranged at the position corresponding to the gate electrode of the electron storage layer. CONSTITUTION:A non-doped GaAs layer 12 is formed on a semi-insulating GaAs substrate 11, and a protective film 15 is formed on a semiconductor substrate having an N type AlGaAs layer 13, and an N type GaAs layer 14. Then, impurity ions are implanted to form the channel control region of a depletion type hetero junction field effect element. In order to protect the hetero junction boundary, ion implanted mask employs a laminated structure having a photoresist film 16, a titanium film 17 and a gold film 18. Silicon ions are implanted through the mask, the film 16 is exfoliated and removed, thereby simultaneously removing the films 17, 18. Then, a heat treatment is performed to activate the implanted Si, thereby forming an N type region 20.

Title: Interface controller
Inventor: KUWAYAMA TOSHIO
IPC: G06F13/42
Filed: 1989-06-28
Abstract: PURPOSE:To select a proper clock signal for sampling a reception data automatically by discriminating the sampling result through use of plural kinds of clock signals. CONSTITUTION:A reception data is sampled by a sampling circuit 2 and its start signal is sent to a frequency divider circuit 7 sending 3 kinds of clock signals B-D and a data is inputted to sampling registers 3-5 synchronously with each clock signal. The sampling registers 3-5 are of the constitution of shift registers and latch 10 bits and when the 1st bit of the sampling register 4 is 0 and the 10-th bit is 1, a processor 8 controls a multiplexer in the frequency divider circuit 7 so that the clock signal C corresponding to the speed of the sampling register 4 is fed to an interface transmission/reception circuit 1. Thus, the proper communication speed to the reception data is decided automatically.

Title: Formation of color filter
Inventor: KATO YOSHIHISA
IPC: G02B5/20
Filed: 1995-06-30
Abstract: PURPOSE: To provide a method for formation of color filters which do not induce defects in thin films, etc., formed in the upper parts of the color filters and with which good color characteristics are obtainable by forming both flanks at the sectional shape of the color filters to a trapezoidal shape having optimum slopes. CONSTITUTION: This method for formation comprises exposing a photosensitive color resist film 2 via an exposure mask 4, then subjecting the films to development processing, thereby forming the color filters of prescribed patterns. The spacing between the color resist film 2 and the exposure mask 4 is changed by vertically moving an exposure base 1 during the exposure of the color resist film 2, by which the color resist film 2 is exposed with the light of the intensity distribution meeting the change in the spacings. This light intensity distribution is controlled optimum for the color resist film 2.

Title: Ultraviolet erase eprom
Inventor: YAMADA NORIO
IPC: H01L29/788
Filed: 1990-06-27
Abstract: PURPOSE:To easily prevent a stored data from being destroyed by providing a floating gate type MOS for detecting the decrease of charge at the specified bit of the ultraviolet erase EPROM composed of the floating gate type MOS. CONSTITUTION:A floating gate type MOS 3 is provided for detecting the decrease of charge. This floating gate type MOS 3 for detecting the decrease of charge is one part of floating gate type MOS 3 of multiple bits constituting the ultraviolet erase EPROM. When the EPROM is reloaded, the charge is simultaneously injected to the floating gate, and a second reading voltage to the gate is made close to a threshold voltage rather than the first reading voltage of the floating gate type MOS 2 of multiple bits. Therefore, since the data of the floating gate type MOS 3 for detecting the decrease of charge is inverted before inverting a data stored in the floating gate type MOS 2 of multiple bits, this inversion is detected and the stored data is reloaded. Thus, the stored data can be easily prevented from being destroyed.

Title: Deodorant and deodorizing spray
Inventor: HARAGUCHI TATSUICHI
IPC: A61L9/01
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To enable a deodorant to have a durable deodorizing effect and to effectively prevent dispersion of odor from a dirt, by allowing the deodorant to contain flavonoid and have property of mousse. SOLUTION: A deodorant is prepared so as to contain flavonoid and have property of mousse. In this case, green tea flavonoid extracted from green tea is employed as the flavonoid, and chlorophyll is used combinedly with the green tear flavonoid. Since the deodorant deodorizes bad small of dirt, and at the same time, masks the dirt, a highly durable deodorizing effect can be obtained. Further, if the deodorizer is used in the form of a deodorizing spray, the deodorizer can be easily sprayed apart from the dirt, so it is very convenient. In addition, since the green tea flavonoid is natural deodorizer and not harmful to a human body, the deodorizer can be used safely without any anxiety.

Title: Heat exchanger type vacuum distillation and drying device
Inventor: OKABE SHUICHI
IPC: B01D3/10
Filed: 1993-06-14
Abstract: PURPOSE:To cope with materials to be treated over a wide range and to unnecessitate a heat source for heating and cooling by providing an evacuated chamber into which the materials to be treated are charged and a pressure chamber to which gas in the evacuated chamber is transferred and providing a recovered material discharge port for each chamber. CONSTITUTION:After materials to be treated are charged into a vacuum chamber from a throw-in hole 5 and the vacuum chamber 1 is made in a closed state, a l pump 3 is driven to transfer gas in the evacuated chamber 1 to a pressurized chamber 2 through a transfer line 4. The pressure in the evacuated chamber 1 is lowered by this work to boil and evaporate materials having a lower boiling point than that of the materials to be treated housed inside, such as water by vacuum action without being heated. The evaporated low boiling 4 materials enter the pressurized chamber 2 by the transfer line 4 through the pump 3 and are easily condensed and liquefied in a compressed state in the presstrized chamber 2 without being cooled and accumulated in the presstrized chamber 2. At this time, heat of condensation is generated and is conducted into the evacuated chamber 1 through the wall of the evacuated chamber 1 to compensate heat of vaporization for evaporation in the evacuated chamber 1.

Title: Switching power supply
Inventor: KOYAMA OSAMU
IPC: H02M3/28
Filed: 1995-07-04
Abstract: PROBLEM TO BE SOLVED: To obtain a power supply for an apparatus having an operation waiting mode in which the operating point of an overcurrent protective circuit can be varied on standby of the operation. SOLUTION: While being on standby of the operation, a control signal is transmitted from the secondary through a photocoupler to a transistor 111 in an overcurrent set value adjusting circuit 11 and the transistor 111 is turned off. Consequently, an overcurrent detection resistance is determined only by a current detection resistor 102 and an overcurrent protective circuit functions with low power consumption as compared with normal operation. If an electric abnormality occurs on the load side under that state to cause a current flow exceeding the maximum current of normal load, a control transistor 101 is turned on and the base or gate voltage of a switching element 1 is lowered below a threshold level. Consequently, the switching operation is stopped and the output voltage goes zero thus protecting an apparatus against failure.
