Title: Method of controlling power converter
Inventor: NAKAJIMA KIHEI
IPC: H02M7/48
Filed: 1984-09-19
Abstract: PURPOSE:To improve the responsive characteristic for an abrupt variation of a DC power source by varying the output voltage phase of an inverter when a deviation between the output voltage command value of a chopper and the output voltage exceeds the prescribed value. CONSTITUTION:A DC power source 1 of a solar light generator is connected through a chopper 2, an inverter 3, and an AC reactor 4 with an AC power source 5. The chopper 2 has a regulator 5 for converting the voltage of the power source 1 to the prescribed DC voltage V2, and the inverter 3 has an inverter phase controller 7 for controlling the output voltage phase. In this case, the controller 7 has a phase difference setter 8, a pulse generator 9 and an adder 11, and a phase correcting circuit 10. Thus, the phase difference thetabetween the AC power voltage and the output voltage of the inverter becomes the value added with the original value by the setter 8 and phase difference theta' output from the correcting circuit 10 when the power source 1 abruptly drops, and the output voltage of the inverter drops in the fast response to prevent the DC voltage V2 from excessively decreasing.

Title: Paper sheet separating device
Inventor: KAWAGUCHI KATSUHIKO
IPC: B65H3/46
Filed: 1994-08-22
Abstract: PURPOSE: To promote a paper sheet separating action and facilitate the jamming treatment. CONSTITUTION: Paper sheets S delivered by an intermittently driven paper feed roller 11 are separated between a driven rotating element 23 which slave- rotates by friction in a space to the paper sheet S, and a separating element 24 whose outer periphery surface is at least formed out of high friction material. By forcing the separating element 24 to the driven rotating element 23 and mounting it so as to approach and separate from the driven rotating element 23, frictional resistance against the paper sheet S is increased even if the thickness of the paper sheet S changes a little, thus promoting the separating action of the paper sheet.  By rotatingly-supporting the separating element 24 in a range of fixed angle, if plural paper sheets S are caught between the driven rotating element 23 and the separating element 24, it is possible to separate the separating element 24 from the driven rotating element 23 and rotate it to the paper feed roller 11, thus assuring easy removal of the paper sheets S.

Filed: 1988-08-05
Abstract: PURPOSE:To reduce heat dissipation from a reaction chamber to set temperature uniformly at each section in the reaction chamber by providing a heat blocking member on the inside surface of the reaction chamber not heated by a heater. CONSTITUTION:Inside surface of a handle section door 2 and a source section door 3 are coated with high temperature sintered ceramics 9 having lower thermal conductivity than stainless. When a wafer 8 is heated by a handle section heater 4, an outer section heater 5, and a source section heater 6, heat dissipation is more restricted compared with prior cases. Thus, a temperature hysteresis at each section in a reaction chamber 1 is made the same and temperature at each section in the reaction chamber 1 is set uniform.

Abstract: PURPOSE:To decrease the reduction of a field oxide film in a buffer-oxide-film removing process, a gate-oxide removing process and the like, by forming the field oxide film, nitriding the surface of the field oxide film and forming an etching resisting tnin film. CONSTITUTION:For example, a buffer oxide film 22 is formed on a P-type silicon substrate 21. Then, an Si3N4 film 23 as an oxidation resisting film is formed at an element forming part of te buffer oxide film 22. With the film 23 as a mask, field oxidation is performed, and a thick field oxide film 24 is formed. After said Si3N4 23 is removed, the entire wafer is annealed at 1,100 deg.C in ammonia gas for one hour. As a result, the surfaces of said field oxide film 24 and buffer oxide film 22 are thinly nitrided, and a nitrogen monoxide (NO) film 26 is formed. Therefore, the NO film 26 works as a stopper in the following removing and washing processes of the buffer oxide film 22 and a gate oxide film 28. Thus the reduction in the field oxide film 24 can be strikingly decreased.

Title: Call signal generation circuit for telephone
Inventor: UEDA TAKEHIKO
IPC: H04M3/02
Filed: 1990-07-25
Abstract: PURPOSE:To miniaturize the whole shape by making a heat insulating board small by eliminating the sense of incongruity by generating a call tone of sine wave in an ordinary operation, and reducing power consumption by generating a call tone of non-sinusoidal wave when an overload is applied. CONSTITUTION:A current detection circuit 20 detects an overload state by a current on the resistor R of a driving circuit 2. The output of the circuit 20 is inputted to a CPU 11 via an amplifier 21 and an A/D converter 22. The CPU 11 outputs the sine wave as a call signal when a power shows a valve less than a prescribed value, and generates the call tone without generating the sense of incongruity. Meanwhile, when the power is increased than the prescribed value and it is decided that the overload state of the circuit 2 is recognized, a signal near to a square wave is outputted as the signal, and the power of the circuit 2 is reduced. Thereby, it is possible to miniaturize the whole shape by making the heat insulating board small.

A same operation is executed in the case the registered code area is desired to be corrected and erased and 'memory' is depressed after dials are cleared by 'clear' at the time of erasion. When the 'power source' of the key 2 is depressed, the registered first area code 030 is displayed and the second are code 045 is displayed by depressing the 'power source' again.  After the display of the area code, the dials are inputted and the telephone number is continuously inputted.

Abstract: PROBLEM TO BE SOLVED: To include a glass layer and to improve flexibility by a method in which the first and second layers are included, the first layer is a glass layer, and a crack line is formed in the glass layer. SOLUTION: A laminate 50 includes a glass layer 10, the second layer 20, and an additional glass layer, the glass layer 10 is laminated on the surface 21 of the second layer 20, and the additional glass layer 40 is laminated on the surface 24 opposite to the surface 21 of the second layer 20. Crack lines 11, 41 are formed in the glass layer and the additional glass layer 40, respectively. The crack lines are arranged in a hexagonal pattern and have a depth equal to the thickness of each glass layer. When the laminate is deformed, in the glass layers, each hexagon can move around the crack line. Especially, when a hexagonal elements are small enough, the flexibility of the laminate is determined chiefly by the flexibility of the second layer 20 which is a polymer layer and others. The laminate 50 having good flexibility can be obtained by this method.

Title: Combination system for plural processors in character recognizing device
Inventor: IKEDA EIJI
IPC: G06F15/167
Filed: 1990-07-27
Abstract: PURPOSE:To remarkably shorten down-load time by simultaneously down-loading a program and a character recognizing dictionary to respective slave processors with a master processor. CONSTITUTION:Just after the power source is supplied, the program developed in the memories of the respective processors, the character recognizing dictionary, etc., are stored in an external memory device 5. When the power source is supplied, a master processor 1 reads data from the device 5 successively, checks the allotment destination, and transmits data other than the program data developed in the memory of its own through a bi-directional accessible dual port memory 6 to all slave processors 2 to 4 simultaneously. Respective processors 2 to 4 check the transmitted data to develop to the memory of their own when the allotment destination is for themselves, and neglect this when it is not for themselves. Thus, the time for down load can be remarkably shortened.
