Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To attain storage protection and secrecy holding for a program or the like with respect to a data processor provided with a main storage part consisting of a non-volatile memory and a CPU. SOLUTION: An auxiliary storage part for storing security bit data is included in an erasable programmable read-only memory(EEPROM) constituting a main storage part e.g. When the read result of the CPU at the time of allowing a current to flow between the drain and source of a transistor(TR) in the EEPROM is set up to '0' and a read result when the current is not allowed to flow is set up to '1', security bit data read out from two TRs A, B are A=1, B=1 and an access to the main storage part and writing in the auxiliary storage part are set up so as to be inhibited. When A=0 and B=0, security is applied but writing in the auxiliary storage part is permitted, and when A=1(0) and B=0(1), security is set up so as to be released.

Abstract: PURPOSE:To attain communication between terminal equipments with different attributes by trying a call connection via a transmission format conversion section and providing a control means for setting a path between terminal equipments at the time of occurrence of incoming rejection due to the dissidence of attributes. CONSTITUTION:In an electronic exchange 10, when a call set command is sent from a terminal 11, an exchange control section 51 receives call setting and acquires a time slot and informs an incoming call to a terminal 12.

Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To prevent impurities from diffusing unevenly to a gate insulation film by forming a gate electrode of a semiconductor device which has a semiconductor element provided with a gate electrode through a gate insulation film on a semiconductor substrate of semiconductor crystal of a specified conductivity type. SOLUTION: A pair of semiconductor regions 3n1 are formed apart in an upper part of a p-well PW, a gate insulation film 3ni is formed on a semiconductor substrate 1 and a gate insulation film 3ng is formed thereon for forming an nMOS 3n. If the gate insulation film 3ng is formed of Si single crystal containing impurities, for example, crystalline grain boundary does not exist in the gate insulation film 3ng. Therefore, when a gate electrode is formed of low resistance polycrystalline silicon, impurities contained in crystalline grain boundary in a gate electrode at a high concentration is prevented from diffusing unevenly to the gate insulation film 3ni.

IPC: F16N7/38
Filed: 1978-04-21
Abstract: PURPOSE: To prevent reduction in lubricating pressure with a simple oiling pressure adjusting means by connecting an auxiliary feed tube to a head tank via a position higher than the tank enough to make possible the replenishing at the position head between the highest level of the tube and the bearing.  
     CONSTITUTION: During the operation of a lubricating pump 1, a lubricant is fed by the pump continuously to the bearing of an exhaust turbo-supercharger 3 while a position head is applied between the highest level of an auxiliary lubricating tube 13 and the bearing. With such an arrangement, even when a sudden change in the rotation speed of the supercharger 3 and the like happens, variation of the lubrication pressure is almost eliminated from the bearing. In case the lubricating pump cause a trouble, a check valve is opened to allow the lubricant in a head tank 15 to be fed to the bearing via a replenishing oil tube 16. In this manner, the lubricating pressure can be adjusted with a simple means thereby securing the lubrication of the bearing and ultimating preventing burning thereof.

Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To miniaturize a liquid crystal display device by providing this device with a battery housing section on the side opposite to the display window of a case, disposing plural batteries directed toward the thickness direction which is a display window side in this section and disposing the more batteries than these batteries along the case. SOLUTION: Two pieces of the batteries are disposed in the direction H which is the thickness direction on the battery lid 64 side from the display window side of the liquid crystal display device 100 and the thickness direction of the battery housing section 51. The polarities of the batteries lined up in the thickness direction are directed to the same direction to prevent the batteries lined up in the thickness direction from being hooked by a spring having a projecting shape at the time of removing the batteries from the battery lid side. Further, the number of the batteries to be disposed is specified to two pieces in the thickness direction and three pieces on the side of the battery lid 64, by which the number of the batteries disposed on the battery lid 64 side is made larger than the number of the batteries disposed in the thickness direction.  As a result, the need for lining up the batteries to one row is eliminated and the plane size of the liquid crystal display device is reduced without decreasing the number of the batteries, i.e., without shortening the battery life.

IPC: B41J29/377
Filed: 1993-03-09
Abstract: PURPOSE:To prevent a head from heating up and to reduce a print waiting time. CONSTITUTION:A thermister 25 is attached to a thermal head 15. A temperature signal of the thermal head 15 detected by the thermister 25 is transmitted to a differential amplifier 27 via a voltage conversion circuit 26 and the difference between the detected value and a specified temperature is outputted as temperature data. In accordance with the temperature data, a fan speed setting circuit 30 controls a rotation speed of a motor 32 via a motor driver 31. The higher the temperature becomes, the faster a cooling fan 20 rotates to blow greater amount of air to the thermal head 15. When the temperature data becomes lower than the specified temperature, the rotation of the cooling fan 20 is stopped.

Title: Film photographing device
Inventor: HIRANO REIJI
IPC: A61B3/14
Filed: 1983-03-22
Abstract: PURPOSE:To make easily a photographer recognize the end of a film and to prevent the trouble about a camera by voicing which informs the film end when a photographing switch is pressed at the end of film. CONSTITUTION:When a film ends, a light emission timing signal S6 is generated at the timing of the application of a shutter release signal S2 during the next photographing operation, and the output generates a film end signal S7. This film end signal S7 is inputted to a speech synthesizing means 5, which outputs a voice signal S8 in preset order; and the signal is amplified by a voice signal amplifier 6 and a voicing means SP voices the film end. Thus, the exhaustion of the film is indicated by a voice, so this is extremely effective for a photographer who concentrates his attention on a subject.
