Title: Erroneous erasure and write prevention system for memory card
Inventor: SAKAMOTO TAKASHI
IPC: G06K19/073
Filed: 1989-06-23
Abstract: PURPOSE:To prevent data in a memory card destroyed by preventing erasing and writing on the memory card by providing a mechanism to prevent erroneous erasing and writing at the memory card, providing a detector to detect the state of the above prevention mechanism at a card reader, and transmitting the output of the detector to a central processing unit.

Title: Control circuit for ac power semiconductor switch
Inventor: MIURA SHIYUNJI
IPC: G05F1/10
Filed: 1977-12-29
Abstract: PURPOSE: To operate a characteristic element at or near the zero point of power voltage by using the caracteristic element which has the voltage and current characteristics to apply current in accordance with the polarity of applied AC voltage when the absolute value of the applied AC voltage is smaller than its prescribed value.  
     CONSTITUTION: Characteristic element A to apply current in accordance with the polarity of applied voltage when it does not exceed its prescribed value and not to apply current when it exceeds the prescribed value is connected to light receiving element PC. When AC voltage is applied between AC1 and AC2, this voltage is applied to both ends of TRIAC and the characteristic element A. If DC voltage is not applied between P and N in this case, TRIAC goes OFF and current is not applied to a load. On the contrary, if voltage is applied between P and N, PC2 receives light input and goes into low resistance status. When the characteristic element A operates within the range of -V o  to +V o , current is applied to the TRIAC gate electrode G3 and ignites it. Then current is applied to the load in accordance with the polarity of input AC voltage.

Title: Device and method for detecting air-fuel ratio in broad range based on work function
Inventor: ROBAATO II HETSUTORITSUKU
IPC: G01N27/00
Filed: 1993-06-29
Abstract: PURPOSE: To detect air/fuel ratio over a wide range especially around the theoretical air/fuel ratio of the exhaust gas from an automobile by combination of the oxygen pumping and the measurement of variation in the work function on the surface of a working electrode. CONSTITUTION: The emission surface 11 of a sensor is composed of a porous layer of alkaline metal doped platinum and serves as the working electrode of an oxygen concentration cell 12. The work function on the surface is varied from a large value to a small value as the oxidative and reductive species in gas phase make transition from an over oxidative species state to an over reductive species state around a theoretical air/fuel ratio. The emission surface 11 is heated by a heater 14 to emit thermal ions which are collected by a collection electrode 15. Variation in the air/fuel ratio around a theoretical air/fuel ratio corresponds to variation in the thermal ion discharge current I and the oxygen pumping current IP of a chemical cell modulates the thermal ion discharge current I. Consequently, the air/fuel ratio can be detected over a wide range by detecting the magnitude of pumping current IP required for sustaining the thermal ion discharge current I at a preset level regardless of variation of the air/fuel.

Filed: 1990-06-20
Abstract: PURPOSE:To ensure that the opening and the shutting of a door of an additional device is judged without fail with the number of signal wires installed between the additional. device and the main body of the title device minimized by a method wherein the judgement is made to judge whether the door is open or shut in accordance with the level of an output part of a control means while a driving means is turned off with the control means that controls on-off of the driving means. CONSTITUTION:As a power source of a device main body 1 is switched on, output from a control section 17 is cut off. With a multicassette feeder 3a attached to the device main body 1, 24V electricity is supplied from a terminal Pa to a terminal on one end of a solenoid SD through a switch SW, and is further supplied to resistors Ra1, Ra2 through the solenoid SD. Therefore the state of attachment of the multicassette feeder 3a can be judged by the level at a connecting point between the resistors Ra1 and Ra2. As a door provided to the multicassette feeder 3a opens, the switch SW is opened. Then supply of the electricity from the terminal Pa to the resistors Ra1 and Ra2 is cut off and because of this, the level at the connecting point between the resistors Ra1 and Ra2 becomes low. Then the judgement can be made that the door of the multicassette feeder is open.
