Title: Heater cooking appliance
Inventor: IKEDA NOBUO
IPC: F24C15/32
Filed: 1985-06-07
Abstract: PURPOSE:To enable a uniform cooking of food having non-uniform thickness to be performed with a grill even in a turn-table type heater cooking appliance by a method wherein a hot- air circulation fan is rotated, stopped or intermittently operated during a grill cooking operation. CONSTITUTION:Each of a grill heater 2, hot-air circulation heater 10 and hot-air circulation motor 9 is controlled for its ON and OFF conditions through relay contact points S2, S3 and S4, respectively. Each of the relay contact points is turned ON or OFF through each of the relay coils R2, R3 and R4. A control part 14 controls each of the relays. When a cooking in grill is performed, a depressing of the grill key constituting the control part 14 causes only the relay contact points S2 and S1 to be turned ON and its another depressing causes the relay contact point S4 to be turned ON simultaneously with the operation of the relay contact points S2 and S1 and then the hot-air circulation fan 8 is rotated. When the hot-air circulation fan 8 is operated, the air in the heating chamber 1 is circulated as shown by an arrow, so that the temperature in the heating chamber is made uniform and the non-uniform food can be substantially uniformly cooked in grill.

Title: Solid-state image pickup device
Inventor: TERANISHI SHINICHI
IPC: H04N5/335
Filed: 1996-05-21
Abstract: PROBLEM TO BE SOLVED: To prevent degradation of sensitivity and production of moir* by installing a correspondent micro-lens on each of the photoelectric conversion sections of a solid-state image pickup device, which are arranged on the major surface of a semiconductor substrate in two-dimensional lattices, and installing an optical fiber handle having optical fibers arranged in two-dimensional lattices attached thereon. SOLUTION: Light incident on an optical fiber handle 42 is propagated through a core 43, and enters micro-lenses 11 through a filler 41. It is then focused on photoelectric conversion sections 1, and is subjected to photoelectric conversion into a signal charge. The virtual aperture rate of the photoelectric conversion sections 1 is increased by two or three times using the micro-lenses 11 to enhance sensitivity. Further, for nonuniformity of sensitivity due to difference in type and periodicity between the lattices of the photoelectric conversion sections 1 and the lattices of the core 43, the ratio of maximum sensitivity to minimum sensitivity is reduced, and thus moir* arising from such non- uniformity of sensitivity is significantly reduced. This enhances the virtual aperture rate, light utilization factor and sensitivity.

Abstract: PURPOSE:To simplify the circuit constitution by outputting an ignition signal at the time point when the second integration voltage having the wave form which increases by a certain voltage at the max. advance position and rises at a certain gradient reaches the first integration voltage having the wave form which increases by a certain value at the position advancing from the max. advance position and then lowers. CONSTITUTION:A signal coil 5 generates the first and the second signals VS1 and VS2 which become the prescribed threshold values or more at the position having the advanced phase than the max. advance position and at the max. advance position, and the first integration voltage VC1 is obtained by the integration of the signal VS1 which lowers at a certain gradient by the first integration circuit 6a, and the second integration voltage VC2 is obtained by the integration of the signal VS2 which increases at a certain gradient by the second integration circuit 6b. When the integration voltage VC2 reaches VC1, an ignition signal Ig is outputted into the primary current control circuit 3 from a signal output circuit 6c. Therefore, the need for installing a circuit for limiting the ignition timing between the max. and min. advance positions in a signal output circuit is avoided, and the circuit constitution is made simple.

Abstract: PURPOSE:To easily perform the counting of sheets and to obtain necessary information for double-sided copying by providing an automatic document feeder with a counting function. CONSTITUTION:When a key 87 is turned on, a slave processor 102 receives the instructions of a master processor 101. The documents on a sheet supplying tray are taken in one by one from an upper side and fed, and jam check is performed. The counting of the number of the sheets is performed by incrimenting together with the opening and closing of a jam switch 482 when the documents are ejected. The number is inputted into the processor 102 through an interface 121. EEPROM120 becomes '0' by means of a clear key 84. The number is counted until a switch detects there is no sheet. The occurrence of jamming is displayed in a displaying part 111. When the switch 45 is turned off, the processor 102 reads the contents of a ROM120, sends a document number counting information signal to the main processor and displays the contents in the displaying part 111. A user can visually confirm the number of the sheets. The counting mode of the processor 101 is released by means of the clear key 84 and an ordinary copying mode is set. In the constitution, the counting of the sheets can easily be performed and the necessary information for double-sided copying can easily be obtained.
