Title: Heating and cooking device having temperature sensor
Inventor: INOMATA MASANOBU
IPC: F24C3/12
Filed: 1991-04-09
Abstract: PURPOSE:To improve a convenience for handling by preventing an automatic fire extinguishing under a pan application when a temperature cut mode is set. CONSTITUTION:In the case that a temperature difference of a sensed temperature of a temperature sensor 8 for every specified time measured by a measuring circuit 10 and stored in a memory circuit 11 is higher than a reference temperature difference, it is judged that a pan application is made, and a high-cut, i.e., an automatic distinguishing of fire of a gas burner 2 is not carried out even if a sensed temperature of the temperature sensor 8 is increased higher than the cut temperature.

Title: Circuit for protecting error detection
Inventor: MIYANO YUICHI
IPC: G11B20/18
Filed: 1988-03-31
Abstract: PURPOSE:To surely perform error detection even when a fault occurs in the synchronism detection, protection, or interpolation of reproduce signals in a writing state and writing of the block data is not performed, by creating a state where the data of the corresponding area in a memory are destroyed. CONSTITUTION:A buffer memory 20 is prepared for temporarily storing reproduced data and its two areas are alternately switched in such a way that while one area is switched to the write state the other area is switched to the read state. Read out data are stored in output registers 23 and 24 through an input register 22. After performing an error detecting and correcting processes on the reproduced data written in the buffer memory 20 and the data are read out, the data remaining in the memory 20 are changed so that date in the memory cannot be destroyed even if the synchronizing signal of the next write data cannot be detected and the data in the memory are not updated. Therefore, error detection is certainly performed and the error detecting and correcting capacities can be improved.

Abstract: PURPOSE:To reduce the loss of coupling with an optical fiber by directly joining light-transmissive substrates which have the same refractive index across a layer which has a lower refractive index and providing one of the substrates with an optical waveguide to which light is confined. CONSTITUTION:The substrate 1 which transmits light and the substrate 2 which has the same refractive index with the substrate 1 and is low in light transmissivity are joined together directly across the low-refractive-index layer 3. Further, an input/output optical waveguide part 4 formed on the substrate 2, and one branch optical waveguide 4 and the other branch optical waveguide 6 that the input part branches into are provided and electrodes 7 and 8 are provided on both the sides of the branch optical waveguide 6. Then light which is made incident from the input part is split into two, the optical waveguide parts are made different in refractive index by electrooptic effect by applying an electric field to the optical waveguides to vary the propagation speed of guided light, and lights at a recoupling part are made different in phase, thereby modulating the intensity of the light of an output part. Here, silicon oxide is used for the low refractive index layer 3, which is made lower in refractive index than the substrates 1 and 2 to confine the light to one substrate.

Title: Dry etching method
Inventor: SATO JUNICHI
IPC: H01L21/302
Filed: 1991-03-18
Abstract: PURPOSE:To increase the anti-resist selectivity and anti-base selectivity and to facilitate the maintenance of an apparatus, concerning the etching of an Al-based material layer. CONSTITUTION:A wafer is cooled to -60 deg.C, and first the naturally oxidized film 7 on the surface of an Al-1% Si layer 6 is removed using a BCl3/Cl2/WF6 mixed gas. Next the Al-1% Si layer 6 and barrier metal 5 are etched using a Cl2/WF6 mixed gas. Highly anisotropic processing can be accomplished even under a low bias condition since WFX dissociated from WF6 is deposited on the cooled wafer and protects the side walls. After the etching, the wafer is heated and the WFX is volatilized and removed. As reducing BCl3 is not used in the etching of the Al-1% Si layer 6, the selectivity to an interlayer insulating film 1 being the base increases, and a large amount of B2O3 is not precipitated in the exhaust system of the apparatus.

Abstract: PURPOSE:To constitute a titled radio equipment so that its unnecessary radiation cannot be executed easily by emitting a signal of a prescribed band width only when a cipher code set in advance is received. CONSTITUTION:In case an additional circuit 2 is not connected to a radio part 1, a switch 12 of the radio part 1 remains opened, therefore, even if a power source 13 is turned on, a transmitting part 11 does not operate and the radio part1 does not function. Subsequently, when the additional circuit part 2 is connected to the radio part 1 through a multi-core cable 3, a base band circuit 21 and a coder 22 are started by a power source 23. A cipher code set in advance is inputted to a decoder 14 through the multicore cable 3 from the coder 22. The power source 13 is connected to the decoder 14 and the switch 12. Accordingly, the decoder 14 decodes the incoming code, sends out an operating signal to the switch 12 since said code coincides with a prescribed code, and the switch concerned 12 is closed. The transmitting part 11 is connected to the power source 13 through the switch 12, therefore, a signal of a prescribed band width transmitted from the base band circuit 21 is loaded on a carrier wave and modulated, and the modulated wave is amplified and radiated from an antenna 16.

Filed: 1987-03-30
Abstract: PURPOSE:To improve access efficiency by adding an address arithmetic circuit to an input part for address information and a data rotating circuit to a data input/output part respectively. CONSTITUTION:The M pieces of address arithmetic circuits 20-2M-1 convert the address information into different values according to their own positions and send these different address information to M pieces of memory modules 30-3M-1 connected to each other. A data rotating circuit 4 is connected to the modules 30-3M-1 at one side of the circuit 4 and to a data bus 5 of M-bit width at the other hand with rotation according to the value of the address information received from an address bus 1 set separately. Then the circuit 4 transfers the M-bit data information all at once from the left to the right and vice versa. Thus it is possible to use effectively the bits in a word to receive an access against the data information arranged horizontally and vertically in case the two-dimensional information is stored. In such a way, the access efficiency is improved.
