Title: Grill oven range
Inventor: TANABE TAKESHI
IPC: H05B6/80
Filed: 1981-12-01
Abstract: PURPOSE:To obtain an adequate grill cooking by a grill oven range adapted to be automatically controlled according to the kind of the food to be cooked by a consturction  wherein the heater is provided with a projection having a high heat conductivity and  the heater is raised when the change in the output of a gas sensor exceeds a predetermined value. CONSTITUTION:Upon completion of high frequency heating, an electric current is sent to a heater 4, a damper is closed, the output power ratio of a gas sensor 11 is discriminated again, and its output signal level VZ is stored in RAM of microcomputer.  Subsequently, a motor (not shown) for raising and lowering the heater 4 is rotated forwardly to lower the heater 4 by a predetermined distance, and the output VY of the gas  sensor 11 at that time is stored in RAM of the microcomputer. Then, when the ratio  VY/VZ reaches a value less than 0.02, it is judged that a projection 4' of the heater 4  has contacted with the food being cooked, and the motor (not shown) is rotated reversely to raise the heater 4 by a predetermined distance. Application of electric current is continued for a predetermined heating time. If the ratio is more than about 0.02  and the amount of lowering is too small, the procedure is repeated. By this arrangement, intrusion of the heater into the food can be prevented and an adequate heating  can be performed.

Filed: 1988-08-05
Abstract: PURPOSE:To prevent irradiation of laser light to the outside of an assigned marking range even if an optical scanner or the controller thereof goes out of order by providing a mask for light shielding between the optical scanner and a processing surface. CONSTITUTION:A condenser lens 12 for condensing the laser light reflected by a beam splitter 10 and a photosensor 13 for detecting the laser light are added.

The mask 4 is irradiated with the laser light within the marking range thereof and the polarization plane of the laser does not change when the scanner is normal. Then the laser transmits the scan lens and the beam splitter and arrives onto the work to be printed.

IPC: H04L25/02
Filed: 1989-07-26
Abstract: PURPOSE:To measure resistance in a short time as required at any time by measuring a resistance during network operation. CONSTITUTION:A measuring timing control section 7 checks information representing a packet received at first from a carrier sense section 3 in the case of measurement and awaits till packets are lost in the case of presence of packets and gives an output command for measuring signal to a measuring signal output section 5 immediately in the case of absence of packet or when the packet is lost. Then the measuring timing control section 7 gives a command of resistance calculation to a resistance calculation section 6 after the lapse of time Tmax, and gives a command of measuring signal output stop to the measuring signal output section 5 after the resistance calculation section 6 finishes calculating the resistance. Thus, the resistance is measured in a short time as required.

Abstract: PROBLEM TO BE SOLVED: To provide a steering device for a vehicle not only capable of changing a steering gear ratio in accordance with a steering angle of a steering wheel, but capable of optionally setting an steering angle characteristic suitable for the vehicle and extending freedom of design. SOLUTION: A steering device 10 for a vehicle is furnished with a rack bar 22 and a disc 30 to axially move by steering of a steering wheel 24, and an eccentric pin 36 of the disc 30 is put in a slit 46 of an oscillating link 42. When the rack bar 22 axially moves, the disc 30 is rotated while axially moving, the eccentric pin 36 oscillates the oscillating link 42 and a turning rod 12 is driven. As the eccentric pin 36 is rotated while axially moving, actual moving quantity increases, a pressurizing position of the oscillating link 42 is changed, and a lever ratio is changed. Consequently, a steering gear ratio is changed in accordance with a steering angle of the steering wheel 24.

Title: Picture data reading circuit
Inventor: FUJIMOTO YOSHIHIRO
IPC: G06F3/153
Filed: 1984-09-17
Abstract: PURPOSE:To decrease the number of shift registers by storing the picture data read out of a frame memory to a temporary memory circuit by a certain number of bits and giving the picture data to a shift register to shift them in time division and to convert shifted data into the bit-serial picture data. CONSTITUTION:Four 8-bit latches 101-104, for example, are connected to the output of a frame memory 8. These latches constitute a temporary memory circuit for every 8 bits in case the 32-bit picture data read out of the memory 8 is divided into four parts. The latch signals are supplied to those latches in common with each other together with the output enable signals. The outputs of latches are connected in common to a shift register 105 together with supply of both load and clock pulses. Then the picture data stored in each temporary memory circuit is shifted in time division and converted into the bit-serial picture data. In such a way the number of shift registers is decreased, and can read the picture data out of the memory 8 with high stability and without delaying the load pulse or clock pulse.

Title: Manufacture of semiconductor substrate
Inventor: FUKAMI AKIRA
IPC: H01L21/02
Filed: 1986-08-22
Abstract: PURPOSE:To enable single-crystal silicon of a large area to be formed on an insulating layer without occurrences of condensation, depletion, and cut-out stages, by forming a heat absorptive layer or a high-heated conductivity layer on the upper part of a polycrystal or amorphous semiconductor layer through an insulating layer having a partial opening. CONSTITUTION:A mask resisting an atmosphere of oxide such as silicon nitride is mounted on a partial surface of a silicon substrate 1 and followed by heat oxidation, so that a silicon oxide film 20 is formed on the surface. Successively, the mask of silicon nitride is removed to expose the surface part which is not oxidized and polycrystal silicon 30 is piled on this part by a vapor growth method. This polycrystal silicon 30 is recrystalized to become a single crystal in the later process, however, at that time the part, where the silicon on the substrate is exposed without being oxidized, functions as core crystal 4. After polycrystal silicon 30 is piled, a silicon oxide film 21 is piled by a vapor growth method and then the silicon oxide film, which is formed in the area a little larger than the area of the core crystal 4, is removed and then a polycrystal silicon 31 is piled again. After such composition, the polycrystal silicon 30 is dissolved and recrystalized.

Abstract: PURPOSE:To obtain an electric current regulator for a welding machine which is simple in construction and is low in manufacturing cost, by starting a motor for regulation of electric current with the output of a discriminating circuit and determining the revolving directions thereof according to the electric current directions of an operating element. CONSTITUTION:In the case of increasing electric current, a rectifier RF1 contg. one end of an operating element is so connected to a holder HL as to direct the direction A and the other end is connected to a base material BM, then a discriminating circuit CL is closed via the operation element. The current flows only to the circuit where the direction of the rectifier RF1 and the directions of the rectifiers RF2, RF3 in the discriminating circuit coincide; therefore, only the series circuit of the rectifier RF2, that is,a relay U, is energized and operated. Thereupon, contacts U2 are closed, and an AC power source conduct electricity to the circuit of a coil RUC, then the relay RU operates. Contacts RU1, RU2 are closed, and the current is applied to a motor M for regulation of current so that the iron core of the main windings of a welding transformer T is moved in the direction toward increasing of the welding current.
