Title: Manufacture of austenite steel sheet having excellent resistance to oxidation
Inventor: MAKINO YOSHIHISA
IPC: C22C38/00
Filed: 1979-07-24
Abstract: PURPOSE:To manufacture austenite steel sheet with excellent resistance to oxidation, having no edge crack, by hot rolling of continuously cast slab of Cr-Ni alloy  steel of very low S content and high Si content at a specific temp. and a specific  conditions for rolling reduction. CONSTITUTION:Cr-Ni alloy steel of high Si content consisting of <0.10% C, <5% Si, <2% Mn, 9-15% Ni, 17.5-25% Cr, <0.003% S, or in addition, 0.0010- 0.0060% Ca is made into a slab by continuous casting process. The slab is hot rolled at 1,200-1,250 deg.C temp. and at <=30% reduction ratio to manufacture steel sheet and is wound into a coil. The steel sheet has stable austenite structure due to Ni contained in it, and has excellent resistance to oxidation because of the Cr content, very small S content, and by the treatment with Ca. The limitation of heating temp. for hot rolling to 1,200-1,250 deg.C temp. range allows to prevent the formation of edge crack in the steel sheet during hot rolling.

Title: Comparative detector
Inventor: NAKANE SHINICHI
IPC: G01D3/024
Filed: 1980-07-10
Abstract: PURPOSE:To make comparative detection of good accuracy possible for a sensor having a wide range of resistance change by fixing reference potential roughly at the intermediate potential of an electric power source and operating the comparing potential side including sensor like pulses. CONSTITUTION:The signal of a pulse oscillation part 10 is transmitted via resistances 11, 12 to a transistor 13 which is a switch means, and a resistance 25 is connected in parallel and disconnects to a resistance 24 connected in series to a sensor 5. Thereby, the comparative input potential of a comparator 14 is made pulse voltage. The reference potential of the comparator 14 is set roughly at the intermediate of source voltage E by resistances 26, 27. For example, when a combustion state is detected by using TiO2 as a sensor 5, the output of the comparator 14 is a low level until the ignition is detected  but the sensor exposed to a high temp. atmosphere after the ignition decreases its resistance value owing to thermistor characteristics and a pulse signal is generated in the output of the comparator 14. Further when the sensor goes into a flame in the state of oxygen default, its resistance sharply decreases and the output of the comparator 14 is fixed at a high level.

Title: Dynamic vector detecting device
Inventor: TANOI HISAYUKI
IPC: H04N19/543
Filed: 1989-04-17
Abstract: PURPOSE:To detect an exact dynamic vector by detecting the dynamic vector by block matching with respect to an image signal obtained by cutting a spatial high frequency component of a dynamic image signal. CONSTITUTION:A dynamic image signal (a) is cut as to its spatial high frequency component by a two-dimensional low-pass filter circuit 2. Subsequently, in a dynamic vector detecting circuit 3, an evaluation function is calculated with respect to thinned-out picture elements (for instance, 32 picture elements by thinning 1/2) in an MC block at every MC block. By what is called block matching, a dynamic vector is detected. In this case, although the dynamic vector detection by block matching is executed with respect to the thinned-out picture elements in the MC block, the high frequency component is cut in advance by the two-dimensional low-pass filter circuit 2 with respect to the image signal before thinning out the picture elements. In such a way, this device is not influenced by a turn-back noise by the high frequency component caused by thinning-out, uniform dynamic vectors can be obtained in each block, and an exact dynamic vector can be detected.

Filed: 1980-07-15
Abstract: PURPOSE:To obtain a battery which contains no lead iodide and lead and causes no bad effect on human bodies and environment, by combining lithium nitride used as a solid electrolyte and cuprous sulfide used as a postive active material. CONSTITUTION:A battery is constituted by the combination of a negative electrode providing lithium ions, a solid electrolyte made of lithium nitride, and a positive electrode made of cuprous sulfide used as an active material.

The grain diameters of the former lithium nitride, cuprous sulfide, and metal copper powders are preferred to be below 1,000mu, especially below 250mu. For instance, a metal mold is placed in an argon box, before a positive current collecting body, an equally smoothed positive mixture and a solid electrolyte are placed in the metal mold, in that order. After that, a negative electrode made of lithium foil is placed on the solid electrolyte, and the battery is subjected to compression molding. By the means mentioned above, a battery which has no reduction in its battery characteristics and is safe for both human bodies and environment can be obtained, since any lead iodide and lead are not used.

Title: Die cushion device of press machine
Inventor: FUJIKURA KATSUYA
IPC: B21J9/02
Filed: 1984-05-14
Abstract: PURPOSE:To enable formation of a product of which the diameter in the inside is larger by emitting a signal which turns on only in the range of the preset crank angle by a press rotary cam to provide a cushion effect. CONSTITUTION:The rotary cam detects the crank angle when an upper die enters a working area according to descending of a slide. Said cam emits the signal to a solenoid valve to turn on the valve upon such detection. The air from an air tank 6 is then supplied to a cylinder 1 which moves upward a cushion part 4 so that forming is executed under the cushion effect. The piston 2 of the die cushion cylinder 1 which is compressed and lowered is moved upward by the air pressure and a lower die ascends when the slide passes the bottom dead point and begins to ascend. The head part of the lower die inclines toward the inside in the part past the mandrel and only the product is removed. The valve 7 turns off in this stage.

Title: Transmitting device of data
Inventor: MATSUMOTO MASAHIRO
IPC: H04L7/00
Filed: 1982-06-04
Abstract: PURPOSE:To obtain a high transmission effect without using a dummy signal, by providing the titled device with a signal converter in party line transmission. CONSTITUTION:After being demodulated and synchronized automatically, the 1st signal type input signal is reproduced as a data signal having a correct waveform and prescribed phase by a reproducing circuit 8, applied to a modulator 9 and outputted to a transmission line 1 as the 2nd signal type signal modulated by the data signal. When there is no data signal in the output of a demodulator 7, the output of the modulator 9 becomes the 2nd signal type transmission wave modulated by an unmodulated signal or an invalid data signal. Since each local device 2a receives only the 2nd signal type signal from a signal converter 4, the receiving level is not changed in one local device 2a. Consequently, the local device 2a outputs always constant signal by the signal of the device 4 even if there is no data signal. Similarly, the phase of the data signal is fixed at the arrival to the local device 2a.

Title: Pellet suction collet
Inventor: URATANI TATSUYA
IPC: H01L21/52
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To prevent a pellet from cracking by dispersing impact during suction to a wide range by supporting an area near an edge of a pellet by surface contact. SOLUTION: A V-shaped recess with an opening width W1 corresponding to a width at a non-light emitting edge face 23 side of a pellet 20 is formed in a lower side of a collet 10. A groove 12 with a U-shaped cross section whose width W2 is smaller than the width W1 is put upon a recess for forming a rise up wall 11 which restricts a position of the non-light emitting edge face 23 of the pellet 20. A supporting part 13 which supports a surface near an edge 25 of the pellet 20 is thereby formed. The part of a V-shaped groove upper than a supporting part 13 becomes an escape part 14 which is not in contact with a main part of a surface of the pellet 20.  According to the above, since the supporting part 13 comes into surface contact with an area near an edge of a surface of the pellet 20 and receives impact in a wide area, even a fragile item such as the pellet 20 which is formed of III-V compound semiconductor can be handled without causing breakage and cracks.
