Title: Image storing device having frame thinning function
Inventor: NINOMIYA MASAKO
IPC: H04N19/00
Filed: 1994-04-06
Abstract: PURPOSE:To provide an image storing device having a frame thinning function for reducing the stored amount of images by extracting images only when an object to be photographed is moved and storing them. CONSTITUTION:An image 1 changing with the lapse of time is photographed by a camera 2 and inputted. When the movement of an object to be photographed is detected by a sensor 3, an image storing device 4 extracts images inputted through the camera 2 and stores them. On television 5 images stored in the image storing device 4 are displayed and confirmed. By extracting and storing images in a memory only when the object movement is detected by the sensor 3, the amount of storing images when the object is not moved for a long time is reduced and thus an inexpensive image storing device capable of effectively utilizing an image storing medium is provided.

Abstract: PURPOSE:To enhance the color repeatability and to solve the difficulty of adjustment and the unstableness of a reference level in case of a PAL system by summing up orthogonally intersecting modulation axis signals and by making the addtion signal into a modulation signal. CONSTITUTION:A modulation carrier signal 2-14 is added to a signal inverted by an inversion amplifier 6-2 through a variable resistance 6-1 and an original signal through a resistance 6-11. An added R-Y carrier signal is added by a modulation carrier 2-15 orthogonally intersecting with an R-Y modulation axis and resistances 6-3 and 6-4, turns out to be a B-Y modulation signal 6-9 and modulates a color difference signal B-YL by means of a balance modulator 2-17. In a simular manner a modulation signal 6-10 becoming a modulation carrier signal of a balance modulator 2-16 is obtained in such a way that the modulation carrier signal 2-14 is added to a B-Y carrier signal obtained by adding an original signal through a resistance 6-12 of a modulation carrier signal 2-15 to a signal which is inverted by an inversion amplifier 6-8 and whose amplitude is made variable by a variable resistance 6-7. A chrominance signal can be obtained by modulating with the aid of said modulation signal.

IPC: H01C7/10
Filed: 1990-03-19
Abstract: PURPOSE:To stably obtain a voltage non-linearity resistive element with a high non-linearity by using a low-priced NiO as a metallic oxide layer. CONSTITUTION:Nickel(Ni) is formed as a first electrode layer 2 by about 0.5mum thick on a glass substrate 1 by vapor deposition. Then, an oxide layer 3 composed of ZnO layer or a layer mainly consisting of ZnO is formed by about 1.0mum thick by a sputtering process with ZnO sintered body as a target. Subsequently, a metallic oxide layer 4 composed of NiO layer or a layer mainly consisting of NiO is similary formed by about 1.0mum thick with NiO sintered body as a target. Aluminum(Al) is formed as a second electrode layer 5 by about 0.5mum thick on this metallic oxide layer 4 by vapor deposition. When voltage is applied in the normal direction to the first and second electrode layers 2 and 5, electric current begins to abruptly flow through a potential barrier 3a if the barrier exceeds a certain voltage 50 that an asymmetrical voltage non-linearity is shown. Thus, it is possible to stably obtain a varistor with a high non-linearity.

Title: Manufacture of functionally gradient material
Inventor: KUWABARA MITSUO
IPC: B32B15/04
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of cracks or deformations positively at the laminated place by controlling a ratio of thermal expansion between a ceramic composition part and a metal composition part to be specific %, and effecting simultaneous calcination in a laminated state of the ceramic side material and metal side material set in this manner. SOLUTION: Each thermal expansion coefficient of a ceramics composition part and a metallic composition part is substantially the same during the calcination period, i.e., at a temperature of the manufacture, and set to be the same at a temperature of the use. In this manner, separation or the like in the lamination place can be precluded effectively. Herein, the thermal expansion coefficient uses a combination of W-Cu and MoCu as a metal side composition to be controlled by changing each composition ratio; on the other hand, as a ceramics side composition, metallic aluminum, aluminum nitride and other additives are controlled by changing each composition ratio. Thus, selection is done to be a thermal expansion coefficient of the ceramics composition part/a thermal expansion coefficient of the metallic composition part × 100=75-125%.

The location of the portion of conductive surface film 2 is detected by the change of the electric signal and a detected signal supplying section 11 supplies a location signal to an electrode terminal-connecting mechanism section 3. The portion of conductive surface film 2 is thus surely detected.

CONSTITUTION:A heat-shrinkable tube has a double-layer structure consisting of an inner layer part 1 and the outer layer part 2 laminated thereto, and the inner layer part 1 is constituted of a composition prepared by compounding 0.1-5 pts.wt. of an anti-rust agent with 100 pts.wt. of a thermoplastic resin. As the anti-rust agent, there are a BTA derivative such as benzotriazole(BTA) or methyl BTA, tolutriazole, 2-mercaptobenzothiazole or the like; one or more kind of them is used. Compositions are simultaneously extruded by a double-layer extruder to prepare the tube having the double-layer structure and said tube is irradiated with electron beam to be crosslinked and expanded at a magnification of about two times in the diameter direction to be subsequently cooled. Since the heat-shrinkable tube has the double-layer structure and the inner layer part is constituted of a thermoplastic resin containing the anti-rust agent, when said tube is used in the insulating treatment of the junction of a cable, a copper conductor is not discolored.

Title: Controller for inverter
Inventor: SAWA KUNIHIKO
IPC: H02M7/537
Filed: 1978-06-08
Abstract: PURPOSE: To block overcurrent and improve current waveform by conducting voltage control while conducting pulse-width modulation of the inverter output voltage under current instantaneous-value control.  
     CONSTITUTION: There are provided a comparator 7 which compares the current set point I* generated by an inverter output voltage adjuster 3 with the actual inverter current value I; a pulse allotter 8 which generates a selection signal having an electrical angle width for selectively and sequentially making transistors conductive; and gate circuits 91∼93 which are open-close controlled by the output signal of the comparator 7 and enable blocking of transmission of the selection signal. Each time when the actual current value I has reached an upper limit set point I*+Δ, the comparator 7 closes the gates 91∼93 for blocking the transmission of the selection signal, thereby turning off the conducting transistors Tx∼Tz and reducing the current I. By this consitution the inverter output current becomes trapezoidal in waveform, the magnitude of which is limited to the level of the current set point  from the voltage adjuster and kept within the ripple width determined by the  hysteresis width of the comparator 7.

Abstract: PURPOSE: To improve the ignition performance of a rotary evaporation type device, by making the area of the opening of the part of a pressure equalizing plate opposed to an ignition electrode, smaller than that of the other part.  
     CONSTITUTION: A head body 26, a pressure equalizing plate 27, a plurality of overlapped porous flame port plates and a keep plate 29 are overlapped and coupled together so that a burner head 25 is formed.
