Title: Video signal recording device
Inventor: MATSUMURA OSAMU
IPC: H04N5/782
Filed: 1990-11-26
Abstract: PURPOSE:To correctly perform mutual adjustments between plural channel and to correctly adjust distortion of the recording system by providing a gradation reference signal insertion circuit. CONSTITUTION:A reference signal generation circuit 8 generates a synchronizing signal SYNC, a burst signal BURST and an identifying signal ID as well as a gradation reference signal REF at a prescribed timing and inputs them to signal adding circuits 9 and 15. As it can be seen from the above, a use if made of the reference signal which varies gradually and continues the same level signal. Therefore, even though there be a deviation in a sampling timing, the same level reference signals prior to or right after the sampling timing are recorded and reproduced. Thus, even though a jitter is generated, mutual adjustments between plural channel are correctly performed and the adjustment at the reproduction system against the recording system is correctly done as well.

Title: Receiver
Inventor: MASUDA MITSURU
IPC: H04B1/16
Filed: 1988-12-21
Abstract: PURPOSE:To improve the degree of freedom in the selection of an intermediate frequency and to share the constitution of an intermediate frequency part by selecting either plural low-pass filters with different cutoff frequencies corresponding to the frequency of an input signal. CONSTITUTION:A signal A1 inputted to an input terminal 1 passes a high-pass filter 2, and passes a low-pass filter group 3 in which a first low-pass filter 3A is connected in series to a second low-pass filter 3B, and is selected at a switch 4 corresponding to an input frequency. After that, it is frequency- converted to the intermediate frequency A3 by the output signal A2 of a frequency synthesizer 6 at a frequency converter 5, and is outputted from an output terminal 7. In such a way, it is possible to decrease the lower limit frequency of the intermediate frequency, and to extend the degree of freedom in the selection of the intermediate frequency by relaxing the limitation of the intermediate frequency, and to share the constitution of each intermediate frequency by setting the intermediate frequencies of receivers having different input frequency band areas equally.

Title: Alkaline battery
Inventor: UEMURA TOYOHIDE
IPC: H01M4/42
Filed: 1990-11-28
Abstract: PURPOSE:To restrain hydrogen gas generation and still improve battery performance by adding a preset amount of alkaline metal or alkaline earth metal hydroxide to negative electrode material which is mde of reactive zinc alloy power and electrolyte. CONSTITUTION:1-10 pts.wt. alkaline metal or alkaline earth metal hydroxide to 100 pts.wt. zinc alloy powder is added to negative electrode material which is made of reactive zinc alloy power and electrolyte. If the ratio of addition is less than 1 pt.wt., both discharge property and hydrogen gas generation property can not be effectively improved. On the other hand, if the ratio of addition is over 10 pts.wt., other negative electrode material which is to be filled into a preset volume of a battery is reduced in quantity, to preclude discharge property in particular from being more effectively improved than usual. It is thus possible to greatly restrain hydrogen gas generation in a battery and still improve battery performance in spite that reactive zinc alloy powder is used as negative electrode active material.

Title: Molding sand regenerative method
Inventor: MASUNO OSAMU
IPC: B22C5/02
Filed: 1992-11-06
Abstract: PURPOSE:To reduce the crushing of the molding sand itself, and to realize the rapid regeneration treatment by executing the throwing at high speed in the beginning of the regeneration treatment when the layer of impurities of the molding sand to be regenerated is thick, and reducing the speed successively. CONSTITUTION:The molding sand to be regenerated is supplied from a sand supplying valve 11 to a treatment tank 1. The sand stored in a coned part 2 is elevated through a sand-blowing pipe 26 by the compressed air blown out of a nozzle 5, and supplied into a rotor 16. The sand thrown out by the centrifugal force due to the rotation of the rotor 16 is collided with the sand layer deposited on a sand-receiving shelf 22, and the impurities on the sand surface is separated by the grinding between the sand. The separated impurities are sucked by a discharging cylinder 12. Even when the rotor 16 is set to a relatively high speed in the beginning of the treatment where the thickness of the impurities is still thick, the crushing of the sand itself is small due to the cushioning effect of the impurities. As the treatment is proceeded, the layer of the impurities becomes thinner, and the rotation of the rotor 16 is reduced to a relatively low speed and the crushing of the sand itself is prevented.

Title: Power interruption monitoring system
Inventor: OZAWA MASAHIRO
IPC: G06F1/28
Filed: 1988-12-23
Abstract: PURPOSE:To attain the interruption of the power supply of a system with high efficiency by checking previously and individually the interruption time of a device to be interrupted at initialization and registering the data on the interruption time. CONSTITUTION:A writing means 6 receives an instruction signal, i.e., a memory request of the clocking data and writes a first clocking data received from a clocking means 3 into an area for the 1st device interruption waiting time of a waiting time memory means 5. An interruption instruction means 2 receives a power interruption instruction request signal for a 2nd device 1b, i.e., the next device to be interrupted of a 1st device 1a of a device 1 to be interrupted from an interruption end detecting means. Thus the means 2 outputs a power interruption instruction signal to the device 1b and repeats the same action. Thus all devices to be interrupted can be processed. As a result, the interruption end waiting state can be individually monitored as necessary even though the long and short power interruption action times are included in the same system.
