Title: A/d and d/a converter circuit
Inventor: SUGITA KEIZO
IPC: H03M1/00
Filed: 1985-03-15
Abstract: PURPOSE:To dissolve the difference of positive and negative polarities of a dynamic range by applying a sampled analog signal to polarity conversion, setting the polarity converting information as a code bit of a digital signal, A/D and D/A-converting the analog signal whose polarity is converted, and bringing this output to polarity reverse conversion by the code bit. CONSTITUTION:In an A/D converting circuit diagram (a), this circuit is constituted of an S/H circuit 1 for sampling and holding an analog signal which is supplied to an input terminal, a converting circuit (hereinbelow, called an encoder) 2 for applying the sampled analog signal to polarity conversion of positive or negative, and outputting its analog signal and the polarity information, and an A/D converting circuit 3 for converting an analog signal of only a position polarity, which has been outputted by this encoder 2, to a digital signal. The digital signal and a code bit are made to pass through a transmitting medium, or recorded in a recording medium. The digital signal which is picked up from said transmitting medium or recording medium, and the code bit are demodulated to the original analog signal by a D/A converting circuit shown in a figure (b). Therefore, when applying the A/D and D/A conversions, the polarity information is provided as the code bit, and the previous bit is assigned to a positive or negative signal and converted, therefore, the resolution is obtained by one bit portion more.

Inventor: KONOHARA HIROKAZU
IPC: F02M37/00
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To smoothly restart an engine after the engine has been stopped by holding the fuel pressure of an injector under the specific minimum pressure necessary for restarting when the engine is stopped in a device where the fuel in a fuel tank is forced fed to the injector by a fuel pump. SOLUTION: Whether an ignition key is turned off or not is constantly confirmed at a specified timing when an ECU 22 is switched on, and a driving signal to a fuel pump is stopped when the ignition key is off. Then the time after the switching-off of the ignition key is counted, and whether the time reaches a predetermined specified time or not, is confirmed. When the time reaches the specified time, a main power source of the ECU 22 is turned off, the ignition of engine is stopped, and the injection of an injector is stopped. Whereby the fuel pressure in the injector 20 can be kept under the specified pressure, and the engine 1 can be immediately started when the engine is to be restarted.

Title: Method for preventing abnormal expansion of capsule and capsule
Inventor: NAKAMURA HIDEKI
IPC: C04B35/645
Filed: 1983-03-28
Abstract: PURPOSE:To prevent the failure of a pressing device owing to the abnormal expansion or explosion of a capsule in the stage of compacting powder under the hydrostatic pressure of a gaseous material by opening a hole with a punching member when leakage arises in the capsule contg. the powder and the capsule begins to expand. CONSTITUTION:A heat shielding body 3 and a heater 4 of an electric heating wire or the like is placed in a pressure resistant vessel 1 having a cover body 2, and a capsule 5 which is formed of a metal, rubber, glass, etc., and contains powder 6 to be molded by compaction is placed therein. The vessel 1 is hermetically closed and while the vessel is heated with the heater 4, gas such as N2, Ar, He, or the like in a storage tank 9 is forced by a compressor 8 into the vessel and the powder 6 is molded under the pressure via the capsule 5. If there is leakage in the capsule 5 in this stage, the high pressure gas enters the inside of the capsule and the capsule expands abnormally or explodes on account of a pressure difference in the stage of reducing the pressure, thus breaking the heater and others. The top end plate 13 of the capsule 5 is thinly formed to allow this part to expand first and holes are punched by punching members installed at a space C, by which the internal pressure of the capsule is quickly reduced and the abnormal expansion and explosion of the capsule 5 are prevented.

Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of the reading/writing performance of hardware by controlling the file arrangement of video data through the use of control information in a control file to increase a data size which can be accessed simultaneously. SOLUTION: When a command received from a terminal 112 is a video- recording command, video data obtained by a video data input/output device 108 through a video data signal line 110 is written in a main storage 103. At the time of newly video-recording video data in a disk, an MPU 101 controls a disk controller 106 to designate an unused address concerning video data in the main storage 103 to write into a disk 107. In this case, whether an unused cluster exists or not in its using situation is investigated in an order from the top of clusters by referring to a cluster control table when it exists, data is written in the address. Consequently, video data is handled as a file controlled as an OS controller 105 and the arrangement of video data can be controlled.

Title: Liquid detector
Inventor: WATANABE MAKOTO
IPC: G01F23/26
Filed: 1994-02-25
Abstract: PURPOSE:To widen the application range of liquid detector by detecting the capacitance being set by a liquid present between a pair of opposing electrodes and comparing the detected value with a reference value thereby determining presence of liquid in a pipe easily. CONSTITUTION:A pair of electrodes 2, 3 of copper plate, for example, are embedded oppositely to a pipe made of rubber or synthetic resin thus connecting a series/parallel resonance circuit 7 with a reference sine wave oscillation circuit 8 connected therewith. A positive pole side detecting circuit 9 is connected with the output terminal of the circuit 8 and a negative pole side detecting circuit 11 is connected with the output terminal of the circuit 7. When water is not present in a pipe, capacitance between the electrodes 2, 3 is very low and the negative voltage from the circuit 7 is lower than the positive voltage from the circuit 8 and when the sum of voltages is compared 14 with a reference voltage, an H level control signal is outputted to actuate an alarm means 20. When water is present in the pipe, the capacitance increases steeply to cause series resonance of the circuit 7 and an AC current flows from the circuit 8 to the circuit 7 thus notifying the presence of water.
