Title: Engine starting device
Inventor: KOIKE YUKINAGA
IPC: F02N11/08
Filed: 1996-03-25
Abstract: PURPOSE: To provide an engine starting device with an engine starting detecting means capable of reducing erroneous detection of engine starting and improving detecting reliability. CONSTITUTION: The engine starting detecting means of an engine starting device comprises a capacitor C1 to hold the first partial pressure valve C of a battery voltage A right before a self-starting motor is driven through OFF of a switching element Q1 during a specified period; and a comparator U1 to feed a holding value, held by the capacitor C1 within the specified period and the secondary partial pressure D of the battery voltage A, and decide that the second partial pressure D exceeds the holding value. When it is discriminated by the comparator U1 that the second partial pressure D exceeds a holding value, it is decided that the battery voltage A exceeds a value before the starting of the self-starting motor, and it is detected that an engine effects complete explosion and effects starting.

Filed: 1994-03-14
Abstract: PURPOSE: To prepare a reaction medium suited for a polymerization reaction by incorporating a high concentration of a specified monomer in a polyphosphoric acid of a relatively low phosphorus pentoxide content.  
     CONSTITUTION: A liquid-crystalline polymer composition is produced by carrying out the polymerization while keeping the phosphorus pentoxide content corresponding at a value within the shaded region surrounded by ABCDEFGHI on the graph in Fig., whereby the polymerization can be practiced under conditions to exercise the molecular weight control by adding a monofunctional reactant, by deviating the ratio among monomers from the stoichiometric one or by terminating the polymerization. In a process for producing a liquid-crystalline polymer composition, the polyphosphoric acid after the reaction contains 82-86 wt.% P 2 O 5 , and 0.025-3 mol.% of the reactants in the mixture is the specified monofunctional reactant.

Title: Molding having fluorinated surface
Inventor: MAEDA KAZUHIKO
IPC: C07C49/167
Filed: 1991-04-01
Abstract: PURPOSE:To modify the surface of a hydrocarbon polymer molding by fluorination without detriment to the properties of the base.

Title: Recorder
Inventor: OOKUBO HIROTSUGU
IPC: G11B23/30
Filed: 1997-03-21
Abstract: PROBLEM TO BE SOLVED: To prevent an important record from being erroneosuly erased by providing a recording inhibiting section and stopping recording operation upon reaching the inhibiting section during recording. SOLUTION: Count values of the first and the last position of a desired arbitrary section for recording inhibition of a tape cassette 1 are specified by operating keys 16, and information of this specified section is stored in a memory 6 from a microcomputer 15. Then, when a tape traveling amt. count value by a counter 19 of the cassette 1 falls within the inhibiting section, recording is inhibited. That is, when the cassette is loaded into a deck to sart recording, if a count value at this time falls outside the inhibiting section read out of the memory 6, recording is started up. However, even after this recording is once started, a count value of the counter 19 and the inhibiting section read out of the memory 6 are collated with each other to detect whether the count value falls within the inhibiting section or not.  Then, at the time of nonarrival in the inhibiting section, the recording is continued, and at the time of showing the inhibiting section by the count value, the recording is finished at once.

Title: Magnetic resonance imaging device
Inventor: OKANE MASAKO
IPC: G01R33/28
Filed: 1986-03-28
Abstract: PURPOSE:To simplify a processing by optionally designating and displaying an object part. CONSTITUTION:Conventionally, a center frequency and a center phase are fixed and cannot be optically changed, however, they can be changed by an external designation. Namely, the frequency f0' different from the conventional center frequency f0 is designated when extracting data after a high speed Fourier transformation processing in a picture reconstitution processing, thereby, the data of the range of 2DELTAf centering the f0' is stored in a magnetic disk. This is similar in a phase encoding direction. Not only the center frequency and the center phase can be changed but also the size in an extracting area can be optionally changed.

Title: Treatment of steel plate applied with primary rust preventive paint prior to welding
Inventor: SHIMATANI SHIROU
IPC: B23K31/02
Filed: 1982-04-26
Abstract: PURPOSE:To prevent the generation of any welding defect such as blowhole, by heating the rust preventive paint film on the surface of a steel plate applied with primary rust preventive paint thereby removing the volatile matter therefrom prior to welding of said steel plate. CONSTITUTION:The heating of the rust preventive paint film on the surface of a steel plate prior to welding may be usually at about 40-500 deg.C because the thickness of the paint film is generally of about 10-30 microns. A gas burner, IR light, hot wind or the like is used as a heating means to heat the paint film surface forcibly. The volatile matter (moisture and solvent) in the paint film is thus thoroughly removed and the generation of any blowhole, etc. in the stage of welding is easily prevented.

IPC: C23F4/00
Filed: 1988-03-25
Abstract: PURPOSE:To carry out etching with low damage, high selectivity, and high anisotropy by blowing out a Cl2-containing reactant gas through a high-temp. nozzle into vacuum, applying this reactant gas in the form of a beam to a substrate, and also maintaining the temp. of the substrate at a specific value or below. CONSTITUTION:In a reaction vessel 1 capable of evacuation, a substrate 3 of Si, etc., is placed on a substrate-supporting body 2 capable of temp. control by means of a heater 11. A graphite nozzle 4 enclosed by a quartz tube 10, a heater 6, quartz tubes 7, 8, etc., is provided above the substrate 3 in a manner to be opposed to the substrate 3. This nozzle 4 is heated up to about 700-900 deg.C by means of the above W-wire heater 6.

Title: Phase synchromizing circuit
Inventor: TSUKAMOTO JIYUNICHIROU
IPC: H02M7/48
Filed: 1981-05-06
Abstract: PURPOSE:To speed resynchronization after a synchronous power source is turned off, by constituting two phase synchronous loops by using two filters differing in time constant for the same voltage-controlled oscillator. CONSTITUTION:A phase synchronizing circuit which has two loops consists of phase difference detectors 2 and 21, filter circuits 3 and 31, an adder 7, a V/F converter 4, and a frequency divider 6. The filter 31 has a small time constant for the filter 3. The output of a synchronous power source 1 is applied to the phase difference detectors 2 and 21 and when synchronization is attained, the 1st output 8 of the frequency divider 6 is applied to the phase difference detector 2 to obtain a constant phase difference from the synchronous power source 1 while the 2nd output 9 is applied to the phase difference detector 21 to obtain phase coincidence with the synchronous power source 1. Since the time constant of the filter 31 is small, resynchronization is speeded if an out- of-synchronism state is caused by the instantaneous break of the synchronous power source.

Title: Flow rate control in electric power station using water from dam
Inventor: UMEZAWA SOHEI
IPC: F03B15/02
Filed: 1986-03-27
Abstract: PURPOSE:To derive an output from a hydraulic turbine effectively, by determining the limit of flow rate of the water to be flown into a turbine water conductor based on whether a guide vane is at its maximum opening or the output of the water turbine is at its limit value. CONSTITUTION:A designated quantity of water stored in a dam 1 is discharge downstream and its flow rate is controlled so that a flow rate exceeding the output limit of a water turbine 4 is not introduced into a turbine water conductor 2a. Whether the flow rate corresponds to a set value or not is determined based on whether a guide vane 5 is at its maximum opening or the output of the water turbine 4 is at its limit value for flow control. With this arrangement, an output from the water turbine can be derived most efficiently at the designated discharge quantity at a time.
