Title: Pdm signal decoding circuit
Inventor: TAKESHITA KENICHIRO
IPC: G11B20/14
Filed: 1987-12-08
Abstract: PURPOSE:To simplify a constitution by forming plural windows corresponding to logical values '1' and '0' based on a mobile clock and detecting a timing when the level change of a PDM signal occurs. CONSTITUTION:The title circuit has a means to count a mobile clock with the starting timing of a PDM (Phase Duration Modulation) signal as a reference, to forecast respectively the period when the level change occurs concerning logical values '1' and '0' on the way of one period of the PDM signal based on the counted value and form a window and a means to detect at which window the level change of the PDM signal exists, judge the logical value of the PDM signal and output the decoding value. Consequently, in order to form the window, a clock synchronized correctly to the PDM signal is not necessary, the mobile clock is sufficient, and therefore, the PLL circuit is also unnecessary. A multi-vibrator, etc., are unnecessary and the whole can be digitized. Thus, the constitution can be simplified.

Title: Production of fiber-reinforced resin helmet
Inventor: KONO MASARU
IPC: B29L31/48
Filed: 1993-12-10
Abstract: PURPOSE:To prevent stay of a resin from occurring by a method wherein using a mold vertically divided into right and left molds, unreacted material liquid is injected into a cavity through a film gate provided along a top part of a helmet to be molded and front and back parting faces connected to the top part. CONSTITUTION:With the application of a secondary pressure to a flexible sheet 31, the cavity space is pressurized from the part of a film gate 28 with a smaller distance to the flexible sheet. The cavity space is successively pressurized toward the openings on the ends of the right and left molds each provided with a discharge port 30. In the part with the small distance to the flexible sheet, the expanded flexible sheet 31 immediately abuts against a reinforcing fiber 12 previously disposed and cannot expand, and the pressure is increased. In a part near the discharge ports 30 with a large distance from the flexible sheet, the flexible sheet 31 does not immediately abut against the reinforcing resin 12, and a pressure increase is delayed. In this manner, the pressurizing speed is lowered in the direction of successively increasing distance from the part of the film gate 28 to the outlets, whereby a stay of the resin can be prevented.

Title: Overcurrent protective circuit
Inventor: INOUE YUICHI
IPC: H04B1/18
Filed: 1990-11-15
Abstract: PURPOSE:To cut off the current supply to the load when a device gets in an over-current condition and an over current is detected and to resume the current supply automatically after elimination of the cause of the over current by making up the device from an oscillation circuit, a circuit to detect an over current and a flip-flop circuit. CONSTITUTION:In the case that a current is less than a rated value, a transistor Q1 is in an OFF condition and a transistor Q2 in an OFF condition. When an over current flows in the load, the transistor Q1 is switched ON by a voltage drop in a resistor R1 with a 'd' point at the 'L' level and an 'e' point at the 'H' level. Then, the transistor Q2 turns OFF followed by the cutoff of the current supply to the load. When the resistor Q1 turns OFF, the 'd' point comes to the 'H' level, however, the 'e' point is held at the 'H' level until the 'L' level pulse is applied to a 'c' point. With the 'L' level pulse applied to the 'c' point from an IC 1 for a timer, the 'e' point changes to the 'L' level and the transistor Q2 turns ON and finally the current supply to the load is resumed.

Filed: 1994-12-15
Abstract: PURPOSE: To effectively utilize the hardware resources and line resources of a communication system which uses plural lines by distinctively using respective queuing processes for telephone numbers, transmission, and busy states. CONSTITUTION: A communication control unit 30 inputs monitor data from a remote monitor and control equipment by modems SP24-1-SP24-q through a pay telephone line, and sends control data out by the SP22-1-SP22-p. When control data is received from an unillustrated control display terminal, it is decided whether the telephone number as part of the data is registered in a telephone number table 31 and when the telephone number is registered, a queuing process is performed for number queues q1-qN in the table 31. When not, it is registered and a queuing process is performed. Further, free communication lines are searched for in order and a free line is connected to perform the transmission queuing process for the data of the number table.  When transmission is completed within a specific time, the number is deleted from the number table, but when the transmission is not completed, the busy queuing process is performed. When there is not queuing, a wait state is entered. Free lines are searched for and the function is constituted with a small number of lines, so the cost performance is superior.

Title: Electrophotographic sensitive body
Inventor: HANATANI YASUYUKI
IPC: G03G5/05
Filed: 1991-11-26
Abstract: PURPOSE:To provide a photosensitive body having improved stability against light and ozone and high sensitivity by forming a photosensitive layer containing a specific stabilizing agent. CONSTITUTION:A photosensitive layer containing at least one kind of salts expressed respectively by formulas I, II, III as a stabilizing agent is formed on a conductive base body. In the formulas, R<1>-R<4> may be the same or different and represent hydrogen atom, alkyl group, aryl group, aralkyl group and X an anion. Each of the salts expressed by the formulas causes a chain reaction due to an active singlet state oxygen or oxygen in a ground state which acts as an oxidizer and thus an electric charge generating material is prevented from being deteriorated. Consequently, in the case where especially an azo compound or a perylene compound is used as an electric charge generating material for a photosensitive body, the decrease of surfacial potential of the photosensitive body can be prevented even if it is used repeatedly and it is possible to stably keep high sensitivity against exposure for a long period and exposure under high temperature.

IPC: G11B7/30
Filed: 1989-11-30
Abstract: PURPOSE:To obtain a uniform state of initial crystallization over the whole recording layer by irradiating the information recording medium with a beam for initial crystallization in a manner that the irradiation power of the beam differs for the outer circumferential area and for the center area of the medium. CONSTITUTION:Laser light from a semiconductor laser source 13 is changed into a parallel beam by a collimator lens 14, directed to enter an objective lens 16 by a beam splitter 15, and focused on a recording layer of a disk substrate 10. A position detector 17 detects the position of the optical unit 12 and sends signals according to the detected position to a controller 18. The controller 18 controls output of the semiconductor laser source 3 according to the input signal from the detector, for example, the output of the laser light gradually increases from the center part of the disk substrate to the outer circumference. By this method, the recording layer of the disk substrate can be uniformly irradiated with the beam in a constant energy density. Thus, the whole recording layer can be initially crystallized at the same level.

Title: Liquid amount detecting device
Inventor: KINOSHITA TAKESHI
IPC: G01F23/22
Filed: 1987-12-11
Abstract: PURPOSE:To obtain the inexpensive device of a simple structure which is rich in mass- productivity by feeding electricity to a heater for a certain time according to the amount in the liquid in a hot water reservoir container and detecting and deciding a charging time difference generated between a temperature-dependent resistor and a capacitor after the temperature of the reservoired hot temperature reaches specific temperature and the power source is turned off. CONSTITUTION:A transistor (Tr) 2 is turned on for the certain time to turn on a switching circuit SW and thus the heater 3 is powered on to hold the hot water in the hot water reservoir container 2 at constant temperature; and then the Tr 1 is turned off and the circuit SW is turned off to cut off the power supply to the heater. At the same time, a transistor Tr 1 is turned off and then a DC power source VCC begins to charge the capacitor through the resistor 1 with the time constant based upon the resistance value of the temperature-dependent resistor 1 and the capacity value of the capacitor C. When its charging voltage reaches the reference voltage of a comparator Com, the Tr 1 is turned on to discharge the capacitor. Its OFF time at this time and the charging time after a preset time are counted by a counter to decide the quantity of variation.
