Title: Inverter apparatus
Inventor: KISHIMOTO NAOKAGE
IPC: H02M7/538
Filed: 1989-11-27
Abstract: PURPOSE:To prevent first and second switching elements from being turned on at the same time by providing an inverter apparatus with a diode for letting a current flow in a second switching(SW) element via a load circuit, feedback means for turning a first SW element on/off at a prescribed period by the resonant current of the load circuit and control means for alternately turning the second and first SW elements on/off. CONSTITUTION:A transistor(Tr) Q2 to which a diode D2 is connected in inverse- parallel is connected between the base of a Tr Q1 and the negative electrode of a DC power supply E1. The detector 2c of a control circuit 2 detects the off time point of the Tr Q1 from the emitter potential of the Tr Q1 and, when the Tr Q2 is on, lets a current flow in a loop composed of the DC power supply E1, a load applying circuit 1, a diode D5 and the Tr Q2. While a load discharge light la is at the last stage of a life and the Tr Q2 is turned on even when a resonant current changes, the Tr Q1 is not turned on. Thus, the Tr's Q1 and Q2 are prevented from being turned on at the same time.

Title: Track error detecting circuit for optical disk device of sample servo system
Inventor: OZAWA YASUYUKI
IPC: G11B7/095
Filed: 1988-12-05
Abstract: PURPOSE:To surely detect a peak value by comparing the output of a peak holder with a reference potential by a comparator and switching the discharging speed of the peak holder to a lower speed at the time when the output of the peak holder is lower than the reference potential. CONSTITUTION:When several damaged wobbled pits are continuous, the output of an operational amplifier is continuously reduced and it is detected by a comparator 211 (212) that the output is lower than a reference potential Vs. A base potential E of transistors Trs Q1 and Q2 goes to the low level by the output of the comparator 211 (212), and Trs Q1 and Q2 are turned off and a current (i) is reduced. Then, the discharging speed of a capacitor C is reduced, and the fall speed of the output of the operational amplifier is reduced, and the output of the operational amplifier is not very reduced though several dam aged wobbled pits are continuously. Consequently, when a normal wobbled pit appears, the peak of a pit reproduced signal is surely detected because the capacitor C of a peak holder 201 (202) is not satisfactorily discharged, and the peak is accurately held.

Title: Manufacture of foam molded body
Inventor: SUDO YOSHIMI
IPC: B29C44/00
Filed: 1986-12-22
Abstract: PURPOSE:To obtain a foam molded body having an intricated shape with favorable formability by means of a simple forming process by a method wherein substance, which is the melt mixture of thermoplastic resin and foaming agent and which expands itself and, after that, contracts itself under the specified temperature, pressure and holding period of time, is filled in a mold, and its foaming is brought to an end in the mold. CONSTITUTION:At a process I, thermoplastic resin and foaming agent are uniformly melted and kneaded under pressure. Next, the resultant melt mixture is sent to a process II for melt mixture retaining and extruding so as to be once retained under the temperature and pressure conditions, under which no foaming develops in the mixture, and at the same time to be intermittently extruded in a low pressure zone such as atmospheric pressure zone or the like in the form of a melt mixture extrudate F and, after that, sent to a molding process III. The foaming property of the melt extrudate F is specified so that the extrudate expands itself and, after that, contracts itself when it is held at 25 deg.C and under a pressure of 1 atm for 0.5 hours. The relationship between the temperature and the amount of foaming agent in the melt mixture having the expected foaming property can be determined through simple experiments. For example, when high density polyethylene is used as the resin, the amount (x) of the foaming agent is selected with respect to the temperature (y) of the resin so as to satisfy the formula described.

Title: Magnetic head driving apparatus
Inventor: HIRAMATSU MAKOTO
IPC: G11B5/02
Filed: 1990-11-16
Abstract: PURPOSE:To shorten the inverting time of a magnetic field by providing a capacitance corresponding to the direction of a magnetic field generated by a coil current, storing electric charges while the magnetic field is zero, and supplying a current to the coil from the accumulated charges when a magnetic field is generated. CONSTITUTION:When a recording signal is '1', a switch SW1 is turned ON, an SW3 is connected to a resistance R1, while an SW5 is connected to a power source. A capacitance C1 is charged to a power voltage V. Meanwhile, an SW2 is turned OFF via an inverter 100, an SW4 and an SW6 are connected respectively to the power source and the ground. C2 is also charged to V and, 2V is added to the R1 and a coil L1, thereby generating a magnetic field+H at the coil L1. When the recording signal is changed to '0', each SW interlocks to drive C2 with 2V. A magnetic field-H is generated by the L1. Since the operation of each SW is controlled corresponding to the recording signal, even if the L of the coil is large, the rise of the coil current can be accelerated.
Patent JP-H04180129-A (JP)
Title: Interruption controller
Inventor: MIYAMOTO KEITA
IPC: G06F9/48
Filed: 1990-11-15
Abstract: PURPOSE:To inhibit the reinterruption in an interruption processing state despite occurrence of a multiple interruption by canceling a mask when a fixed time passed after an interruption mask cancel instruction is produced. CONSTITUTION:If an interruption signal is inputted to a CPU 100 when a mask control signal generating means 101 is kept in a mask cancel state, the software under execution sets a mask signal in a mask state at the start of an interruption routine and outputs the mask signal to the means 101. The means 101 receives the mask signal and outputs a signal to be set in a mask state to a control means 102 which masks the interruption signal. Then the mask signal is set in a mask cancel state at the end of the interruption routine. Thus the means 101 starts a counting operation and outputs the mask cancel signal to the means 102 after a fixed time to perform a mask canceling action. Thus a main routine can always be once reset even if a multiple interruption is produced in an interruption processing state.
