Patent JP-S61215916-A (JP)
Title: Angular velocity sensor
Inventor: HARA NAOKI
IPC: G01C19/56
Filed: 1985-03-21
Abstract: PURPOSE:To decrease an off-set voltage and to execute the correct angular velocity detection by detecting the voltage of the difference between the alternating current voltage outputted from the second piezoelectric element and the alternating current outputted from the third piezoelectric element. CONSTITUTION:Capacities 4 and 5 respectively exist among piezoelectric elements 2-1 and 2-1' for driving, piezoelectric elements 1-1 and 1-1' for detecting and piezoelectric elements 1-2 and 1-2' for non-polarization. Consequently, part of the alternating driving voltage to drive elements 2-1 and 2-1' is applied from an alternating current electric power source 3 through the capacities 4 and 5 to the elements 1-1 and 1-1' and the elements 1-2 and 1-2'. The leaking alternating current voltage goes to be an off-set voltage of the elements 1-1 and 1-1'. Though there is a little difference between the amplitude values, both go to be the same phase similar voltage waveforms. Consequently, when the difference of the voltages of the two is obtained by a detecting circuit 100, the influence of the voltage, which leaks from the electric power source 3 through a capacity 4 to the elements 1-1' and 1-1, can be decreased.

Title: Switcher for memory backup battery
Inventor: SHIMOI HIROYUKI
IPC: H02J9/06
Filed: 1990-03-12
Abstract: PURPOSE:To prevent outflow of current and to lengthen backup time of memory through a battery by providing means for preventing flow-in of battery current in series with a pull-up resistor. CONSTITUTION:When power is not fed, output at pin 3 of a voltage monitor 10 is 'Low' and a transistor Tr 3 is turned OFF, no power is fed from a power supply to a memory 8 which is fed power from a battery 9. Even if pin 3 of the voltage monitor 10 has 'High' output and a logic signal is inputted to an AND gate 17-1, the signal is not inputted as a chip select signal to the memory 8. At that time, source voltage is 0V and a voltage is applied in reverse direction from the battery 9 onto a diode D3. Consequently no current flow and power is not drained uselessly from the battery 9 but the power is entirely used in the memory 8, resulting in lengthening of memory 8 backup time through the battery 9.

IPC: H04B10/25
Filed: 1983-04-05
Abstract: PURPOSE:To enhance the stability and reduce the dimension of the titled module by adopting a co-focus lens system wherein a short focus lens is the first lens as a coupling lens system. CONSTITUTION:The semiconductor laser module has the arrangement in the order of a semiconductor laser 21, the first lens 22 which converts the light from said laser 21 into a parallel light of a diameter (d), a polarizer 23 using a double refraction material wherein the moved distance of the abnormal light is over (d), 45 deg. Faraday rotor 24, a lens 25 focusing the parallel light, an analyzer 26 whose polarizing surface inclines at approx. 45 deg. to the polarizing surface of the polarizer, and an optical fiber 27. Thereby, since the analyzer 26 is positioned after the lens 25, therefore the use of the short focus lens as the first lens 22 is enabled, and accordingly the co-focus lens system having excellent stability can be adopted. Besides, the distance between the first lens 22 and the lens 25 can be shortened, thereby inhibiting the increase of the coupling loss of the lens, enabling to thin the thickness of the analyzer. As a result, the whole of the module can be miniaturized.

Title: Pressure-sensitive adhesive sheet
Inventor: WAKATA KAZUYOSHI
IPC: B42D15/00
Filed: 1989-03-09
Abstract: PURPOSE:To prevent blocking in a perforation or a marginal part, use an electronic photography system, shoot a trouble resulting from the use on a printer, and increase adhesive power under high pressure by adding a material which becomes cured by ionized radiation to an adhesive layer and partially irradiating the material with the ionized radiation to cure it. CONSTITUTION:A pressure-sensitive adhesive sheet is constituted by adding a material which becomes cured by ionized radiation to an adhesive layer. The recommendable material which becomes cured by the ionized radiation is an optically polymerizable resin. If the resin is cured using ultraviolet ray as the ionized radiation, the adhesive layer needs a reaction initiator, and this agent is, for example, benzoinalkylether. In addition, if a material which becomes cured is used by being microcapsuled in addition to the appropriate amount of the former, it is possible to prevent the temporal deterioration of the adhesive power of an adhesive which is generated easily with the curable material. Furthermore, the partial deterioration of the adhesive power of pressure-sensitive adhesive sheet can be cured using the ionized radiation, which is a desirable phenomenon. Thus satisfactory adhesion required only when high pressure is applied is ensured.

Title: Apparatus for absorbing pulsation of liquid fuel
Inventor: MORIZAKI TAKAO
IPC: F23K5/04
Filed: 1979-05-14
Abstract: PURPOSE:To provide an apparatus capable of making an efficient use of elasticity of rubber diaphragm, absorbing pulsation of liquid fuel having a period equal to fuel discharging intervals, and attaining stable combustion of fuel, by forming the entire peripheral wall of a cylindrical fuel reserving chamber with rubber diaphragm, and forming an air chamber around the fuel reserving chamber. CONSTITUTION:Fuel forced into fuel reserving chamber 21 by the discharging pressure of electromagnetic pump 13 is not immediately discharged into fuel pipe 14a since diameter of port 5 is fairly small, but stored temperarily in chamber 21 by expanding rubber diaphragm 3 outwards. Subsequently, when discharging of fuel by electromagnetic pump 13 is stopped, fuel in chamber 21 is discharged little by little into fuel pipe 14a through small port 5 by the elastic recoil force of rubber diaphragm 3 and supplied to a burner (not shown) at a substantially constant rate. Thus, it is enabled to absorb pulsation of liquid fuel having a period equal to fuel discharging intervals of electromagnetic pump 13 and to supply fuel to the burner at a substantially constant rate, so that fuel can be combusted in stable manner.
