Title: Medium detecting device
Inventor: MIYAZAKI MASAHIRO
IPC: B65H7/14
Filed: 1991-06-04
Abstract: PURPOSE:To provide a medium detecting device which adheres dust, produced in the middle of conveyance of sheets, on the surface of a sensor protection film instead of adhesion of the duct on the outer surface of a light emitting element or a light receiving element, simply winds up the portion of the sensor protection film, to which chips are adhered, and easily prevents lowering of the output level of the light receiving element owing to adhesion of the dust. CONSTITUTION:Resin 6 is located above through-holes 9 of two coaxial conveyance guide parts located to a medium conveyance guide 7, and a light emitting element 3 is located below the through-holes and facing a light receiving element 6. A light emitting sensor protecting device 1 with which the light emitting element 3 is covered is mounted. Film holders 8A and 8B are arranged in a case 10 of the light emitting sensor protecting device 1 rotatably around a rotary shaft positioned vertically to a sheet of Fig 1. A sensor protection film 2 running through a gap between first and second case part through-holes 11 and 12, formed in the case 10, and having two ends wound around the film holders 8A and 8B causes prevention of adhesion of dust on the outer surface of the light emitting element 3.

Title: Production of optically active cyanocarnitine salt
Inventor: MORISHITA TSUYOSHI
IPC: C07C67/00
Filed: 1986-06-05
Abstract: PURPOSE:To obtain an L-cyanocarnitine salt useful for remedy and research in high purity and yield at a low cost, by carrying out effective optical resolution of a DL-cyanocarnitine salt using an optically active acid in combination with an optically inactive acid. CONSTITUTION:An L- or D-cyanocarnitine salt produced by fractional crystallization of a salt of hydroxy-DL-cyanocarnitine and an optically active acid (e.g. camphor-10-sulfonic acid) is treated with an anion exchange agent (e.g. NaOH) to obtain hydroxy-L- or D-cyanocarnitine. The product is converted to a salt of an optically inactive acid (e.g. nitric acid, perchloric acid, etc.) and the salt is subjected to fractional crystallization to obtain L-(2-hydroxy-3-cyanopropyl) trimethylammonium salt (abbreviated as L-cyanocarnitine salt).

Title: Drive method for laser diode and laser diode module
Inventor: YAMASHITA JUNICHIRO
IPC: H04B10/60
Filed: 1989-05-25
Abstract: PURPOSE:To obtain an output optical signal with low distortion by driving a laser diode approximately with a constant voltage AC signal. CONSTITUTION:A resistor 15 having a resistance Rp of the same degree as a dynamic impedance of a laser diode 1 and a constant voltage diode having the nearly equal breakdown voltage as the oscillating threshold voltage of the laser diode are connected in series and they are further connected in parallel with the laser diode 1. While the laser diode 1 is biased with an oscillating threshold current or over, a current flows to the constant voltage diode 16, but its terminal voltage is equal to the breakdown voltage, which is nearly constant, and it is equivalent that the resistor 15 is connected in parallel with the laser diode 1 in terms of AC. Thus, it is regarded as if the laser diode 1 were modulated by an AC signal source having the internal resistance nearly equal to its dynamic impedance or below and driven approximately with the constant voltage AC signal source. Thus, the laser diode is driven approximately by the constant voltage AC signal source to send an output optical signal with low distortion.

Title: Semiconductor device
Inventor: TSUJI MASUO
IPC: H03K19/0952
Filed: 1989-05-25
Abstract: PURPOSE:To reduce noise without retarding a change start time of an output MOS transistor(TR) by providing two current drive sources charging the capacitance of a control gate of the output MOS TR driving an external load. CONSTITUTION:When a charge current generating source block input 15 changes from a high level to a low level in the operation of a charge current source block with capacitance coupling, an output of an inverter 19 changes from a low level to a high level. In this case, a voltage of a control gate 4 is boosted to a high level direction depending on capacitors 17, 18 with a change in one potential of the capacitor 15 and shifted. Then the capacitor 18 is operated as if it were a temporary current source. Thus, the level is boosted rapidly to a high level by current sources 1, 2 and when the current from the current source 2 is interrupted, only the current source 1 acts like the driving source and the level changes slowly to the high level. Thus, generated noise is decreased without extending the time till the output MOS TR 3 is turned on.

Filed: 1988-05-30
Abstract: PURPOSE:To prevent generation of cooling insufficiency for rolls by positioning an opening communicating with the outside of a casing between seal members on the inside of a valve and detecting internal leakage of liquid in the opening. CONSTITUTION:In an intermediate part between a 1st seal member 25a and 2nd seal member 25b installed in a cooling liquid room 16 and a pressure room 20b, an opening 26 is positioned in a casing 11.

Abstract: PURPOSE:To prevent the inside of a manifold from being contaminated by providing such an arrangement that a fresh air shut-off valve is opened but an exhaust gas recirculating valve is closed upon fuel cut-off during deceleration even if the conditions of partial cylinder operation are satisfied. CONSTITUTION:Upon partial cylinder operation when an idle switch 24 is not actuated, that is, when the conditons of pulse width P<P1 and engine speed N> N1 are satisfied, a fuel injection shut-off circuit 25 is actuated by means of an AND circuit 22 and a seventh circuit 23 for shutting off fuel to Nos. 4 through 6 cylinders. Further, upon fuel cut-off during deceleration when engine load is low, the AND circuit 22 is turned on so that a fuel injection shut-off circuit 25 is actuated, but since an idle switch 24 is turned on due to the full close of a throttle valve and the engine speed is high so that the condition of N>N2 is satisfied, a comparator 30 and an AND circuit 31 are turned on, whereby a fuel injection parameter switching circuit 26 and a drive circuit 27 for a frech air valve and an exhaust recirculating valve are not operated. With the result of this, the adhesion of exhaust deposit to unoperated cylinders are restrained.
