Title: Multibeam scanning optical device
Inventor: IMAMICHI KAZUYUKI
IPC: G02B26/10
Filed: 1994-07-13
Abstract: PURPOSE:To correct the curvature of a scanning line well and to obtain a synthetic picture having good quality by making a light beam transmitted through a beam separating means incident on a deflecting surface of an optical deflector inside a surface perpendicular to a main scanning surface from an inclined direction. CONSTITUTION:A semiconductor laser 1a is arranged in a state where it is deviated by a specified amount from the optical axis of a collimator lens 2a in order that the light beam outgoing from the laser 1a is made incident on the deflecting surface 5a of an optical deflector 5 at an angle theta from the inclined direction inside the surface(subscanning surface) perpendicular to the main scanning surface. Thus, a reflection point on the deflecting surface 5a is deviated up and down in accordance with the rotation of the optical deflector 5; as a result, the curvature is caused on the scanning line of the light beam on the surface of a photodetector 9. The incident angle theta of the light beam made incident on the deflecting surface 5a is set in a state where the curvature amount of the scanning line at this time is nearly the same as that of the light beam caused in the case the light beam is transmitted through a dichroic mirror 7 for separation, and only the direction of curvature is different, so that the curvature is reversely corrected. Thus, the scanning line on the surface of the photodetector 9 is in a straight line condition without having the curvature.

Title: Dc type gas discharge display device
Inventor: SASAKI KENSUKE
IPC: H01J17/49
Filed: 1996-07-15
Abstract: PROBLEM TO BE SOLVED: To raise the current value of an auxiliary cell having a lowered resistance value by setting a second space between a discharge auxiliary positive electrode and a second connecting electrode on a wiring insulating layer narrower than a first space between the discharge positive electrode and a first connecting electrode. SOLUTION: In order to reduce the resistance value of an auxiliary cell smaller than the resistance value of a display cell, the extending directional sizes of a second connecting electrode part 43 and a discharge auxiliary positive electrode 35 on a wiring insulating layer 31 are optionally and suitably increased only in such a direction that the space between the both is narrower than the space D between the second connecting electrode part 43 and a discharge auxiliary positive electrode 33. In this example, the sizes of both the second connecting electrode 43 and the discharge auxiliary positive electrode 35 are increased in the extending direction, but the size of either one of them may be increased. Consequently, the distance H becomes shorter than the distance D, and the current limiting effect of the resistance is minimized.  Namely, the resistance value within the auxiliary cell is minimized. Thus, a sufficient auxiliary current can be carried to the auxiliary cell.

Title: Control valve apparatus
Inventor: MUTOU YOSHITAKA
IPC: F15B11/08
Filed: 1982-10-21
Abstract: PURPOSE:To facilitate installation and reduce the pressure loss by directly housing a check valve in a spool of a spool control valve apparatus having an orifice. CONSTITUTION:A check valve 46 is provided to a communicating passage 45 formed by making the interior of a spool 17 hollow to allow a flow only from an orifice 44 to the side of a chamber 23. The area b of the chamber 23 side is made small in comparison with the pressuized area a of the seat side, and the orifice 44 and an upper communicating hole 41 are communicated at all the time. The pressure in a rod side chamber 51 is increased due to the movement of a cylinder to push open the check valve 46, allowing the return oil to join in the second annular groove 39 through a communicating hole 42 to cause the pressure in the chamber 23 and the seat side of the check valve 46 to become equal, but due to the differential pressurized area a>b, the check valve 46 is held in its opened position. When the communicating hole 41 is communicated to the first annular groove 38, as an outside port 48 is communicated to a tank 66 through the communicating passage 45 to become the tank pressure, the check valve 46 is returned to the closed position by the force of a return spring 71 to interrupt the communication between the outside port 48 and the second annular groove 39.

Abstract: PURPOSE:To improve a group delay time characteristic by connecting plural stages of helical resonant elements through capacity elements for interstage coupling, and providing an indirect coupled circuit for attenuation pole formation, and at the same time, providing a coupled circuit for phase compensation. CONSTITUTION:In a polarized band-pass filter, the signal of attenuation area, which is transmitted from a branch junction point P1 through a main circuit, consisting of the helical resonant elements R2-R5, and arrives at the branch junction point P6, leads in its phase by 90 deg., and the signal of the attenuation area, which reaches the junction point P6 from the junction point P1 through the indirect coupled circuit for attenuation pole formation, consisting of induction element L16, is delayed in its phase by 90 deg.. Then, because the phase difference of 180 deg. is generated between both signals, by adjusting the degree of coupling of the indirect coupled circuit for attenuation pole formation and the main circuit, the amplitudes of both signals are formed so as to be equal to each other. Next, by selecting the capacities of capacity elements C25 and C52 to form an indirect coupled circuit for phase compensation and the induction of the inductance element L25, a phase characteristic in a passing band is linearized.

Title: Overrun preventer of positive crankcase ventilation type diesel engine
Inventor: SHIRAISHI YASUNORI
IPC: F02D9/02
Filed: 1991-06-28
Abstract: PURPOSE:To stop an engine so smoothly when the engine tries to overrun due to an increment of blow-by gas quantity, in reference to an overrun preventer of a positive crank-case ventilation type diesel engine. CONSTITUTION:A speed detector 12 is adjoined to a turning shaft 11 of an engine E, and an on-off valve 4 is installed in an intake passage 1. This speed detector 12 is interlocked with a valve driving means 5 of the on-off valve 4, and when the detected engine speed N of the speed detector 12 becomes more than the setting speed NO, the on-off valve 4 is closed by operation of the valve driving means 5 whereby the intake passage 2 is constituted so as to be interrupted. When a blow-by gas quantity turning to fuel replacement is markedly increased due to wear and damage to a piston ring and the diesel engine E tries to overrun, an overspeed state in the tuning shaft 11 of the engine E is detected by the detector 12, and since the on-off valve 4 intercepts the intake passage 1, the diesel engine E is stopped at once, thus any possible overrun is prevented from occurring.
