Patent JP-S62211843-A (JP)
Title: Camera tube
Inventor: KATO SHINICHI
IPC: H01J31/38
Filed: 1986-03-12
Abstract: PURPOSE:To keep of any drop in image quality due to dielectric breakdown, by installing a shallow groove, in proportion to a faceplate, on a glass surface lying between a faceplate back outer circumferential part and a faceplate back inner part, and raising up the extent of creeping dielectric strength. CONSTITUTION:A groove 9 is installed between a transparent conductive film 2, a photoconductive film 3 and indium 6 on a glass surface of the backside of a faceplate 1. With this, length running along the faceplate glass surface between the transparent conductive film 2, the photoconductive film 3 and the indium 6 is considerably extended longer. If depth of this groove 9 is deepened, a creeping distance is prolonged. However, if it is deepened too much or a corner form of the groove 9 is made into such one as being small in a radius of curvature, mechanical strength in the faceplate 1 has been lowered. Accordingly, it is desirable to be in a form as the groove 9 shown or so shown in illustration. With this constitution, tube discharge is hard to occur, thus a favorable regenerated image is securable.

Filed: 1993-03-12
Abstract: PURPOSE:To restrain reversible reaction at the time of charge/discharge from being degraded, and thereby lengthen the life of the battery by filling gel of gas permeability into the circumference of each electrode group, and thereby enabling electrolytes to be fed to each electrode. CONSTITUTION:Electrode groups 4 are housed in the container 2 of the secondary battery, so that a single cell is thereby formed. A gelling agent is filled up in the cavity section 3 at both the sides of the electrode groups 4. After that, a KOH electrolyte is adjusted in liquid measure so as to be added, the gelling agent is made to hold the KOH electrolyte so as to be swelled out, so that gel 1 is tightly closed with a cover 5, and a pressure regulating valve 6 is installed on the cover 5. By this constitution, a great amount of the electrolyte is held so as to allow the electrolyte to be fed to electrodes, and concurrently the decreasing rate of the electrolyte within the electrodes can be restrained from being degraded when charge/discharge is repeated.

Title: Stencil printing press
Inventor: OHINATA KICHIJI
IPC: B41L13/16
Filed: 1990-03-06
Abstract: PURPOSE:To prevent the occurrence of density irregularities in a printed matter by a method wherein a gear mechanism allows an inner pressing roll to be pressed against the inner circumferential surface of a peripheral wall by the rotating force of a plate cylinder. CONSTITUTION:When a paper switch 16 detects the feeding of printing paper 12, an inner pressing roll 19 shakes downward to abut on the inner circumferential surface of a peripheral wall 4 to be depressed down against a rear pressing roll 10. When a plate cylinder 2 and a drive gear 34 are driven to rotate in a predetermined direction, an intermediate gear 36 engaged with the drive gear 34 rotatively moves in the rotating direction of the plate cylinder 2 and the drive gear 34 together with a support arm 35 to engage with an inner pressing gear 37. Then, the gear 36 depresses down and rotates the inner pressing gear 37. In this manner, the inner pressing roll 19 actuated in conjunction with the inner pressing gear 37 presses the peripheral wall 4 toward the rear pressing roll 10 to deform it while rotating in the same direction as the plate cylinder 2. Therefore, the supplied printing paper 12 is fed while being clamped between the peripheral wall 4 with stencil base paper 6 rearward of a claming member 5 and the rear pressing roll 10 to be subjected to stencil printing.

IPC: G03G15/08
Filed: 1990-03-06
Abstract: PURPOSE:To improve dimensional stability by constituting a hub of a material having a coefft. of linear expansion of a specific value or below in environment of temp. of a specific range. CONSTITUTION:The hub has <=6X10<-5>cm/cm. deg.C coefft. of linear expansion in the environment of -10 to 90 deg.C. Namely, the material of the hub is selected from a group consisting of fully arom. polyester, fully arom. polyesters contg. inorg. fillers and polyacetal contg. inorg. fillers. The shrinkage on molding at the time of plastic molding is, therefore, extremely small and the dimensional accuracy of the peripheral surface of the hub is correspondingly good. The high-temp. stability of the finished product is high and the sizes hardly change even after long-term preservation or high-temp. preservation. The dimensional stability is improved in this way.

Abstract: PROBLEM TO BE SOLVED: To facilitate work by forming an under-eaves mounting member with a mounting part mounted under an eaves and an arm extending outside from this mounting part, and by hanging a supporting fixture using a hanging member slidably mounted along the arm. SOLUTION: An under-eaves mounting member 3 is formed with a mounting part 32 in the board state mounted under an eaves and a rod-state arm 31 extending outside from this mounting part 32.

Title: Idling-speed controlling method for internal-combustion engine
Inventor: MURAMATSU MOTOYASU
IPC: F02D41/16
Filed: 1983-03-29
Abstract: PURPOSE:To keep the idling speed always stable, by varying an estimation value according to the altitude in an idling-speed controlling method according to which the flow rate of by-pass air by-passing a throttle valve is changed with the engine load when the engine load is changed. CONSTITUTION:When it is judged by an arithmetic processing circuit 24 that an engine is in its idling operation, an aimed engine speed is determined on the basis of the engine load detected from the output of an air-flow meter 19 or the like, and an air control valve 23 disposed in a by-pass passage 21 is controlled according to the deviation between the aimed engine speed and the actual engine speed detected by an engine-speed sensor 37. Further, when the engine load is changed, overshooting or undershooting of the air control valve 23 is prevented by varying the flow rate of air through the by-pass passage 21 by an estimation value corresponding to the change of engine load. At the time of operating a vehicle at a highland, the estimation value is made greater than that used when the vehicle is operated on a lower land.

Abstract: PROBLEM TO BE SOLVED: To provide a damping force adjusting type hydraulic buffer capable of setting damping forces difference in size from each other in an elongation side and a contraction side and producing a sufficient damping force even during the abnormal operation of a damping force adjusting valve. SOLUTION: A piston 3 is fitted in a cylinder 2, a reservoir 6 is connected. A cylinder upper room 2a and the reservoir 6 are communicated with each other by elongation and contraction side main passages 11 and 12 and the connection part 13 of these passages is communicated with a cylinder lower room 2b by an elongation side passage 14. An opening/closing valve 26 is provided in the elongation side passage 14.
