Title: Power steering mechanism
Inventor: EMORI YASUYOSHI
IPC: B62D5/06
Filed: 1979-05-09
Abstract: PURPOSE: To make the sensation of steering better and to enable also the use for the power steering device of a single front-axle vehicle by conducting the control of supply and discharge of the pressure oil for an auxiliary power cylinder by a control valve part of the power steering device and transmitting the output to front wheels.  
     CONSTITUTION: When a steering handle 11 is operated, a motion is transmitted to a main shaft 10 and an input shaft 6 and the oil-hydraulic circuit of a control valve part is changed over in accordance with the rotational direction of the input shaft 6. As a result, high-pressure oil is led into a power cylinder inside a power steering device 5, an output shaft 12 being rotated and its output being transmitted to the 1st front wheels 3 through the 1st drag link 14, a slave lever 15, the 2nd drag link 16 and a knuckle arm 17. Simultaneously, the pressure is transmitted from the slave lever 15 to the 2nd front wheels 4 through a connecting rod 21, a slave lever 20, a link 18 and a knuckle arm 19.

Title: Fluorescent lamp
Inventor: NISHIKATSU TAKEO
IPC: H01J65/00
Filed: 1988-03-10
Abstract: PURPOSE:To reduce a change with the passage of time of the optical output for securing a long life by providing two mutually opposing parts, to which no phosphor is applied, on the inside of a glass tube and arranging conductors on the glass tube outside of these parts respectively. CONSTITUTION:Gas 2 such as rare gas and mercury vapor are sealed in the inside of a glass tube 1 and a phosphor 3 is applied to the inside of the glass tube 1. However, the phosphor 3 arranges the opening parts (the parts having no phosphor 3) 9a and 9b in the tube axis direction in the two diametrically opposing places on the glass tube inside and the respective conductors 4a and 4b are arranged on the outside of the glass tube 1 of these respective opening parts 9a and 9b. Accordingly, the phosphor 3 does not exist in the parts of the conductors 4a and 4b receiving a shock of electrons and ions so that there is no danger of generating remarkable deterioration of the phosphor due to the shock of electrons and ions. Thereby, a change with the passage of time due to deterioration of an optical output is little so that a long life can be secured.

Title: Magnetic shield body mounting structure of color picture tube
Inventor: ENDOU TOMIHIDE
IPC: H01J29/06
Filed: 1984-03-22
Abstract: PURPOSE:To absorb excessive stress produced when mounting a magnetic shield to a tube frame and prevent causing strain to the frame by providing cut portions on both sides of the base of a tongue projected out from the end portion of the magnetic shield. CONSTITUTION:Cur portions 12d are formed on both sides of the base of a tongue 12b projected out by locally cutting a flange portion 12a of a magnetic shield body 12. In this structure, when a holder 13 is installed to the body 12 and the magnetic shield body 12 is mounted to a frame 9, a projection 13b of the holder 13 is directly pushed against the outside surface of the tongue 12b of the magnetic shield body 12. Therefore, the tongue 12b moderately deflects against excessive pushing of the projection 13b. This means that in the jointing of the frame 9 and the magnetic shield body 12, excessive stress due to such as processing error is absorbed by the deflection of the tongue 12b at the cut portions 12d, preventing excessive strain from occurring on the frame 9 due to the excessive stress.

Title: Fuel pump
Inventor: MURAKAMI SADATOSHI
IPC: F04B53/20
Filed: 1988-03-09
Abstract: PURPOSE:To prevent a magnetic small substance in a tank from being fed to a fuel transfer system in a simple structure by setting up a magnet for catching and removing the magnetic small substance, in a filter of a fuel pump. CONSTITUTION:A magnet 6 molded in such a form as not affected to negative pressure in a pump is set up in the inner part of a filter 5 attached to a fuel pump suction port 4. In this case, capture for a magnetic small substance takes place even if a form of this magnet 6 is in a simple structure such as rectangular, circular, oval forms or the line with constant thickness. When the magnetic small substance is magnetically attracted by the magnet 6, it is the wider in the surface, the larger in the attracting effect, so that it is yet more effective if being constituted into perforation, irregular form or reticulation. With this constitution, abrasion accelerating factors in a commutator and a brush for a fuel pump motor are thus eliminable.
