Title: Picture tube
Inventor: MIYAMA HIROSHI
IPC: H01J29/32
Filed: 1983-01-14
Abstract: PURPOSE:To reduce the number of electrodes and prevent the color unevenness of a picture by forming the thermions generated from a linear hot cathode into a uniform electron beam by means of a beam extraction electrode and a beam acceleration electrode and vertically deflecting, horizontally splitting, and modulating it, and stimulating a phosphor stripe in the relationship of one to one correspondence. CONSTITUTION:A linear hot cathode 13 generates thermions by applying preset voltage to its both ends. The thermions are shaped into an unidirectional band- type electron beam by the potential that is produced by a rear electrode 12 and a beam extraction electrode 14 and pass through a long and narrow slit-type opening section. Then, the electron beam passes through an acceleration electrode 15 with almost the same shape as the beam extraction electrode 14 and then passes through a vertical deflection plate section 16. Subsequently, when the beam passes through matrix modulation sections 17A and 17B, it is horizontally split, modulated, and accelerated, and then forces a preset phosphor 19 formed on the inner surface of the glass enclosure 20 of a face section to emit light.

Title: Electromagnetic type proportional control valve
Inventor: TANAHASHI TAKASHI
IPC: F16K31/06
Filed: 1980-01-19
Abstract: PURPOSE: To use an electromagnetic type proportional control valve which controls the flow rate of gas, etc. stepless-proportionally for a long time and stably by sealing the fluid and atmospheric air without using a diaphragm and anti-vibrates a valve body by means of an anti-vibrating plate spring.  
     CONSTITUTION: When a valve body 29 is pressed on a valve seat 15 by a coil spring 30, it closes. The spring force actuated on a plunger 27 is the sum of the force of two support plate springs 26 and a coil spring 30. When current is applied to a coil 24, magnetic force is generaed and the plunger 27 is lift upward. In this case, the point on the support plate spring 26 to which an anti-vibrating plate spring 34 makes contact is P' which differs from point P. The anti-vibrating plate spring 34 slides on the support plate spring 26 between the points P and P' and sliding resistance is generated. This slide resistance generates the direction which stops the movement of both plate springs. Since this stops the vibration of the valve body 29 and the plunger 27, electromagnetic type proportional control functions cannot be damaged.

Inventor: KAWANA SEIZOU
IPC: C02F1/06
Filed: 1983-01-18
Abstract: PURPOSE:To decrease the pressure drop of steam occurring in tube bundles by decreasing the diameter of the tube bundles and to improve heat exchanging performance by forming a condenser in each stage into a double pass type, bisecting each tube bundle at the side partition wall and using each thereof for single pass. CONSTITUTION:The flow of the low-temp. water in the heat transmission tubes in one stage 1 flows like an arrow 10 with respect to one tube bundle 8a, and enters the outflow chamber 12 thereof. The water from the chamber 12 flows through a communicating tube 14 and enters the inflow chamber 13 of the other tube bundle 8a. The water flows in the opposite direction like an arrow 11 with respect to the other tube bundle 8b. More specifically, the low temp. water in one stage 1 flows to the adjacent stage after performing exactly a U turn and the similar operation is repeated in each stage as well. If such constitution is incorporated, the diameter of the tube bundle is decreased and the pressure drop of steam occurring in the tube bundle is decreased, whereby the heat exchanging performance is remarkably improved.

Title: Method for marking on surface of metallic roll for rolling and resist agent for marking used therein
Inventor: IMAE TOSHIO
IPC: B23K26/00
Filed: 1992-01-16
Abstract: PURPOSE:To enable the execution of working on a metallic roll for rolling having a broad width and the reduction of initial costs by using the agent. CONSTITUTION:The nonphotosensitive resist agent is applied on the surface of the metallic roll for rolling to form a resist film of an uncured state. Patterns are marked on the resist film and the resist film is partly thermally cured by a laser beam which has the energy density necessary for initiating a thermal curing reaction and is cast impulsively at such an energy density as not to generate the thermal decomposition of the cured resist film. The uncured resist film is then removed and after recessed parts are formed by an etching treatment, the cured resist film is removed. The patterns are thus applied on the roll surface.

Filed: 1987-01-13
Abstract: PURPOSE:To maintain the uniformity of the precision of a pattern formed in a resist film extending over, the whole substrate to be treated by shaping structure, in which a forced exhaust air current flowing on the resist film can be controlled so as to bypass a path separate from the substrate to be treated during a developing treating process, in order to avoid the nonuniformity of the temperature distribution of a developer film resulting from said air current. CONSTITUTION:A first masking shield 70 is formed in a rotary slant face with an opening 71, and a plurality of ventilating holes 72 are shaped along the outer periphery of the masking shield. A second masking shield 80 similarly has an opening, and can be moved vertically while the opening section is brought into contact with thc outer circumferential surface of a cylindrical barrier 12. The outer circumference of the masking shield 80 is brought into contact uniformly with the lower surface of the masking shield 70 at an uppermost position thereof. An air current flowing in from a clearance between a semiconductor substrate 21 and the masking shield 70 is prevented under the state in which the masking shield 70 and the masking shield 80 are brought into contact, and only air currents pass through the ventilating holes 72. Accordingly, the masking shield 80 is controlled so as to be positioned at the uppermost position, thus obviating the generation of the nonuniformity of temperature distribution resulting from a high-speed air current on the outer circumferential section of the semiconductor substrate 21.

Title: Temperature detector
Inventor: KOU TADAHARU
IPC: G01K5/62
Filed: 1980-01-23
Abstract: PURPOSE:To improve mechanical strength and sensitivity by utilizing an optical fiber and a bimetal. CONSTITUTION:An optical fiber 5 is made in one piece with bimetals 1, so that it follows up the movement of the bimetals 1. A light emitting element 7 is disposed to one end of the fiber 5 and a photodetector 6 via a slit 8 to the other end. Then, while the bimetals 1 are straight, the light emitted from the light emitting element 7 does not enter the photodetector 6 even if it emits from the other end of the fiber 5, and no current flows to the load 3 to be controlled by a temperature. However, when the bimetals 1 curve on account of rise in the temp., the optical fiber 5 follows up the same as well, and the exit light enters the photodetecdor 6 through the slit 8, thereby causing the current to flow in the load 3. Hence, the on and off of the switch by temperature changes are made contactless, there is no degradation owing to contact wear and the sensitivity improves.
