Title: Boost control valve
Inventor: WADA HIDEO
IPC: F16D48/00
Filed: 1986-06-17
Abstract: PURPOSE:To utilize a boost control valve effectively by arranging a piston slidably at the cylinder section while separating from a plunger and providing a check valve for feeding/discharging the pressure oil through an orifice to the piston. CONSTITUTION:A valve body 3 is provided with a primary side port 5 for feeding the pressure oil and a secondary side port 6 for discharging the pressure oil. A plunger 9 is fitted slidably to the cylinder section 7 while being energized in the direction of the port 5 by means of a spring 10 and a piston 11 is also energized in the direction separating from the plunger 9 by means of the spring 10. A spring 15 is inserted over a projecting section 11c so as to press the plunger 9 in the direction of the port 5 when the piston 11 is moved by full stroke. In order to discharge the oil, a check valve 21 moves in the direction for releasing an orifice hole 21a while resisting against a spring 22 thus discharging the pressure oil in a piston chamber 12 smoothly.

Title: Dial for telephone system
Inventor: TAKITA HAJIME
IPC: H04M1/26
Filed: 1989-06-02
Abstract: PURPOSE:To improve the operability by deciding a count with a manual switch, sending the decided count to a connection line and eliminating the need for dial buttons 10-12. CONSTITUTION:When a handset 3 is lifted up, a pulse dialing section 11 generates a pulse, sends a pulse to a counter 12, it is displayed on a display device 14 one by one digit to appeal it to the visual sense of the operator and a simulated sound is generated from a simulating sound generating section 15 simultaneously, the simulated voice is sent to the handset 3 to appeal it to the visual sense of the operator. The operator recognizes whether or not the number is a number required at that time by the operator and depresses a decision switch 16. The numeral or symbol decided thereby is fed to an NCU section 1 and sent to the connection line as a dial signal. The succeeding digit is operated similarly and sent to the connection line as the dial signal.

Title: Method and device for shifting roll in roll leveler
Inventor: MASUDA BUNPEI
IPC: B21D1/00
Filed: 1983-08-02
Abstract: PURPOSE:To improve the durability of a roll and its operating efficiency by using the roll while shifting it in its axial direction for preventing the roll from generating defects and dispersing the defects. CONSTITUTION:When a defect such as roll wear generates a little in the surface of a leveling roll 2, a cylinder 10 is extended as shown by the imaginary line to move a holding frame 9, which holds a roll chock 7 through a bracket 12, along a supporting bed 8. The leveling roll 2 is shifted in the axial direction in a state of being mounted on a backup roll 3. By performing properly said operation at every pass, a defect generating in the roll 2 is dispersed uniformly in its axial direction; then the durability of roll 2 is improved, and the frequency of roll replacement is reduced.

Title: Manufacture of passivation film
Inventor: CHINO TOYOJI
IPC: H01L21/312
Filed: 1991-06-13
Abstract: PURPOSE:To reduce the leak current by forming an oxide film on the surface of a compound semiconductor while controlling the solution temperature in hydrogen peroxide aqueous solution, and applying polyimide resin on the oxide film, and hardening this polyimide resin. CONSTITUTION:When an InP oxide film 16a is made on an InP substrate 11 by the solution where iron (III) ions are added to hydrogen peroxides or hydrogen peroxide water or hydrogen peroxide water, the composition of the substrate 11 changes gradually to that of the oxide of the substrate 11, so sudden composition change does not occur, and defects are hard to occur in the substrate 11. On the other hand, the polyimide resin 16a is hard to cause stress by the oxide film 16a. Accordingly, by applying and hardening the polyimide resin 16b after forming the oxide film 16a to avoid the sudden composition charge between the substrate 11 and the passivation film, the occurrence of the stress and the defect can be reduced. Hereby, leak currents can be reduced.

Title: Submerged arc welding method of high-carbon steel
Inventor: SUGIOKA ISAO
IPC: B23K9/18
Filed: 1983-08-03
Abstract: PURPOSE:To prevent high-temp. cracking and to improve welding efficiency in submerged arc welding of a high-carbon steel by limiting the sum of and difference between preceding electrode current and succeeding electrode current as well as an inter-electrode distance and subjecting at least one side to single-layer build-up welding with two electrodes. CONSTITUTION:Welding of a high-carbon steel contg. 0.20-0.33W% C is accomplished by regulating the sum of preceding electrode current and succeeding electrode current to >=1,200A, the difference between the succeeding electrode current and preceding electrode current to 0-200A and an inter-electrode distance to 25-50mm., respectively. If the sum of both electrodes is <1,200, there is substantially no effect in terms of efficiency. High-temp. cracking arises when the preceding electrode current is higher than the succeeding electrode current. An undercut and consequent defective appearance arise when the succeeding electrode current has over 200A difference from the preceding electrode current. High-temp. cracking arises at <25mm. inter-electrode distance. The unstable arc and consequent defective bead appearance arise if said distance exceeds 50mm..

Filed: 1998-05-25
Abstract: PROBLEM TO BE SOLVED: To thaw snow in a high thermal efficiency by laying cement mortar on a base course to form a heat insulation layer and then, laying cottony heat- generating bodies on the heat insulation layer at every required distance and paving the heat insulation layer on which the cottony heat-generating bodies are laid, with asphalt. SOLUTION: Cement mortar containing a perlite foamed body is applied on a base course 1 to form a heat insulation layer 2 and cottony heat-generating bodies are laid on the upper face thereof at every required distance and further paved with asphalt 4 to obtain a snow-thawing road. That is, the cottony heat- generating bodies are not directly laid on the base course but a heat insulation layer is provided and the cottony heat-generating bodies are laid thereon. In this way, the heat generated from the cottony heat-generating bodies can be transferred to thaw snow on the upward alsphalt face (roard face).  Further, since the heat generated from the cottony heat-generation body is diffused to the periphery of the heat-generating bodies at a metallic layer by covering the cottony heat-generating layer on the heat insulation layer with the metallic layer, snow-thawing can be more accelerated.
