Title: Thick film circuit board and manufacture thereof
Inventor: OTA SHINJI
IPC: H05K3/28
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To obtain good adhesion for overcoat glass in spite of less manufacturing process. SOLUTION: Copper plating is applied to conductor patterns 12 on the surface of an alumina laminated board 11 to provide plated electrodes 13. A thick film resistor 14 whose both ends are connected with respective plated electrodes is formed on the alumina laminated board 11. Connecting portions 14b of both ends of the thick film resistor 14 are formed in a size that covers the overall plated electrode 13 and responds to variations in the positions of the plated electrodes 13 due to burning shrinkage of the alumina laminated board 11. Overcoat glass 15 is formed so as to cover the overall upper surface of the thick film resistor 14.

IPC: B29C45/78
Filed: 1987-05-07
Abstract: PURPOSE:To mold a lens without generating strain, by cooling the center part and surface part of a plastic lens molded by injection molding in a specific stage. CONSTITUTION:Cooling water is allowed to flow through cooling pipes 10A, 10B in order to cool molds 2A, 2B. When the flow rate of cooling water is controlled to 0.5l/min, the lens surface temp. and center temp. of a molded lens respectively become temp. curves P1, P2. The surface temp. of the lens is 300 deg.C at the finish point of time of injection (at the start time of cooling) but lowered to glass transition temp. of 160 deg.C as shown by the temp. curve P1 after 17.5 sec. The center temp. of the lens at this time is 289 deg.C and the temp. of the molds is 155 deg.C. As a result of further allowing cooling water to continuously flow at 20 deg.C, the surface temp. of the lens becomes 113.8 deg.C and the center temp. thereof becomes 130 deg.C and the temp of the mold becomes 113.1 deg.C after 90sec and the lens free from deformation and strain is taken out of the mold.

Title: Booster
Inventor: FUNATO AKIHIRO
IPC: H02M7/12
Filed: 1991-04-18
Abstract: PURPOSE:To stably continuously supply a large current to a load required for a large current in an important manner and to stably continuously supply a high voltage to a load required for a high voltage in an important manner by dividing a booster section into at least two systems for supplying a current and a voltage. CONSTITUTION:A booster section B1 for a large current has an inverter 4, large capacity capacitors C7-C9, and diodes D4 D6. B2 is a booster section for a high voltage, and has an inverter 5, small capacity capacitors C10-C12, and diodes D7 D9. The sections B1 and B2 output three times voltage of a power source voltage by an oscillation output of an oscillator A. Since the section B1 has large capacities of the capacitors C7-C9, it can sufficiently supply the current to be required. Since the section B2 boosts independently of the section B1, it can stably supply a high voltage.

Title: Holding device for cylindrical body
Inventor: AOKI MOTOHISA
IPC: B05C13/02
Filed: 1982-06-29
Abstract: PURPOSE:To enable immersing and coating of only the outer surface without touching the holding device to the outer surface of a cylindrical body, by making a bag provided in the holding device expandable and contractible and locking with the inner wall of the cylindrical body by frictional force at the time of expansion. CONSTITUTION:With a rubber bag 5 contracted, a cylinder 3 is inserted vertically to the middle of a cylindrical body 7. When air is introduced from a rod 1 to the rubber bag 5 by pressure, the rubber bag 5 inflates and comes into close contact with a groove 4 and inner wall of the cylindrical body 7, and shuts off circulation of air between the cylinder 3 and cylindrical body 7. When air pressure in the rubber bag 5 is made sufficiently high, the cylindrical body becomes suspended state by the rod 1 due to frictional force between the rubber bag 5 and inner wall of the cylindrical body. This is immersed vertically into liquid and then pulled up vertically. As air is sealed in a space 8 in the lower part of the cylindrical body, the liquid hardly goes in when immersing, and only the outer surface of the cylindrical body comes into contact with the liquid.

IPC: C23F11/00
Filed: 1992-05-01
Abstract: PURPOSE:To constitute the title method so that dripping of a rustproof liquid to be generated on the lower part of an iron reinforcing rod can be reduced, by a method wherein, at the time of application of rustproof coating to the iron reinforcing rod for lightweight foam concrete, after immersion of the iron reinforcing rod into the rustproof liquid, the iron reinforcing rod is tilted and a vibration is applied to the same. CONSTITUTION:In the case where rustproof application treatment is performed to a cage 1 made of an iron reinforcing rod for lightweight foam concrete, a large number of the cages 1 (for example, 30 cages) are fitted to a setting jig (setting frame) 2 for setting them in a mortar molding concrete shuttering. Then after the cage 1 made of the iron reinforcing rod fitted to the jig 2 is immersed within a rustproof coating within a rustproof coating tank 3 for about 5 seconds and the same is taken out, the same is inclined at an angle of about 25 degrees by an inclining device 4 to swish the liquid off from the cage made of the iron reinforcing rod and swishing-off of the liquid is to performed about 20 seconds. Simultaneously with the above, the swishing-off of the liquid is quickened by applying a vibration wherein a number of vibrations are about 10000 v.p.m. and the whole amplitude is about 4mm to the cage of the iron reinforcing rod by a vibrator 5. With this construction, the swishing-off time of the rustproof liquid is shortened and dripping of the liquid is reduced drastically.
