Title: Electroluminescent lamp
Inventor: ITO NAOYA
IPC: H05B33/02
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To prevent deformation or thinness in each layer caused by a protrusion and prevent lowering of insulation and generation of short-circuiting even if positioning and fixing an electroluminescent lamp are made after pressing against a circuit board having a minute protrusion such as a circuit element terminal, by forming an uneven part on an outer surface of a rear surface electrode. SOLUTION: An uneven part 21 is formed on an overcoat layer 7 by a screen printing by use of resin. A required characteristic for the uneven part forming resin is that the strength to the compressed direction is large, and a melamine resin, acryl resin or the like is preferable for the resin. In the case where this electroluminescent lamp 22 is disposed on a circuit board 12, a protrusion such as a tip 20a of a terminal 20 of a circuit element 16 is stored in the uneven part, and thereby the protrusion does not press the layer 7 locally. Accordingly, the purpose is attained.

Title: Control mechanism for recovering by-produced nitrogen
Inventor: SASAKI EISEI
IPC: C01B13/02
Filed: 1986-10-24
Abstract: PURPOSE:To permit utilization of by-produced nitrogen at a pressure close to atmospheric pressure by installing four control valves and a compressor to a conventional oxygen generating apparatus. CONSTITUTION:Compressed air supplied from an intake port A is allowed to pass through a valve V1 by opening control valves V1, V4, V8 and closing V2, V3, V6, V7, V10 at the time tau1 and tau8 to adsorb N2 to a cartridge C1, and O2 is conducted to an exhaust port OX through the valve V5. The valve V6 is closed at the beginning of the time tau1 and the valves V4 and V8 are opened. Thus, the air and oxygen remaining in the both sides of the cartridge C2 by the internal pressure of introduced compressed and adsorbed N2 are exhausted through the valves V4, V8, and V9 and an exhaust port EX to the outside air. Then, the valves V4 and V9 are closed and valve V10 is opened at the end of the time tau8 to extrude the N2 adsorbed to the cartridge C2. And, the compressor CMP is driven to extrude the gas out of the exhaust port N.

Title: Bed mat
Inventor: TANAKA HIDEHIKO
IPC: A47C27/00
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To provide a bed mat which enables a sick person to spend time comfortably as air flow passages are formed on the bed mat even if the front surface of the bed mat is covered with a water impermeable synthetic resin film. SOLUTION: The bed mat is constituted by affixing the water impermeable synthetic resin film 2 formed with wrinkles 2' on its front surface on the front surface of a mat material 1 produced from rubber, urethane foam, etc. As a result, clearances 4 are generated between the human body 3 and the synthetic resin film by the ruggedness on the front surface formed by the wrinkles of the synthetic resin film. Since air flows in these clearances, the moisture generated on the bed mat is removed and, therefore, the proliferation of bacteria, etc., is suppressed and the sick person is kept free of moistening. The finest environment offering the good comfortability to lie down is thus created.

Title: Bus monitor circuit for information processor
Inventor: SUDO YASUSHI
IPC: G06F11/34
Filed: 1991-10-01
Abstract: PURPOSE:To easily obtain information required for investigating the cause of occurring a fault and to execute a countermeasure against the fault in a short time. CONSTITUTION:When the fault is detected at an input/output bus B2 by a fault detection circuit D3, data turning a bit corresponding to the fault to '1' are outputted. A register R5 holds data turning the bit corresponding to the fault to the '1' to output a stop signal to a memory control circuit M7, and an AND circuit A8 ANDs the data from the detection circuit D3 and the data from the register R5 for each bit. When there is only one pair of bits establishing the AND, an OR circuit 09 outputs the stop signal to the control circuit M7. The memory control circuit M7 always fetches an address, data and control signal from the bus B2 and stores them and when the stop signal is inputted, however, the circuit M7 stops fetching signals and holds an information processor fetched from the input/output bus B2 during a fixed period before the generation of the fault.

Title: Method and apparatus for producing platen roller
Inventor: WARATANI KENICHI
IPC: B29C45/26
Filed: 1985-11-13
Abstract: PURPOSE:To obtain a rigid or flexible high-quality platen roller the surface of which has no foam, by mixing a composition comprising a polyol as a main constituent with an isocyanate through collision under a high pressure, and injecting the resultant mixed liquid into a mold in which a metallic core to become a rotary shaft is inserted. CONSTITUTION:A metallic core 2 is fitted to a lower mold 5, and mold clamping is carried out by moving the lower mold 5 upward while moving an upper mold 4 and an upper mold pressing plate 6 downward. A composition comprising a polyol as a main constituent and an isocyanate are mixed through collision against each other under a high pressure in a mixing head 11. The resultant mixed liquid is injected from an injecting port 12 into a cavity 10 through an injecting gate 13. When molding a material having a rigid and flexible skinned foamed structure, 1/3-1/4 of the entire volume of the cavity 10 is filled with the fluid material so that the entire volume will be filled up as the subsequent foaming action proceeds. Further, a hardening reaction is effected through auto-heat-generation. On the other hand, when molding a material having a semi-rigid elastomer structure and comprising no foaming agent, the material is so injected as to fill up the entire volume of the cavity 10, and is hardened through auto-heat-generation.
