Patent JP-H11120812-A (JP)
Title: Lighting system
Inventor: MATSUO EIKI
IPC: G02B19/00
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To prevent temperature rise in the vicinity of a light source, and realize high efficiency by reducing the opening number by containing a reflecting optical plane for controlling the spatial distribution on a virtual plane of a main beam of light from the virtual center of the light source and an optical plane to control the direction of the main beam of light from this, and specifying a minimum distance between an electrode contained in a tubular bulb and the reflecting optical plane. SOLUTION: A light flux from an arc in the vicinity of an electrode of a light source 1, such as a discharge lamp, is reflected by a distribution control plane 4a being a reflecting mirror to control the distribution of a main beam of light from the virtual center of the light source 1 in a virtual plane in the vicinity of a direction control plane 4b which is a refracting optical plane. The reflected light passes through the direction control plane 4b and is controlled in its direction, and the opening number of the light flux turns into a constant distribution. An auxiliary image forming device 3 reflects the light flux from the light source 1 and returns it to the light source 1.  Influence of the return light on the vicinity of a tubular bulb and radiation heat by a reflecting surface is relieved by setting an interval D between the tubular bulb of the light source 1 and an optical element such as the distribution control plane 4a to (D>2d) (d is the diameter of the tubular bulb), and cloudiness due to crystallization of the tubular bulb can be prevented.

Title: Channel device
Inventor: SENDA MITSUHIRO
IPC: G06F13/42
Filed: 1987-12-19
Abstract: PURPOSE:To improve data transfer efficiency between a MS access control circuit and an I/O interface control circuit by providing an answer transmission means and a request reception means to said access control circuit and an answer reception means and a request transmission means to said interface control circuit respectively. CONSTITUTION:An I/O interface control circuit 200 sends an answer clear instruction and a request signal to a main storage (MS) access control circuit 100 and clears its own stored answer signal. The circuit 100 stores the received request signal and turns off the answer signal based on an answer clear instruction. Then the circuit 100 sends a request clear instruction and the answer signal to the circuit 200 synchronously with the next system clock and clears its own stored request signal. Then the circuit 200 stores the received answer signal and turns off the request signal by a request clear instruction. Thus the data can be transferred between both circuits 200 and 100 at a high speed.

Title: Cutter replacement method
Inventor: MOTOMURA SHIRO
IPC: E21D9/08
Filed: 1994-12-26
Abstract: PURPOSE: To enhance safety as well as excavation work efficiency by reducing a burden on a worker through the easy replacement of a cutter bit. CONSTITUTION: When a cutter bit 15 mounted on a cutter head 14 is abraded during a tunnel excavation work, the cutter head 14 is made to stop advancing, and radially vibrated under rotation with a parallel link mechanism 29. A tunnel inner wall is thereby excavated and a cavity is formed between the forward end of the cutter bit 15 and the tunnel inner wall. The abraded cutter bit 15 is, then, demounted and a new cutter bit is mounted via the cavity.

Title: Operating device for water supply equipment
Inventor: YANO HIROSHI
IPC: F04D15/02
Filed: 1993-12-21
Abstract: PURPOSE:To prevent the burning of a pump driving motor caused by high frequency operation due to the failure or the like of a pressure tank by stopping water supply when a pump is started during the counting of a timer counting for the specified time period after the end of water supply from plural pumps. CONSTITUTION:When water pressure rises by the driving of two pumps and motor driving relays 8, 9 are de-energized, a timer T counts preset 10 seconds by the circuit of P-8b1-9b1-T-N, and after 10 seconds from energization, a contact Ta is closed, while a contact Tb is opened. Water is used during these 10 seconds, and in the case of a pressure tank being in failure or the like, a pressure switch detects this in association with the sudden lowering of water pressure. A control part thereby closes a contact 7a1 so as to resume the water supply of one pump, and the relay 8 is energized within 10 seconds after the de-energization of the relay 9. The intermittent driving of a motor is then stopped by the energization of a high frequency operation detecting relay 12. An alarm device 13 sounds an alarm for abnormality, and a communication device 14 communicates the abnormality to a monitoring center.

Title: Manufacture of polyolefin resin foam
Inventor: AKIMARU FUSAKICHI
IPC: B29C48/405
Filed: 1987-12-18
Abstract: PURPOSE:To reduce the decomposition of the foaming agent contained in a resin composition to a level which practically does not cause any question and make it possible to sheet polypropylene resin foam excellent in heat resistance, by sheeting a resin composition containing polypropylene resin under reduced pressure with a twin-screw extruder. CONSTITUTION:A polyolefin resin foam is made by forming the mixture of block copolymer polypropylene resin containing 1-35wt.% of ethylene or butene, polyethylene resin with a density of 0.960g/cm<3> or less and a foaming agent to a sheet-like object under a reduced pressure with a twin-screw extruder and thereafter foaming it. Because the shearing heat release of the resin composition in the extruder can be reduced, said composition can be sheeted, whereas it has hardly been sheeted with the conventional single screw extruder. Counter- rotating type of the twin-screw extruder provides its better effect.

The entity of information accumulated in the real information accumulation part 105 is extracted by the retrieved real information pointer. Then, a retrieval/ extraction processing is repeated when the category identifier of the other information and virtual information identifier are mentioned in the entity of extracted information.

Title: Production of piezoelectric material
Inventor: SHIMIZU TAKUYA
IPC: H01L41/39

Abstract: PURPOSE:To suppress deterioration of characteristic properties of piezoelectric material and impart it with stability. CONSTITUTION:A PZT ceramic having a composition in which Pb(Zr0.52, Ti0.48)O3 is incorporated with Sr and Nb is prepared. In the PZT ceramic, the stress of a 90 degree switching in a polarization treatment, which arranges the direction of spontaneous polarization in a specified direction by applying electric field, is removed by an aging treatment and accordingly the PZT ceramic is made to have only a 180 degree switching state. The aging treatment may be performed by e.g. a thermal aging at 200-250 deg.C a temperature changing treatment from -40 deg.C to 130 deg.C and from 130 deg.C) to -40 deg.C which are repeated about 50 cycles or a pressure treatment with a compression stress at 50MPa which is repeatedly applied about 100 times. A piezoelectric material prepared by this process exhibits no deterioration in characteristic properties when compared before and after the durability test applied on the material.

Then the instruction is hited in the cache 2 through an internal instruction data bus 5 with n-bit length. Namely the stored n-bit width instruction to be executed is sent to a decoder 3 through an internal instruction data bus 7 with n-bit length.
