Title: Optical information recording/reproducing device
Inventor: HOSHINO TAKASHI
IPC: G11B7/135
Filed: 1987-04-27
Abstract: PURPOSE:To attain single track recording and multi-track reproducing and to reproduce data at a high speed by synthesizing an light bean from one laser beam generator with one of the plural light beams from another laser beam generator. CONSTITUTION:A light beam outputted from a first laser diode 2 is branched into plural beams by a diffraction grating 3. A light beam outputted from a second laser diode 5 is synthesized with one of said plural light beams by a prism 6. Thus synthesized one light beam and the remaining beams are supplied to an optical disk 1 via a beam splitter 7. The reflecting light beams coming through the splitter 7 are detected by a photodetector 12, and one of the detection signals from it 12 is selected by switches 14a-14c and inputted to a focus control circuit 18. Thus an objective lens 10 is driven and the purpose is accomplished.

Title: Hot water feeder
IPC: F24H1/46
Filed: 1992-03-27
Abstract: PURPOSE:To shorten a hot water feeding waiting time under a simple configura tion in the case that a hot water feeding plug is opened during tepid hot water controlling operation. CONSTITUTION:In the case that a cold water feeding valve is opened to feed cold water (S13), the cold water feeding valve is closed at a specified period, an opening or closed state of the hot water feeding plug is judged in response to a sensing of water flow (S17 to S20). In the case that the water flow is detected (when the hot water feeding plug is opened), tepid water control is terminated. As a result, it becomes possible to eliminate any disadvantage that the hot water feeding is waited until a specified amount of additional water is finished.

Title: Mixed cold/hot waters supply faucet
Inventor: OKUDA TOORU
IPC: F16K31/70
Filed: 1981-06-29
Abstract: PURPOSE:To prevent such a failure in a hot water supplier that the water flows from the cold water side to the hot water side by furnishing a thermo-sensitive valve in each of the high and cold water supply chambers and by providing an openeing/shutting valve which puts the mixing chamber in communication with the hot and cold water supply chambers. CONSTITUTION:When the temperature of hot water to be supplied goes up, exceeding a certain specified value, from a steady state in which the mixture supply faucet is functioning, the form restoration force of a form memory alloy coil spring 7 set in compressed condition will become large to approach the valve element 12 to the valve seat a' and to decrease the flow area of the hot water. If the temperature of the cold water to be supplied, on the other hand, becomes lower than another specified value, the flow area of the cold water will decrease to retain the temperature of mixed water constant. Passages a, b are opened and closed by turning a knob 22, in which the hot and cold waters are prevented from communication to each other at the time of water tap being shut owing to this arrangement where the opening and closing valve is installed in the mixing chamber independent from the thermo-sensitive valve.

IPC: F04D5/00
Filed: 1986-05-06
Abstract: PURPOSE:To retard wear on impeller and liner surfaces and prevent premature loss of water suction performance even if foreign matters such as sand is mixed in the water sucked by making the sand deposit in recessed parts arranged on the impeller surface and by discharging the sand through grooves arranged on the surface of casing liner and others. CONSTITUTION:Multiple recesses 12's are arranged on side surfaces 5A and 5B of an impeller facing liner surfaces 1A and 2A so as not to communicate with a spiral chamber 15 for an impeller 5. With this arrangement, continued wear can be prevented because sand entering a small gap 11 between the impeller's side surfaces 5A, 5B and the liner surfaces 1A, 2A of the casings 1 and 2, is made to deposit in the recesses 12's. Further, the sand deposited in the said recesses 12's is discharged into a spiral water passage 8 through a groove 13 formed from respective peripheries 1B and 2B of the liner surfaces 1A and 2A toward but not reaching respective inner peripheries 1C and 2C. With the above constitution, wear on respective side surfaces and the liner surface 1A and 2A is retarded, premature loss of water suction performance can be prevented, and the reliability of the spiral flow pump is improved.

Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To provide a photo-guide element capable of collecting leaking light from the back surface and also a light source device using the photo-guide element. SOLUTION: The light from a primary light source L is fed to a photo-guide element 10 via an incident end face 12, and internal reflections and leakage occur at the second surface Ti of a row of projections Pi, which are arranged so as to coopreate in linkage for collection of leaked light. The leaked light from the second surface Tj-1 is collected through the first surface Sj and put incident to the second surface internally. This gives a chance of direction change to the collected light. If leakage is generated again, it is collected from the first surface Sj+1. The first surface Si is vertical to the main surface, while the second surface makes a slope, whose inclination angle is designed according to the desirable priority output direction (main emitting direction from the emission surface 13).  The row of projections Pi may also be formed on the photo-guide element 10 by adhesion of a prism sheet, etc. The forefront of the row of projections Pi may have a shape not sharpened.
