Abstract: PURPOSE:To shorten the time of disk presence/absence inspection by providing a return light optical path which is embedded in a tray, receiving light which is reflected or cut off by an optical disk CD, and guiding it to a light emitting element. CONSTITUTION:A light emitting element 111 and a light receiving element 112 are fitted horizontally to the top surface of an elevator installed at the reproduction part 510 of a CD player 500 with an L-shaped bracket 115. A sent light optical path 121 and the return light optical path 122 form a V shape and embedded in the tray 511; and the upper part of the optical path 121 faces the element 111 and the upper part of the optical path 122 faces the element 112. The lower part of the V shape extends to the CD mount part of the tray 511 and light emitted by the element 111 is guided into the tray 511 by the optical path 121 embedded along the bottom surface of the tray 511. Then the light is refracted by 90 degree on a mirror installed below the optical path 121. Then the element 112 detects the light through the optical path 122 when the CD is mounted, so the presence or absence of the CD can be detected in a short time.

Title: Spin coater
Inventor: OKETANI HIROI
IPC: G03F7/16
Filed: 1993-01-20
Abstract: PURPOSE:To reduce the consumption of a coating agent and to realize the cost reduction of a product, in a spin coater for forming a coating film on a substrate by providing a solvent ejecting means for applying a solvent to the substrate. CONSTITUTION:In a spin coater having a nozzle 8 for applying a photoresist to a substrate and forming a photoresist film by rotating the substrate 1, a nozzle 10 for discharging a solvent to the substrate 1 is provided. Therefore, when the photoresist film is formed, the solvent is discharged along with the photoresist. Since the photoresist increases in viscosity with the elapse of time, even when centrifugal force due to rotation is utilized, the photoresist gradually becomes hard to spread over the substrate 1 but the rise of viscosity can be prevented by the solvent discharged along with the photoresist and the sliding of the resist on the substrate 1 can be enhanced.

Title: Character processor and kana/kanji conversion method for the same
Inventor: SUZUKI HIRONORI
IPC: G06F17/22
Filed: 1995-01-23
Abstract: PURPOSE: To retrieve even a word, whose reading is not clearly remembered, by converting the part of unknown reading by using a symbol showing the presence/absence of reading, and performing partial retrieval concerning reading. CONSTITUTION: When a complementary symbol '∼' expressing the presence/ absence of reading is inputted while being connected to a character string to show its reading, a microprocessor CPU detects character strings having the character string showing this reading out of a word dictionary TANDIC and extracts the correspondent word, namely, the character string for description. When a number (n) of characters with unknown reading is inputted in relation to the symbol '∼', the microprocessor CPU extracts the character string for description, whose reading is expressed by the (n) pieces of character, to be connected to that reading out of the word dictionary TANDIC. Further, when there is no voiced sound/p-sound in the kana syllabary, word dictionary retrieval is performed while including the voiced sound/p-sound in the kana syllabary in addition to these readings.  Namely, the symbol '∼' expressing the presence/ absence of reading is considered as an arbitrary character string and the converted result can be obtained.

Title: Ultrasonic vortex flowmeter
Inventor: KASHIMOTO HIROO
IPC: G01F1/32
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic vortex flowmeter capable of utilizing two sets of ultrasonic sensors and preventing interference between ultrasonic waves. SOLUTION: A shield plate 20 is disposed in the hollow part 8 of a vortex generator main body 6. Since two ultrasonic wave propagation paths 19 are separated from each other by the shield plate 20, interference between ultrasonic waves transmitted from first and second transmitters 18a, 18b can be inhibited. For a shield plate passage 21, first and second communication ports 13, 14 are arranged at the lower end of a vortex generator 5. Therefore, since gas to be measured flows in opposite directions in the two ultrasonic wave propagation paths 19 separated by the shield plate 20, a receiving phase comparator 25 calculates a difference between two received ultrasonic signals and thereby obtains a value which is twice an original value as the amount of modulation caused by changes in gas flow, so that measuring efficiency can be enhanced.  Simultaneously, the influence of changes in acoustic velocity with which both received ultrasonic signals are afflicted is canceled out whereby accurate flow measurements can be made.

Title: Double tank type solar water heater
Inventor: KATOU YOSHIO
IPC: F24D11/00
Filed: 1981-01-23
Abstract: PURPOSE:To improve the heat collecting efficiency of the captioned water heater by a method wherein two heat accumulating tanks are provided in the water heater and when water in one of the heat accumulating tanks is heated up to a predetermined temperature, the heat collecting operation of a heat collector is switched to the other heat accumulating tank. CONSTITUTION:When the heat collecting operation is started, a heat collecting pipe 9 is made to communicate with a heat exchange circuit 2' through a change-over valve 8 so that cold water in the first heat acculumating tank 2 is heated first. Thus, when the temperature of the water in the tank 2 rises up to, for example, 50 deg.C, a temperature sensor 10 detects it, the valve 8 is turned over to make the heat collector 9 communicate with a heat exchange circuit 3' and water in the second heat accumulating tank 3 is heated. In this case, when a hot water supply circuit 7 is used, the level of the heated water in the second heat accumulating tank 2 lowers temporarily but as the water or hot water in the tank 3 is always kept at a predetermined level, excess water or hot water above that level overlows a water passage 4' and is supplied immediately into the tank 2 through a water passage 5'. Further, when the temperature of the hot water in the tank 2 falls, the valve 8 is turned over and the water in the tank 2 begins to be heated again.
