Title: Device for conveying powder body
Inventor: KUREMATSU KATSUMI
IPC: G03G15/08
Filed: 1985-08-06
Abstract: PURPOSE:To properly convey powder bodies having the same polarity, as with the polarity of a particle such as said powder body by providing a means of controlling an alternating deriving voltage applied to an electrode. CONSTITUTION:Electrodes 2 have the same structure as an ordinary electric field curtain and are set in parallel and at equal intervals on a substrate 1. Three-shape voltage wave forms are outputted from a driving power source and a control means 3 and each phase is applied to every third electrode 2 in order. Accordingly, the arrangement of phases in the order of PHI1, PHI2, PHI3 is repeated corresponding to the arrangement of the electrodes. When a driving voltage is applied to each electrode, a particle 4 having negative toribo-polarity is conveyed in the direction of the arrow while a particle 5 having position toribo-polarity is conveyed in the opposite arrow direction. Thus, the powder body particles on the electric field curtain can be separated according to their toribo-polarity, due to the action of the particle the conveying direction of which is differentiated by its toribo-polarity.

Title: Pulse generating element with temperature sensing function
Inventor: ENDO KAZUMITSU
IPC: G01N27/72
Filed: 1994-07-25
Abstract: PURPOSE:To obtain a pulse generating element with a temperature sensing function for sensing a specific temperature by inserting a magnetic material which exhibits a Barkhausen effect by applying a tensile stress into a shape memory alloy tube in which its inner diameter is reduced at the specific temperature. CONSTITUTION:Positive and negative pulse voltage is obtained from the vicinity of 25 deg.C upon shape change of a shape memory alloy tube from the relationship between the pulse voltage induced in a detecting coil 3 and a measuring temperature. Thus, a strand is inserted into the tube thereby to obtain a pulse generating element 2 which can sense a predetermined temperature. A magnetic material which exhibits a Barkhausen effect by applying a tensile stress is inserted into the tube in which its inner diameter is reduced at the predetermined temperature, and hence the shape of the material is changed corresponding to the temperature change. Accordingly, the effect can be retained and the temperature can be easily sensed.

Title: Image display device
Inventor: FUJII EIJI
IPC: G02F1/136
Filed: 1989-07-06
Abstract: PURPOSE:To secure a large loading capacity and to maintain information despite of a miniaturized picture element by forming a thin film which has greater permittivity than a silicon oxide film and a gate, on a part of polysilicon of a thin film transistor constituted of the gate, the silicon oxide film and the polysilicon. CONSTITUTION:After a positive polysilicon film 12 is placed on a quartz substrate 11, the film is insularly formed by etching, and impurity ions are implented into a part becoming loading capacity. After the silicon oxide film 13 is formed as a gate oxide film, the silicon oxide film 13 for the only part of the loading capacity is removed. Then, a silicon nitride film 15 is formed, the film except for the part of the loading capacity is removed and a gate polysilicon film 14 is piled up. Under this constitution, the loading capacity size is ten times as large as a normally constituted picture element. Although the picture element capacity is declined accompanied by the miniaturization of the picture element, the great loading capacity is secured, and thereby, the maintained information is never leaked by a leak current.

Title: Hot-water heater
Inventor: OBARA HIROKI
IPC: F23N5/02
Filed: 1992-06-30
Abstract: PURPOSE:To use two stages to check on a hot-water heater for the purpose of detecting any residual fire and putting it under control in order to heighten the safety of the apparatus against residual fire. CONSTITUTION:A controller 6 for the control of the combustion in a hot-water heater has a first safety function which, in response to a detection output of a high-limit switch 10, forces the burner 4 to act to extinguish the fire and also a second safety function which, when the temperature detected by a feedwater-temperature sensor 7 is judged to be higher than the temperature detected by a hot outflow-temperature sensor 9, forces the burner 4 to act to extinguish the fire. Thus the use of a high-limit switch 10 and the use of a feedwater-temperature sensor 7 in conjunction with a hot outflow-temperature sensor 9, even if the high-limit switch 10 should malfunction, enables detecting and putting under control in one of the two stages any residual fire that may remain when a water-flow sensor 8 malfunctions.

Filed: 1991-06-19
Abstract: PURPOSE:To offer a direct-read-after-write(DRAW) type compact disk to which data can be easily recorded in the case of recording plural data of prescribed length to the DRAW type compact disk. CONSTITUTION:In the case of recording plural data of the prescribed length, aiming at that table of contents(TOC) can be generated before the data is recorded, the TOC is recorded beforehand in the recording area of the DRAW type compact disk by another recording device prior to the recording of the data of the prescribed length. As for this recording form, normalized form formed by dividing a track-form recording area into plural sections of prescribed size, and recording previously the TOC determined from the fixed length of the data to be recorded in, at least, one of plural sections in order to record afterward the data in a DRAW way in this one section is adopted. Accordingly, the write-in of the TOC is executed by an inexpensive general purpose processing system, and it need not be executed by a data recording device for recording the data of the prescribed length. Then, a TOC editing function can be excluded from the data recording device, and the expensive data recording device can be used efficiently.
