Title: High temperature gas-insualted transformer
Inventor: SHIOZAKI MORIO
IPC: H01F27/20
Filed: 1989-11-30
Abstract: PURPOSE:To provide a gas-insulated transformer which can normally be used at high temperature by using a gas, whose main component is silicon fluoride, as an insulating gas. CONSTITUTION:A gas-insulated transformer, normally used at a temperature not less than 120 deg.C and less than 500 deg.C, can be obtained by using a gas, whose main component is silicon fluoride, for insulation. As the silicon fluoride, silicon tetrafluoride SiF4, disilicon hexafluoride Si2F6, silicon trifluoride SiHF3, etc., are known, but herein, silicon tetrafluoride SiF4 is most preferable from the view point of manufacturing cost, etc. Silicon tetrafluoride SiF4 is a colorless gas with irritating odor, and sublimates at -95 deg.C at latm. It violently reacts on water content, but it is stable in a dry state and does not react even on glass or the like. In the case wherein SiF4 gas is used, it is important to keep the inside of the container in a dry state to stabilize the gas composition.

IPC: F04D29/28
Filed: 1990-11-14
Abstract: PURPOSE:To decrease efficiency loss caused by secondary flow and improve air sending efficiency by arranging protrusively short blades curving at an angle of delay to the rotating direction of an impeller on the top face in the outer peripheral part of a front shroud of the impeller. CONSTITUTION:Plural number of short blades 32 curving at an angle of delay to the rotating direction of an impeller 25 are arranged protrusively on the top face in the outer peripheral part of a front shroud 33 of the impeller 25. When the impeller 25 rotates, air flow is discharged from a blow-off port 35 of the impeller. Though a part of the air flow discharged from the blow-off port 35 of the impeller tries to enter into an inlet port 37 of the impeller by passing through the space 36 between a casing 21 and the front shroud 33, it is pushed back in the direction of the blow-off port 35 by means of the short blades 32 curving at an angle of delay to the rotating direction of the impeller 25. Thereby, secondary flow flowing into the space 36 can be reduced so that an electric blower having a high air sending efficiency can be obtained.

Title: Image forming device
Inventor: KOJIMA TAKEO
IPC: G06F15/00
Filed: 1999-11-01
Abstract: PROBLEM TO BE SOLVED: To provide an image forming device for managing the life of parts by a non-volatile memory with a capacity being as small as possible. SOLUTION: A planned replacement number of sheets (planned replacement time) concerning each kind of parts incorporated in the image forming device, i.e., a value obtained by adding a previously set life number (life time) at every kind of parts to the total printing number of sheet (total printing time) up to the replacement is stored in the non-volatile memory. When the total printing number (total printing time) exceeds the planned replacement number of sheet (exchange plan time), the life of the parts is judged to be expired. Thus, an information amount required for managing the life of the parts is made to be small so that the capacity of the non-volatile memory is reduced to lower a cost in the device.

Filed: 1988-12-09
Abstract: PURPOSE:To prevent black inversion without causing white/black level inversion by providing 1st and 2nd positive feedback circuits switched selectively in parallel with a limiter receiving an input FM signal. CONSTITUTION:When a level of an input FM signal from a high pass filter 4 is large, a level detection circuit 28 throws a switch 27 to the position of a contact (a) to insert a positive feedback circuit 20. In this case, a limiter 13 is saturated and feedback quantity is reduced, the circuit characteristic is made flat. When the level of the input FM signal reaches a prescribed level or below, the level detection circuit 28 throws the switch 27 to the position of a contact (b) to insert a positive feedback circuit 21. The circuit keeps an average level of a noise bar in the input FM signal within a prescribed level range. Thus, no white/black level inversion takes place and black inversion is prevented.
