Title: Master-slave shield machine
Inventor: UEHARA TOSHIAKI
IPC: E21D9/06
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To reduce interferences in peripheral equipments, and to take the quantity of eccentricity and the sectional area ratio of holes at large values by installing an eccentric rotary means into the master machine of master-slave shield machines and bringing the slave machine to an eccentrically movable state. SOLUTION: The diameter of a slave machine 3 is made smaller than that of a master machine 2 and the slave machine 3 is made concentric to the master machine 2 and held detachably. A drum member 6 is supported to the lower frame of a master-machine shield frame from a lower section through a plurality of rollers, and can be rotated centering around a center C1 . When a hole having a large cross section is excavated, an outer circumferential cutter 20 and a slave machine cutter 16 are turned and driven centering around a center Co and excavation is conducted by a hydraulic motor for driving while performing propulsion by a master-machine shield jack. A hydraulic motor 46 for eccentric rotation is braked at that time, and the revolution of the drum member 6 is stopped.  When a hole having a small cross section is excavated, the drum member 6 is revolved by the hydraulic motor 46, and the whole slave machine 3 is rotated eccentrically centering around the center C1 to an upper section, and moved to an eccentric place. Accordingly, the quantity of eccentricity of the slave machine 3, the quantities of eccentricity of the large and small holes, and a sectional area ratio are taken at large values.

Title: Discharge lamp lighting device
Inventor: ITO KAZUHIKO
IPC: H05B41/24
Filed: 1988-08-01
Abstract: PURPOSE:To surely perform starting, lighting and dimming as well as a stop of oscillation in an emergency by providing a circuit for dimming and an emergency detection circuit. CONSTITUTION:At the time of starting a dimming mode of a fluorescent lamp 7, a reset circuit (a) 33 is in operation by a timer circuit (a) 32 so that an emergency detection circuit 34 is made null and the fluorescent lamp 7 gets a state of all output lighting. After the lapse of a fixed time, the circuit (a) 32 stops the operation of the circuit (a) 33, the dimming circuit 31 operates and the lamp 7 is dimmed. At the time of emergency of the lamp 7, when the circuit (a) 33 is stopped after a fixed time by the circuit (a) 32, a signal of the emergency detection circuit 34 is outputted to a stop circuit 35. Then, the oscillation operation of a switching circuit 11 is stopped from a circuit 35 through a driving circuit 30. Further, since the circuit 34 consists of an electron circuit, whose detection level gets variable by changing resistance value of the resistors 53 and 53, repeated ON-OFF and a sure stop of oscillation can be performed regardless of lamp voltage and a surrounding temperature. Furthermore, in a normal lamp a reset circuit makes it possible to surely light while being translated to dimming.

Title: Car air conditioning device
Inventor: SUMIKAWA SEIJI
IPC: B60H1/32
Filed: 1984-09-17
Abstract: PURPOSE:To prevent a compressor form being burnt out by configurating a device in such a manner that an equivalent saturation temperature of refrigerant is determined by refrigerant pressure allowing a difference in temperature from refriigerant temperature to be compared with reference value so as to suspend the compressor operation with an indication displayed when refrigerant is determined to be insufficient in volume. CONSTITUTION:Both a refrigerant temperature T and pressure P are detected by sensors 11 ans 12, and are inputted into a control unit 15. Consequently, a conversion device 17 of the control unit 15 allows an equivalent saturation temperature T2 of refrigerant to be computed based on refrigerant pressure P arriving at a difference DELTAt in temperature to a refrigernat temperature T1. A decision device 18 allows the difference DELTAt to be compared with a reference T0 to see if refrigerant is insufficient in volume. If refrigerant is determined to be insufficient in volume, a lamp 24 of an indicating system illuminates, and an electric current to a compressor 1 is disconnected preventing the compressor 1 from being actuated. This configuration can prevent the compressor from being burnt out due to a lack of refrigerant.

Title: Image forming device
Inventor: KIMURA KOJI
IPC: G03G15/01
Filed: 1992-06-29
Abstract: PURPOSE: To achieve the prevention of image quality deterioration, which is caused by unsatisfactory attraction, and the secure removal of a jammed paper by allowing the free contact/separation of a conductive drum with/from a transfer drum, by bringing the conductive drum close to the transfer drum only when a transfer material is supplied and attracted to the transfer drum, and by cleaning the roller when a developing device is not close to the conductive roller. CONSTITUTION: When the conductive roller 26 is close to the drum by the action of a spring 3, transfer is carried out. After the transfer, a shaft 5 turns, the conductive roller 26 moves apart from the transfer drum by the action of a cam 6 and comes into contact with a brush 10, and also gears 7 and 8 engage. At this time, because toner images in separate colors are formed in order on an image carrier and developing units move in order toward the conductive roller 26, a motor 9 is not driven and the roller is therefore not cleaned. When the developing device retracts after the development, the motor 9 is driven to cause the brush 10 to come into contact with the conductive roller 26 to clean it.

IPC: F28F1/32
Filed: 1988-08-02
Abstract: PURPOSE:To improve an air thermal transmitting efficiency and restrict a phenomenon of frosting by a method wherein fins are formed into a corrugated shape in which its mountain part and its valley part are alternatively continued in an air flow direction and a height of the mountain part and a projected length against the fin surfaces between the mountain part and the adjoining valley part are specified. CONSTITUTION:Fins in a group of fins are formed into a corrugated form in which its mountain part and valley part are alternatively continuous in an air flowing direction. A height H of the mountain part is within a range of 1mm<=H<=1.5mm and further a projecting length L against the fin surfaces of the valley adjoining to the mountain part is within a range of 2mm<=L<=4.4mm. At the fins 2 of corrugated shape, an air thermal conductivity is higher as compared with other slant surface at a rear part of the mountain top and at a rear part of the valley bottom part of the fins 2. The air peeled off at the mountain top and the valley bottom is readhered and a flow speed at that part is increased and the air flow is disturbed. That is, in order to improve the air thermal conductivity without arranging any louvers or slits in the fin surfaces and increasing a phenomenon of frosting, it is the most effective one to increase the number of mountain top and valley bottom where the air stream passes at the fin surfaces.

Abstract: PURPOSE:To form an image correctly in a photosensitive area except at the seam of a photosensitive belt by counting the length of the deviation of the seam from a stop position, and shifting an exposure start point of time by the length in the next image formation. CONSTITUTION:The endless photosensitive belt 9 formed by laminating a vapor- deposited metallic layer and a photoconductive layer on a transparent sheet rotates while extended among rollers 5-8.
