Title: Device for processing photosensitive material
Inventor: OBA HISAO
IPC: G03D5/04
Filed: 1989-09-20
Abstract: PURPOSE:To lessen the change in the concn. in 2nd and subsequent processing tanks by operating a supplying means to supply the processing liquid lower in concn. than the concn. of the processing into a 1st processing tank and supplying a replenishing liquid of the volume proportional thereto into the 1st processing tank when the electrical conductivity of the processing in the 1st processing tank attains a prescribed value. CONSTITUTION:The degree of fatigue of the developing soln. when plural sheets of PS plates 12 are processed in the 1st developing tank 14 is detected as the area of the PS plates 12 by a detector 174 and is computed by a processing and replenishing controller 164 to replenish the developing soln. The operation time of a stock soln. supplying pump 132 and a feed water pump 136 is determined in such a manner to determine the amt. of the replenishment according to the area of the PS plates. The electrical conductivity of the developing soln. is kept detected by an electrical conductivity detector 96 as well and the feed water pump 92 is operated by an electrical conductivity replenishing controller 176 to supply the water to the tank 14 when the electrical conductivity attains the prescribed value or above by thickening. The rate of steam generation in the 2nd developing tank 18 and a finisher tank 24 is measured as well and the pumps 136 and 168 are operated.

Title: Method for controlling expansion valve in vapor-compression refrigerating apparatus
Inventor: KAWAI TAKESHI
IPC: F25B1/00
Filed: 1992-08-21
Abstract: PURPOSE:To carry out the stabilized control irrespective of the length of the piping for refrigerant, which may differs depending on the location of the installation, by a method wherein the length of the refrigerant piping is estimated by analogy from a change in the temperature condition inside the evaporator and an optimal control parameter corresponding to the estimated length of the refrigerant piping is set in the controller for the control of the expansion valve. CONSTITUTION:Temperature detectors 9, 10 detect the temperatures at points (a), (b) inside an evaporator 1 and output temperature detection signals (d1), (d2) respectively. To make the difference between the temperature detection signals (d1), (d2) assume a preset value, a controller 11 obtains a manipulation variable based on a control parameter and outputs the amount. For example, when the temperature detection signal (d1) starts to decline, the controller 11 acts to control the expansion valve 4 toward recovery of the previous stabilized conditions but the tendencies that the temperature detection signals (d1), (d2) thereafter take vary with the time response characteristics which depend on the length of the refrigerant piping. Therefore, the length of the piping is estimated at an inference unit 13 and, for example, a PDI parameter is set as a control parameter.

IPC: H01L21/68
Filed: 1985-10-31
Abstract: PURPOSE:To reduce an equipment cost, to prevent damages of wafers and to improve a yield rate and quality, by engaging an intermediate buffer, wherein the wafers that are pushed from one holding part are temporarily accommodated and held, with a boat holding part, and moving the buffer up and down. CONSTITUTION:A cassette 102 accommodating wafers is mounted on a cassette holding table 101. The cassette is pushed by using a pushing mechanism 103. The wafers are slidden and moved to an intermediate buffer 106. Then, a movable table 105 is moved, and cut-out parts 110a and 111a of guides 110 and 111 are engaged with supporting posts of a vertical boat 114. Then, the guide parts 110 and 111 are brought closer. The wafers are slidden and moved in the holding grooves in the guides 110 and 111 by the operation of a pushing mechanism 107. The height of the groove 110a is selected so that the wafer is not contacted with the inner surface of the holding grooves, which are formed in the supporting posts of the boat 114. Therefore, even if the wafer is pushed, it is only slidden in the guides 110 and 111 and is not contacted with the boat directly, and silicon chips and the like are not yielded.

Title: Pressure-fillable explosion-proof aerosol valve
Inventor: KITABAYASHI SEIICHI
IPC: F17C13/12
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To enable high pressure gas to be easily filled and discharged by pushing down an upper face of a stem rubber for forming a flow path in a reverse direction to that at the time of filling and discharging outside an internal pressure in a used injection container. SOLUTION: A longitudinal groove 13 on a peripheral side face of a swollen head is connected with a space of a circular protrusion 16 formed on a top plate peripheral part. Thus at the time of filling high pressure gas from a slit, an upper face of a stem rubber 4 is pushed down by a pressure of the high pressure gas to be filled, whereby the high pressure gas flows between the upper face of the stem rubber 4 and a rear face of a mountain cap which are normally closed to form a flow path for the gas. When a used injection container is put in an incinerator, the upper face of the stem rubber 4 is pushed down by the internal pressure of the high pressure gas. The gas passes through the flow path same as that at the time of filling the high pressure gas, wherein a positional relation between a high pressure side and a low pressure side is inverted.  The flow path is formed in a reverse direction to that at the time of filling, and the internal pressure which has abnormally risen is discharged outside, so that explosion of the used aerosol injection container can be prevented.

Abstract: PURPOSE:To manufacture a photocoupler stably and at a low cost by a method wherein it is sealed with a light-transmitting resin by a casting operation in order to prevent a thin burr from being produced caused by leakage of the resin from a plastic case. CONSTITUTION:Lead frames 3 where a semiconductor light-emitting device 1 and a semiconductor photodetector 2 are installed are built in a plastic case 4; a stopper 5 for resin outflow prevention use is installed into a groove of the case into which the lead frames 3 are put. A resin 6 is injected into the plastic case 4 in such a way that it covers the lead frames 3. After that, the resin 6 is hardened at a high temperature. In addition, if the stopper 5 for resin outflow prevention use and the plastic case 4 are removed, the internal resin is formed. After that, if the resin 6 is covered with a light-shielding resin, a photocoupler is completed. A methylpentane polymer or the like to be used to manufacture a lamp can be used as a material for the plastic case. In addition, as the resin for a casting operation, a material where a filler and silicone rubber for deterioration prevention use of a light-emitting device are mixed with a resin to be used to manufacture the lamp can be used.

Title: Optical pickup device
Inventor: TAKEDA TADASHI
IPC: G11B7/1275
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To provide a multi-light source type optical pickup device having low cost and high general applicability. SOLUTION: A dual light source type optical pickup device is equipped with a light source unit which incorporates a first laser light source 35 and a common photodetector 36, and with an individual light source 4 which is a second laser light source, the laser beam from each light source being guided to a common optical path L by a prism 5 for synthesizing optical paths. Return light from an optical disk 10 is passed through the prism 5 and received by the common photodetector 36 inside the light source unit 3. Diffraction elements 32, 42 for forming three beams are individually capable of rotary adjustment. With the photodetector commonly used, the device can be manufactured at low cost.  Also, both laser beams are free from optical axis deviation; hence, the characteristical changes in the optical system incident to the movement of the objective lens become symmetrical to the center optical axis, dispensing with a special compensating circuit. In addition, since diffraction gratings for forming three beams are individually adjustable, a multi-light source type optical pickup device can be realized that is applicable to various types of systems.
