Patent JP-S59157434-A (JP)
Title: Method of controlling temperature of supply hot water in gas instantaneous water heating apparatus
Inventor: TSUTSUI OSAMU
IPC: F24H1/10
Filed: 1983-02-22
Abstract: PURPOSE:To prevent offset and improve a time required for starting hot water supply regardless of the temperature set stages by determining proportional gains for respective temperature set stages. CONSTITUTION:In a hot water supplying machine in which the set temperature is switched to four stages, ''tepid'' (35 deg.C), ''shower'' (42 deg.C), ''slightly hot'' (60 deg.C) and ''hot'' (80 deg.C), for example, the water supply temperature is set in the range of 5-25 deg.C, and the fine adjustment is set at + or -5 deg.C, when proportional gains are obtained from experiments under the worst conditions of set temperatures, that is, conditions of the maximum set temperature and the minimum temperature, and the proportional gains are set in ''hot''alpha1, a ''tepid''alpha2, ''shower''alpha3 and ''slightly hot''alpha4. In this case, alpha2>alpha3>alpha4>alpha1. That is, in the case of alpha2, the starting becomes faster as compared with the case of alpha1 because when the fed forward gas quantity is raised by the feed back, it starts from a point where the gas quantity initially imparted is large, as shown in the graph. Accordingly, in the case where the temperature set stage is ''hot'' and in the case where the temperature set stage is ''tepid'' as well, the starting time becomes faster and the offset becomes small.

Title: Cleaning up device and process of semiconductor substrate
Inventor: SADAMORI MASAAKI
IPC: H01L21/304
Filed: 1990-02-07
Abstract: PURPOSE:To enable the cleaning up effect of semiconductor substrate to be enhanced by a method wherein retaining cases internally retaining the semiconductor substrates are vertically inserted into a cleaning up vessle while the semiconductor substrates are alternately advanced and retreated in the vertical direction by retainers for mutually positioning adjacent two semiconductor substrates in the vertical direction. CONSTITUTION:When retaining cases 35 internally retaining wafers 36 are vertically inserted into a cleaning up vessel 31 from an acid etching vessel (not shown in figure), mutually adjacent two wafers 36 can be positioned respectively in the vertical direction by retainers 39. At this time, when a crankshaft 37 is rotated by a motor 38, mutually adjacent two retainers 39 are alternately advanced and retreated in the vertical direction. Accordingly, the parallel interval between mutually adjacent two wafers 36 can be widened as well as advanced and retreated in the vertical direction. In such a constitution, the parallel interval between wafers 36 in the retaining cases 35 need not be widened by positioning mutually adjacent wafers 36 in the vertical direction during the cleaning up process.

Abstract: PURPOSE: To prevent blade distortion following temperature change by having reinforcement on the upstream side surface of each blade, and by providing a plurality of longitudinally separated holes at its side part so that a set of holes at one side part are displaced from a set of holes at the other side part. CONSTITUTION: Each blade 17 has a reinforcement 36 on the upstream side surface when the damper is closed, each reinforcement 36 is an assembly which has a flat central part 37 and flat side parts 38, and the side parts 38 are inclined near the both edges toward the blade 17 to float the central part 37. A set of holes 40, of which the holes at one side part 38 are displaced from a set of holes at the other side part, are provided at each side part 38. In this structure, hot gas flow in starting of a turbine collides to a part of each blade 17 surrounding the reinforcement 36, and flows as turbulence in each reinforcement 36 as well. Therefore, all parts of the blade 17 overlapping under the reinforcement 36 are heated to prevent undesired distortion of the blade.

IPC: G01J1/42
Filed: 1983-02-23
Abstract: PURPOSE:To remove unfavorable effects resulting from the dislocation and fluctuation of an optical axis by dividing a photodetector in equal parts with plural lines passing through the center of a photodetecting surface, and placing the photodetector on a jogging stand which is movable on a plane normal to the optical axis. CONSTITUTION:The photodetecting surface of a photodetector 4 is divided in equal parts 4a-4d. The outputs of the small pieces 4a-4d are supplied respectively to comparators 14a-14d through each amplifier 7a-7d. Then a jogging stand 16, on which the photodetector 4 is placed, is controlled by a control circuit 17 so that the comparative outputs from each comparator 14a-14d may become equal. Thus the laser light spot is caught always at the central part of the photodetector 4.

IPC: C02F3/30
Filed: 1985-02-18
Abstract: PURPOSE:To execute the decomposition treatment of org. sewage effectively by introducing gaseous oxygen into a reaction vessel into which the org. sewage and activated sludge are charged, subjecting the sewage and sludge to anaerobic digestion therein, generating the specific oxidation-reduction potential and con trolling the inside of the reaction vessel to a specific temp. CONSTITUTION:The gaseous oxygen is introduced through a pipe 17 into the perfect mixing type or extrusion flow type reaction vessel 16 into which the nitrogen-contg. org. sewage 15 and activated sludge 25 are charged. The BOD components adsorbed to the sludge formed in the vessel 16 are subjected to the anaerobic digestion. The temp. in the vessel 16 is controlled to attain 40-55 deg.C while the supply rate of the gaseous oxygen to the vessel 16 is so controlled as to produce alternately in time or position the operation section for controlling the oxidation-reduction potential in the vessel 16 to -150-0mV and the operating section for controlling the same to <=-150mV. The amt. of the sludge to be formed in the treatment of the nitrogen-contg. org. sewage is thus decreased and the effective decomposition treatment is made possible.

Title: Tape recorder with queue/review mode
Inventor: MASUDA HIROAKI
IPC: G11B15/087
Filed: 1994-02-28
Abstract: PURPOSE:To improve operability at the time of a queue mode or a review mode. CONSTITUTION:At the time of setting the queue mode, a fast-forwarding setting lever 12 is pushed up in the state of a reproduction mode, and a protrusion 25 of a seventh opening 18C of a first slider 18 is pressed to a right side, and the first slider 18 is moved to the right side. Thus, the protrusion 23 of a fifth opening 18A is off from an restraint part 3B of a reproducing lever 3, and the lock of the reproducing lever 3 is released. Further, at this time, the restraint part 12B of the fast-forwarding lever 12 presses a projection part 21 of a third opening 17C of a second slider 17 to a left side, and the second slider 17 is moved to the left side. Then, the protrusion 19 of a first opening 17A goes out a little downward the restraint part 3B, and the restraint part 3B is engaged with the protrusion 19, and the reproducing lever 3 is locked. Thus, a magnetic head l is held to a position lowering by a prescribed size from at the time of a reproducing mode, and mutual friction force is reduced. In such a case, the operability is improved since no necessity continuing to depress the fast-forwarding lever 12 exists.

Filed: 1987-02-12
Abstract: PURPOSE:To produce a simple-structure substrate capable of easy peel-off of bumps by a method wherein a comb-shaped conductor is allowed to be partly exposed from an insulating film and a bump is formed on the exposed portion. CONSTITUTION:On a platform 2 built of a heat-resistant glass or ceramic organic material, a comb-shaped conductive layer 11 is formed with its teeth protruding into a region planned for the formation of a bump. An opening 13 in an insulating film 12 attached thereto is so formed as to cross two sides of the conductive layer 11. A bump is to be formed on a conductive layer 11A exposed in the opening 13 in the insulating film 12. In such a design, the size of the conductive layer formed outside the opening 13 for bump formation is small and, further, such in the region surrounded by the opening 13 is still smaller. This design keeps at the minimum the generation of undesired bumps to be formed in the insulating film 12 on the conductive layer 11 attributable to pinholes or cracks.
