Filed: 1988-05-30
Abstract: PURPOSE:To simplify the adjustment of a roller guide and to prevent the abnormal wear of the inlet port part of a grinding wheel by constituting the title device by providing a roller guide at the positions of the side part of the grinding wheel and yet of the inlet port side and outlet port side of a work. CONSTITUTION:A roller guide 9 gives the force of not vibrating by press-fitting a work 4 to an adjusting wheel 7 at the time when the work 4 is fed into the R1 part of the adjusting wheel 7 by the spring of a spring, plate spring, etc., and the shape of a roller has the tapered part in which the work 4 is easy to come. For adjusting the roller guide 9 the adjustment of the force press-fitting the work 4 only will do, it is simple and a smooth feeding can be done because the work 4 has the same number of rotations as the grinding time and is led in along the adjusting wheel 7 at the time when the work is led between a grinding grindstone wheel 1 and adjusting wheel 7. Consequently the need for considering the wear of inlet port side guides 8a, 8b is almost eliminated by taking the guide method like this and the abnormal wear of the inlet port part of the grinding wheel 1 can be prevented.

Title: Control method for coated article-baking oven
Inventor: NUMANAMI MASAE
IPC: F27D17/00
Filed: 1980-09-25
Abstract: PURPOSE: To accomplish uniformly baking a coated article in an oven with a saved energy consumption, by detecting the temperature of hot gas afrer combustion, comparting the detected temperature with a preset value, and controlling a heat amount of a heater or a fresh air inflow amount and a hot-discharge amount.  
     CONSTITUTION: Hot gas returned from a furnace chamber 14 through a line 20' is heated with a heater 22. Its temperature is raised by combustion of a solvent with a burner 24. The resultant gas is forcedly circulated with a forcible circulater 26, and fed again through a line 20 into the furnace chamber 14. A temperature detected with a temperature detector 40 located at the downstream side of the burner 24 in a hot gas-treating chamber 16 is compared with a reset value in a comparator 42. If the detected temperature is lower than the preset value, the comparator 42 outputs the first output O1 to enhance the electric conductivity of a current limiter 34 and to enhance a heat amount of the heater 22. If it is higher than the preset value, the comparator 42 outputs the second output O2 to control another current limiter 38 through a controller 44 and to enhance an exhaust amount from a hot gas-discharge line 30. In addition, the rotation number of a motor M2 for the purpose is detected with a detector 46, and a current limiter 36 is controlled through a controller 48 to increase sucking amount into an air inflow line 28.

Filed: 1995-05-02
Abstract: PURPOSE: To reduce an impact sound generated on fitting a spray in a socket and to make sure safety against a leak of a drug by installing a housing containing a drug container as exposing and sealing a pressure accumulating tank on the top portion of the pressure accumulating tank. CONSTITUTION: Inserting a spray A into a socket B, a sensor 110 detects it and transmits a detecting signal to a control unit. Then the control unit makes a high pressure generator 150 operate, compressed air (a) is sent into an upper block, thereby a spray stopping piston 160 is pushed out. Also the controlling unit starts to send compressed air (a) to a closed space of the lower block thereby a compressed air supplying piston 130 is raised upward. Further the controlling unit supplies compressed air (a) to a pressure accumulating tank A1 through a through hole 131 of the compressed air supplying piston 130. Therefore by pulling out the spray A from the socket B and pushing a push bar 181, a compressed air (b) reduced the pressure by a pressure reducing valve 192 flows into a drug container 188 through a pipe 190 for passing compressed air and is discharged from a jet nozzle 184.

Abstract: PURPOSE: To improve leakage current characteristics and resisting pressure characteristics, by inhibiting the formation of the compounds of metal, which makes up a base and an equipotential ring, by building up the base and said ring by the metal, which ionization tendency is smaller than aluminum, in a surface of a semiconductor elment.  
     CONSTITUTION: A base electrode 8 and an emitter electrode 9 are formed to the portions, which are not made up yet, of protective layers 6, 7 consisting of SiO 2  on the upper surfaces of a base region 4 and an emitter region 5 by using metal, which is excellent in adherence properties to a semiconductor element substrate and which ionization tendency is smaller than aluminum. An equipotential ring 10 is built up to portion, which is not formed yet, of the protective layer 6 of a fringe portion of a collector region 3 by using similar metal so as to reach the protective layer 6. Local break-down can be prevented because the formation of compounds with mold materials and moisture can remarkably be suppressed by employing such metal meterials. The extents of a depletion layer in the collector region 3 can moderately be kept.

IPC: E05C7/00
Filed: 1979-10-17
Abstract: A lock catch for doors having holding elements thereon includes a catch housing formed with at least one door-mounted holding element-receiving slot therein. At least one locking lever is pivotably mounted within the catch housing. A spring is positioned within the catch housing to normally bias the locking lever to project into the slot. A first bevelled surface is formed on the locking lever and is engageable by the holding element on the door when the door is closed, such engagement resulting in pivotal movement of the locking lever in a first direction to permit entrance of the holding element into an inner end region of the slot inwardly of the locking lever. A second bevelled surface is formed on the locking lever is engageable by the holding element of the door upon withdrawal of such element from the inner end region of the slot in which it has been locked releasably. Such engagement effects pivotal movement of the locking lever in a second and different direction to permit withdrawal of the holding element from the slot. The spring is so positioned relative to the pivot axis of the locking lever and the bevelled surfaces thereof that the effective lever arm of the locking lever when the first bevelled surface is engaged by the holding element entering the slot is greater than the effective lever arm of the spring acting on the locking lever. Further, the effective lever arm of the spring acting on the locking lever is greater than the effective lever arm of the locking lever when the second bevelled surface is engaged by the holding element during withdrawal of the holding element from the inner end region of the slot.
