Title: Manufacture of shadow mask and device therefor
Inventor: NISHIKAWA HIROSHI
IPC: H01J9/14
Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To reduce the machining time and process of a shadow mask to enhance production efficiency by punching a steel plate from a roll using a rotary press consisting of male and female drums, and cutting it after processes of resist application, exposure, and etching. SOLUTION: A steel plate 2 fed from a roll 2a is sandwiched and passed between the rotating, drum-shaped, blade-equipped male and female dies of a rotary press 7 to form continuous slits in a shadow mask. Next, a resist is applied to one side of the steel plate 2 by a resist application device 8 and baked by an exposure device 9, and burrs produced by punching are removed by an etching device 10. Next, the steel plate 2, from which a film of the resist is removed by a resist peeling device 11, is cut by a cutting press 5 to complete the shadow mask. Thus the slits are machined using the press 7, so the shadow mask can be manufactured with high efficiency while reducing the machining time and process.

Title: Seal coupling device
Inventor: IWABUCHI TOSHIAKI
IPC: F16L19/03
Filed: 1991-09-04
Abstract: PURPOSE:To provide a seal coupling device which eliminates any partial bump of a gasket attributable to the spillage of a sealing point, and no fear of falling this gasket off. CONSTITUTION:A ring recess 12 is installed in at least either surface of both end faces of a body 2 and a sleeve 1. A first ring projection 13 and a second ring projection 14 are formed on both inner and outer circumferences of the ring recess 12 at this end face. When a seal coupling is constituted, a ring elastic retainer 15 holding a gasket G on the inner circumferential surface is fitted in the first ring projection 13 in utilizing its elasticity, and since screwing between a female nut 3 and the body 2 takes place, the gasket G will in no case fall off at time of installation. With the nut 3 clamped tight, the gasket G is compressed and tries to expand diametrically, but the elastic retainer 15 is also expanding diametrically so as to fill up a gap with the second ring projection 14, thus any slippage in sealing point is not produced at all.

Title: Method for measuring amount of bacterium cell
Inventor: YANO TAKUO
IPC: G01N21/49
Filed: 1990-11-08
Abstract: PURPOSE:To perform the subject measurement at a low cost in a short time by adding a diluent such as water or physiological saline solution to a sample taken out from a culture device and simultaneously measuring the turbidity of the diluted solution. CONSTITUTION:The passage of a diluting measurement device 4 is preliminarily cleansed and evacuated. A culture solution is injected into the device 4 through a sampling pipe 2 with the culture solution-sampling pump 3 of a culture device 1. Water or physiological saline solution is batchwisely injected into the device 4 with a diluent- injecting pump 9 to dilute the injected culture solution. While measuring the turbidity of the fluid in a flow cell 7a with a turbidity meter 7, the diluted solution is circulated in the circulation route 5 with a circulation pump 6. Even when the route 5 is filled with the diluted solution, the diluent is continuously injected, and the excessive amount of the solution is discharged from a solution-discharging opening 5c. When the concentration of the diluted solution is gradually lowered and reaches a range capable of being stably measured with the turbidity meter 7, the pump 9 is stopped and the turbidity is measured. The amount of bacterial cells in the culture solution is determined from a preliminarily prepared calibration curve showing the relation between the turbidity and the amount of the bacterial cells.

Title: Method and device for controlling load
Inventor: FISCHER WERNER
IPC: H02J1/00
Filed: 1997-11-06
Abstract: PROBLEM TO BE SOLVED: To reduce the power loss of a power transistor by controlling a first switching means connected in parallel with a control means additionally to the control means in a first phase and, in addition, a second switching means against the control means also in a third phase. SOLUTION: A resistor 150 is selected so that most of a current can flow through a switching means 140 and the resistor 150 and only a small amount of the current can flow through a control means 110. This is realized by making the resistance value of a branch composed of the means 150 and 140 smaller than that of the control means 110 during a period from a point of time t1 to another point of time t2. This means that the branch composed of the means 150 and 140 consumes most of the power loss of a power transistor. In addition, a resistor 155 is selected so that most of the current can flow through a switching means 145 and the resistor 155 from a point of time t4.

Title: Plasma apparatus
Inventor: OKU KOJI
IPC: H01L21/205
Filed: 1994-12-08
Abstract: PURPOSE: To compensate the difference of loss differing based on the difference of length of electricity supplying cables and the types of rectifying circuits and provide stable plasma by detecting effective transmitted electric power supplied to a plasma chamber by an electric power detecting circuit and carrying out negative feedback of the detected value as an electric power detected value to a high frequency electric power source. CONSTITUTION: An electric power detecting circuit 40 to detect effective transmitted electric power to a plasma chamber 20 detects high frequency electric current flowing through a rectifying circuit 30 by a current transformer 41. The detected current is transformed into voltage through a terminal resistor 42 and the voltage of a high frequency output sent out through the rectifying circuit 30 is detected by dividing the voltage by voltage dividing resistors 43, 44. Detected current of the high frequency output detected by the current transformer 41 and current of a local electric power source 45 are multiplied by a double balanced mixer 46a to carry out frequency mixing and the divided voltage and the voltage of the electric power source 45 are multiplied by a mixer 46b to carry out mixing.  After passing a high band interfereing filter 47, the outputs of the mixer 46a, 46b are multiplied by a multiplier 48 and converted into low frequency by a low ban filter 49 and thus high frequency electric power can be detected. As effective transmitted electric power value, the detected value is turned back to the electric power source 3 side by negative feedback.
