Title: Vacuum vapor deposition device for polygon mirror and uniform formation of vacuum vapor deposited film
Inventor: TOKITA AKIO
IPC: G02B26/10
Filed: 1992-03-03
Abstract: PURPOSE:To uniformly form the vacuum vapor deposited film with the vacuum vapor deposition device consisting of a polygon mirror. CONSTITUTION:The rotating speed of a stepping motor is accelerated by changing the frequency of the stepping motor to increase the rotating speed of the polygon mirror in the position where the reflection surface 8a of the polygon mirror 8 is paralleled with an adjusting slit plate 11 by the rotation of the stepping motor. The rotating speed of the stepping motor is so controlled as to be slowed down in the position where the adjacent surfaces, such as reflection surfaces 8b, 8a or 8a, 8c of the polygon mirror face the slit spacing(h), for example, when the adjacent surfaces face the slit spacing (h) at about 60 deg. angle in the case the rotary polyhedral mirror is a hexahedron. The thickness of the vacuum vapor deposited film to be deposited by evaporation on the surface of the polygon mirror by passing the slit spacing (h) of the adjusting slit plate 11 is thus controllable and, therefore, the distribution thereof is made constant.

Title: Boiling bubble pump heater
Inventor: MORI KAZUMI
IPC: F24H1/10
Filed: 1989-04-01
Abstract: PURPOSE:To reduce the temperature variance of discharged hot water down to a fraction of temperature change of feed water even if the change is in the range of 5 to 60 deg.C and also to reduce the operating noise by locally forming a treble pipe with an outer pipe, an inlet pipe and a cover pipe Which covers the upper part of the inlet pipe and is closed at its upper end. CONSTITUTION:As the power is supplied to an electric heater 64, the water which is in contact with the heater 64 in the space between the outer pipe 67 and the inlet pipe 76 is rapidly heated. When part of the water reaches its boiling point, steam bubbles are generated to cause the volume of water to rapidly increase, raising the pressure in the outer pipe 67. As a result, the check valve 66 is opened to force the hot water to flow from the outer pipe 67 to the inlet pipe 73. When steam bubbles rise on account of buoyancy to reach the lower end of the cover pipe 79, the steam bubbles are cooled and condensed by relatively cold water nearby. The pressure in the outer pipe 67 then drops to cause the check valve 66, while the check valve 65 is opened to allow cold water existing in the lower part of the hot water reservoir tank 51 to flow through the inlet pipe 76 into the outer pipe 67.

After that, the dummy cell 202 is located lower than mask pattern data 201 and then the information on location of layout cell data 203 is added to the dummy cell as additional information. Then, the layout cell data 203 is expanded to graphic data 401 having an angle θ501 which is positional information on a memory, to generate graphic data 401. When correcting the layout cell data 203, the positional information of the layout cell data 203 is read out and the graphic data 401 on the dummy cell 202 is deleted.

Title: Signal processing circuit

IPC: H03D1/18
Filed: 1985-04-19
Abstract: PURPOSE:To obtain detection output having good reduced voltage characteristic by providing a diode that becomes a level shifter and a transistor (Tr) that detects variation of voltage drop of a load. CONSTITUTION:A diode D1 for level shifter is provided in a current path of a current mirror circuit by TR Q1, Q2. When an input signal Vin is supplied, reference current I1 flows through Tr Q1 and diode D1 and output current I2 flows in Tr TR Q2, Q4 and a resistance RL. When a power source VCC is at a specified level, TR Q3 becomes off and output voltage is not obtained from TR Q3 and waveform distortion does not appear in detection output V obtained as voltage drop of the resistance RL. When the power source VCC becomes low, distortion is generated in output VA and becomes the state of saturation as amplitude corresponding to reduced voltage is not formed. However, TR Q3 becomes the state of on and output voltage VB corresponding to saturated part of output VA appears in the collector. By adding 2 output VA and VB through amplifiers 1, 3, an output signal Vout in which saturated part is corrected is obtained.
