Title: Focus adjustor
Inventor: MORIZUMI MASAAKI
IPC: G02B7/04
Filed: 1993-11-25
Abstract: PURPOSE:To allow a larger moving value of a focus lens tube without increase in thread pitch by arranging a circular body for angular increment between a cylindrical body and a focus adjustment knob. CONSTITUTION:When a focus adjustment knob 36 is turned by about 300 deg. to a body cylinder 34, the knob 36 comes together with a angular increment ring 38 with a stopper pin 48 engaging a first engaging pawl of the angular increment ring 38 and then, as turned by about 300 deg. integral with the angular increment ring 38, a second engaging pawl of the angular increment ring 38 abuts a protrusion piece part of the body cylinder 34 to regulate the rotation thereof. As a result, the angle of rotation of the knob 36 can be increased to about 600 deg. with the action of the angular increment ring 38, hence becomes almost double of the conventional rotation angle. This allows a larger moving value of a focus lens tube without increase in the thread pitch of the body cylinder 34 and a screw cylinder 44 of the knob 36 and the like.

Title: Method of manufacturing semiconductor device and chemical machine polisher
Inventor: FUSE AKIHIRO
IPC: H01L21/3205
Filed: 1994-11-04
Abstract: PURPOSE: To bury a metal in a connecting hole for flattening the surface of an insulating film using a chemomechanical polishing step comprising a series of processes. CONSTITUTION: An interlayer insulating film 3 is formed on a metallic wiring 2 formed on a semiconductor substrate 1 and after the formation of a connecting hole in the interlayer insulating film 3, a metallic film 6 is formed on the interlayer insulating film 3. This metallic film 6 is polished using an acid polishing solution in a chemomechanical polishing process. In this chemomechanical polishing process, the surface exposed time point of the surface of the interlayer insulating film 3 to the polished surface is detected by the change of revolving torque of a carrier head or the conductivity in the wafer thickness direction to continue the polishing of the metallic film as it is assuming the detection time as the terminal time.  Later, the feeding of the polishing solution is stopped to be substituted for pure water for linsing step and then substituting for alkalic polishing solution for insulating film for polishing the interlayer insulating film 3 for flattening the surface. In the polishing step, the metal 6 buried in the connecting hole 4 is used as the polishing stopper of the interlayer insulating film 3.

Title: Pulse count system for tuner
Inventor: KIDA HIROYUKI
IPC: H03J5/00
Filed: 1989-11-13
Abstract: PURPOSE:To simplify the structure by multiplying the number of pulses per unit time when the number of pulses generated in a pulse switch is within a range of multiplication and displaying a numeral on a screen of a display section. CONSTITUTION:The number of pulses per a prescribed time generated in a pulse switch 16 is counted by a count section. The count section decides whether or not the result of count is within a prescribed multiple range. As a result of decision, it is decided that the count is within the multiple range, the count section multiplies the number of pulses per a prescribed time with a prescribed multiple rate and a numeral is displayed on the screen of a display section 14 in response to the number of pulses per a prescribed time. Thus, even when the numeral displayed on the screen of the display section 14 is largely changed, for example, the display number is changed by turning the pulse switch quickly. Thus, the structure is simplified.

Title: Device for controlling operation of refrigerating apparatus
Inventor: SAWAI KATSUYUKI
IPC: F25B1/00
Filed: 1991-11-12
Abstract: PURPOSE:To prevent a refrigerating apparatus, when an overload activates a protective device, from discontinuation of the operation at the time that the delivery of the compressor is increasing during pull-down control. CONSTITUTION:A refrigerant circuit is equipped with variable capacity type compressors 2a, 3a, evaporators 2i, 3i, and motor-operated expansion valves EV1, EV2. A protective device 41 is provided. In the operation, by using a means for pull-down control 45 the compressors 2a, 3a are controlled at a low delivery and a specified value is set for the maximum valve opening of the motor-operated expansion valves EV1, EV2, whereas, when the temperature of the controlled space falls below a specified point, a capacity-increasing means 46 acts to shift the control of the compressors 2a, 3a to a high capacity. When the protective device 41 has been activated, a means for abnormal time control 47 acts to decrease the valve opening of the motor-operated expansion valves EV1, EV2 by a certain degree from the specified value and then makes the apparatus resume the operation. It also befits the operation to store in a memory two alteration patterns, one for larger openings than the other and both designed to decrease the valve opening of the motor-operated expansion valves EV1, EV2 the more as the load approaches an overloaded condition, so as to shift the use of the alteration patterns from the larger to the smaller when the capacity of the compressors 2a, 3a is increasing.

Filed: 1987-11-26
Abstract: PURPOSE:To uniformly supply fuel gas to a catalytic layer with a simple structure by keeping the catalytic layer away from a heat insulating material having a heater on combustion. CONSTITUTION:When a catalytic combustion in which fuel gas reacts in a catalyst layer 12 starts and the temperature of the catalyst layer 12 rises to, for instance, 400-600 deg.C, a motor 17 as a driving means is reversed through a controlling means 24 by an electrical signal from a temperature sensing means 23 so as to move a heat insulating material 14 having a preheater 14 away from the catalyst layer 12 to form a space 27 between the catalytic layer 12 and heat insulating material 14. Under the condition, the thermal resistance further increases due to the space, and there is no heat radiation to the heat insulating material 14. Further, due to the separation of the preheater 14 from the catalyst layer 12, the flow resistance of fuel gas flowing through a supply pipe 20-a fuel supply part 19-the heat insulating material 14-the space 27-the catalyst layer 12 repeats the rise and fall in value, the fuel gas can be uniformly supplied to the catalytic layer 12, and the clean combustion is ensured on steady burning.

Abstract: PURPOSE:To improve quality stability and reliability of a magnetic disk device by mixing many regions each having high wettability and regions each having low wettability for lubricant on a surface, and adsorbing the lubricant in the regions each having the high wettability. CONSTITUTION:A lubrication surface 1 such as a magnetic disk surface in plane (100) is composed of regions 11 each having high wettability and regions 12 each having low wettability for lubricant 2. The lubricant 2 becomes a state such that many balls are formed on the surface 11 having high wettability on the surface 11 by means of its surface tension, and when a force is received, they alter their direction like fluctuations of seaweed. Further, when a solid surface such as a magnetic head 110 is brought into contact with the surface, the balls of the lubricant 2 hydraulically become, due to the intermediary of the regions 12 each having the low wettability, a positive pressure by means of surface tension, thereby preventing approach and contact of both surfaces such as the disk 100 and a magnetic head 110. Thus, performance, quality and reliability of a magnetic disk device are improved.

Title: Control device for composite cooker
Inventor: SUMIYOSHI SHINICHIRO
IPC: H05B11/00
Filed: 1995-11-16
Abstract: PROBLEM TO BE SOLVED: To perform a highly safe and reliable control by effectively throttling the conduction time of a switching element in starting of an inverter and when the connection between the detecting winding of a booster transformer and a printed board is insufficient to protect a circuit. SOLUTION: An inverter circuit 102 supplies a high frequency power to a microwave heating magnetron 105. A detecting winding 107 detects an output of constant voltage level proportional to the high voltage output of a booster transformer 104 for applying a high voltage to the magnetron 105. When the detected output of the detecting winding 107 is a prescribed value formed by a first constant voltage diode 109 or more (it occurs in the starting of the magnetron), a control is performed so as to shorten the conduction time. When the detected output is less than the prescribed value formed by a second contact voltage diode 110 which is smaller than the first prescribed value, the current- carrying time is throttled to protect the circuit. According to this constitution, a highly safe and reliable control can be performed.
