Abstract: PURPOSE: To completely eliminate the influence by ion substance by applying unsaturated, combined and contained organo polysiloxin on the surface of a semiconductor device wherein ultraviolet rays is applied for hardening.  
     CONSTITUTION: After applying unsaturated, combined and contained organo polysiloxin or a composite consists of the above and organo peroxide to a part or all of the semiconductor device, the organo polysiloxin is hardened by applying the ultraviolet rays to obtain a hardened film of the siloxin on the surface of the semiconductor device. In this case, it is necessary to use the ultraviolet rays having the wave length of 100 through 300nm because a sensitizer is necessary if the wave length is 300nm or more. In this way, such treatments as mixing, defoaming are unnecessary through the above treatments are required if a multi-ingredient is used, and it is absolutely unnecessary to consider the influence by ion substance as no hardening medicine is used.

Title: Slide-contact member
Inventor: KONUKI TORU
IPC: F16C33/14
Filed: 1999-02-15
Abstract: PROBLEM TO BE SOLVED: To prevent seizure and abrasion, even using the lubricating oil having low viscosity by forming plural recessed parts, having a specified area ratio and a specified equivalent diameter of circle or more on a sliding surface, and forming a tapered edge part having a specified grade of slope with respect to the sliding surface so as to be converged to the sliding surface on an edge of the recessed parts. SOLUTION: Basically, a tapered part 3 is formed so as to obtain the maximum sagging (l1) at each edge part of plural oil holding recessed parts 2 formed on the sliding surface of a slide-contact member. High load resistant ability of an oil film can be obtained at 0.1-3.0 μm of taper grade. When the area ratio of the recessed part less than 2%, sufficient effect cannot be obtained, and when it is more than 40%, since the real bearing is increased, the seizure resistance is lowered. When the dimension of one member exceeds 150 μm, oil pressure effect cannot be obtained, and the seizure resistance is lowered. When forming the recessed parts on the sliding surface, in order to obtain the set taper grade, the control of the side edge quantity is necessary, and corrosion speed can be restricted to 2-10 μ/min so as to obtain the taper grade at 0.1-3.0 μm.

Title: Manufacture of bulb
Inventor: TSUZUKI SHINGO
IPC: H01J9/32
Filed: 1987-02-20
Abstract: PURPOSE:To prevent oxidation of an electrode by inserting an exhaustion pipe in the vicinity of an electrode and spraying an inert gas on the electrode and simultaneously heating/narrowing a glass bulb opening end so that the opening end is narrowed approximately in the same dimension as an outer diameter of the exhaustion pipe and then extracting the exhaustion pipe to fuse the end of exhaustion pipe with the narrowed part. CONSTITUTION:An inactive gas is always sprayed on an electrode 3 from an exhaustion pipe 8 which is inserted in the vicinity of the electrode 3 from a glass bulb opening end 1 which is on a sealing side of the glass bulb. Therefore, even if the glass bulb opening end 1 is heated/fused by a combustion gas or the like so as to be narrowed, the electrode 3 is not oxidized and it is cooled by the spraying of the inert gas so that its temperature does not rise. At that time when the glass bulb opening end 1 is narrowed approximately in the same dimension as an outer diameter of the exhaustion pipe 8, the exhaustion pipe 8 is extracted and then it is fused and connected with the glass bulb 2. Thus, oxidation due to heating in the electrode can be prevented.

Filed: 1984-02-27
Abstract: PURPOSE:To eliminate the generation of jitters in a video signal by controlling the reading from a memory circuit by means of a read clock signal, which synchronizes with a synchronizing signal through a frequency selecting circuit for removing jitter components. CONSTITUTION:A signal of a frequency 2fH, synchronizing with a synchronizing signal SSYNC of a horizontal frequency fH can be obtained from a voltage control oscillator 17 and supplied to a phase comparator 19. Although jitters always occurs in the signal SSYNC, jitters will not occur in the signal supplied to the comparator 19 by means of the oscillator 17 owing to a function of a PLL circuit 15 constituting a frequency selecting circuit for removing jitters. Thus a read clock signal CLKR obtained by a voltage control oscillator 13 synchronizes with the signal SSYNC and never has jitters. As a result jitters never occur in a luminance signal Y', color difference signals (R-Y)' and (B-Y)' obtained from a memory circuit 8, and an excellent video signal can be obtained.

IPC: B41J2/36
Filed: 1986-02-20
Abstract: PURPOSE:To achieve a high speed print control and to prevent degradation of print with the ambient temperature, by varying the voltage level to be applied onto respective dots of a print head and controlling the time interval for applying the voltage onto respective dots. CONSTITUTION:A voltage control section 2 for varying the voltage level to be applied onto respective dots 1a, 1a of a print head 1 and a main control section 3 for controlling the voltage control section 2 are provided. In an example (a) showing a voltage hysteresis control of respective dots in the print head 1, nothing is dotted in previous time and the time before the previous time. Consequently, the voltage to be applied onto the dot is controlled by the voltage control section 2 to V1 which is higher than the voltage V2 being employed for printing of dots in the previous time in case of an example (b). It is also true for an example (c). In all cases, the time interval for applying the voltage is T. Since the voltage control section 2 controls the applying voltage according to the using conditions of respective dots in the print head 1, thus varying the potential of the applying voltage and performing a thermal hysteresis control, the applying time of voltage is made constant and a high speed printing can be achieved easily.

Title: Resonant switching power source unit
Inventor: TAKASAGO TOSHIAKI
IPC: H02M3/155
Filed: 1992-02-24
Abstract: PURPOSE:To prevent the malfunction of zero voltage switching by detecting the zero voltage of resonance voltage without using a complicated circuit, in a resonance switching power source unit. CONSTITUTION:Resonance voltage detection pulses are generated by detecting the resonance voltage with a detection circuit 100, and comparing it with reference voltage by a comparator 300. The zero voltage of resonance voltage is detected by delaying the time from the detection point of the pulse until the zero voltage of resonance voltage through a delay circuit 40. Here, by making reference voltage out of the voltage being made by smoothing reference voltage, it is so arranged that the time from the detection point to zero voltage does not change by changing the reference voltage in proportion, even if the amplitude of the resonance voltage changes. Hereby, a delay circuit is made into a simple circuit where the delay time is constant, and also it is so made that high voltage can be used, and that the oscillation voltage occurring after the resonance voltage becomes zero voltage can not be detected, thus malfunction is prevented.
