Title: Lighting device
Inventor: MASAKI KAZUMI
IPC: H05B39/04
Filed: 1989-07-27
Abstract: PURPOSE:To obtain a natural light optimum to a lighting of an excellent coloration with the color temperature about 2900K or more from an argon tube for a long period by applying a voltage exceeding the rating to the argon the to light. CONSTITUTION:At the AC side of a rectifier circuit which consists of a bridge rectifier D and a smoothing capacitor C, an alternating current power source AC is connected through an arc discharge current limiting circuit 1, and at the DC side of the bridge rectifier D, an argon lamp AL is connected through a rush current limiting circuit 2. In this case, to the argon lamp AL, a DC voltage exceeding its rating, a DC voltage of about 105-125% of the rating, for example, is applied to light. As a result, a natural light of an excellent coloration with no flicker, with the color temperature about 2,900K or more, can be obtained from the argon lamp AL for a long period.

Title: Semiconductor device for switching
Inventor: SHIGEKANE TOSHIO
IPC: H03K17/567
Filed: 1984-09-18
Abstract: PURPOSE:To attain control with a simple rectangular wave input signal voltage by providing a conduction blocking means to a bipolar transistor (TR) and an FET connected in parallel and giving a trapezoidal waveform drive voltage to them. CONSTITUTION:An FETQ2 is turned on at a point P1 when a trapezoidal input signal voltage Vi is equal to Vo (threshold voltage of the G of the FETQ2) from a terminal A. Then a TRQ1 is turned on at a point P2 with Vi=Vz (Zener voltage of a ZD forming a conduction block means). Further, the TRQ1 is turned off after a point P3 with Vi<Vz and the FETQ2 is turned off after a point P4 with Vi<Vo. Thus, the FETQ2 is turned on always earlier than the TRQ1 and turned on later. The trapezoidal waveform input signal is generated from a rectangular wave signal by using a capacitor. Thus, the semiconductor device is controlled with a simple rectangular wave input signal voltage.

Abstract: PURPOSE:To increase package density by dividing the surface of an IC into small recessed blocks with thick metal or organic films. CONSTITUTION:Circuit elements are formed on a semiconductor substrate 1, and electrode pads 3 are formed on an insulating film 2. Further, a part 5 corresponding to the power supply wiring is thickened by means of gold plating etc. At that time, patterning is carried out so that the IC surface is divided into small recessed blocks 6. This patterned plated layer is formed to extend the electrode pad 3 onto the power supply wiring, and the thickness thereof is caused to be not less than that of the electrode pad and capable of maintaining the internal space during the packaging minimum, and the thickness in the range of 30-100mum is suitable. When an alpha-ray shielding film is coated on the surface after dicing and bonding in this IC structure, because the surface tension is scattered to every small recessed block, the thickness of the coated film can be made nearly uniform and thin, and the swelling up of the alpha-ray shielding film can be eliminated and miniaturization of a TABIC package can be achieved.

IPC: B41J2/02
Filed: 1985-09-06
Abstract: PURPOSE:To make it possible to perform good recording by stably generating small size ink particles even when a recording apparatus is operated under a high temp. environment, by specifying the initial values of the viscosity and surface tension of ink to be used. CONSTITUTION:The initial values of the viscosity N and/or surface tension T of ink to be used are set so that the viscosity N and surface tension T of the ink at the max. temp. (t) of the ink injected from a nozzle when a recording apparatus is a recording state are on a small size ink particles stability forming boundary approximated by N<n>XT<m> (wherein n and m are a positive constant) or above. The finely pulverizing characteristic of a small size ink particle largely depends an the physical properties of ink, such as the viscosity and surface tension of the ink. When the physical properties of the ink are present in regions A, B, stable recording can be performed but, when they enter a region C, no stable recording can be performed. The boundary line of the regions B, C is a microdot particle stability forming boundary line. This curve can be approximated by N X T<m> = K (wherein K is a positive constant) and determined by a particle forming condition.

The pressurizing balloon 11 is made of a flexible rubber and, therefore, executes uniform pressurization so as to enclose the optical fiber 2 in a wide range. Since the optical fiber 2 intrudes closely into the V-grooves 3 of the optical device 1, the alignment of the optical axis of the optical fiber 2 and the optical axis of the optical device 1 is easily and rapidly executed. The alignment is completed when the optical fiber 2 is adhered into the V-groove and is cured.

Title: Shape measuring method for rolled strip and device thereof
Inventor: TAWARA YUJI
IPC: B21C51/00
Filed: 1993-07-14
Abstract: PURPOSE:To improve the yield of quality control by analyzing the vibration frequency c>f the displacement of a strip traveled in a tensile state. CONSTITUTION:Rollers 2, 3 are arranged at a fixed distance, and a fixed tensile state is applied to a strip S passing on them. A plurality of displacement sensors 1 are provided across the strip nearly at the center between the rollers 2, 3. The displacement of the strip S at each portion in the width direction is detected in the form of vibration, and a different detected value by each sensor 1 is transferred to an analyzing device. The vibration frequency is analyzed here to obtain an inherent distribution curve. The peak value and the frequency with a large band width are extracted as the representative vibration frequency, and the inherent tension at each portion is calculated. The distribution of tension is related with the potentially hidden shape defect at the corresponding position, the distribution of tension is fed back to a rolling device as the quality information to improve the shape, thereby the occurrence of the shape defect is minimized.

Title: Switching mode converter
Inventor: SUTEFUAN FURANSHISU NIYUUTON
IPC: H02J1/00
Filed: 1993-07-14
Abstract: PURPOSE: To recover the output voltage smoothly from instantaneous drop-out of a feeder line by connecting a switch mode converter with a soft start circuit producing a desired output through switching control of the switch mode converter. CONSTITUTION: Upon receiving drop-out of an input line VIN, a drop-out detection circuit 391 delivers a low level signal to a PWM control circuit 387 which is thereby turned off and the voltage of a capacitor 115 drops as the output voltage VOUT drops. When the voltage on the input line VIN is recovered, a line drop-out detection circuit 391 delivers a high level signal for resetting the PWM control circuit 387 to turn off state thus increasing the output voltage VOUT to a normal level. The recovery rate can be altered by adjusting the value of a capacitor 131 thereby optimizing the soft start performance or the trouble recovery performance.
