Patent JP-H02277263-A (JP)
Title: Resistance network
Inventor: IGAWA YASUSHI
IPC: H01L27/04
Filed: 1989-04-18
Abstract: PURPOSE:To obtain a resistance-value ratio whose accuracy is high and whose temperature tracking characteristic is excellent by a method wherein a plurality of resistances formed by connecting a plurality of unit diffusion resistances of an identical shape in series or in parallel are provided via a plurality of conductive members which are formed in an identical process. CONSTITUTION:A plurality of unit diffusion resistances 2, 2', of an identical shape, of a second conductivity type are formed side by side at equal intervals inside a semiconductor substrate of a first conductivity type; a semiconductor process to form an insulating film and to form contact holes 3, 3', 5, 5' is executed. After that, conducting members 4, 4' are formed; a resistance formed by connecting the plurality of unit diffusion resistances 2, 2' in series or in parallel via the members is formed at the same time. Thereby, temperature coefficients of a plurality of resistances become nearly uniform; a temperature tracking characteristic of a resistance-value ratio between the individual resistances becomes good.

Title: Blood pressure monitor
Inventor: MIYAZAKI MAKOTO
IPC: A61B5/022
Filed: 1994-05-12
Abstract: PURPOSE:To provide a blood pressure monitor in which high accuracy in monitoring blood pressure can be obtained without forcing strain on the living body. CONSTITUTION:When the oppressive pressure on the cuff 10 is changed to the pressure value PCH, which has been set at a value lower than the average blood pressure, by the oppressive pressure control means 54, an area/shape ratio RAREA is computed by the area/shape ratio computing means 56 and an abnormal drop of the blood pressure value of the living body is judged based upon the change of the area/shape ratio RAREA by the abnormal drop judging means 58. In this way, as the subject blood pressure monitor effects blood pressure monitoring, utilizing the fact that the change rate of the envelope H showing the change of amplitude of pulse wave following the change of pressure on the cuff 10 changes, at the lower pressure side, in response to the change of the blood pressure value, a high monitoring accuracy can be obtained. Further, as the change rate is obtained by changing the pressure on the cuff 10 within the low pressure range from the atmospheric pressure to the specified pressure value, no strain is forced on the living body.

Title: Electroplating method of carbon fiber bundle
Inventor: YAMADA KOUZOU
IPC: C25D5/56
Filed: 1983-06-02
Abstract: PURPOSE:To plate the surface and inside of a carbon fiber bundle at a uniform film thickness with good productivity by providing plural cathodes in the traveling direction of the carbon fiber bundle and distributing the entire current so as to make each current quantity the same or gradually smaller thereby performing multiple-stage plating. CONSTITUTION:A carbon fiber bundle 4 is electroplated in a plating zone I in a plating bath 9 by conduction of electricity from the 1st cathode 1 via nip rollers 5 on the inlet side. The bundle is then electroplated by the conduction of electricity from the 2nd cathode 2 in a plating zone II via the cathode 1. The bundle 4 is electroplated while such operation is repeated then the bundle is passed through nip rollers 6 on the outlet side and is coiled after rinsing and drying. Then the bundle 4 nearer the outlet side of the plating bath is more plated to have better conductivity. The entire current is therefore distributed in such a way that the current quantity at each cathode is kept within the range of the equation (In is the current quantity on the n-th cathode).

Abstract: PURPOSE:To decrease size and weight by using together boosting switching elements and load control switching elements. CONSTITUTION:A closed circuit consisting of a DC power source 1, a choke coil L1, and switching elements S1 and S3 or S2 and S4 is formed and energy is stored in the choke coil L1. When the switching element S3 or S4 is turned off, the energy in the choke coil L1 is supplied to a load 2. When the switching elements S1 and S4 are turned on, the switching element S3 connected to the switching element S1 in series is turned on and off with a high frequency. In this time, when the switching element S3 is turned on, energy is stored in the choke coil L1 and, when the switching element S3 is turned off, the energy in the choke coil L1 is supplied to the load 2. When the switching elements S2 and S3 are turned on, the switching element S4 is turned on and off with a high frequency for the same operation as described above.

Title: Exposure method ad aligner
Inventor: TSUMORI TOSHIRO
IPC: H01L21/30
Filed: 1988-04-21
Abstract: PURPOSE:To prevent bad influence on the optical system of an aligner due to temperature rise of a lens caused by exposure, by intermittently repeating exposure several times to attain necessary exposure on the same part. CONSTITUTION:Light 2 projected from a light source 1 is converged by a condenser lens 3; a reticle, on which a specified pattern is formed, is irradiated with the above light; the light transmitted through the reticle 4 forms an image on a semiconductor wafer 6 by a reduction lens 5. That is, a pattern on the reticle 4 is subjected to demagnification projection on the semiconductor wafer 6, and exposure is performed. For example, exposure of t1=0.5sec is repeated four times by interposing an exposure interruption of t2=0.5, thereby attaining necessary exposure of 2sec. Exposure is intermittently repeated, in this manner, by interposing an interruption interval. Thereby, bad influence on the optical system of an aligner due to temperature rise of a lens caused by exposure can be prevented.

Title: Plate-writing recording device
Inventor: OCHIAI TOSHIHIKO
IPC: B43L1/04
Filed: 1986-04-28
Abstract: PURPOSE:To prevent an image from being disordered when drawn on a writing medium and to eliminate hindrance to the cleaning of a coloring material sticking on a recording medium by arranging a plane elastic support member on the reverse surface side of the recording medium. CONSTITUTION:The plane elastic support member 31 is arranged on the display part back side of the recording medium 1, so when an image is drawn on the writing medium 16 with a felt pen 29, the writing medium 16, the recording medium 1, and the surface elastic layer 31a of the elastic support member 31 all deform. Consequently, the drawing pressure of the felt pen 29 is absorbed by the surface elastic layer 31a and the reverse surface part of the writing medium 16 is neither pressed nor rubbed against the surface of the recording medium 1 strongly. Consequently, the toner image on the recording medium 1 is prevented from becoming erasable and being disordered because the image is adhered to the recording medium 1.

Abstract: PURPOSE:To obtain a pen input electronic equipment which is excellent in operability and durability and enables pen input operation without any feeling of incongruence by making a surface plate of elastic synthetic resin, and making both its surfaces nonglaring and carrying out processing for writing touch adjustments on the surface of the surface plate which is touched with a pen. CONSTITUTION:The surface plate 11 serving as a pen input surface is made of the elastic synthetic resin; and the surface 11a which is touched with the pen 8 and the surface 11b which is not touched are made nonglaring and the processing for writing touch adjustments is performed to give a rough feel to the surface 11a which is touched with the pen 8. This surface plate 11 is fitted on a housing window frame 13 having a step part 13 whose height is nearly equal to the plate thickness of the surface plate 11 of the housing of an electronic equipment. Thus, the surface 11a of the surface plate 11 which is touched with the pen 8 is made nonglaring to eliminate glaringness with external light and processed for writing touch adjustments to give the rough feel, so the pen 8 becomes hard to slip, thereby improving the writing touch.

Abstract: PURPOSE: To detect a connection condition without applying the current to a pellet by recognizing whether an initial bonding could be established or not accurately by detecting a tension of a bonding wire to be fed after completion of the initial bonding.  
     CONSTITUTION: A bonding wire 2 is drawn out from a wire spool 1 through a glass guide 4, and is introduced through pressing portion 5, guide 8 and 6 and clamp 9 to the top end of a bonding tool 10. Subsequently, the wire 2 is bonded by the tool 10 to a semiconductor pellet 13, thereafter, the tool 10 is transferred to the upper of a lead frame 15.
