Title: Formation of oriented film
Inventor: KANBE SADAO
IPC: G02F1/1337
Filed: 1989-02-27
Abstract: PURPOSE:To optimize the angle with a substrate in correspondence to the kind of a liquid crystal and the helix angle of the liquid crystal and to improve the contrast of a liquid crystal display body to an optimum state by applying a soln. prepd. by dissolving specific two kinds of diamines and tetracarboxylic anhydride on the substrate with transparent electrodes, then subjecting the coating to drying, calcining and rubbing treatments. CONSTITUTION:The soln. prepd. by dissolving the diamine compd. expressed by formula I, other diamine compd. and the tetracarboxylic anhydride is applied on the substrate and thereafter, the coating is subjected to the drying and calcining, then to the rubbing. In the formula I, R denotes hydrogen or alkyl group. Since the oriented film consists of a polyimide resin, the film has the excellent heat resistance which is the characteristic of the polyimide. The angle of the liquid crystal molecules with the substrate can be changed as desired from 0 to 5 deg. up to 22 deg. by changing the mixing ratio of the diamine compd. of the two components and the need for preparing orienting agents to meet with the kind, helix angle, etc., of the liquid crystal is eliminated. Dealing with all cases is possible in this way by preparing two kinds of the diamines and the tetracarboxylic anhydride.

Title: Health care device
Inventor: KUNITAKE YASUHIRO
IPC: G01N33/493
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To prevent a surface from gradually oxidizing with the lapse of current carrying time and prevent sensitivity degradation of a measuring means, by controlling a potential changeover means with a control means to set excreta measuring means to a high potential, when a prescribed condition is satisfied. SOLUTION: A urine sugar sensor 28 of a measuring unit 11 specifically identifies glucose from multiple components of urine sampled with a urine sampling arm 32 of a urine sampling unit 12, and converts it to an electric signal. Platinum is used as an action electrode material of the urine sugar sensor 28, and the action electrode is impressed with a constant voltage for a reference electrode. When the voltage impression is continued, the surface is gradually oxidized with the lapse of current carrying time to reduce sensitivity of the platinum for hydrogen peroxide. Therefore, when existence of a user in a toilet is detected by a human body detecting sensor 260, a controller 36 controls a potential changeover means to set the urine sugar sensor 28 to a high potential.  Thus, the sensitivity degradation of the platinum for the hydrogen peroxide and the sensitivity degradation of the urine sugar sensor 28 for glucose are prevented.

Abstract: PURPOSE:To enable continuation of a comfortable feeling by providing an electric motor having a multistage notch to rotate a blade, a signal generating means to generate a signal based on a discrete dynamic system sequence, a deciding means to classify signals by a region divided by a threshold, and a rotation control means. CONSTITUTION:When a power source inputted to an electric fan 1, signals are orderly generated from a signal generating means 2, and the signal has a value following a discrete dynamic system sequence. The discrete dynamic system sequence follows a specified calculation formula, but is a sequence to produce a non-linear result. In which case, when orderly calculation is effected on a discrete dynamic system sequence xn+1=4xn(1-xn) serving as initial valves x0=0.7 and yn=xn+1, yn to xn outputs a value shown in a figure. The output signal is discriminated by using a threshold by a deciding means 3 to classify results by a layer. A rotation control means 4 receives the deciding result of the deciding means 3 and generates a notch switching pattern, and the pattern forms that having no repeat period.

Abstract: PURPOSE:To permit later sealing operation to be effected accurately and easily by a method wherein, in the process of drawing out sealing material, the seal piece formed by giving the sealing material a folding line or stamping it out is made to curve in the direction opposite to its curling direction. CONSTITUTION:Sealing material 21 is passed around a guide pulley, folded in a longitudinal direction, inserted into an elongated hole formed by both the slits 32a and 33a of a folding device 31, unfolded into the original form and the sheet material thus spread out is supplied to a delivery device. When the sealing material 21 is set in a predetermined position on a lower die 38b of a die set 38, a suctorial transfer part 47 is moved upwards by the action of a cylinder 45 and, at the same time, an upper die 38a thereof is moved downwards, whereby a seal piece 51 is stamped out by the die set 38 into a predetermined shape. In this case, since the outer peripheral part of the sucking face is made slightly higher than its central part, the seal piece 51 is curved in the direction opposite to the regular curling direction by the sucking action of vacuum holes 47a, and 47b.

IPC: H01L21/30
Filed: 1989-02-27
Abstract: PURPOSE:To enable element electron images in various shapes and size to be made by accelerating electron speed by a method wherein previously and optically patterned light is projected on a photoelectric surface so as to form an electron source in surface corresponding to the pattern and accelerating the generated electrons for the formation of the electron images in surface on a projection surface. CONSTITUTION:When an optical pattern is projected on a photoelectric surface 12 using an optical pattern projecting means 10, photoelectrons are radiated in surface from the positions on the photoelectric surface 12 corresponding to the pattern. These photoelectrons accelerated by an accelerating means 14 advance to a projection surface 15. Electron images are formed by projection on the projection surface 15 using a projecting means 14, i.e., an electron lens 16 comprising a magnetic or electric field. In such a process, an electron deflecting means can be actuated so that the overlapped parts may be controlled to make electron images in various shapes and sizes.

Title: Composite semiconductor device
Inventor: IWASAKI MASAMI
IPC: H01L27/06
Filed: 1984-03-12
Abstract: PURPOSE:To contrive the decrease in forward voltage of a diode and the reduction in reverse recovery time by a method wherein the surface of a semiconductor substrate in the region of diode formation is made lower in level. CONSTITUTION:An impurity of the same conductivity type as that of an N<-> type semiconductor substrate 10 is diffused from the side of one main surface. Next, the side of the other main surface of this substrate 10 at the region scheduled for diode formation is removed to a required depth by etching or the like, resulting in the formation of the lower part 21. Successively, the base region 141 of a Darlington transistor Tr and the anode region 142 of the diode are formed respectively as the first P type region and the second P type region by selective diffusion of a P type impurity from the side of the other main surface. A collector electrode 16 serving as the cathode electrode of the diode D is formed on the one main surface (back) of the substrate 10. Thereby, the thickness of a high-resistant layer 11 immediately under the anode region 142 of the diode D becomes smaller than that of the high-resistant layer 11 immediately under the base region 141 of the Darlington transistor Tr; accordingly, the forward voltage drop VFM of the diode D decreases.
