摘要： PROBLEM TO BE SOLVED: To discharge high-voltage residual electric charge connected to facing electrodes easily at a stroke by arranging the electrodes opposite to each other at a specified distance at both ends of a natural air column in a cylinder, and passing laser beams through the axis of the air column to ionize the atmosphere along a laser beam passage. SOLUTION: High-voltage side and ground side electrodes 3, 4 are arranged opposite at a distance which is normally incapable of spontaneous discharge at both ends of an air column in a cylinder 2, and after cutting off a high- voltage generator, the electrostatic capacity 1 of a cable and the high-voltage generator is connected to both the electrodes 3, 4. Laser beams are passed through an axis of the air column from a laser generator 5. The atmosphere of a laser beam passage is therefore ionized, and withstand voltage is lowered in a marked degree for discharging the electric charges of the electrostatic capacity at a stroke. The ionization of the atmosphere is further accelerated by this discharge to completely discharge almost in a state of short circuit. As a result, a high-voltage discharge switch is obtained that can discharge the high voltage electrostatic capacity with a simple, low-cost equipment to prevent spread of danger.

摘要： PURPOSE:To lessen the forced swirl in an engine having a fuel valve in the circumference of a cylinder cover so as to reduce the burnout of the piston crown, by providing two jet holes having a jet angle of a cone angle. CONSTITUTION:The spherical jet port N' is provided with an oblique angle to a cylinder axis. The jet angle theta of the jet holes n' that is obtained by connecting points (a1, a2) on the outer circumferential surface of the sphere with the center of the sphere is defined as the cone angle. The cone angle is 1/2 of the angle between the jet hole center line and an plane perpendicular to the cylinder axis. The jet direction of the jet hole n' in the undersurface is directed toward the center of the piston crown. The jet stream is jetted evenly into the combustion chamber, so that the burnout of the cylinder cover, the exhaust valve, the piston crown, etc. can be reduced.

摘要： PURPOSE:To handle signals with a very high sensibility not affected by disturbing light by applying a strong light enough to overcome the disturbing light to a light receiving system beforehand or an electric control voltage with an equal effect thereto. CONSTITUTION:A light emitting body is excited intermittently. A light emitted is received and then amplified synchronizing this intermittent actions to reduce the effect of a disturbing light. Prior to it, a large quantity of light or an equivalent electric signal is applied to a light receiving element 3. With such an arrangement, the relation between the intensity of input light and the output voltage appears at such a high sensibility as shown by a point B thereby removing effect by disturbing light.

摘要： PURPOSE:To change arbitrarily the equivalent output resistance of the main amplifier, by inserting an auxiliary resistance between the main amplifier and the load resistance and amplifying differentially its terminal voltage by the auxiliary amplifier and by synthesizing the output and the main input of the main amplifier and by changing this synthesis ratio. CONSTITUTION:Auxiliary resistance 2 is inserted between main amplifier 1 and load resistance 3. Voltage generated at both terminals of auxiliary resistance 2 are amplified differentially by auxiliary amplifier 4, and this output and the main input of main amplifier 1 are synthesized. This synthesis ratio is changed by the ratio of resistances 5 and 6 to change the effective output damping resistance while supplying all of the effective maximum output of the amplifier to the load as it is.

摘要： PROBLEM TO BE SOLVED: To obtain a fabric optimal as a bathrobe fabric having a skin touch, a crispy touch, a brisk body (stiffness), and the like which are necessary for the bathrobe. SOLUTION: This bathrobe fabric is obtained by using a small number of such thick twisted silk yarns or spun silk yarns as not thought for a silk fabric as warps and further using two to four kinds of cotton yarns having a fineness difference maximally reaching 1:2 as wefts. When the cotton yarns as the wefts are partially or wholly replaced by ramie-cotton yarns, a more excellent bathrobe fabric can be obtained.

摘要： PROBLEM TO BE SOLVED: To easily find a pull switch even in a dark place by fixing a pilot lamp to the tip of a string of a pull switch, winding a power source cord around the string of the pull switch or attaching the cord to the string, connecting the cord to the pilot lamp, and connecting the power source cord to an upper power source. SOLUTION: As a pilot lamp 3, for example, liquid crystal is used, and the pilot lamp 3 is fixed to the tip of the string 1 of a pull switch. A power source cord 2 is wound around the string 1 of the pull switch or attached to it and connected to the pilot lamp 3. The power source cord 2 is connected to an upper power source and fixed to the string 1 of the pull switch. Even in a dark room at midnight, by lighting the pilot lamp 3, the position of the string 1 of the pull switch is easily confirmed. Only the power source cord 2 can also be used without use of the string of the pull switch.

摘要： PURPOSE:To properly check a battery in a short time by charging and discharging a battery to be checked with a constant current, detecting fluctuation in voltage at the terminal of the battery, and measuring the magnitude of fluctuation in the terminal voltage. CONSTITUTION:A battery 2 to be checked is charged using a constant current source 1. A current is intermittently passed through a load resistance 5 by means of an oscillator 3 and a driver 4. While no current flows through the resistance 5, the battery 2 is not charged, whereas when the resistance 5 is connected the remaining part of the current flowing through the battery 2 is made to flow through the battery 2. As charging and discharging operations are repeated by thus turning the resistance 5 on and off, the voltage at the terminal of the battery 2 rises at the time of charging and lowers at the time of discharging. This fluctuation in voltage at the terminal of the battery 2 is amplified by a battery voltage fluctuation amplifier 6, rectified by a rectifier 7 and read using a dc voltmeter 8.
