Title: Etching of gaas substrate
Inventor: SHIMA AKIHIRO
IPC: H01L21/306
Filed: 1986-07-22
Abstract: PURPOSE:To perform etching in order to provide both normal and inverted mesa grooves in the same direction in a GaAs substrate and to form a hexagonal groove, by using aqueous solution, whose main components are organic acid and hydrogen peroxide water, changing the mixing ratio of the organic acid and the hydrogen perox ide water, and controlling the shapes of the grooves. CONSTITUTION:When etching is performed with the aqueous solution of 1 tartaric acid and the aqueous solution of 1 hydrogen peroxide, etching speed has the quickest value. A normal mesa groove 2c having the groove shape of a letter V is obtained. Its side surface becomes a {111} GA surface 7 in the normal mesa shape. When the etching is performed with the aqueous solution of 1 tartaric acid and the aqueous solution of 12 hydrogen peroxide, the etching speed is slow. The shape of the groove becomes an inverted mesa groove 2e. The side surface of the groove becomes a{111} As surface 9 having the inverted mesa shape. When the aqueous solution of 1 tartaric acid and the aqueous solution of 5 hydrogen peroxide, i.e., an intermediate compositions, are used, the etching speed is the intermediate speed between the groove 2c and the groove 2e. The shapes become both the {111} Ga surface 7 having the normal mesa shape and the {111} As surface 9 having the inverted mesa shape. A hexagonal groove 2d, in which both surfaces appear on the side surfaces of the groove, is formed.

When the sliding door is opened while the fitting section of the sliding door handhold 1 is left in a sliding door fitting opening, the sliding door fitting opening is not narrowed so much because the sliding door handhold 1 has a fine-width shape. Since the finger hook space is large, opening/ closing actions can be easily made.

Abstract: PURPOSE:To enhance the heat efficiency of a resistor dot and to obtain a thermal head imparting good printing quality, by forming a rectangular clearance pattern having no electrode film on each electrode film to allow the same to position on the area of the electrode film separated by predetermined quantity from the boundary part with a resistor dot and forming each electrode film so that the expanse thereof is not broken. CONSTITUTION:A heat-insulating layer 2 composed of an insulating material and a resistor film 3 are successively laminated onto a substrate 1 and a pair of electrode films 4a, 4b are arranged on the resistor film 3 so as to leave a predetermined interval. The electrode films 4a, 4b are formed into a rectangular shape having a predetermined expanse, and rectangular clearance patterns 6, 7 are formed at positions slightly separated from the boundary parts with the resistor dot 3a so as not to breaks the expanses of the aforementioned electrode films 4a, 4b. Even if the heat generated in the resistor dot 3a passes through the electrode films 4a, 4b along the sub-scanning direction A and is apt to escape to both end sides of a thermal head, because the passages 10, 11 of escape ports are narrow, only slight heat escapes. Therefore, charged power is effectively used for the generation of heat.

Title: Pwm inverter
Inventor: NAGASAKA NAGAHIKO
IPC: H02M7/48
Filed: 1980-12-15
Abstract: PURPOSE:To simplify the construction of a PWM inverter by employing only a set of a high speed breaker and a DC reactor in all inverter device. CONSTITUTION:Basic devices (controlled power source) S1, S6 are connected in series for each two devices, three series circuits thus connected are connected in parallel with each other, a breaker Sw operated by the shortcircuit current and a DC reactor L are connected in series between the terminals X and Y, and with the common connecting points U, V, W of the respective sets of the controllable power sources as output terminals three sets of AC motors M are connected thereto. When the devices S1 and S4, S3 and S6, or S5 and S2 are simultaneously conducted ON due to an erroneous operation, a shortcircuit current flows through the series circuit (protecting circuit) of the reactor L and the breaker Sw. In this case, the DC reactor L serves to delay or suppress the rise of the shortcircuit current, allowing a current detector CT to detect the shortcircuit current in the meantime to detect the defect in advance, thereby controlling the devices S1 to S6 to suppress the current. When it is impossible, the breaker Sw is operated by an electromagnetic device MC to break the series circuit so as to protect it.

Abstract: PROBLEM TO BE SOLVED: To stably and highly accurately hold a large-sized heavyweight optical member with less surface distortion by arranging plural pressing mechanisms having a pressing force in the radial direction on the inner peripheral surface of a holding member and pressing and holding the optical member. SOLUTION: The optical member holder 9 is constituted by arranging plural pressing mechanisms (elastic member) 11 provided with a nearly constant pressing force in the radial direction and made of rubber member, etc., on the inner peripheral surface of the metallic outer frame 10 functioning as a holding member at equal intervals. The optical member (concave mirror) 5 is held inside the metallic outer frame 10 whose inside diameter is slightly made larger than the outside diameter of the optical member 5 through the pressing mechanisms 11 constituted so as to have a pressing force in the radial direction. In this device, among the pressing mechanisms 11 installed in the metallic outer frame 10, each pressing mechanism installed in the upper half part is not provided with the pressing force because of the installation of a stopper.  Besides, the sum of the pressing forces of the pressing mechanisms 11 provided with the pressing force and installed in the lower half part of the frame are smaller than the dead weight of the optical member 5, and the downmost part of the optical member 5 comes into tight contact with the metallic rigid outer frame 10, thus, the position of the optical member 5 is stabilized.
