Title: Preparation of sample for observing cross section of sheet or film
Inventor: NAKAGAWA NOBUMASA
IPC: G01N1/36
Filed: 1980-06-30
Abstract: PURPOSE:To make a sample in the precise cross sectional condition easily in the  short time by hardening the sample with an adhesive agent of the room temperature  setting type and by cutting its end surface with a super microtome. CONSTITUTION:Reinforcing sheets 3 are laminated on both surfaces of a sheet or film 1 by a rapidly drying adhesive agent 2 of the room temperature setting type. When a thick sheet is employed, the outer layer of the sheet 1 is strengthened only with said adhesive agent 2. After the adhesive agent 2 that reinforced the sheet 1 is hardened, the end surface for observation of the sheet 1 is cut roughly several times with a super-microtome and the surface cut further one or two times is taken as the  observation surface. With such a method, it is possible to expose the true cross  section of the sheet 1 without requiring skillfulness.

IPC: H01L27/15
Filed: 1984-05-09
Abstract: PURPOSE:To form the contour of light-emitting ranges and the arrangement of centers on the light emission of each light-emitting element in straight lines by moving and shaping opening sections in diffusion stopping regions corresponding ti a plurality of the light-emitting elements in the direction that the opening sections deny light-emitting region sections in the lower sections of the diffusion stopping regions through lateral diffusion. CONSTITUTION:A plurality of opening sections 1 are shaped on a GaAsPonGaAs substrate, and Zn is diffused selectively to form light-emitting regions 2. Metallic electrodes 3 are shaped, and used as bias voltage supply sections. The light-emitting regions 2 are formed as the results of lateral diffusions toward the lower sections of diffusion stopping layers from the opening sections 1, and the ratios of the distances of lateral diffusions to diffusion depth are determined by the presence of buffer films to impurity diffusion and the conditions of the buffer films. The distances of lateral diffusions are computed in order to solve trouble in which the centers of the light-emitting regions 2 and the opening sections 1 are biassed to one side, and the positions of the opening sections are moved previously in the direction that trouble due to lateral diffusions is eliminated so that the luminescent centers of a plurality of the light-emitting elements are arranged on a straight line.

Title: Excitation control unit of brushless synchronous motor
Inventor: CHIBA TOSHIHARU
IPC: H02P9/14
Filed: 1978-07-27
Abstract: PURPOSE: To protect the burning of a field coil when the number of revolution of a motor drops by means of constant voltage control through zener diodes around the rated number of revolution of the motor and automatic voltage regulation by a function generator for less than the rated number.  
     CONSTITUTION: The standard voltage, when the number of revolution is over N 1 , is controlled through a zener diode. Then the output voltage of a function generator is cut by a diode D 1  because it is higher than the voltage of the ZD. When the number of revolution comes under N 1 , the output voltage of the function generator PG is automatically switched on from the standard voltage VZD to V because it is lower than the voltage VZD of the zener diode ZD. Therefore the generator voltage Vo and the field current If are controlled. In this method the increase of the field current when the number of revolution falls and the deterioration of the constant voltage control accuracy due to the effect of the function generator can be protected.

Abstract: PURPOSE:To enable a cooling capacity acting as a freezing cycle to be always realized properly by a method wherein a when a coolant of a low boiling point in a non-azeotropic mixed coolant is separated from a high boiling coolant, a separating function specific to a column is effectively utilized. CONSTITUTION:A flowing non-azeotropic mixed for a column 2 is separated into a low boiling point coolant and a high boiling point coolant in response to a function specific to the column 2. A low boiling point coolant flowing out of the column 2 prior to the high boiling point coolant passes through an electrical switching means 5, flows to an accumulation means 4 and is then cooled and stored there. After this operation, as a separation required time determined according to an actual temperature of the column 2 elapses, a second electrical controlling means 8 change over an electrical switching means 5 to a second switching state, so that the high boiling coolant remaining in the column 2 passes through the electrical switching means 5 and flows into the compressor 1a. Repeating the above-mentioned action causes all the low boiling point coolant to be stored within the storing means 4 and at the same time the coolant circulating in a compressor 1a, a condenser 1b, a switching means 1c and an evaporator 1d becomes only a coolant of high boiling point.
