Abstract: PURPOSE: To enable accurate lead-out even under any conditions, by the designated operation in response to the detected state of the magnetic tape signal state detection circuit.  
     CONSTITUTION: In leading out the n-th music recording from non-signal section, the display of the display unit 22 is changed to n when the lead-out switch 7 is ON by n-times after the application of power supply, and the counter 15 performs memory at the same time. Next, when the fast feed switch 4 is ON, the Schmitt trigger circuit 12 in connection with the head 2 detects the trailing of the recording and the counter 15 for lead-out counts it. In this case, the trailing signal of the monostable multivibrator 17 is inputted to the counter 15. Further, the number of recording trailings and the n sets of recordings stored are compared, the lead-out detection signal is produced when in agreement, and automatic transfer to the play- mode can be made. Then, if the lead-out for m-th recording is made during reproduction, when the lead-out swich 7 is ON by m times, FF28 is set and m is displayed through the lead-out display changed. After that, when the switch 4 is ON, high speed run is made with the plunger solenoid 9 and FF28 is at play-mode.

Title: Single crystal pulling apparatus and controlling method therefor
Inventor: MAEDA SUSUMU
IPC: C30B15/22
Filed: 1992-01-29
Abstract: PURPOSE:To obtain a crystal having decreased thermal strain of crystal near the solid-liquid interface, low crystal defect content and microscopically uniform oxygen concentration by rotating a crystal pull-up shaft relative to a crucible supporting rod. CONSTITUTION:A crucible 53 made of graphite or quartz, etc., is placed in an air-tight vessel 51. A cylindrical graphite heater 59 for melting a polycrystalline semiconductor raw material 57, etc., at a high temperature is placed at the outside of the crucible. The semiconductor raw material 57 melted by the heat of the heater is made to contact with a seed crystal 63 attached to a crystal pull-up shaft 61 and the seed crystal 63 is pulled up while rotating the seed crystal 63 and/or the crucible 53 to effect the growing of a single crystal 64. When the rotational speed of the crucible 53 is set to >=100rpm, the solid-liquid interface is flattened and, as a result, the thermal strain of the crystal near the solid-liquid interface is decreased to obtain a crystal having low defect content. A definite amount of oxygen is constantly supplied by the stirring effect of the melt at a high rotational speed of the crucible to form a crystal having microscopically uniform oxygen concentration in the direction of the crystal length.

Filed: 1982-03-15
Abstract: PURPOSE:To obtain economically the titled compound useful as a raw material for preparing polyoxymethylene by divisional synthesis (by dividing the reaction into a low temp. reaction and a high temp. reaction), by using formed steam from a high-temperature reactor as heat source for a low-temperature reactor and a condensation column, reacting formaldehyde in the presence of a heteropoly-acid under heating. CONSTITUTION:Formaldehyde is reacted in the presence of a heteropoly-acid (e.g., phosphor tungstic acid, silico-tungstic acid, etc.) under heating. The reaction is carried out using formed steam from a high-temperature reactor (at <=150 deg.C, preferably at <=130 deg.C) as heat source for a low-temperature reactor (at <=95 deg.C, preferably <=60 deg.C) and a condensation column, and trioxan is prepared by a divisional synthesis. In the reaction, if a given relationship between the amount of a catalyst and a necessary temperature (boiling point) is kept by the use of the heteropoly-acid, a stable reaction system can be maintained. Since a low- temperature reaction which is advantageous in equilibrium is used, energy reducing process is made possible. The formed heat from the reactor of high-temperature reaction can be used efficiently by the divisional process of the reactors.

Title: Time monitoring method for line controller

Filed: 1988-02-24
Abstract: PURPOSE:To prevent the tentative reduction of processing capability due to long time occupancy of an MPU in the timer processing by setting a timer applying time monitor corresponding to a line and operating the timer in a timing different from the line. CONSTITUTION:The timer processings for aN timers in total are not applied simultaneously, they are divided into (a) timer groups (>=1) at every line and the timer processing of each timer group is executed in the timing different from each line by a period in common to all the lines. That is, since the timer processing of different lines does not have simultaneous expired timers because of different execution time and the simultaneous expiration of timers are limited to the (a) timers of the same line. Thus, the maximum consecutive timer in the timer processing is independent of the line number N and the reduction in the processing capability due to long time occupancy of the MPU in the timer processing is avoided.
