Title: Friction drive gear for rotary body
Inventor: IDA KATSU
IPC: F16H13/02
Filed: 1982-07-22
Abstract: PURPOSE:To extrememly reduce irregularity in speed, by providing a fine adjusting mechanism capable of changing the position of a friction wheel relative to a rotary body. CONSTITUTION:An adjusting plate 44 for a motor-supporting member 6 comprises arms 62, 64, 65 slidably supported respectively in slots 53a, 54, 55 formed in a fixed member 43, is energized leftward by a compression coil spring 66, and can be finly adjusted substantially horizontally in transverse directions (y) by an adjusting screw 56. On the other hand, a motor 5 is rotatably supported on the plate 44 together with a motor-fitting member 33 by a pin 61. Accordingly, when the plate 44 is moved by a minute amount by the adjusting screw 56, the pin 61 is moved horizontally leftward by the fine adjustment quantity. Since the motor 5 is supported by fixing pins 35, 61 and the pin 35 provided at a rear part is not moved, when a supporting point S of the pin 61 provided at a front part is moved, the motor 5 is rotated rightward with a supporting point R of the pin 35 as a center, a center shaft of the motor is also rotated in accordance with the fine adjustment quantity, so that, for example, the axis of the motor is deviated from the center Q of a capstan pulley 9 by an amount (x), and a motor pulley 8 is set at this position.

The pump 6 is operated at some time and stopped after a period T1, and the pressure is detected after a period T2. When a high-viscosity raw liquid is vacant or near vacant, the state of the pressure P1 lowered during the period T1 is not recovered, and the detected pressure P2 is kept at the preset value PS or below as shown by a broken line. When a large quantity of liquid is left, the pressure is dropped to the pressure P1 during the period T1 then recovered, and it exceeds the preset value PS after the period T2. Vacancy can be detected by comparing the pressure after the period T2 with the preset value PS.

Abstract: PURPOSE:To make a return to a main program unconditionally at a program's request without reference to the number of times of the calling of a subroutine by providing a circuit which changes a stack pointer by a program or alters the contents of a stack memory circuit. CONSTITUTION:A control circuit 4 outputs a reset signal R (low active R=0, but normally R=1) when decoding the resetting operation of the stack pointer by an instruction in the program.

Title: Production of styrene/maleic acid copolymer sulfonate
Inventor: YAMAMOTO FUMITADA
IPC: C08F222/02
Filed: 1984-06-25
Abstract: PURPOSE:To facilitate the production of the titled copolymer sulfonate by effectively removing super-fine CaCO3, by using a solid-ejecting centrifuge in sulfonating a styrene/maleic acid copolymer. CONSTITUTION:In sulfonating a styrene/maleic acid copolymer by adding concentrated sulfuric acid or the like thereto, CaCO3 powder as a by-product is removed by means of a solid-ejecting centrifuge. Thus the CaCO3 in the form of super-fine particles can be effectively removed. By previously separating and removing concentrated sulfuric acid or the like, which remains by infiltration in the styrene/maleic acid copolymer sulfonate in its production process, the amount of the CaCO3 precipitate as a by-product can be decreased. In addition, it is also possible thereby to reduce the amount of Ca(OH)2 necessary for neutralization.
