Title: Manufacturing apparatus of heat-shrinkable tubing
Inventor: NISHIKAWA ICHIROU
IPC: B29K105/02
Filed: 1983-09-29
Abstract: PURPOSE:To obtain a heat-shrinkable tubing which requires no regulation of a supply air pressure and is not limited in the length of a material tube, by confining compressed air in the tube fed between delivery rollers 11 and draw-off rollers 14. CONSTITUTION:Delivery rollers 11 are kept open when a manufacturing process is started. Thereby a compressed air pressure is applied between the end of a material tube and take-up rollers 14. The material tube softened when passing through a heater 12 runs expanding through a cooling die 13, whereat an expanded part 10 of outside diameter is formed. When a detecting means detects the formation of this part, the feed rollers 11 stop their operation, and thereby compressed air is confined in a heating section. Therefore, the tube running continuously is expanded with a constant air pressure to form the expanded part 10, and thus no regulation of the air pressure is required even when the length of the material tube between the end and an expanding point 9 is lessened.

Title: Pneumatic actuator
Inventor: YAMAMOTO TOSHITAKA
IPC: F15B11/06
Filed: 1990-07-10
Abstract: PURPOSE:To enhance control accuracy by connecting a pneumatic tank through a throttle with the pressure control chamber of an actuator that performs supply/exhaust of pressurized air to the pressure control chamber based on a position command signal to actuate an operating part. CONSTITUTION:Pressurized air is supplied to the pressure control chamber 10A of the main body of a cylinder 10 based on a position command signal input to an electro-pneumatic proportional valve 20 and a feedback signal from a position detector 18, and a piston 14 is driven to a specified position. When a rise in pressure of the control chamber 10A is abrupt, air flows from the control chamber 10A to a pneumatic tank 32 through a throttle 30 and the rise in pressure of the control chamber 10A is suppressed, making the occurence of vibration on a piston difficult. It is the same in case of the pressure fall. When the rise/fall of pressure is slow, the pressure of the control chamber 10A and the pneumatic tank 32 is maintained in nearly equal pressure. Since pressure change can be damped, control of the position of the piston can be accurately performed even when the gain of a control system is made larger.
