Title: Pressure reference unit of weight type
Inventor: INOMATA HITOSHI
IPC: G01L27/00
Filed: 1978-08-30
Abstract: PURPOSE: To make easy the operation and maintenance and to increase the accuracy, by balancing the output pressure and the set weight balance.  
     CONSTITUTION: The differential transformer 4 is placed at the external circumference of the rotor meter 1, and it is connected to the servo valve 7 via the amplifier 6. Thus, when the output pressure P is fed to the rotor meter 1, the float 12 is lifted up, deviation voltage is produced in the differential transformer 4, and after amplification, it is inputted to the servo valve 7 and the air pressure from the supply air source 8 is reduced, the output pressure P is reduced, and when the float 12 is lifted down, the opposite operation is made. The float 12 is made stable at the set position to form the reference output pressure corresponding to the weight 3 automatically. The pressure can comparatively long time be kept to achieve desired purpose.

Title: Manufacture of square bottom bag from beltlike cylinder body and device therefor
Inventor: TAGUCHI TAKEO
IPC: B31B37/00
Filed: 1989-04-27
Abstract: PURPOSE:To drastically enhance manufacturing efficiency of a square bottom bag by feeding a synthetic resin film from a beltlike cylinder and extending it in a nearly triangular blade shape and sealing the interval of the respective holding parts as the lugs rectangular to the axial direction of the pinching rollers and forming the sealed parts of the side parts into the bladelike extending parts and cutting both the outsides of the sealed parts of the side parts and the end part becoming an opening edge. CONSTITUTION:The nearly central two edges of a pinched flat end edge are sucked and held by a vacuum sucking means 15 and opened a little. An extending means 17 is moved to the direction rectangular to the axial direction of a pinching roller 13. Two edges of a film 11 are mutually peeled and successively fed and extended to a nearly triangular blade shape which has the holding parts made of a pair of holding pawls 16 as a vertex. The film 11 between the holding parts is formed into a lug part 18 risen from the face of the other film. Then a sealing means 19 is moved to seal the whole lug part 18. Sealing of mutually parallel two parts is performed in the bladelike extending part of the film 11 around the pinching roller 13. Thereafter the outsides of the sealed parts 22 of the side parts are approached close and cut because these are unnecessary as a square bottom bag.

Title: Sewing machine driving device
Inventor: SHINOZAKI NOZOMI
IPC: D05B69/18
Filed: 1980-07-31
Abstract: PURPOSE:To reduce the power consumption, by controlling a current intermittently and suppressing its further rise, when a brake current rises swiftly and attains to a necessary ampere-turn. CONSTITUTION:When a current of a brake coil 4 rises and attains to a set point, an output of an operational amplifier 9 becomes L, and turns off a transistor (TR)Q2 and Q3 irrespective of an output of a microcomputer 8. When the TRQ3 becomes off, a current flow to the coil 4 from the electric power source is stopped, electromagnetic energy stored by itself is discharged through a diode D6 and a resistor R5, and a current is decreased. When the current flowing in this coil 4 is lowered to a set point, an output of the amplifier 9 becomes H again, clamp of the TRQ2 is released, the TRQ3 becomes on again, and the current of the coil 4 starts to rise again. As a result, the current flowing in the coil 4 becomes a saw tooth wave. In this way, when a brake current attains to a necessary ampere-turn, it is controlled intermittently and a further rise of the current is suppressed, therefore, a magnetic circuit having a high efficiency is constituted.
