Title: Differential pressure detector
Inventor: TAMAI MITSURU
IPC: G01L7/08
Filed: 1989-02-13
Abstract: PURPOSE:To suppress a zero-point fluctuation by arranging a center diaphragm and side diaphragms which is formed in a disc with a diameter thereof the same as the center diaphragm having a circular hole at the center thereof and laminated respectively on both sides of the center diaphragm. CONSTITUTION:A protective diaphragm 60 is made up of one center diaphragm 61 and side diaphragms 62 disposed adjacent to each other respectively on both sides of the center diaphragm. The diaphragms 61 and 62 are all formed in a flat disc with a diameter thereof being the same but the diaphragm 61 has no center hole while the side diaphragms 62 have a hole 62a at the center thereof. The existence of the hole 62a eliminates possible friction based on a radial shift in a deformation at the center between adjacent side diaphragms 62 to reduce a surface friction force therebetween. As a result, the protective diaphragm 60 returns to an initial position almost completely when a biased pressure working thereon is removed, thereby enabling the suppression of a zero-point fluctuation eventually.

Title: Timer for controlling plural channels
Inventor: TANAKA KAZUO
IPC: H04Q11/04
Filed: 1988-02-16
Abstract: PURPOSE:To accurately perform a processing with a few number of RAMs by employing a system to process plural channels by software in parallel and independently by using a CPU and plural RAMs in a timer for controlling the channel of a PC<M local station. CONSTITUTION:A control part 1 receiving a signaling signal from the channels (ch1-chn) sets the signaling states of (n) channels on a first RAM2. A second RAM3 divides and sets the value of the RAM2 at every channel, and also, shifts the value according to the state change of the RAM2. When the RAM3 goes to a prescribed bit value, the value is set on the RAM4 corresponding to the channel. Simultaneously, the count operation of first-n-th counter RAMs (5-5n) corresponding to each channel, that is, a timer operation is started. When the value goes to a prescribed count value, the control part 1 generates timer output corresponding to each channel.

Title: Batch adjuster
Inventor: NISHIHARA TADASHI
IPC: G05B11/44
Filed: 1980-03-18
Abstract: PURPOSE:To prevent reset wind-up with small size simply, by switching the flow path with the 1st nozzle back-pressure signal provided at the flow path to the integrating bellows of an air pressure amplifier and releasing the flow path to air with the 2nd nozzle back-pressure signal. CONSTITUTION:When the output Pout is smaller than the operation set pressure Pset, the link 31 receives a force of right direction in figure. Thus, a gap is produced for a nozzle 41 and a link 34, the nozzle back-pressure is zero and a switch 61 is opened. On the other hand, since a link 53 closes a nozzle 42, the nozzle back pressure P42 is the supply pressure and a switch 62 is closed. Then, when the output Pout reaches the operation set pressure Pset, the link 31 is subjected to the pressure toward left in figure, the switch 61 is closed and the switch 62 is opened. Thus, when the pressure Pset in set higher than the variance of the output Pout, if the output Pout is increased from the adjusting operating range, the pressure of the integrating bellows 54 of an air pressure amplifier 57 is released in air.
