IPC: F04C29/02
Filed: 1994-06-30
Abstract: PURPOSE:To prevent local abrasion of a vane caused by collision of lubricating oil backflowing from a lubricating oil reservoir part to the inside of a pump housing and the vane. CONSTITUTION:A communicating passage 40 to communicate rooms 24a, 24b partitioned by a vane 30, a pump housing 22 and a rotor 26 to each other are provided on the vane 30 supported by the rotor 26 free to move in and out in a vane type vacuum pump 20 to discharge lubricating oil 38 for pump lubrication and air simultaneously from an air discharge port 34 to a lubricating oil reservoir part 36 provided outside of the pump. Local abrasion of a contact part 30a with the rotor 26 of the vane 30 is prevented by mitigating an impact at the time of collision of the vane 30 and the lubricating oil 38 by way of releasing the lubricating oil 38 backflowed to the room 24a to the other room 24b through the communicating passage 40.

Abstract: PURPOSE:To automatically set up a delay time difference between respective signals to an allowable value or less by detecting a delay time difference between respective component signals constituting a video signal and controlling the delay time of each programmable delay line in accordance with the detecting level. CONSTITUTION:Each of synchronizing signal extracting circuits 2a to 2c extracts a synchronizing signal from a video signal constituted of three component signals, e.g. a luminance signal and two color difference signals, each of delay time difference detecting circuits 3a, 3b detects a delay time difference between respective signals from the extracted synchronizing signals and each of delay time difference detecting level coding circuits 4a, 4b codes each detected output level into a code of n bits. The delay values of respective programmable delay lines 5a to 5c for setting up the delay values of respective component signals are set up by the codes. Consequently, the delay time difference between respective signals can be automatically set up to an allowable value or less.

IPC: F27D15/00
Filed: 1998-04-06
Abstract: PROBLEM TO BE SOLVED: To produce a low heat generating type concrete admixture containing a large amt. of β-C2 S for a large-scale structure from a dephosphorized slag in a steel making process which is not effectively used. SOLUTION: Silica (SiO2 ) is added to an isolated lime content (CaO) of a dephosphorized slag in the steel making process so as to obtain C2 S compsn. Further, lime and silica are additionally compounded to obtain 2:1 molar ratio of CaO:SiO2 . The mixture is calcined at 950 deg. to 1200 deg.C for 1 to 3 hours to obtain slag containing >=55 wt.% β-C2 S. The belite slag thus synthesized is compounded in a normal portland cement (OPC) or the like, and if necessary, a gypsum is further added. Thus, the obtd. cement can be effectively used as a low heat cement.

Title: Digital pid controller
Inventor: MATSUO KEISUKE
IPC: G05B13/00
Filed: 1986-06-27
Abstract: PURPOSE:To eliminate variation of the manipulated variable by using a changing factor check filter to check primary and secondary differentiations with respect to the time and reducing the variation caused by the differentiation. CONSTITUTION:A digital PID controller contains a digital PID controller 11 connected with a process 10 for controlled system. The controller 11 includes a primary processing normal filter 12,a deviation arithmetic element 13, a proportional action arithmetic function part 14, an integral action arithmetic function part 15 and a differential action arithmetic function part 16. A changing factor check filter 17 is added to the part 16 to compare the differential change value of the process control value with the allowable value set previously and selects the prescribed output based on the result of this comparison. Thus the control value is used as it is as long as the differential change value is kept within an allowable range. While the control value is replaced with the value approximately equal to the preceding secondary derivative value and delivered if the control value is set outside the allowable range. In such a way, the value by the secondary differential operation is obtained and therefore the variation due to differentiation is reduced.

Title: Cvd apparatus
Inventor: YASUDA OKIMITSU
IPC: C23C16/458
Filed: 1982-08-31
Abstract: PURPOSE:To prevent any undesirable slide of a wafer and reduce the titled apparatus in size, by arranging such that the wafer is suction-held at the tip end of an arm disposed outside the CVD apparatus body and is horizontally loaded into and unloaded from the apparatus body, and moreover, is supported by a set of three vertically movable pins extending through both a heater and a plate. CONSTITUTION:With the lid of a container 2 opened, an arm 11 is driven to suction-hold the lowermost wafer 9 in a carrier 9 through a bore 11a formed at the distal end of the arm 11 and to transfer the wafer 9 to a position above a group of pins 6 inside a main body 1. The movement of the arm 11 is sensed, and the pins 6 are lifted up to support the wafer 9. The wafer 9 is released from the vacuum-holding, and the arm 11 is returned. The pins 6 are lowered to place the wafer 9 on a plate 5. A table 4 is rotated to repeat the above-described operation. After the plate 5 is fully loaded with the wafers 9, the lid of the container 2 is closed. Then, a shaft 3 is lifted up to a predetermined position and is rotated. The inside of the apparatus is raised in temperature by a heater 4, and a gas is supplied thereinto from a nozzle 7 to form an SiO2 film, for example, on the wafer surfaces. By this constitution, any air between the wafers and the plate 5 escapes through the through holes respectively receiving the pins 6; hence, the wafers are placed in position without sliding. Accordingly, it is made possible to prevent any foreign matter from flying up. Further, the main body can be reduced in size.
