Title: Real time timer setting device
Inventor: TANAKA KIYOTO
IPC: G04G7/00
Filed: 1989-05-25
Abstract: PURPOSE:To accurately set up a real time timer value even in travelling by comparing real time timer values stored in the 1st and 2nd real time timer registers with each other and setting up respective values so that these values are equal to each other. CONSTITUTION:Real time timer values stored in both the real time timer registers 11, 5 included in a control device 7 are compared with each other by a comparator 17. A difference between both the values is supplied to a timer updating interval changing circuit 15, and when the real time timer value of the register 11 is larger than that of the register 5, the updating interval of timer updating interval signals supplied to these registers through the circuit 15 is increased. Thereby, time reverse or time jump which may be generated in a conventional device can be suppressed even in travelling and a real time timer value can be accurately set up.

IPC: G11B15/467
Filed: 1987-05-27
Abstract: PURPOSE:To attain stable tracking control even if the linearity of a track is shifted from that of a head by executing tracking control corresponding to the respective linearity states. CONSTITUTION:Since error signals obtained from both tracking areas (ATF) 1, 2 formed on the tracking start and end terminal parts of a track are respectively set up on the basis of respective terminal parts, the references of the error signals obtained from the ATF1, 2 coincide with each other when the linearity state of the track coincides with that of the head, so that tracking control is executed by utilizing all error signals. When both the linearity states are shifted, the references of the error signals obtained from the ATF1, 2 are different, so that either one of them is selected and the tracking control is executed on the basis of the selected error signal. Even if respective linearity states are different, stable tracking control can be executed.

Title: Dry turbo vacuum pump
Inventor: SAKAGAMI SEIJI
IPC: F04D19/04
Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To stabilize a gas flow in a pump and improve exhaust efficiency of the pump, by forming a partition forward in the direction of rotation of a suction hole of a circular flow pump top step, when the gas sucked from a pump suction hole is compressed and exhausted through an exhaust hole to or near the atmospheric pressure condition. SOLUTION: In starting of a pump or in a transient condition that a large amount of gas flows from a pump intake hole 4A, a centrifugal pump step 3 acts as a centrifugal compressor because the pressure of the pump intake hole 4A becomes higher. A flow path between a centrifugal blade 3A and a blade placed on a centrifugal stator 3B acts as a return channel. The entered gas is compressed at the centrifugal pump step 3, and flows to a space between the centrifugal stator 3B and a centrifugal pump step 3 circumferentially and uniformly. By forming a partition 14 in the direction of rotation of a suction hole of the circular flow pump to step in a space 13 between the centrifugal pump step 3 and the circular flow step 2, the gas can flow uniformly in the direction of rotation of a pump rotor 1 in the space 13.

Abstract: PURPOSE:To obtain a container with an excellent openability and at the same time, which can completely pour out a content by a method wherein the title lid is equipped with a laminated base body and a first base with a band to cut off a partially openable part, and the material of the lid is made of a different material from the laminated base body material. CONSTITUTION:A lid 1 is a laminated body with a first base 10 and a second base 40. The first base 10 is a base body which has a first layer 11 and a second layer 15 on both sides of an intermediate layer 13 containing polybutylene terephthalate or polycarbonate. The lid 1 has the laminated base body 10 for which these layers are coextruded and a base 55 which is buried roughly along a partially openable part contour in order to cut off a partially openable part P. The material of this band 55 is made of a material with different mechanical properties from the laminated base body material of the first base, e.g., an amorphous copolymerized polyethylene terephthalate. Thus, since the material of the band 55 is made of a material with different mechanical properties from the laminated base body material of the first base, the openability is excellent, and at the same time, the outermost part of the partially openable port can be made to be the inner peripheral edge of the container mouth, and therefore, a content can be assuredly poured out.

Then, the thermally oxided film 12 is selectively etched using the resist film 13 as a mask. Subsequently, after the resist 13 is removed, a groove 14 is formed by performing a selective etching on the Si substrate 11 using the thermally oxided film 12 as a mask. When the thermally oxided film 12 is etched, the upper surface of the Si substrate 11 is exposed a little, and the corners of the upper end of the Si substrate 11 are rounded off when its sputter etching is performed. Then, the thermally oxided film 12 is exfoliated completely. After the substrate 11 is etched, a before-oxidation treatment is performed, a gate oxide film 15 is formed on the substrate, and a polycrystalline Si film 16 is formed thereon.
