Patent JP-H09204710-A (JP)
Title: Motor device
Inventor: HIRANO KENICHI
IPC: G11B21/10
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To provide the device, which copes with the variation in the starting time of a motor, by detecting the rotational condition of the motor. SOLUTION: The encoder of the motor governor, which is a detecting means, detects the counter electromotive force caused in proportion to the rotational speed of the motor. Then, a CPU discriminates whether the motor is normally rotated or not based on the magnitude or the frequency of the electromotive force detected by the encoder (S100). After this process, a discrimination is made to determine whether a prescribed time has elapsed or not (S102). This process is repeated till a prescribed time elapses. After the prescribed time, the plunger in the section to be driven is started (S104). Thus, the variation in the motor starting time is coped with and when the motor starting requires much time, a time required to start the mechanism is secured without fail and the occurrence of malfunction is prevented.  When the motor starting requires less time, unnecessary motor rotation is eliminated and a time required for the completion of the operation of the mechanism is reduced.

Title: Air bearing enforceable in vacuum area
Inventor: SOGARD MICHAEL R
IPC: H01L21/683
Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To unnecessitate a bearing surface finished by a wide precision machine and to reduce a manufacturing cost by providing an output path of gas supplied through an orifice between a flexible structure and the orifice. SOLUTION: Pressurized air is supplied to an air bearing structure 54 through a path 58. Air is delivered from an orifice 60, radially distributed on a substrate 50 and discharge grooves 62, 68 are provided concentrically with the orifice 60 to prevent the air from reaching a vacuum area. An inside discharge groove 62 leads to an air discharge manifold part 64, an outside discharge groove 68 leads to an air discharge manifold part 70, and differential vacuum pressure is impressed on the manifold parts 64, 70 and is discharged. Wall structures 78a, 78b concentric with the outside discharge groove 68 are constituted by fixing a seal plate to an end of a flexible cantilever and gas is prevented from escaping in surrounding vacuum. As a result, a bearing holds vacuum and is capable of properly operating for quick and precise movement.

Title: Radar pulse signal analysis device
Inventor: KAWAI JUN
IPC: G01S13/78
Filed: 1989-01-23
Abstract: PURPOSE:To exclude pulses which has low reliability and to improve signal analysis accuracy by giving each pulse importance evaluation marks corresponding to the importance of pulse data and providing a threshold value based upon the evaluation marks by a pulse classifier. CONSTITUTION:An importance evaluating device 2 calculates evaluation marks of each pulse by using pulse width detected by a pulse item detector 1. Every time a pulse with similar pulse width is inputted, the evaluation marks are increased and then evaluation is lowest for an unprecedented pulse and becomes higher as pulses are accumulated by the scanning of a radar. Threshold values based upon evaluation marks are prepared in the pulse classifier 3 and set properly, and consequently a group containing accurately measured pulses more is made effectively earlier and processed. Namely, a pulse group modulator analyzer 4 analyzes the center frequency, frequency range, and frequency modulation of each pulse group and stores the result in a storage device 5.

Abstract: PURPOSE:To enable ternary recording to be performed with two kinds of dots on a single disk, by a method wherein an optical recording medium having a recording layer comprising a polydiacetylene derivative and a pyrylium dye is irradiated with light, the light exposure being controlled according to recording information. CONSTITUTION:Recording information is converted into an optical signal by a semiconductor laser through a controlling circuit. The optical signal is led through an optical system to a predetermined position of an optical recording medium, thereby forming an image.

At the point 3a supplied with the light exposure Q1, the polydiacethylene derivative is heated by the heat generated by a pyrylium dye, resulting in a color change to red and formation of a dot 5a. At the point 3b supplied with the light exposure Q2, the layer 2 at this part is melted, whereby a pit consisting of a recessed part 5b is formed.

Title: Method and apparatus for inspection of mold
Inventor: HOSHINO ETSUHISA
IPC: B22C9/00
Filed: 1979-02-14
Abstract: PURPOSE: To surely and rapidly detect only the correct molds and safely produce the good castings by detecting the fluctuations in the pressure of the fluid flowed into the molds prior to casting.  
     CONSTITUTION: For the mold 1 having a molding part cavity 6, a main nozzle 10 is connected to the upper part of the well 2 communicated with a sprue 3 and a sub-nozzle 20 is disposed to the upper part of the well 4 communicated by a detecting cross gate 5. A pressure fluctuation detector 30 is connected to the sub-nozzle 20. The fluid 12 spouted from the main nozzle 19 flows in the order of the well 2→sprue 3→molding part cavity 6→detecting cross gate 5→well 4 as shown in the arrows and flows outward through the sub-nozzle 20. On the other hand, the fluid 22 spouts like the arrow from the sub-nozzle 20 at the same instance. The two fluids 12 and 22 interfere with each other and produce pressure fluctuations in the sub-nozzle 20. By detecting these with the detector 30, the goodness or not of the mold 1 is judged. As the above-mentioned fluid, the use of pressured air of  about 0.2kg/cm 2  and about 0.05W0.1kg/cm 2  respectively is satisfactory.

Title: Liquid application valve
Inventor: KOSOTO MASANORI
IPC: F16K23/00
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To eliminate the necessity of regular removal of air bubbles inside a valve by forming a valve opening/closing valve so that it nears the exhaust part of a valve so as to prevent liquid dripping. SOLUTION: A nozzle is formed with a metal part 3 and a synthetic resin part 4, and an opening/closing valve 2 of which top end is sharp is brought in contact with the synthetic resin part 4 of the nozzle so as to form the opening/closing valve 2. With this constitution, even if air bubbles are produced in a valve 1, a pressure is always applied to the inside of the opening/closing valve 2. Therefore the air bubbles are always compressed and not expanded. As a result, it can be prevented that, in application, the air bubbles are compressed and the amount of discharge is reduced by a compressed volume or, after the application has been completed, the pressure inside the valve is reduced to the atmospheric pressure and liquid is flown out from a nozzle because the volume of the compressed air bubbles is returned back to its original volume.  Thus the air bubbles inside the valve does not need to be removed.
