Title: Method for identifying metal mold in injection molding machine
Inventor: SHIMIZU MIYUKI
IPC: B29C41/00
Filed: 1982-03-15
Abstract: PURPOSE:To set the inherent molding conditions of the metal mold in a control device of an injection molding machine automatically, by providing marks inherent to the metal mold, detecting the marks by the device on the injection molding machine, and identifying the metal mold. CONSTITUTION:To the identifying part of a metal mold 21, a fixing side attaching plate 24, wherein four screw holes 1, 2, 4 and 8 are laterally provided at the outer upper part, is fixed. Pins 26, which are screwed into the screw holes, serve as the marks indicating the inherence of the metal mold 21. The identification is performed when the fixing plate 24 is attached to a fixing board 27 on the side of the injection machine. A detecting device 29 is provided at a part corresponding to said identifying part. When said fixing side attaching plate 24 is fixed to the fixing board 27, the pins 26 in the screw holes 4 and 8 are inserted into members 14 and 18 (as illustrated) and this fact is instantly detected. Thus the identification is performed. The detection is transduced into an electric signal. The signal is transmitted from the control part to an external memory part, i.e. the molding conditions are transmitted. Errors found in conventional manual identification can be completely avoided.

Title: Thickness detector for sheet paper or the like
Inventor: TSUCHITANI NORIO
IPC: G07D7/182
Filed: 1987-02-26
Abstract: PURPOSE:To eliminate errors due to the wear of a roller and dust sticking on the roller by using thickness data which is the difference between the mean value of thickness detection levels when paper money passes and the mean value of detection levels in a specific period in the absence of paper money. CONSTITUTION:A gate sensor 10 detects the front end of paper money P from an A/D converter 20 in response to a signal from the sensor 10, and holds the value obtained by adding data until the paper P moves into between rollers 25 (until the sampling data increases abruptly to a large value) in a RAM 22 as initial integral value A. Further, the sum value of the sampling data from the entry of the a paper money P into between the rollers 2 and 5 to the point of time when the sampling data indicates small value suddenly is held as a thickness data integral value B in the RAM 22. Then B-A is calculated and then divided by the time zone of the data addition to find the real thickness.

Title: Pile with bag body
Inventor: SHIGEMATSU HIDEKAZU
IPC: E02D5/44
Filed: 1995-03-01
Abstract: PURPOSE: To provide a bag body pile provided with a bag at its top end which can be mounted with a simple band without applying large force on a band mounting part though the bag body can withstand a high pressure which expands particularly a fixed quality flowing matter. CONSTITUTION: A seamless cloth bag 11 of which both end parts 11a are formed in +0 to 100mm in pile outside diameter and of which center part 11b is formed in +100 to 600mm in diameter, that is, woven in different diameter, and which is not provided with a connection part is covered on the outer periphery of an existing pile 12 near the top end of it. Also the both ends 11a of the seamless cloth bag 11 are mounted with a band 14. By this, a risk of burst of the seamless cloth bag 11 from the connecting part is eliminated, the outer wall of the seamless cloth bag 11 is exhibitly strengthened sufficiently, and a required strength and fastening force of the band 14 can be reduced because any force raising the band does not act in the expansion of the bag body.  In addition, because the bag body does not contact with the projected part of the band even if it is expanded, there is no risk of burst of the bag body. Therefore it can be sufficiently expanded in lateral direction at a high pressure, and a higher supporting force of pile can be obtained.

Title: Fuel cell
Inventor: NAKAJIMA NORIYUKI
IPC: H01M8/02
Filed: 1990-02-22
Abstract: PURPOSE:To generate a power of equal voltage on every position all over electrodes by gradually increasing the amount of catalyst carried on electrodes from the intake side toward the outlet side of the electrodes to which reaction gases are supplied. CONSTITUTION:A fuel gas is supplied to a fuel electrode 14, and air is supplied to an air electrode 15 separately to each other, and these reaction gases electrochemically react through a matrix layer 11 to generate a power. In a fuel cell, the amount of catalyst carried on electrodes is increased gradually from the intake side toward the outlet side of the electrodes to which the reaction gases are supplied. Thereby even when hydrogen and oxygen contributing to the electrochemical reaction contained in the reaction gases are consumed with the reaction, so as that the concentration of them is decreased from the intake side toward the outlet side of the electrodes to reduce the output voltage, on the other hand, the amount of catalyst on the electrodes is inversely increased from the intake side toward the outlet side of the electrodes so as to elevate the output voltage, hence as a whole, the generated voltage can be made uniform all over the electrodes.

IPC: G08B17/10
Filed: 1988-02-26
Abstract: PURPOSE:To attain highly accurate calibration by automatically judging whether or not circumferential conditions are fit for the calibration before the detecting output of a fire phenomenon detecting part is calibrated. CONSTITUTION:For a detecting signal outputted by receiving the light emission of an LED with a solar battery SB, a tilt K of its level characteristics changes according to the circumferential conditions as shown in a figure. Before the tilt K is calibrated, it is decided whether or not the circumferential conditions are fit for calibrating action. A microprocessor MPU reads detected output levels VX at every 3 seconds for M pieces, and successively stores them to addressed 1-M of a detecting output data memory RAM 1. Further, the maximum level and the minimum level are stored respectively as Vmax and Vmin, and next, whether or not the difference between the both is a constant value or below is decided. When the difference is the constant value or more, it is regarded not to be fit for the conditions, and the calibration action is not executed, and a fire monitor action is continued. When it is the constant value or below, the calibration action, namely, a dirt correcting program to compensate for the change of the tilt K due to dirt is executed.
