Patent JP-S61255597-A (JP)
Title: Nonvolatile semiconductor memory device
Inventor: IWAHASHI HIROSHI
IPC: G11C16/06
Filed: 1985-05-07
Abstract: PURPOSE:To completely enhance a reading margin without depending on a power source potential by comparing with a predetermined comparison potential to detect the data of a double gate type ROM element. CONSTITUTION:A floating gate of a transistor Mc of a potential generating circuit 30 of a comparison potential generating circuit 20 is brought to a neutral state. A potential variation owing to a variation of a power source voltage Vc of a nodal point Bc is equivalent to a cbange of a potential VBa1 owing to the variation of a voltage VCC of a nodal point Ba when ROM cells M11-Mmn of a double gate transistor in which the floating gate is brought to the neutral state. Similarly, the potential of a nodal point Bd of a comparison potential generating circuit 40 is equivalent to the variation of a potential VBa2 of the nodal point Ba when the cells M11-Mmn in which an electric charge flows in the floating gate. These nodal points Bc and Bd are connected by the transistor of a resistance component. A potential of a comparison voltage output nodal point D to a sense amplifier SA goes to an intermediate value of the potentials VBa1, VBa2. The reading margin of the ROM becomes high without depending on the power source potential.

Title: Joining method for plated strip steel
Inventor: MASUHARA HIROMI
IPC: B23K11/16
Filed: 1986-04-24
Abstract: PURPOSE:To stabilize a welding and to improve the efficiency in the operation by sliding a grinder on the peripheral face of a welding electrode wheel, by making the welding current intermittent and alternately forming respectively the weld zone and non-weld zone in the specified length. CONSTITUTION:The grinder 2 abutting to the peripheral face of an electrode wheel 1 and rotating in the reverse direction to the rotary direction of the electrode wheel 1 is provided and the plated metal, etc. adhered on the surface thereof are removed in the rolling and welding stages of the electrode wheel 1. In this case, a weld zone H is formed in 10-60mm length and non-weld zone C in 2-20mm length in the width direction of the overlapping face of strip steel 10, 11 by the ON, OFF control of the welding current. The cooling effect is improved by alternately transferring the non-weld zone C to restrain the adhesion of the plated metal located on the surface of the electrode wheel 1. In this way, therefore, the incomplete welding, etc. based on the variation in the welding current values are eliminated and the welding is stabilized. Moreover, the plated metal removing stage becomes disused and the operation efficiency is improved.

Title: Measuring instrument for percentage of water content of circulation type grain drier
Inventor: KANEFUJI YUUJI
IPC: G01N27/12
Filed: 1978-08-08
Abstract: PURPOSE: To improve the measurement precision of the percentage of water content by measuring the density of grains circulating in a drier in parallel to the measurement of the percentage of water content on a high-frequency system and then by correcting the output of the electrode plate for the total percentage of water content by the measurement output.  
     CONSTITUTION: In cylindrical measurement chamber 20, measuring cylinder 21 for the total weight and electrode plate 22 for the total percentage of water content are vertically arranged and the diameter of the center part of measuring cylinder 21 is made longer than those of its top and bottom openings so as to allow grains right before and after passing through electrode plate 22 to stay temporarily inside of measuring cylinder 21. By a load on measuring cyclinder 21 at this time, the density of grains passing through measuring cylinder 21 is measured and the output of the total percentage of water content is corrected by the measurement output. Therefore, even if the electrostatic capacity of electrode plate 22 varies with the density of grains circulating in drier 2, the invariably-accurate measurment of the percentage of water content can be done and grains can accurately be dried to a desired percentage by controlling drier 2 according to the measurement.
