Title: Hysteresis circuit
Inventor: UNO KENJI
IPC: H03K3/023
Filed: 1990-08-30
Abstract: PURPOSE:To facilitate the electric external control and to miniaturize an element by constituting an input resistance part of two MOS transistors TRs connected in series and inputting pulse signals having compelmentary phases to gates of these MOS TRs and connecting the middle connection point between these MOS TRs to one end of a capacity. CONSTITUTION:An input resistance part 1 is provided instead of a conventional input resistance. In the input resistance part 1, a series circuit of two MOS TRs T1 and T2 is inserted between an input terminal and the negative feedback input terminal of an operational amplifier OP, and one end of a capacitor C which has the other earthed is connected to the connection point of these TRs, and external pulses phi and the inverse of phi which have a period T and have complementary phases are supplied to respective gates. That is, the equivalent resistance value of the input resistance part 1 is set to T/C by the change of the pulse period T to change the amplification factor, and external control is performed by the change of the period T, namely, the frequency of the external pulse. Thus, the electric characteristic is easily tested to design the element in a small size on constitution.

IPC: G11B23/087
Filed: 1990-08-29
Abstract: PURPOSE:To reduce occupancy space at the time of use by rotating a pair of covers and a pair of arms as synchronizing them with each other, and stretching a magnetic tape by a pair of the arms at the outside of a tape cassette main body. CONSTITUTION:A pair of the covers 2 and 3 are fitted freely rotatably to a tape cassette 1 consisting of an upper half 1a and a lower half 1b as being energized to a closing direction in form to cover the front part of the tape cassette 1. Besides, the arms 4 and 5 are fitted freely rotatably to the inside surface of the upper half 1a while being energized to the closing direction, and the arms 4, 5 are rotated while being nearly synchronized with the rotation of the covers 2 and 3 by anchoring the arms 4 and 5 by connecting members formed at the covers 2 and 3. Accordingly, open space for inserting a tape draw-out member to wind the magnetic tape 6 around a drum can be formed by moving it from a first position where it is stored in the cassette main body to a second position outside the cassette main body, and it can be loaded to a magnetic tape device. Thus, the occupancy space at the time of use can be made small.

Abstract: PURPOSE:To accurately detect the height of contents with a high resolution by emitting light between light emitting devices separated at least by two in a height direction and detecting the height of the contents based upon an output from an optical detection device which detects the light emission from said light emitting devices. CONSTITUTION:Light emitting devices (LEDs,for example) Da-Dg separated at least by two in a height direction emit light in order, and outputs from optical detection devices (phototransistors, for example) provided oppositely to the light emitting devices Da-Dg are read into control means (microcomputer) 4 for detection of the height of contents. Hereby, the outputs from the optical detection devices Qa-AQg are prevented from being affected by another light emitting device adjoining to the opposing light emitting devices Da-Dg, and accurately detect the height of the height of the contents with a high resolution. Further, since the affection of the other light emitting devices is eliminated, the need of taking longer an extinction time interval between light emission intervals between the light emitting devices emitting light in succession is obviated so that judgement time is shortened.

Title: Rice-polishing tank
Inventor: TAMEHISA EIJI
IPC: B02B7/02
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To reduce impact given to rice grains by the fall in a tank for polishing rice by decreasing the distance of the fall. SOLUTION: An inner cylinder 2 is installed in a rice-polishing tank 1, to make plural vertically-partitioned spaces with a common outlet. For example, in an initial stage of rice-polishing, rice grains are stored in the space of the inner cylinder and in the space between the inner cylinder and the rice-polishing tank, and with the progress of rice-polishing, the volume of rice grains becomes smaller, and accordingly, the distance of the fall becomes longer and the given impact becomes stronger. In such a stage, for example, that the ratio of polishing rice comes to 50%, if the rice grains are charged only into the space of the inner cylinder, the distance of the fall is decreased.  As a results, in the case of high-grade rice-polishing, the distance of the fall can be decreased, resulting in the reducing of the given impact, which is the cause for generation of cracked rice and broken rice.
