Title: Automatic manuscript mount base
Inventor: HIROSE HIROSHI
IPC: B41J29/15
Filed: 1987-09-14
Abstract: PURPOSE:To maintain the position of a reading part to be constant and achieve feeding of a manuscript, by pneumatically transmitting the movement of a pedal to a main body of a manuscript mount base, and rotating in one direction a paper-feeding rotary shaft supporting a plurality of feeding rollers thereon. CONSTITUTION:When air is fed under pressure from an air compressor 11 to a driver 5 by stepping on a pedal 12 to pull a string 9 rightward along arrows A, a driving rotary body 6 is rotated counterclockwise, the rotation is transmitted through a clutch spring 14 to a driven rotary body 7, and further through a rotary shaft 3 to paper-feeding rollers 4, whereby a manuscript is fed by a predetermined line space. When the pulling of the string 9 is released, the string 9 is moved leftward along the arrows A by a return spring 8, thereby rotating the rotary body 6 in the opposite direction. In this case, the clutch spring 14 is slackened, so that it does not transmit a driving force to the driven rotary body 7, and the paper-feeding rollers 4 are not rotated. Therefore, it is possible to achieve an arbitrary manuscript feeding, with the rotation of the paper-feeding rollers 4 corresponding to the amount of stepping on the pedal 12.

Title: Digital delay circuit
Inventor: HAYAMA HIROSHI
IPC: H03K5/13
Filed: 1982-12-28
Abstract: PURPOSE:To obtain a digital delay circuit of low power consumption and possible for high speed access by storing a data in a memory cell and shifting physically an address signal to access the cell on a shift register. CONSTITUTION:Since the shift register 1 is branched at each clock, an address signal applied to the shift register 1 is propagated onto the branched address and one is connected to a read selecting line of each bit as it is and the other is connected to a write selecting line after being subject to a delay for 1 clock's share. Thus, a bit one clock after the read of the bit is written. Since an address signal 7 is applied to the shift register 1 after the read/write for 4 bits' share is executed once more, the same operation is repeated again. Thus, a delay as much as four clocks' delay is given to a data of a memory section 2.

Filed: 1985-10-17
Abstract: PURPOSE:To measure the geothermal heat flow with a high accuracy by landing a temperature gradient measuring probe on the sea bottom approximately perpendicularly thereto and driving the probe into the sea bottom more deeply by means of the free drop of a weight. CONSTITUTION:When the body 10 of a terrestrial heat flow measuring system is submerged down to the sea bottom from a ship 13 floating an the sea surface 12, the body 10 is landed approximately perpendicularly to the sea bottom 8. Thereafter, when a temperature gradient measuring probe 3 is freely dropped, a heat is generated in the probing portion 3b of the probe 3 due to a friction between the probe 2 and the sea bottom 8 and the output of temperature sensing elements 5 driven into the sea bottom 8 among the elements 5 in the probing portion 3b is changed. Therefore, the number of the temperature sensing elements 5 whose output data are changed can be determined on the ship 13 and the penetrating depth of the probing portion 3b into the sea bottom 8 can be estimated. When the penetrating depth is judged insufficient, the lowest weight 4 is freely dropped whereby the probing portion 3b can be driven more deeply into the sea bottom 8. By further freely dropping the remaining weights 4 in sequence, a driving-in operation can be continued until the sufficient penetrating depth is obtained.
