Title: Semiconductor memory unit
Inventor: SASAKI NOBUO
IPC: G11C5/06
Filed: 1978-11-14
Abstract: PURPOSE: To prevent the access time of RAM from shortening by interposing an amplifier between respective word lines switching transfer gates of RAM composed of silicon sapphire (SOS) MOSFETs.  
     CONSTITUTION: Random-access memory RAM consists of FF1 of SOS CMOSFETs 1a and 1b and trasfer gates 2a and 2b of SOS MOSFETs, and respective gates 2a... and 2b... of RAM are simultaneously controlled through work lines 3. Between those lines 3, amplifier 7 composed of two inverters 7a and 7b connected together is interposed and when driving terminal 5 of line 3 is held at a driving potential, the output distribution of inverter 7a decreases gradually by the delay network of RAMs down to a threshold voltage, where inversion is caused to hold momently the output of inverter 7b at the driving potential, thereby making gates 2a and 2b conduct before delaying. Therefore, the access time of RAM never shortens even if the gate insulation film of SOS MOSFET is thinned in order to increase the operation speed of FET.

Abstract: PURPOSE:To raise the ground surface gripping efficiency of a pneumatic tire while steering, by forming offsets of a given size in the circumferencial direction between the blocks on the tread which are adjoining each other along the rotary shaft direction of the tire, and arranging them as they form a herringbone pattern at a specific angle of inclination to the rotary shaft. CONSTITUTION:For example, between two lines L-L, M-M, which are parallel with the rotary shaft direction line J-J, the former passes through the center of gravity G of a block B'1 which is formed at the left side of the equator O-O, the latter passes through the center of gravity G of a block B'2 which is formed at the left side of the said block B'1, an offset x, whose length is 0.3-0.7 times the circumferential length A of the block, is formed. Then, from the center of the tread toward the edge of it, blocks B... are arranged as they form a herringbone patterned blocks line at an average angle of inclination of 10-35 deg. with the rotary shaft direction line J-J. Consequently, a decrease of the ground surface gripping efficiency, caused by the lateral force which is given while the steering and the turning, can be prevented and the driving efficiency can be raised, by forming all block lines in the said method.

Title: Slip feed controller
Inventor: FUKUSHIMA ITARU
IPC: G06K13/077
Filed: 1982-08-13
Abstract: PURPOSE:To obtain automatically the best condition for the feed interval of a slip, by driving intermittently a motor by a timer after estimating the processing time needed for a sheet of slip and feeding intermittently the slip. CONSTITUTION:When a slip feed controller is started, the slips 101 on a hopper 100 are fed one by one by a belt driven by a motor 103. A motor 108 is also started simultaneously, and the motor 103 stops when the tip of the slip 101 is detected 104. However the slip 101 is carried to a reading part by a belt 106. The feed motor 112 of the reading part is equal to a stepping motor and drives intermittently a belt 111 synchronously with reading operation. A counter (not shown in the figure) measures the time during which the tip of the slip 101 is detected 109 and then the rear edge is detected 110. This measured value is stored, and the motor 103 is driven intermittently based on the data of the stored measured value. Thus the subsequent slips are fed successively. When the processing time is increased, motors 103 and 108 are stopped until the rear edge of the slip is detected 110. This ensures smooth and automatic feed of slips.
