Title: Separation of semiconductor wafer
Inventor: ABE MASAYASU
IPC: B28D5/00
Filed: 1980-06-17
Abstract: PURPOSE:To prevent crackings and spallings in a pellet separated by spraying a fluid under a specified pressure to a separating groove provided on the surface of a wafer after it is fixed on an adsorption plate provided with fine sucking holes. CONSTITUTION:Separating grooves 12, 40-100mum wide and 200mum deep are formed with a diamond cutter, for example, on a wafer 11 comprising a plurality of pellets 10 along separating regions. The wafer 11 is drawn by vacuum and fastened on an adsorption plate 15 with a plurality of sucking holes 1 ranging 10-100mum in diameter. The tip of a nozzle 16 about 100mum in diameter approaches right above the grooves 12 on the wafer 11 and blows an N2 gas thereto under a pressure of 10kg/cm<2>, for example while moving along the grooves.

Title: Presetting system for television tuning voltage
Inventor: HAGIWARA YOSHIMUNE
IPC: H04N5/44
Filed: 1978-07-07
Abstract: PURPOSE: To shorten the time required for presetting operation by making a voltage adjustment with gradual approximation to a tuning voltage point when presetting a tuning voltage to a memory.  
     CONSTITUTION: The voltage memory, having a length of approximate 12 bits, takes such time to find a tuning point by changing data, bit by bit. For the purpose, the tuning voltage point is obtained according to the steps mentioned hereafter. In step 1, a voltage (the largest of voltage differences between adjacent channels) equivalent to (n i ) bits is given. If tuning to a desired station is unsuccessful, a voltage is further applied as high as (n i ) bits in step 2. when the tuning to the desired station is done in variation in voltage in step 2, the voltage is reduced by n i /2 in step 3. When the desired station is found in variation in voltage in step 3, the voltage is increased by n i /4 in step 4. In this way, approximation to the desired tuning voltage is attained. An interruption pulse is generated at the tuning point during the variation.

Title: Mixer circuit
Inventor: TANABE KENZOU
IPC: H03D7/12
Filed: 1983-05-10
Abstract: PURPOSE:To obtain a mixer circuit having an adder circuit free from loss, no interference between a local oscillation signal and a high frequency signal by taking out an IF signal from the drain of an FET for mixer. CONSTITUTION:Two FETs 16, 17 having the same characteristics are used. The source S of the FET 16 is grounded and the drain D is connected to the source S of another FET 17, and the drain D of the FET 17 is connected to a power source Vcc. Thus, a so-called cascade type connecting system is adopted. By this way, the drain current of FETs 16, 17 are equalized, and a DC bias voltage that flows the drain current to the gates of FET 16, 17 is applied. At the same time, a high frequency signal is applied to a gate G, and a local oscillation signal is applied to another gate G, and a signal obtained by adding the two signals is obtained from the junction of drain sources of FETs 16, 17. By applying this signal between gate sources of a J-FET 10 used as a mixer, an IF signal is obtained from the drain side.

Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To open or close a sliding door by a motor after the completely opened or closed sliding door has been manually opened or closed to a specified position. SOLUTION: When a sliding door is manually driven to the opening direction from the completely closed state, the on-signal of a sliding door curtain switch 13 and the off-switch of a half-latch switch circuit 26 are input in a logical circuit 2. An electrically opening signal is output on the basis of the on-signal and the off-signal in the logical circuit 2. By this electrically opening signal, the sliding door is transferred to the opening direction. When the sliding door is manually driven from the completely opened sate to the closing direction, an off-signal of the completely opening switch 12 is input in the logic circuit 2. The off-signal of the completely opening switch 12 works as a trigger and the pulse number generated by the first speed sensor 10a is counted by the logic circuit 2.  The sliding door is transferred to the closing direction by the count signal at the time when this pulse number is counted three for instance.
