Title: Semiconductor memory device
Inventor: YAMAMOTO MAKOTO
IPC: H01L27/10
Filed: 1988-05-31
Abstract: PURPOSE:To simply find out a memory cell even when a memory capacity is increased by a method wherein an interval in parts used as wiring parts of a gate electrode material inside a memory array is narrowed or widened every several wiring parts. CONSTITUTION:An interval in parts used only as two or more wiring parts, of a gate electrode material, arranged in a line direction or a row direction inside an insulated-gate type semiconductor memory array arranged in a matrix shape is narrowed or widened regularly every two or more wiring parts. At the inside of the memory array, a source line 21 used to take out a reference potential of a memory cell 3 is arranged every several lines of bit lines 20, and a memory cell is not formed under the source line 21; accordingly, word lines 10 in the part are used as wiring parts; even when an interval of the word lines 10 in the part is narrow, an electrical characteristic of the memory cell is not influenced at all. By utilizing this, e.g., parts 11 where the interval of the word lines 10 is narrowed every four lines are installed as marks as shown in the figure.

Title: Controller for vari-focal lens
Inventor: HATA DAISUKE
IPC: G02B7/10
Filed: 1987-05-30
Abstract: PURPOSE:To correct a shift in image formation position due to the update of the focal length of the whole system characteristic to a vari-focal lens by simple constitution stably at a high speed by driving a focusing lens group to a corrected focusing position according to a correction execution signal. CONSTITUTION:A comparative decision part 13 compares its internal set reference value with a correction quantity based on focal length information and outputs the execution signal GO, correction quantity Dfp, and focusing direction information when the correction quantity exceeds the reference value. Consequently, a focus control part 5 compares the output of a focus counter 6 with the correction quantity Dfp successively to drive the focus lens group 3.

Title: Acs circuit equipped with burst control circuit
Inventor: SHIINO SO
IPC: H04L27/22
Filed: 1987-05-29
Abstract: PURPOSE:To extremely reduce the hardware quantity by recognizing an overflow via an adder so that the same hardware constitution is possible to all ACS (addition/comparison/selection) circuits. CONSTITUTION:The generation of overflows due to additions are granted and a pass metric to be essentially selected is selected based on the output of a comparator 11 and the overflow information 13 and 14. At the same time, the state metric updated by an external control signal is forcibly set at the maximum value. Thus it is possible to decrease the number of bits showing both pass and state metrics and to realize a burst action by the forcible selection. Then the total number of internal and input/output bits of an ACS circuit is decreased and the same circuit constitution is available to all states. As a result, the hardware quantity needed for a Viterbi decoder can be extremely reduced.

Abstract: PURPOSE:To perform rapid switching of operation and non-operation without malfuction, by mounting a check ball in a high-pressure chamber and installing a rod, operated by an electromagnetic mechanism, to a low-pressure chamber. CONSTITUTION:During usual operation, a hydraulic oil is fed through the working of a pump 27 by forcibly pushing down a check ball 19 in a high-pressure chamber 14, the check ball 19 closes a valve seat 15 with a difference in pressure between the high-pressure chamber and a low-pressure chamber 13 through which the hydraulic oil is discharged to a discharge passage 31, a hydraulic tappet 9 is secured, and a suction and exhaust valve 6 is vertically moved through rotation of a cam 10.
