Title: Measurement of switching characteristic of logic circuit element
Inventor: HISHINUMA TAKEO
IPC: G01R31/26
Filed: 1983-07-13
Abstract: PURPOSE:To enable an efficient measurement for a short required measuring time by a method wherein the timing of an input pulse is measured in the combination of coarse and precise scores for the first time and all or apart of the coarse scores are eliminated following the second time. CONSTITUTION:When measuring a logic circuit element, the score in the adjusting step of the timing is divided in two, coarse and precise, one. The measuring is done at the adjusting step mt of the timing with the coarse score, for example, of (m) mold in the first half of the measurement. In the second half thereof, the adjusting score of the timing is controlled to be made precise by the minimum unit (t) to perform a measuring and regarding the measurement start timing, it following the second time is determined based on the actual measured value in the preceding measurement to reduce the measuring time. Thus, an efficient measurement can be done for a required measuring time without affecting the measuring accuracy by switching the measuring speed.

Abstract: PURPOSE:To effectively prevent effective gate length from shortening in a semiconductor device by interposing a first conductive layer, having impurity concentration lower that of a second conductive layer, between a first impurity region and the second conductive layer. CONSTITUTION:n<+> impurity injected layers 3a, 3b and a gate electrode 6 constitute a MOS transistor, a polysilicon film 13a and a silicide film 13b constitute a bit line 13, and a capacitor dielectric film 10 and upper/lower electrodes 11, 9 of capacitor constitute a stacked type capacitor. An epitaxial silicon layer 8 having lower impurity concentration is interposed between the n<+> impurity injected layer 3b and the lower electrode 9 of capacitor 9 and then it is subjected to heat treatment in order to suppress diffusion of impurities from the lower electrode 9 of capacitor to a single crystal silicon substrate 1. Consequently, degree of diffusion in an n<+> impurity diffused layer 4 lowers even if it is subjected to heat treatment for flattening of about 850 deg.C ALACC without causing shortening of effective gate length, resulting in effective prevention of short channel effect.

Title: Data recording camera
Inventor: YOSHIDA YUTAKA
IPC: G03B17/24
Filed: 1995-05-26
Abstract: PURPOSE: To make it possible to execute data recording at a stable recording density by preventing the fine fluctuation in recording density. CONSTITUTION: The rotating period of a motor 11 is detected by an encoder 40 and ENC pulses are generated from an encoding pulse generator 41. A slight fluctuation removing section 43 converts the respective pulse periods of ENC pulses to voltage and passes the voltage through a low-pass filter. After the voltage is converted to the pulses of the pulse periods corresponding to the voltage of the resulted signal, the pulses are sent to a total pulse counter 45 and a pulse interval measuring counter 46. This pulse interval measuring counter 46 measures the pulse period tn from the slight fluctuation removing section 43 and sends the pulse period to a multiplier 48. This multiplier 48 inputs value TW obtd. multiplied by a coefft. K and the pulse period tn to a timer 49.  This timer 49 frequency-divides a basic clock by the value TW and sends the pulses of the period TW via an AND circuit 50 to a shift register 51. This shift register 51 sends data by each one bit to a head driver 52 at every timing of these pulses. A magnetic head 30 changes over the writing data at this timing and successively magnetically records the data to a magnetic recording layer 20.
