Title: Method for preventing edge overcoating of hot-dipped steel sheet
Inventor: ANDO KOJI
IPC: C23C2/20
Filed: 1988-05-19
Abstract: PURPOSE:To prevent the edge overcoating of a hot-dipped steel sheet by provid ing plural guide vanes in the main nozzle for injecting a gas, and making the injecting direction variable in accordance with the distance between the nozzle and the steel sheet and the width of the steel sheet. CONSTITUTION:A steel sheet 1 to be plated is continuously supplied into a hot-dipping soln. 2, and drawn out through rolls 3. A gas is injected from the main nozzle 4 to appropriately remove the excess of the soln. 2 deposited on the steel sheet 1. At this time, plural guide vales 5a-5g are provided in the main nozzle 4 to optionally vary the injecting direction in accordance with the distance Da between the main nozzle 4 and the steel sheet 1(1a) and the width Ha of the steel sheet 1. Under such a constitution, the gas currents be tween the vanes 5a and 5b and between the vanes 5b and 5c are directed inward from the edge part of the steel sheet 1a. By this method, an increase in the amt. of the soln. deposited on the edge part is obviated, and overcoating is prevented.

Title: Recording and reproducing device
Inventor: KAKIMURA YOSHIAKI
IPC: G11B15/467
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of reproduced signal quality caused by reverse track reproduction by performing azimuth management for each recording track in a VTR for recording a video signal of one field in each inclined track by two rotary heads different from each other in azimuth angle. SOLUTION: A video signal of one frame is recorded in each inclined track by two rotary heads having different azimuth angles. Control pulses having duty ratios alternately changed one from the other are recorded for each inclined track. During reproducing, based on a relationship between the duty ratio of a reproducing control pulse and a pulse synchronized with the rotation of the rotary head, whether the reproducing rotary head is for reverse track reproduction or not is determined, and if the reverse track reproduction is determined, the operation is automatically correct to correct tracking by controlling the rotation of a capstan motor 12.

IPC: A61B5/0245
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To provide a pulse wave detection device capable of detecting pulse wave with a small power consumption, and extending the service time. SOLUTION: An ultrasonic wave f0 of 10 MHz in frequency is transmitted from an ultrasonic transmitting means 11 to an artery 2, and the frequency- modulated reflecting wave f1 is received by an ultrasonic wave receiving means 21. This reflecting wave f1 is subjected to the FM detection, and the pulse rate is displayed. The ultrasonic wave is transmitted for 10 seconds by the intermittent drive of an intermittent operation control means 12 to measure the pulse rate, and then, stopped for 50 seconds. The display of the pulse rate while stopping the measurement is replaced by the measurement immediately before the measurement is stopped. By intermittently driving the ultrasonic wave transmitting means 11, the power consumption is reduced, and the means can be mounted even on a portable device compact and small in battery capacity such as a watch, and can be used for a long time.  When a bodily motion is detected by a bodily motion detection part 13 and a pulse rate fluctuation judgment part 14, the transmission of the ultrasonic wave for 10 seconds is re-started.

Filed: 1978-10-09
Abstract: PURPOSE: To prevent the lowering of the characteristics and yield of Si and SiO 2  due to thermal distortion, by preventing the cracks of an oxidation preventive film by establishing a region with no oxidation preventive film to a surrounding portion of a unit pellet.  
     CONSTITUTION: A region 20 with no Si 3 N 4  18 is installed around a unit Si pellet 15, continuity with Si 3 N 4  among adjacent pellets is intercepted, and the concentration of distortion among Si 3 N 4  and Si to a specified unit pellet is obviated, thus equalizing the magnitude of the strain of pellets under an arranged condtition. When the region 20 is formed in sufficiently minute small area, distortion is little if SiO 2  is made up to the region 20. When the region 20 is disposed at a location that does not agree with a position to be cut, cutting workability is improved because the increase of the thickness of SiO 2  at the position to be cut is prevented. The characteristics of this device and yield do not deteriorate because the cracks of si 3 N 4  can be obviated even when a plurality of unit pellets are arranged by this constitution and thermal distortion among Si and Si 3 N 4  can be reduced.
