Title: Measuring device for tidal current
Inventor: NAKATANI HIROSHI
IPC: G01D21/00
Filed: 1981-07-29
Abstract: PURPOSE:To detect tidal current signals with good S/N even when the signals are weak by removing the frequency shift components owing to ship speeds beforehand from underwater reflected waves, and drawing only the frequency signals including tidal current components. CONSTITUTION:Underwater ultrasonic wave signals are transmitted 2, and the signals reflected from the sea bottom and from the water are respectively received 3. In accordance with the differences in the Doppler effect that the respective reflected waves receive, the velocity of the tidal current is detected. Here, the waves reflected from the sea bottom are selected 6 from the reflected waves by utilization of the level differences between the waves reflected from the water and the waves reflected from the sea bottom. The signal of the waves reflected from the sea bottom and a locally oscillated signal 10 which is prepared beforehand are mixed 9. Further the mixed signals and the reflected waves are mixed 11. From the outputs of the mixed signals, the frequency components wherein the frequency of the signal 10 is shifted by the frequency associating with the preset max. velocity of the tidal current are drawn 12. The velocity of the tidal current is detected 17 by the use of the waves reflected from the water and the waves reflected from the sea bottom.

Title: Storage of diazomethane derivative
Inventor: KOUNO KORETOMO
IPC: C07C245/14
Filed: 1983-06-30
Abstract: PURPOSE:To store the titled compound useful as a carboxyl-protecting group of organic compounds, easily, at a low cost, in high stability, by mixing a diazomethane derivative with methylene chloride at a specific ratio, and storing the mixture at a specific temperature. CONSTITUTION:The diazomethane derivative of formula (R1 and R2 are substituted or unsubstituted aromatic group) is mixed with methylene chloride at a weight ratio of (100-25):(0-75), and stored at -25-+15 deg.C, preferably, -20- +10 deg.C. Although diazomethane derivative is useful as a protecting group of the carboxyl of organic compounds, it is decomposed extremely easily, for example, diphenyldiazomethane is decomposed to ketazine when left at room temperature for 2 days, and the purity decreases to 75% of the original purity. It has been found that the decomposition rate of the compound can be decreased remarkably when the diazomethane derivative is stored in a state containing at least part of the diazomethane derivative in the form of crystal and in the presence of methylene chloride.

Title: Transmission circuit for clock signal
Inventor: SATO JUNICHI
IPC: H04L7/04
Filed: 1990-05-11
Abstract: PURPOSE:To prevent an adverse effect without additional defect by clamping a signal voltage with a remote end clamping circuit and constituting a series circuit between a resistor and a capacitor of a remote end receiver so as to attain integration operation. CONSTITUTION:When a voltage higher than a signal voltage at a clamping circuit 4 due to the reflection of a clock signal is generated, a higher portion than the signal voltage is sent to a power supply side or a ground side, and the level of the clock signal is clamped to a signal voltage level. Thus, independently of the impedance of a clock signal transmission circuit 5, the level of the clock signal is fixed to a signal voltage. Moreover, the impedance of a remote end receiver 2l in the case of viewing from a quasi-remote end receiver 2ll is decreased to the resistance of a resistor 6 from an infinite value by the provision of the resistor 6. Thus, nonlinear reflection is suppressed. Thus, the adverse effect of reflection is avoided without additional defect such as susceptibility of effect of a temperature change or deteriorated high frequency response.

Filed: 1991-05-27
Abstract: PURPOSE:To obtain a rapid circuit operation by eliminating the deformation of a source and a drain region due to the conversion into metal silicide, in a thin-film SOI MOS transistor. CONSTITUTION:In order to convert an island semiconductor thin film 34 formed on an insulator 33 into metal silicide to the depth to reach the insulated film, a base, an insulated film-formed side wall 64 is formed on the side face of the island first and then the island semiconductor thin film is coated with a metal layer. By forming the insulated film-formed side wall on the side face of the island of the semiconductor thin film, the supply of metal from the side face, a main cause of the deformation due to the conversion into metal silicide, is prevented. And, the deformation is prevented by advancing the conversion into silicide uniformly. By this method, silicide is generated uniformly in a thin-film SOI MOS transistor. And, silicide can be generated without deformation of a source and a drain region and a rapid circuit operation is achieved.

Abstract: PURPOSE:To prevent the peeling of sputtering formed deposits in the process of sputtering by projecting an erosion part having a flat ring shape in a sputtering face to a nonerosion part and respectively specifying the surface roughness of both parts. CONSTITUTION:An erosion part 1 having a flat ring shape in a sputtering face is protruded to the remaining nonerosion part constituted of the central part 2a and outer circumferential part 2b in the sputtering face. Then, the surface roughness of the erosion part 1 is regulated to 0.01 to 0.05mum Ra (center line average roughness). Moreover, the surface roughness of the nonerosion parts 2a and 2b is regulated to 0.2 to 2mum Ra. The erosion part is made high by 0.05 to 5mm by face height than the nonerosion part of the central part in the sputtering face. The nonerosion part of the outer circumferential part is formed into a chamfered face. In this way, the frequent occurrence of particles in the process of film forming can be suppressed over a long period even by sputtering under severe conditions.

Filed: 1993-05-24
Abstract: PURPOSE:To make the capacity of slow cooling adjustable and to improve the accuracy of coiling temp. by movably arranging an impeller type spraying device right under an upper laminar nozzle. CONSTITUTION:By oerating an operating rod 3, the impeller 1 is moved in the position shown by chain line. The laminar flow of cooling water which flows out of the nozzle 6a of a laminar pipe 6 is broken with the impeller 1 and sprayed cooling function is lowered, so a strip 8 which is transported on table rollers 7 is slowly cooled. On the other hand, in the case of executing ordinary laminar cooling, by returning the operating rod 3 and situating the impeller 1 in the position shown by continuos line, the impeller 1 is deviated from the laminar flow from the laminar pipe 6 and cooling by the laminar flow is possible. The tip nozzle of a compressed air line 5 is made so as to touch the vanes of the impeller 1 and, in this way, by arbitrarily adjusting the number of revolution of the impeller 1 by changing the pressure and flow rate of compressed air and changing the spray range, the cooling function is adjusted.
