Abstract: PURPOSE:To detect the generation, access or passage of a quicksand or to enable measurement of the amount of the quicksand, by providing a tubular body in a flowing water area to perform a signal pressing of an acoustic signal generated when a quicksand impacts it, after converted into an electrical signal. CONSTITUTION:An acoustic sensor in which an acoustoelectric signal converter, for example, a small microphone 2 is placed into a tubular body such as steel pipe 1 provided with an acoustic characteristic that is preset by selecting a material and dimensions to be selective with respect to sound attributed to a quicksand and sealed with sound absorbing material 3 and 3 at both ends thereof is set in a flowing water area. A sound as generated when a water flow or a quicksand hits the pipe 1 is analyzed to measure the amount of the quicksand of a relatively large particle moving near a river bed 4. The water flow runs in the direction of the arrow. It is desired that the pipe 1 should be set on a fixed bed to maintain setting conditions thereof constant. It should be noted that the steel pipe 1 is arranged in plurality in the direction of cutting the water flow horizontally and vertically to achieve a higher accuracy of measuring the amount of the quicksand.

Title: Fuel feeder
Inventor: EBIHARA YOSHIO
IPC: F02M37/00
Filed: 1983-09-19
Abstract: PURPOSE:To eliminate the need for high pressure performance of fuel pump by feeding the air pressure at the downstream of supercharger directly to fuel tank. CONSTITUTION:The air pressurized by a turbocharger 2 is fed through a pressure transmission piping 3 into a fuel tank 5 to pressurize it. Consequently, the differential pressure PA-PB between the fuel intake port B in fuel tank 5 and section A to be fed with engine 6 fuel from a carburetor 7 is produced by the fuel pump 4 irrespective of the pressurizing force of turbocharger 2. Consequently, it is not required to increase the delivery pressure of fuel pump for engine having turbocharger.

IPC: H01L23/02
Filed: 1981-10-29
Abstract: PURPOSE:To realize perfect package sealing and cost reduction by plating a noble metal only to a single side of the sealing metal plate and also plating a noble metal to the cutting area of the bridging member. CONSTITUTION:A package sealing metal plate 22 of the specified pattern is formed in continuation on the opposed belt-shaped metal plate 21 through a bridging member 23. At the rear surface of this member 23, a cut-away groove 101 is formed. After executing the Ni plating to the entire part of a sheet of metal member in such a condition, the Au plating is executed only to a single side opposing to a groove 101 of the metal sheet. Successively, the member 23 is cut at the groove 101. Next, the Au plated area 24 of package sealing metal plate and a sealing agent 25 provided on the ceramic substrate are heated and fused, in order to seal the package. At this time, the side B of package sealing metal plate is also sufficiently Au plated and accordingly the alloy of sealing agent fuses and extends up to the side surface A. As a result, perfect sealing can be obtained. In addition, a manufacturing cost for Au plating can be reduced because of a single side processing.

Abstract: PURPOSE:To improve air velocity distribution and to reduce incurring of a pressure loss, by a method wherein an impeller, formed with turbo type blades and a propeller type blade, formed in a specified shape and attached to the upper and the lower surface of a main disc, respectively, is mounted to an electric motor, and the upper end of an inner guide is positioned to the outer peripheries of the turbo type blades. CONSTITUTION:Plural turbo type blades 2, the outlet angle of which is changed in an axial direction, are located to the upper end of a circular main disc 1 having a central part formed in a recess in cross section, a propeller type blade 3, provided at its outer peripheral part with a bent part 13 and having a size smaller than that of the main disc 1, is attached to the under surface and the outer peripheral part of the main disc 1 to form an impeller, which is mounted to an electric motor 4. Further, an inner guide 7 formed in a semicircle in cross section is so situated that its upper end is positioned in the level of the outer peripheries of the turbo blades 2. This constitution causes air to circumferentially outgo to the outer periphery of each of the turbo type blades 2, divides the flow of the exhausted air by means of outer and inner guides 5 and 7. The air guided by the inner guide 7 is further induced to a central part to uniformize exhaust air velocity distribution. Additionally, by changing the outlet of the turbo type blade 2 in the direction of an axis, incurring of a pressure loss is decreased.

Title: Image recorder
Inventor: MOGI YUJI
IPC: H04N1/06
Filed: 1988-07-13
Abstract: PURPOSE:To determine a stable drum origin or printing start point by easily adjusting only an electrical means by a construction wherein a reference point on a cylindrical drum can be moved to an arbitrary position on the periphery of the drum without varying an effective recording length. CONSTITUTION:A signal BL is a pulse signal forming a recording blanking part corresponding to a value (ld-lp) with a drum periphery length ld and a maximum effective recording length lp of a recording medium set to a drum. Therefore, a new main-scan printing is started every time when the signal BL turns from a period BL=H (a blanking period) to a period BL=L. On the other hand, a signal LA formed by a latch, a counter 10, a dip switch 12, and the like and driven at the timing of a signal REZ2 can start the signal BL according to an origin of an encoder (to which the signal REZ2 itself is corresponding) at an arbitrary position on the periphery of the drum (a resolving power is determined by a clock REA2 to be inputted to the counter 10). In this manner, only by adjusting the dip switch 12 for varying the count number of the counter 10, an arbitrary position on the drum can be determined as a recording start point.

Title: Refrigerating cycle for constant temperature/moisture apparatus
Inventor: HAYASHIDA TATSUO
IPC: F25B1/00
Filed: 1987-07-15
Abstract: PURPOSE: To execute quick cooling operation even when the temperature in a tank is high and prevent the decline of refrigerating capacity even when the temperature is low by effecting cycle switching by a solenoid valve so as to constitute a cycle using a suction cooler when the temperature in the tank is high and another cycle using no suction cooler when the temperature is low. CONSTITUTION: The refrigerating cycle is switched by means of a microcomputer by making a first electromagnetic valve 7 and a second electromagnetic valve 6 determine a high-temperature state and a low temperature state, with a boundary of +12 deg.C in a tank. When the temperature in the tank is high, a refrigerating cycle using a suction cooler 4 is started by opening the valve 6 and closing the valve 7. In this state, the operation of a refrigerating-cycle compressor 1 becomes possible, because the temperature of the suction gas of the compressor 1 drops. When the temperature in the tank is low, another refrigerating cycle using no suction cooler is started by cutting off the suction cooler by opening the valve 7 and closing the valve 6. Therefore, the deterioration of the refrigerating capacity due to the suction cooler 4 can be prevented in this refrigerating cycle.

Filed: 1988-07-15
Abstract: PURPOSE:To form thermal transfer lettering with excellent fretting resistance of an ink on an image-receiving sheet by incorporating a thermoplastic acrylic resin in an ink layer of a thermal transfer ribbon, and providing a thermoplastic resin layer on an image-receiving surface of the image-receiving sheet. CONSTITUTION:A thermoplastic acrylic resin is incorporated in an ink layer of a thermal transfer ribbon in an amount of at least 10wt.%, whereas s single or two or more kinds of thermoplastic resin layers having a softening point of 50-165 deg.C is provided on an image receiving sheet, the thickness of the thermoplastic resin layer(s) on the sheet is set to be 0.1-10mum, and the center line average roughness (Ra) in a reference length of 0.08mm according to JIS B 0601 of the surface of the thermoplastic resin layer is controlled to or below 1mum. This construction makes it possible to obtain a printed image with excellent fretting resistance. If the content of the acrylic resin is less than 10wt.%, the fretting resistance of the printed image will be unsatisfactory. If the softening point of the thermoplastic resin is below 50 deg.C, the fretting resistance is poor whereas if the softening point is above 165 deg.C, transferability of a ribbon ink will be poor.
