Abstract: PURPOSE:To ensure the stability and safety of traveling without loosing amusement property by constituting a handle in such a manner as to be longitudinally movable, moving the handle forward, when the handle is released, and also bringing a rear wheel into contact with a frictional member to arrest the rotation of the rear wheel. CONSTITUTION:When an occupant sits in a vehicle body 12 and pulls a handle 18 on this side, a front wheel 14 integrated with the handle 18 is oscillated clockwise and pressed onto the ground, and the front part of the vehicle 10 is floated by this reaction. A transmission frame 30 is also pulled forward, a rear wheel 16 is oscillated clockwise around a horizontal shaft 38 through an arm 36. Consequently, the frictional ring of the rear wheel 16 is separated from a parking frictional member 42 to release the braking force, so that the vehicle 10 can slide on an inclined surface. When the handle 18 is rotated around the vertical shaft during this traveling, the front wheel 14 is rotated in the same direction, so that the vehicle 10 can be steered. When the handle 18 is further pulled to this side, the rear wheel 16 makes contact with a braking frictional member 40, so that the vehicle 10 can be braked.

Inventor: NISHITAKE SHIGERU
IPC: E21D9/13
Filed: 1994-02-28
Abstract: PURPOSE:To display the function of muddy-water treatment equipment installed into a tunnel in the same degree as the ground, to dispense with the place of mounting on the ground and to solve the problem of noises by decompressing the pressure of high-pressure muddy water to atmospheric pressure by a spiral type decompression device. CONSTITUTION:High-pressure muddy water (q) from a shielding cutter 2 is forwarded to a spiral type decompression device 7 by a sludge withdrawal pipe 5 and a muddy-water pump 9. High-pressure muddy water (q) is introduced into a circular type spiral casing for the spiral type decompression device 7 from an inlet nozzle connected in the tangential direction, decompressed to atmospheric pressure while forming a vortex, and sent out to a muddy- water treatment device 6 at the rear of the shielding cutter 2 in the axial direction from an outlet nozzle at the center of the spiral casing. The change in facing pressure and a flow rate due to the variation of the conditions of excavation are accomodated by the introduction of high-pressure water Q from an adjusting nozzle. Since the muddy-water treatment device 6 displays sufficient capacity even when ground installation type muddy-water treatment equipment is used because high-pressure muddy water is decompressed to atmospheric pressure and fed, soil and sand 13 separated from water may be discharged to a hopper 14 on the ground by a lift conveyor 12.

CONSTITUTION:Mold main body 1 is formed by electroforming, and a number of through-holes 2 provided through the mold main body 1 are constituted of micro non-electrodeposit sections generated in the initial stage of electroforming and grown in the thickness direction at the time of electroforming, and the diameters of said through-holes are increased gradually from the surface of the mold main body 1 toward the back face. Desirably the maximum diameter of said through-holes 2 on the surface side of the mold main body 1 should be 0.1-0.5 mm, and the number of through-holes 2 should be 5-10000 per 10 cm<2> area of the mold main body 1 from the viewpoint of vacuum suction force. As the through-holes 2 are passed through by growing micro non-electrodeposit sections, air flow resistance in vacuum suction is low to carry out vacuum section more easily. Also, the through-holes 2 are seldom clogged and the inside of the through-holes 2 can be easily cleaned.

Title: Television camera
Inventor: IKEDA KATSUYUKI
IPC: H04N5/232
Filed: 1981-03-02
Abstract: PURPOSE:To realize a lightweight, small-sized TV camera which uses a liquid crystal display body for its viewfinder, by eliminating the disadvantages that the cathode-ray tube of the liquid crystal display body has different display characteristics and a display dynamic range is narrow. CONSTITUTION:A luminance signal Y obtained by a gamma correcting circuit 523 is inputted to a gamma correcting circuit 515 which corrects the nonlinearity of liquid crystal and after correction, the resulting signal is led to a liquid crystal display body through a buffer amplifier 516. Display brightness on a cathode-ray tube is proportional to a driving voltage raised to 2.2th power, and therefore gamma=1/2.2 compressed at a high level side is used for a signal gamma-1. A pattern generating circuit 512 generates this signal gamma=1/2.2. Using this signal adjusts the circuit 515 correctly to the characteristics of the liquid crystal display body.

Abstract: PURPOSE:To enable accurate calibration free from changes in light outputs of a light source by a method wherein two lights divided with a halfmirror are allowed to pass and break simultaneously with a shutter and the luminous flux passed is received with light power meters, the one on the side of a reference device and the other on the side of a device to be inspected. CONSTITUTION:The luminous flux of a laser light radiated from a light source 1 is attenuated down to a certain level with a halfmirror 7 and further, in two directions with a halfmirror 2.

The simultaneous opening or closing of the shutters 3 and 4 enables the measurement of the power of the laser light at the simultaneous timing with the reference device 5 and the device 6 to be inspected. In this case, the measurement at the same time allows the removal of instability of the light source free from changes in the light power of the light source 1.

Abstract: PURPOSE:To prove simply and rapidly the presence and absence of the fluidizing agent at a working site by taking up the supernatant liquid by diluting a fluidized concrete sample by water, making the supernatant liquid acidic, then shaking violently the supernatant liquid by adding or without adding a specified bubble retaining agent, and then measuring the continuance time of the bubbles on the liquid surface. CONSTITUTION:A small quantity of fluidized concrete sample is picked up, diluted to 5-20 times and mixed, the supernatant liquid after the sedimentation of the solid part is taken up, or an acid such as sulfuric acid is added to the filtrate filtered by a filter paper or cotton, etc. to make it acidic and the color of the solution is vanished to make the solution easy to observe. The one part of the solution is fed into a test tube, shaken violently and allowed to stand. If the fluidizing agent consisting essentially of lignin sulfonic acid salt is present, the bubbles are continued for >=5min, but if the agent is not present the bubbles are little and disappear suddently. If an organic solvent lighter than water and not mixed with water such as toluence, machine oil and powder such as talc are added as a bubble retaining agent to the supernatant liquid and the filtrate and bubbled similarly, the bubbles are continued for >=30min in case of the presence of the fluidizing agent, and disappear suddenly in case of the absence. The fluidizing agent can be determined semiquantiatively by the disappearing time of the bubbles.
