Title: Air vent structure of fuel tank
Inventor: UTSUNOMIYA AKIHIRO
IPC: B60K15/035
Filed: 1999-06-14
Abstract: PROBLEM TO BE SOLVED: To smoothly fill fuel in a fuel tank as the vicinal part of the tip of the air vent pipe is not clogged with bubbles by covering a cap having an orifice in a bottom part and having an opening port on the upper end. SOLUTION: A feed oil pipe 2 is connected to a side surface of a fuel tank 1, an air vent pipe 3 is connected to an upper part, and the feed oil pipe 2 and the air vent pipe 3 are united just under an oil filler port 4. The vicinal part near to the tip 3A of the air vent pipe 3 is covered with a cap 6, an orifice 7 is provided in this bottom part, and an opening port 8 is provided on the upper end. When a flow speed of fuel O flowing in the feed oil pipe 2 becomes fast, bubbles F are formed on a liquid level of the fuel O. However, these bubbles F are cut off from infiltrating into the cap 6 by the orifice 7, and since the opening port 8 is positioned on the upper end, the neighborhood of the tip 3A of the air vent pipe 3 is not blocked up by the bubbles F to be thereby brought in a state that the fuel O is filled up in the fuel tank 1.

Title: Optical recording and reproducing device
Inventor: ARAI SHINICHI
IPC: G11B7/0045
Filed: 1990-06-27
Abstract: PURPOSE:To monitor the recording state in real time during recording by providing a means for monitoring the recording state with return light of a laser beam irradiating a recording medium during the recording. CONSTITUTION:At the time of recording, a photodetector 6 is irradiated with the return light of laser power and a signal corresponding to the power of the return light is outputted. When the recording laser power becomes high level, the quantity of return light from an optical disk 1 is increased, so that output of the photodetector 6 is also raised, but the saturation of an HF amplifier 18 caused by this can be eliminated. Consequently, a signal just like the same level at the time of recording a data is obtained as an output signal (d) of the HF amplifier 18, and this signal (d) is automatically sliced by a comparator 22 to output a signal (e). The signal (e) is passed through an inverter, and its output signal is denoted as (g), which is obtained from a terminal 25 as the same signal at the time of reproducing. By this method, the signal during recording is reproduced in real time, and is monitored.

Title: Core cutter
Inventor: MORI TERUYUKI
IPC: B28D1/04
Filed: 1996-06-27
Abstract: PROBLEM TO BE SOLVED: To certainly and efficiently shape and cut a concrete structure containing many iron materials, by arranging a grinding particle mixed chip consisting of a plurality of diamond grinding particles and CBN grinding particles or cemented carbide particles to the leading end of a core cutter main body. SOLUTION: A core cutter 1 is formed by welding a plurality of grinding particle mixed chips 3 to the leading end of a core cutter main body 2 by silver solder. The core cutter 1 has the grinding particle chips 3 formed by mixing diamond grinding particles excellent in the cutting of concrete but difficult in the cutting of an iron material, and CBN grinding particles excellent in the cutting of the iron material but difficult in the cutting of concrete itself or cemented carbide particles arranged thereto.  That is, since CBN grinding particles or cemented carbide particles are insufficient in hardness as compared with diamond grinding particles, they are markedly abraded at the time of the cutting of concrete but, since those grinding particles are larger than the diamond particles at a time of the cutting of the iron material, an iron powder is not entangled with grinding particles and the reaction with carbon is hard to generate.

Abstract: PURPOSE: To eliminate a starting delay of a time ratio control directly after a switching by a method wherein an output of a comparison reference signal which decides a time ratio is started when a brake control is changed-over to a time ratio control.  
     CONSTITUTION: A detection circuit 4 outputs a switching signal e 1  when a wheel speed is less than a desired value V 1  and outputs a switching signal e 2  when the wheel speed exceeds the desired value V 2 , based on a wheel speed signal VW. A decompression signal generating circuit 6 generates a saw tooth wave signal based on the switching signal e 1  and this signal is compared with a retartdation signal from a retardation detection circuit 5A to generate a decompression signal, and further, a booster signal generating circuit 7 generates a booster signal based on the switching signal e 2  in the same way. These decompression and booster signals are entered into an oil pressure adjustment device 8 to control a damping force. Since the saw-tooth wave signal is generated based on the switching signal, the needless decompression and booster signals are not outputted.

Fading of the recording film consisting of an org. dye can prevent the progression of a fading reaction when the contact of oxygen with the recording film 1 is suppressed. The infiltration of the oxygen which is the case for inducing the fading into the optical recording medium and the contact thereof with the recording film 1 are, therefore, suppressed by using the material having the small oxygen permeation rate to constitute both the surfaces of the recording film 1 consisting of the org. dye. The light resistance is improved in this way.
