Title: Intake device of engine with mechanical type supercharger
Inventor: NAKAGAWA YOSHIHIRO
IPC: F02B33/00
Filed: 1990-11-29
Abstract: PURPOSE:To prevent shock caused by rapid increase in supercharging pressure by providing a pressure chamber which introduces pressure on the downstream side of a supercharger, and another pressure chamber which introduces pressure higher than the atmospheric pressure but lower than the pressure on downstream side of the supercharger at the time of supercharging, while holding a diaphragm between those chambers. CONSTITUTION:There is provided an opening/closing valve 20 which opens a bypass passage 10 which communicates the upstream side to the downstream side of a supercharger 3 in a non-supercharging range and closes the same valve 10 in a supercharging range. The valve body 21 of the opening/closing valve 20 is arranged in the bypass passage 10 so as to force the pressures on the upper and lower stream sides of the supercharger 3 to act on the observe and reverse of the valve body 21 respectively. One side of a diaphragm 23 connected to the valve body 21 is provided a first pressure chamber 24, and pressure on the downstream side of the supercharger 3 is introduced therein. The first pressure chamber and the second pressure chamber 25 opposite thereto are provided while holding the diaphragm 23 between them, and the pressure lower than the pressure on the downstream side of the supercharger 3, but higher than the atmospheric pressure is introduced therein. Consequently, since rapid closing operation of the opening/closing valve 20 can be prevented by the pressure acting on the second pressure chamber 25, torque shock caused by rapid increases in the supercharging pressure can be prevented.

Title: Code image recording method
Inventor: YOSHIOKA KENJI
IPC: G06K19/06
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To suppress the reading mistakes of dots due to their thickening by modulating the data which are recorded so as to limit the number of dots which are continuous in the horizontal scanning direction orthogonal to the relative moving direction to a recording medium. SOLUTION: A code image 1 has a modulation area 2 and a non-modulation area 3. Plural dots 4 are arrayed in the area 2 according to the data to be recorded. The area 3 includes a standard index 5 which is used for reading the dots 4 contained in the image 1 and a header 6 which can be optically read and records the restoration parameter data necessary for restoring the image 1 into the original data. The data are modulated to limit the number of dots 4 to be recorded in the area 2 and continuous in the horizontal scanning direction of a printer head. In this example, the number of dots 4 continuous to the horizontal scanning direction of the printer head is limited to two pieces at most via the data modulation processing.

Title: Effective rescaling method for hot rolling
Inventor: WATANABE KUNIAKI
IPC: B21B15/00
Filed: 1999-11-29
Abstract: PROBLEM TO BE SOLVED: To provide an effective descaling method for a billet preventing the formation of red scales. SOLUTION: In the descaling method for a billet extracted from a furnace before a hot rolling, the billet extracted from the furnace is pressed in the lateral direction by a sizing press to crack the scales forming on the product surface and float the cracked scales from the surface, and then descaled by very high-pressure water. And before pressing the billet extracted from the furnace by the sizing press in the lateral direction, the billet is descaled on all sides by spraying high-pressure water. After the billet is pressed in the width direction by the sizing press, descaling is performed by low-pressure water, then descaling is performed by very high pressure water. Thus, the effective descaling method is carried out by combining the processes described above.

Abstract: PURPOSE:To prevent the generation of crosstalk at the time of adjustment, and in addition, to simplify the adjustment, and to improve an image height characteristic by arranging the adjusting fulcrum of skew adjustment and a first adjusting screw to adjust a tangential direction and a second adjusting screw to adjust a radial direction in specified positional relation. CONSTITUTION:At the time of the skew adjustment, at first, the adjustment of the radial direction is executed by rotating the first adjusting screw 22, and moving the fitting position of a base part 2 upward and downward to a base stand part 3. Thus, the base part 2 is rotated on the base stand part 3 around the center of the base stand side principal point H1 of an objective lens 1 to a direction A shown by an arrow mark. After that, the adjustment of the tangential direction is executed. At that time, the second adjusting screw 23 is rotated, and the fitting position of the base part 2 is moved upward and downward to the base stand part 3. Thus, the base part 2 is rotated on the base stand part 3 to the direction A shown by the arrow mark, and the objective lens 1 is inclined against an optical axis 51 by a prescribed angle. As for the adjustment of the tangential direction, since the adjustment fulcrum 21 and the adjusting screws 22, 23 are arranged at the specified positions, it can be executed without causing the crosstalk between this adjustment and the radial adjustment completed before.
