IPC: B61L3/02
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To make a passing position so as to be recognizable by a reflected sound of one's own travel vehicle in case of a subway or the like. SOLUTION: A passing spot recognizing structure consisting of a partition wall 20a provided with transparent holes 30 and 40 different each in size along the tracking direction is installed between both up and down tracks 10 in a subway cavern road.

Title: Strip-cutting method and device
Inventor: HARA TSUTOMU
IPC: B23D25/12
Filed: 1977-11-25
Abstract: PURPOSE: To line connecting the axis of an upper drum and a lower drum respectively fitted with an upper blade and a lower blade, which are supported by a bearing, is slanted with respect to the angle of advance. Under this condition, a strip is cut in such a manner that the cutting is done most suitable to the thickness of the strip.  
     CONSTITUTION: When the thickness of the strip is changed from t 1  to t 2 , worm wheel 9 is rotated by the slanting operation driving unit via Screw worm 10. Screw rod descends due to the rotation of this worm wheel 9, and housing 4 inclines forward about pin 3 as center. As a result, the inclination of the line connecting the axis of drums 14 and 15 is changed. Accompanying this change, the blade gaps are automatically changed in accordance with the thickness to be cut. Conssequently, since the ratios of blade gaps to be set, G 1 , G 2  to plate thicknesses t 1 , t 2  are constant, it is not necessary to consider, for the range of feasible cutting, the blade gasps corresponding to the different thicknesses, and as a result, it is not necessary to change the setting of blade gaps, and cutting is done with most suitable gaps at all times.

Filed: 1982-08-14
Abstract: PURPOSE:To obtain constant braking deceleration with the same pedal treading force by providing a throttling means which controls fluid for driving a power booster and controlling degree of throttling for the throttling means according to the car weight. CONSTITUTION:Car weight is detected through publicity known weight detection means and the highest oil pressure required for generation of the largest braking force appropriate to said weight is obtained from characteristic data prepared in advance. A motor 23 of a pressure setting part 16 is driven for control on the basis of the highest oil pressure thus obtained. By driving control of the motor 23, the position of a piston 11c of a pressure control part 11 is controlled through an arm 20, that is, the piston 11c is displaced leftward as the car weight is increased. When the piston 11c is displaced leftward, since the oil flow from an oil suppy pipe 13 to a return pipe 14 is throttled, the pressure in a chamber A is increased. With this increase, the pressure in chambers (b), (c) of a booster 6 is increased.

Title: Discriminating method of burr direction of press punched article
Inventor: SAWADA SHIYOUHEI
IPC: B24B49/12
Filed: 1984-07-10
Abstract: PURPOSE:To discriminate a burr direction by irradiating an edge part of the press punched article and detecting the intensity distribution of reflected light through an image sensor. CONSTITUTION:A projector 12 and the image sensor 13 are arranged at specific position above the press punched article P to constitute a burr direction discriminating machine. Then, the edge part of the punched article P is irradiated with light by the projection 12 and the intensity of reflected light from the edge part by the sensor 13. If there is a burr part (a) on the reverse of the punched article P, the light illuminates a roll-over part on the top and the sensor 13 detects the peak of the intensity of reflected light from the roll-over part (b). When there is the buur on the top, the intensity of the reflected light from the edge part has no peak and is almost smooth. Thus, it is decided which side of the top and reverse parts the burr part is formed from whether the reflected light intensity has a peak or not.

Abstract: PROBLEM TO BE SOLVED: To disable a limiter circuit of word line voltage with a low voltage/ low power consumption mode by turning on or off a second transistor conforming to a mode indicated by a mode signal stored in a register when a cell enable-signal is inputted. SOLUTION: Accessing to a memory cell, a cell enable-signal CE is made a high level. Then, when a mode signal is high level too, an output of an AND gate G1 is made high level. Therefore, a transistor Q2 is turned on, voltage of a word line WL is clamped to a value decided by break voltage of a zenar diode Z1. Thereby, data stored in a circuit cell is protected. On the other hand, when a mode signal is a low level, an output of the AND gate G1 is held at a low level. Therefore, the transistor Q2 is turned off and power consumption is reduced.
