Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of hydraulic pressure locking, by intermittently opening and closing a normally-closed solenoid valve to be controllable in braking force distribution control of a control unit. SOLUTION: A normally-closed solenoid valve 32A is disposed between release ports 34 of hydraulic pressure control valves 19FL, 19RR, each of which corresponds to a left front wheel brake BFL and a right rear wheel brake BRR respectively, and a reservoir 7. A normally-closed solenoid valve 23B is disposed between release ports 34 of hydraulic pressure control valves 19FR, 19RL, each of which corresponds to a right front wheel brake BFR and a left rear wheel brake BRL respectively, and the reservoir 7. When the normally-closed solenoid valves 23A, 23B are demagnetized and closed in a non-controlled state of brake pressure of vehicle wheel brakes BFL, BRR, BFR, BRL, that is, in a non-operating state of hydraulic pressure control valves 19FL, 19RR, 19FR, 19RL, the release ports 34 and the reservoir 7 are shut off from each other.  Thereby, hydraulic pressure locking is prevented from occurring.

Title: Manufacture of junction type semiconductor device
Inventor: TAKAHASHI JUNZO
IPC: H01L21/338
Filed: 1989-09-26
Abstract: PURPOSE:To achieve impurity distribution characteristics of steep stepwise junction by a method wherein, after implanting silicon ions, the heat treatment for activation is eliminated but after implanting magnesium or zinc ions in the specified region of an n type region, the heat treatment for activation is performed. CONSTITUTION:Silicon ion is implanted in a part 3 to be an n type region on one main surface of a semiconductor substrate 1 comprising GaAs not to be heat-treated for the activation of the silicon ions. Next, after implanting magnesium or zinc ions in the specified region of the n type region, the heat treatment for the activation of the ions implanted in the semiconductor substrate 1 is performed. Accordingly, the probability of the implanted magnesium or zinc ions to occupy the Ga site in GaAs single crystal is increased thereby enabling any abnormal diffusion to be avoided. Through these procedures, the impurity distribution characteristics of steep p/n junction can be displayed.

Title: Signal reproducing device using rotary head
Inventor: MIZUGUCHI NOBUAKI
IPC: G11B5/027
Filed: 1983-12-28
Abstract: PURPOSE:To obtain a signal reproducing device using rotary heads which can reduce the noise of joints of signals, by setting gains of a pair of amplifiers so that output amplitudes of these amplifiers are sufficiently larger than a DC variation generated in a switching circuit. CONSTITUTION:Gains of switch amplifiers 10 and 11 are so set that their output amplitudes are sufficiently larger than the level of the DC variation generated in a switching circuit 5. Therefore, the output of the switching circuit 5 is about 1.5Vp-p as shown by a figure (e), and the DC variation in a switching part is not distinct. Consequently, a waveform obtained by allowing the output of the switching circuit 5 to pass bandpass filters 6 and 7 has less ringing as shown by a figure (f), and the discontinuous part of signals is reduced to about 2.5musec of a third of a conventional case. Since gains of amplifiers are set to sufficient values, namely, about 95dB s that their outputs before switching have amplitudes larger than the level of the DC variation in the switching circuit 5, influences of the DC variation in joints of signals after switching are reduced sufficiently, and the discontinuous part of signals is shortened.

IPC: G03C1/42
Filed: 1986-10-20
Abstract: PURPOSE:To improve the stability of a processing liquid with age at the time of using a wash-off photosensitive material by subjecting said material to a developing process with the processing liquid having 7-11pH in the presence of a metal compd. hardly soluble in water and a compd. which can make complex forming reaction with the metal ions constituting said metal compd. hardly soluble in water and the water as a medium. CONSTITUTION:The metal compd. hardly soluble in water and the compd. which can make complex forming reaction with the metal ions constituting the hardly soluble metal compd. and the water as the medium are made to exist and the pH of the liquid is adjusted to 7-11 at the time of processing the photographic sensitive material having at least silver halide and tanning developing agent on a base. More specifically, the pH of the silver halide emulsion layer is increased by the reaction between the two compds. and the pH in this case is increased to 12-14. The decrease of the pH of the processing liquid prior to the processing to a relatively low level is thus permitted and the stability with age is improved.

Title: Screwing steel pipe pile
Inventor: OTSUKI MITSUGI
IPC: E02D5/72
Filed: 1999-09-03
Abstract: PROBLEM TO BE SOLVED: To lessen the insertion resistance of a steel pipe pile by fixing a spiral wing over substantially one winding on the lower end of a steel pipe making the body of the pile, hanging a leading cylinder fixed on the inner periphery of the spiral wing and projected downward thereof, and projecting a plurailty of window holes and excavation plates on the peripheral wall of the leading cylinder. SOLUTION: When the steel pipe pile is pushed into ground while rotating it, the excavation plate 9 of the leading cylinder 7 excavates the ground. A part of soil and sand is made into flow to the leading cylinder 7 from the window hole 8, and the other part of soil and sand is moved to the lower face of an inner wing part 5b along the conical face of the leading cylinder 7. Next, the spiral wing 5 is cut into the outside ground of the leading cylinder 7, and screwed by the reaction force of the ground acting on the upper face of the spiral wing 5 to promote insertion. Soil and sand entering a gap 6b is consolidated on the peripheral ground while sliding on the upper face of the wing of spiral inclination. Lower side soil and sand and soil and sand excavated by the excavation plate 9 are made to flow in to be pumped into the steel pipe 1.  Thus, the pile can be inserted and promoted only by rotating it by slight push pressure force, and can be buried without removing soil.
