IPC: G11B27/10
Filed: 1983-05-16
Abstract: PURPOSE:To detect easily a rotation stop of a disk by constituting so that a stop of a rotation of the disk is detected basing on a vibration signal obtained from a tracking control signal forming circuit. CONSTITUTION:When a rotation of a disk 1 is stopped, an output of an error amplifier 22 is not vibrated, and a trigger pulse shown in the figure F is not generated. The stop of the disk 1 can be known by an output of a monostable multivibrator 30 at the time point t4 shown in the figure G, but a D-type flip- flop 31 is also provided, and by this Q output, the stop is detected. An input of the D-type flip-flop 31 is an output of an AND gate 33, therefore, it is in a high level before the time point t4. Subsequently, a leading edge signal of the the point t4 of the output the monostable multivibrator 30 shown in the figure G is inputted as a clock to the D-type flip-flop 31, a D input of its time point is held, and its Q output is inverted to a high level at about the time point t 4 as shown in the figure H, basing on which a stop detecting signal is obtained.

Title: Obstruction detector for vehicle
Inventor: KATAYAMA SUSUMU
IPC: G01S7/521
Filed: 1986-04-14
Abstract: PURPOSE:To prevent an ultrasonic oscillation element from being contaminated with a foreign matter and receiving intentional mischief by mounting the transmitting and receiving ultrasonic oscillation element to the inner wall of the bumper of a vehicle. CONSTITUTION:The oscillating surface 1a of an ultrasonic oscillation element 1 fixed to a bumper 5 oscillates the thin wall portion 5a thereof directly and closely attached to the surface 1a to transmit ultrasonic waves to the surface side of the bumper 5. When the transmitted ultrasonic waves are reflected from an object and returned to the side of the bumper 5, the reflected waves oscillate the oscillating surface 1a of the element 1 through the oscillation of the thin wall portion 5a. The element 1 receives the reflected waves by means of the oscillation of the oscillating surface 1a and outputs receiving signals corresponding to the reflected waves to a received wave detector via a lead wire 2 and the like. Since an obstruction detector is so constructed that the element 1 mounted to the inner wall of the bumper 5 detects the object, the element 1 can be prevented from being contaminated with a foreign matter such as mud on the surface of the element 1 and receiving intentional mischief.

Title: Production of speaker damper
Inventor: SUMIYAMA MASAHIDE
IPC: H04R31/00
Filed: 1989-04-04
Abstract: PURPOSE:To improve the linearity and to reduce the mechanical resistance by using a metallic mold divided in the damper radius direction to produce a speaker damper. CONSTITUTION:A metallic mold is divided into a top force 16 and a bottom force 17 and each of both forces is also divided for each corrugation toward the outer circumference from the center part and in the circular circumference direction of the mold. When a damper is formed with this metallic mold, a center metallic molds 4 and 5 are set to each other to clamp the inner circumference part of a base material 18 to be formed into the damper. A corrugation recessed metallic mold 6 rises up and then a corrugation projecting metallic mold 7 falls down. Thus a 1st corrugation is formed at the inner circumference part of the material 18. Then a corrugation recessed metallic mold 8 and a corrugation projecting metallic mold 9 move up and down for production of a 2nd corrugation. Hereafter the corrugations are successively produced in the same way toward the outer circumference. Thus, the force is applied evenly to any part of the damper which is produced in such a process since no excess force is applied to the damper at its molding.

Abstract: PURPOSE:To attain high speed processing by isolating electrically a back gate of a MOS transistor(TR) being a component of a differential amplifier circuit from the source and keeping a potential of the both at a prescribed relation thereby eliminating a substrate bias effect and the effect of parasitic capacitance. CONSTITUTION:A voltage shift circuit 13 is used, a gate voltage of a MOS TR M3 is shifted by a sum between a gate-source voltage of the TR M3 and a base-emitter voltage of a TR Q2 to provide an operating point to a back gate drive circuit 14 comprising the TR M4 and a TR Q3. The same TR is employed for the TRs M3, M4, Q2, Q3 and the voltage is made equal to a source voltage of the TRs M1, M2. Thus, a large parasitic capacitance CP is separated from a source being a signal path of the TRs M1, M2 to avoid the effect thereby improving a through-rate and the same potential is given to the source and the back gate at all times to prevent production of the substrate bias effect.

IPC: H01S3/08
Filed: 1988-04-08
Abstract: PURPOSE:To eliminate the angle deviation of a projecting beam by a method wherein at least two or more mirrors which constitute a laser resonator are periodically slanted so as to enable an optical axis at the misalignment to be parallel with an optical axis at the alignment. CONSTITUTION:A laser beam 8 totally reflected as being magnified by a convex total reflection mirror 2 is amplified through a laser medium 7 and then collimated to be a parallel laser beam 9 with a collimating mirror 6, and the laser beam 9 is amplified again through the medium 7 and its peripheral part is taken out as a ring-shaped laser beam 10 through a window 1 via the circumference of the total reflection mirror 2. When a mis-aligning state that an optical axis does not penetrates through the centers of the mirrors 2 and 6 is made to occur by changing the slant of the mirror 6 and the window 1 held by an elastic piece 3 through the expansion and contraction of a piezoelectric element 4, the laser oscillation stops. When an optical axis at the mis-alignment is made to be parallel with the optical axis at the alignment by slanting the mirror 6 and the window 1 at the same time, the angle of the laser beam 10 is prevented from deviating, so that the positional change of the beam 10 can be decreased even if it is transmitted through a long distance.

Title: Hysteresis circuit
Inventor: SHIBATA MANABU
IPC: H03K3/037
Filed: 1985-04-24
Abstract: PURPOSE:To obtain the sufficiently large and stable hysteresis width by shifting the level of one of both input signals applied simultaneously to the inputs of two logical circuits by means of a constant voltage element. CONSTITUTION:A level shift circuit consisting of a resistance R1, a diode D1 serving as a constant voltage element and a transistor TR Q1 is provided at the input side of two logical circuits L1 and L2 respectively. This level shift circuit shifts the signal Vin supplied to the circuit L1 to a higher level than the signal Vin supplied to the circuit L2 by an amount equal to the forward voltage Vf of the diode D1. Therefore a difference equal to the voltage Vf is produced between the apparent input threshold value Vth1 of the circuit L1 and the Vth2 of the circuit L2. Thus the sufficiently large hysteresis width is obtained and furthermore this hysteresis width is stabilized to be free from the effect of the variation of the power supply voltage.

Abstract: PROBLEM TO BE SOLVED: To provide a supporting device where the supporting state of a member to be fixed is maintained and inspected timely by predicting that, for instance, the screwing between a fixing side rod and a turn buckle is off sooner or later because the turn buckle continuously turns. SOLUTION: A connection member 40 arranged to be bridged between a fixing side and a side to be fixed can detect relative movement of a fixing side rod 310 and a rod side 320 to be fixed on a rod axis.

It is possible to know that the rods 310 and 320 are relatively separated from each other on the rod axis from the tension state of the member 40. It is consequently possible to predict that the screwing between the part 311 of the rod 310 and a 1st screwed part 331 of the buckle 330, and between the part 31 of the rod 320 and a 2nd screwed part 332 of the buckle 330 is off sooner or later.
