Patent JP-H02168728-A (JP)
Title: Pwm type d/a converter
Inventor: TOYOMAKI KAZUYA
IPC: H03M1/82
Filed: 1989-07-24
Abstract: PURPOSE:To decrease the frequencies of a necessary clock signal without altering the cycle and resolution of an input signal by adding the output signal of a first PWM converter, whose pulse width is determined with an odd-number input signal value and an even-number input signal value to be next inputted, to the output signal of a second PWM converter, whose pulse width is determined with the even-number input signal value and the odd-number input signal value to be next inputted. CONSTITUTION:As soon as the digital input signal impressed to an input terminal 7 is D/A-converted into a PWM signal A by a first PWM converter 1, the input signal is D/A-converted into a PWM signal B by a second PWM converter 2. These PWM signals are added by an analog adder 5, and then outputted from an output terminal 8. After constant cycles have passed, by the even-number input signal value to be next inputted, the PWM signal A is set so as to fall from an H level to an L level, and the larger the input signal value is, the more a timing position is backward extended. Further the PWM signal B is set so as to rise from the L level to the H level, and the larger the even-number input signal value is, the more the timing position is shortened. Thus, when the cycle of the input signal and the frequencies of the clock signal are the same as conventional ones, the resolution can be increased to (a double value + 1).

Title: Double link type suspension device
Inventor: MURAKAMI TAKUYA
IPC: B60G3/20
Filed: 1986-08-14
Abstract: PURPOSE:To increase the width of an engine room and the like in a double wishbone type suspension device with a buffer by providing an axial knuckle along a king pin axis through the connecting part with an extending member and that between the knuckle and a lower arm, and including the connecting part with an upper arm toward the crossing direction with a wheel. CONSTITUTION:A knuckle 3, a wheel 1, and an axle 18 are rotated about a king pin axis 11 by steering force inputted to the knuckle 3 at the time of rotation. However, since the knuckle 3 is able to rotate freely because of a bush 10, an extending member 4 does not rotate. Therefore if the wheel 1 moves up and down, only vertical motion is produced at the extending member 4, and relative motion to upper arm 5 only includes oscillation. Thus a ball joint need not be used for connecting the extending member 4 and the upper arm 5, and only a rubber bush 12 is needed instead. Therefore the size of a joint is smaller and the height of a wheel house can be shorter, thereby the width of an engine room can be increased relating above.

Title: Torque limiter of planetary gear
Inventor: SHIBATA TORU
IPC: F16H1/28
Filed: 1990-07-21
Abstract: PURPOSE:To secure constant fixed torque, prevent its fluctuation and enable compactness by meshing a rotatable fixing gear with a gear on the periphery of an internal sun gear to fix an internal sun gear, and enabling the rotation of the internal sun gear by the elastic deformation of the fixing gear. CONSTITUTION:In spite of an internal sun gear 16 trying to perform its rotation in company with a gear 18, the rotation of the internal sun gear 16 is impeded by the variable diameter of a hexagonal gear 12 and also by the movement of a mesh point from the small diameter part of the hexagonal gear 12 to its large diameter part, so that the internal sun gear 16 is held in the fixed state. The torque of a motor 21 decelerated by a planetary gear 14 is thereby transmitted to an output shaft 22 so as to rotate this output shaft 22 together with a driven body 24. However, when larger torque than the fixed torque is applied to the driven body 24 to generate the flexural deformation of the hexagonal gear 12 and the bending deformation of a shaft 12a, the fixed state of the internal sun gear 16 is released and becomes rotatable. The output shaft 22 is thereby rotated together with the internal sun gear 16, and the driven body 24 races in company with the output shaft and the internal sun gear 16.

According to this classification, the acceptable discs are determined at this stage without requiring a glide test and the certification. The accepted magnetic discs are obtained at the rate of about more than 30%, meaning that the proportion of the discs to be inspected is 70% or less, thereby improving the inspection efficiency.  As to the magnetic discs of the second category, the data and identification information of the positions of the defects are outputted and can be utilized for the subsequent inspection process, thereby further improving the through put of the inspection.

Title: Print erasure head of reversible magnetic recording medium
Inventor: YASUKAWA KAORU
IPC: G09F9/37
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To provide a print erasure head of a reversible magnetic recording medium allowing a structure to be simplified and reduced in size, and an inexpensive cost. SOLUTION: A print erasure head is basically constituted of a cylindrical magnetic body 8 (for example, pure iron) and a coil 7 as a magnetic field and heat generation means. The coil 7 is connected with a current and frequency control device 16 (electricity transmission means) via conductors extending therefrom. A current signal is supplied from this device 16 to the coil 7 to produce a magnetic field. Eddy current is caused to flow due to the magnetic field. This eddy current causes to generate heat in the magnetic body 8. Due to this heat generated in the magnetic body 8, a dispersion medium 4 is reduced in viscosity. On the other hand, since the magnetic body 8 is magnetized by a same signal made to flow through the coil 7, a strong magnetic field is generated in the neighborhood of the magnetic body.  Magnetic particles 3 in the dispersion medium 4 reduced in the viscosity are applied with a force by the magnetic field generated in the neighborhood of the magnetic body 8, and are moved on a surface side of the medium to display image information.
