Title: Transmitter in signal transmission equipment
Inventor: TSURUI SHOZO
IPC: H04B5/00
Filed: 1986-03-14
Abstract: PURPOSE:To attain the information transmission at a nearby distance with simple constitution by providing a resonance circuit including a switching element switching the resonance state and a coil subject to electromagnetic induction coupling with a coil of an oscillation circuit at the reception side to a transmission equipment. CONSTITUTION:When a coil L2 of a resonance circuit 2 of a transmitter 20 is in mutual induction coupling close to a coil L1 of an oscillation circuit 1 of a receiver 10, since the effective inductance of the oscillation coil is changed, a frequency deviation of f+ or -DELTAF is fed to the oscillation frequency. The frequency deviation differs from on/off of a switching element 21. Thus, based on the data stored in a memory 23, when the switching element 21 is turned on/off, an oscillation output Sf corresponding to the data is obtained. In demodulating the output Sf by an FM demodulation circuit 13, a modulation signal R is obtained and used as a reception data.

Abstract: PURPOSE:To prevent a rotating central shaft from decentering and inclining even when the temperature of one's own magnetic disk device and the circumference are changed by constituting the parts abutting on the upper/lower and radius directions of a bearing of a material having the approximately same linear expansion coefficient as the bearing. CONSTITUTION:For bearings 7 and 8, a linear expansion coefficient is 12.5X10<-6>/ deg.C in a bearing steel, and the linear expansion coefficient (for example, a SUS 440C is 10.1X10<-6>/ deg.C) of the parts (interval pipe 10', shaft 4 and housing 6') of the circumference is approximately the same (comes to be a little smaller than the bearing, and when the diameter of the bearing is smaller, it does not matter). Thus, the thermal expansion of the radius direction and the thickness direction of the bearings 7 and 8 and the ambient parts can be approximately equal, the vibration and turning of a spindle at the time of high temperature which is generated by the thermal expansion difference can be suppressed, and the decrease of the off-track is attained.

Title: Window device for automobile
Inventor: KANAMARU HIROSHI
IPC: B60J3/04
Filed: 1988-03-09
Abstract: PURPOSE:To always easily obtain a good field of view automatically changing transmittancy of a window use transparent plate in accordance with intensity of the rays of the sun by forming the window use transparent plate of an automobile with a dimming transparent plate containing a photochromic substance. CONSTITUTION:A window use transparent plate 2 is mounted through a weather strip to the front surface of a cabin 1 in an automobile, for instance, large truck. Here the window use transparent plate 2 contains, for instance, in its upper half part a photochromic substance, thus being given a function as the dimming transparent plate. When the sunlight is irradiated, the photochromic substance, absorbing the sunlight, is discolored transferring to a semi-stable condition of different absorptivity of light, thus transmittancy of light is decreased. On the contrary, when no sunlight is irradiated, the dimming transparent plate is returned to the original color, for instance, colorless. Thus automatically changing the transmittancy of the window use transparent plate 2 in accordance with intensity of the sunlight, a good field of view is always easily obtained.
