Title: Aging apparatus of capacitor
Inventor: KOBAYASHI KAZUO
IPC: H01G13/00
Filed: 1988-12-05
Abstract: PURPOSE:To reduce a power consumption and to easily control a ripple current value flowing to a capacitor by installing a boosting circuit which is connected between both terminals of the capacitor, executes a switching operation, boosts a voltage between the terminals and feeds it back to a direct-current power supply. CONSTITUTION:A signal of a pulse width corresponding to an output signal level of an error amplification circuit 18 is applied to a base of a transistor 15 from a comparison circuit 20 at a cycle corresponding to a cycle of a triangular-wave signal; the transistor 15 executes a switching operation. A ripple current value can be set arbitrarily by setting a reference voltage of a reference-voltage source 19 in a variable manner. A ripple current of a capacitor 11 is regenerated by a boosting circuit and is fed back to a direct-current power supply 12; accordingly, a power consumption can be reduced.

Title: On-vehicle communication equipment and two-way road side beacon communication system
Inventor: IWAI TORU
IPC: H04B7/26
Filed: 1991-11-21
Abstract: PURPOSE:To attain smooth communication by limiting the number of vehicles making transmission from the vehicles to a road side beacon to some degree in the case of 2-way communication between the road side beacon and the vehicles. CONSTITUTION:Only when a reception level discriminator 32 detects it that a level of a reception radio wave from a road side beacon is a prescribed reference value or over, the transmission of a radio wave from an on-vehicle communication equipment 1 is attained and when less than the reference value, the transmission of the radio wave from the on-vehicle communication equipment 1 is inhibited. Thus, the radio wave from the vehicle at a distance close to the road side beacon is sent and production of crosstalk due to transmission of radio waves from lots of vehicles is reduced.

IPC: G01N23/20
Filed: 1993-11-15
Abstract: PURPOSE:To measure a thin-film crystal structure by an X-ray diffraction method by constituting a substance to be measured so that its width will be smaller than the particular diameter of a phase transition substance that has bean changed in phase and it is also partitioned with amorphous films. CONSTITUTION:By patterning a substance to be measured in a manner that its width will by smaller than the particular diameter (a) of a substance after phase transition, the crystal growth during phase transition can be limited in one direction, and as the result, the crystal particular diameter after phase transition will show a bamboo (node of bamboo) structure. On the other hand, if the substance to be measured is patterned larger in width than the particular diameter (d) of phase-changed substance, the crystal growth during phase change will become non-anisotropic, and as the result, the crystal particular structure after phase transition becomes a polycrystal construction. Thus, by limiting the crystal growth direction, the crystalization after phase transition can be added with greater anisotropic property, crystal particles with similar crystal direction is increased because of improved selective orientation, and the diffraction X-ray intensity may be increased.
