Abstract: PURPOSE:To generate a pressure required for gap formation by the difference of thermal expansion between a jig and a head block when both of them are processed by heating, by using materials having a thermal expansion coefficient lower than that of the head block as materials of the jig. CONSTITUTION:With respect to materials of individual parts, a jig body 9 and a retaining screw 10 consist of alumina ceramics, and a retaining plate 8 consists of potassium titanate ceramics, barium titanate ceramics, a forsterite ceramics, or the like, and head blocks 11 and 11 consist of alloy magnetic materials like a 'Sendust(R)'.

Title: Antenna system and portable radio equipment
Inventor: SATO NOBUO
IPC: H04B1/38
Filed: 1995-02-09
Abstract: PURPOSE: To improve the work performance by projecting a part equivalent to a feeding point on a short-circuit conductor from an antenna side face so as to attain soldering in a short time in the antenna system having the feeding point on the short-circuit conductor. CONSTITUTION: A plane antenna 10 has a feeding section 12 on a short-circuit conductor 11 and the feeding section 12 is formed to be a rectangle and it is projected from an antenna side face (that is, side face of a dielectric material 3). When a feeder is connected by soldering, a wire of the feeder is directly soldered to the feeding section 12 projected from the antenna side face. In this case, since the feeding section 12 is projected from the antenna side face, heat caused by heating the feeding section 12 by a soldering iron or the like is hardly dissipated from the feeding section 12, resulting that solder is easily molten and soldering is conducted in a short time. Thus, the reduction in the conductor soldering strength is suppressed and exfoliation of the conductor of the feeding section 12 is prevented and the feeder soldering is conducted efficiently.

Abstract: PURPOSE:To decrease the time needed for the initialization of a magneto-optical disk to be half and to improve signal quality by providing an optical head which initializes a groove part and an optical head to initialize a land part. CONSTITUTION:When a magneto-optical disk 1 is irradiated with a light beam, simultaneously, a magnetic field is given by magnets 3 and 5. A part irradiated with the light beam of the disk 1 is heated and magnetizing inversion is generated in the magnetic field of the magnets 3 and 5. Then, magnetic field directions are aligned. Thus, an optical head 2 and the magnet 3 initialize a channel part 10 of the disk 1 by a converging light 12 and an optical head 4 and the magnet 5 initialize a land part 11 of the disk 1 by a converging light beam 13 simultaneously. Thus, in comparison with the case of the initialization by one optical head, the time to be needed for the initialization can be decreased to be half. Then, in comparison with the initialization of either one of the channel part 10 or land part 11, the signal quality is improved.

Abstract: PURPOSE:To reduce inter-wavelength crosstalk and to shorten coupling length by composing one cycle of a peak part which is a high-refractive-index area of a grating and a bottom part which is a low-refractive-index area, and varying their ratio and length over a coupling area. CONSTITUTION:The grating 8 is formed in the area where propagation modes generated in 1st and 2nd waveguides 4 and 6 are coupled. Then the grating 8 has one cycle composed of the peak part as the high-refractive-index area and the bottom part as the low-refractive-index area, the ratio of the peak part and bottom part to one cycle is distributed in a tapered shape over the coupling area, and the length of one cycle is distributed in a tapered shape over the coupling area. Desired wavelength light is demultiplexed with excellent filter characteristics, and even when the grating depth for shortening the coupling length is increased, the desired wavelength light can be demultiplexed without deteriorating the filter characteristics. Consequently, the inter-wavelength crosstalk is reduced and the coupling length comes to short.

Abstract: PURPOSE: To provide a vehicle air conditioner capable of accurately judging the pollution level of outside air by exhausting the inside of a duct prior to the judgment of the outside air pollution level. CONSTITUTION: A gas sensor signal processing circuit 30 in which a signal of a gas sensor 29 arranged in a duct is read determines the suction port mode according to the specified control program.

After switching to the inside air mode, the outside air mode is set. The pollution level of the outside air is judged after the specified waiting time passes after the outside air mode is set. That is, the pollution level of the outside air is judged after the inside of the duct is purged (cleaned) by rotating a fan 2b of a blower unit 2 in the outside air mode.
