Title: Telemeter system
Inventor: SAITO ATSUSHI
IPC: H04M11/00
Filed: 1988-08-17
Abstract: PURPOSE:To eliminate need for adjustment when a telemeter system is installed to the customer side and to simplify a job by setting a signal level received at the information collection station side to a proper value for each customer. CONSTITUTION:When a signal from the customer side to the information collection station is received by a transmission reception means 1, a comparison means 2 compares the signal level with a prescribed level and if there is any difference, a correction signal generating means 3 sends a correction signal corresponding to the difference to the customer side via the transmission reception means 1. The adjustment means 6 adjusts the signal level corresponding to the correction signal at the customer side. As a result, the level of the signal sent from the customer side to the information collection station is set to an optimum value automatically, then the adjustment by a skilled personnel is not required and the installation time is reduced.

Title: Magnet runner structure of thin curtain rail
Inventor: SUGIYAMA TERUYUKI
IPC: A47H23/01
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To provide a magnet runner structure of thin curtain rail in which handling property, storing property, and working property can be improved, and the cost can be also reduced by forming lateral magnet runners installed to the tops of lateral curtains to hold the curtains in closed state from one kind of magnet runner. SOLUTION: Lateral magnet runners 1a, 1b suspended from a thin curtain rail 5 through rollers 6 are formed by vertically reversing and inserting the same magnet holder 3 from lateral sides of a runner body 2. The claw part of the magnet holder 2 is engaged with the protruding part of the plate part 7 of the runner body 2, whereby the runner body 2 and the magnet holder 3 are mutually fixed and held. Lateral curtains are held in the closed state by the attraction of magnets 4, 4, arranged opposite to each other.

Title: Semiconductor device and its manufacture
Inventor: WATANABE KATSUMI
IPC: H01L21/60
Filed: 1995-07-19
Abstract: PROBLEM TO BE SOLVED: To enable a semiconductor device to be lessened in thickness and wiring resistance between a semiconductor chip and a sub-circuit board, wherein the semiconductor device is equipped with a sub-circuit board so as to substantially enhance the bumps of the semiconductor chip in size and arrangement pitch. SOLUTION: Gold bumps 46 formed under a connection pad 43 of a semiconductor chip 41 are directly bonded to a gold plating layer 33 formed on a first connection pad 22 of a sub-circuit board 21, so that a semiconductor device is lessened in wiring resistance. The gold bumps 46 are comparatively high and set as high as 10 to 80μm, preferably 20 to 40μm after they are bonded. The reason why the bumps 40 are set comparatively high is that a resin sealing material 51 is easily embedded between the upside of the sub-circuit board 21 and the underside of the semiconductor chip 41 caused by a capillary phenomenon.  In this case, though the gold bumps 46 are set comparatively high, a gap between the upside of the sub-circuit board 21 and the underside of the semiconductor chip 41 is stopped up with resin sealing material 51, so that a semiconductor device of this constitution can be lessened in thickness.

Abstract: PURPOSE:To stabilize a developed image by making the magnetic force of a carrying magnetic pole stronger than a regulating magnetic pole, exerting the influence of the carrying magnetic pole, on magnetic grains in a container, and stabilizing the circulation of carrier grains in the container. CONSTITUTION:In this side of a blade 24, carrier grains 27 being in the vicinity of the surface are attracted to the surface of a sleeve 22 by a magnetic pole 23w, rotated, and also, pass through the lower end of the blade 24 and go out to the outside of a container 21, and toner grains 28 to which the grains 27 are stuck to the surface are carried out. A part of the electrified toner goes out to the outside of the container in a state that it is stuck to the sleeve surface as it is, and the blade 24 regulates the quantity of a developer to be applied to the surface. In a developing part, an electric field is applied alternately between a drum 1 and the sleeve 22 and a latent image is developed. In such a state, at the time of holding the carrier grains on the sleeve 22 by the magnetic pole 23a and 23d, when the magnetic force of a carrying electrode 23d is made stronger than the control magnetic pole 23a, magnetic grains in a container 24 circulate stably and a toner/carrier ratio is stabilized, therefore, a developed image is stabilized.
