Title: Semiconductor substrate
Inventor: HASHIGUCHI TOSHIYA
IPC: H01L21/68
Filed: 1992-01-09
Abstract: PURPOSE:To prevent a foreign matter from affecting a following process for bad even if it is produced by rubbing between a substrate contact part of a substrate carrier device and a semiconductor substrate when the semiconductor substrate is carried by a substrate carrier device by providing a recessed part to a rear of the semiconductor substrate. CONSTITUTION:Both sides of a semiconductor substrate 10 are finished flat. A rear 12 is provided with disc-like recessed parts 14 on the same circumference, desirably at specified three positions to an orientation flat 18 of the semiconductor substrate 10. Thereby, even if the semiconductor substrate 10 and the substrate carrier device are rubbed and a foreign matter is produced, the foreign matter gathers in a recessed part 14 and does not attach to a front or a rear of the semiconductor substrate. Therefore, a foreign matter does not affect smoothness of the semiconductor device for bad even if it is mounted on an exposure device and a good pattern can be formed in the semiconductor device.

Title: Film circuit
Inventor: SATO KAZUHIRO
IPC: H01L21/60
Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To prevent the ends of wiring films from being deformed by extending an insulating film forming a base to the ends of the wiring films on the side where they are to be connected with the electrodes on a semiconductor device to reinforce the wiring films, and forming connecting holes in areas where connection with the electrodes are to be made, back from the ends of the wiring films. SOLUTION: The base 1 of a lead frame is extended so that the tips of the inner lead sections of leads 2 will be covered, and contact holes 7 are formed only in portions 3 that must be exposed to connect with the electrodes on a semiconductor device. Since the base 1 covers the inner lead sections of the leads 2 to the extent that the tips of the inner lead sections are also covered, the entire inner leads, including their tips, are completely reinforced. This eliminates a possibility that deformation, such as bend, in the inner leads is caused. As a result, it is possible to prevent improper connection with the electrodes on the semiconductor device and short-circuiting.

Title: Directly coupled controller of fluid transmission device in automatic speed changer for vehicle
Inventor: NISHIKAWA MASAO
IPC: F16H61/14
Filed: 1984-02-06
Abstract: PURPOSE:To relax a stiff feeling when a directly coupled mechanism is released while a car is driven running at a high speed, by changing the reference value as a variable varying in relation to a car speed. CONSTITUTION:A governor valve 56 is provided as a means, outputting an index signal representing a car speed, so as to output a governor pressure Pg to a pilot oil path 61 from the governor valve 56, and the pilot oil path 61 is connected to pilot paths 68, 69, 70 of the first, second and the third shift valves 64, 66, 67 and to a port 82g of an idle release valve 82. In this way, a directly coupled mechanism, though it is a device able to perform directly coupled operation from a low speed range of small running resistance, enables a stiff feeling to be relaxed when the directly coupled mechanism is released while a car is driven running at a high speed by increasing the pressure, which releases the directly coupled mechanism, as the running resistance increases, because a reference value can be changed as a variable varying in relation to the car speed.

Title: Electromagnetic type loudspeaker
Inventor: WATANABE HIROYUKI
IPC: H04R13/00
Filed: 1982-02-10
Abstract: PURPOSE:To improve resisting properties against high input and high temperature of an electromagnetic loudspeaker and easily produce the loudspeaker, by fitting a magnet so that the direction of the magnetic pole becomes normal to the diaphragm and installing a ring hole coil near the magnet so that the core of the coil coincides with that of the magnet. CONSTITUTION:A permanent magnet 1 is joined with a diaphragm 2 and a coil 3 is set so that the core of the coil 3 coincides with the magnetic pole. When such a constitution is applied, it becomes possible to improve the efficiency of this loudspeaker, because the coil 3 is fixed and, therefore, the number of winding can be increased. Moreover, the coil can be worked into one having a radiating property so as to protect the damage due to high inputs and high temperature. In addition to the above, because of absence of any air gap, the permanent magnet 1 does not contact with the coil 3 even when the diaphragm makes a large motion. It is admissible to keep a clearance of about 3mm. between the permanent magnet 1 and the coil 3 and, therefore, the yield can be increased.
