Title: Substrate holder
Inventor: MAEKAWA NAOTADA
IPC: H01L21/673
Filed: 1998-09-11
Abstract: PROBLEM TO BE SOLVED: To provide a substrate holder which can hold a plurality of substrates in stable attitudes, while securing wide openings, and at the same time, has sufficient strength even when the intervals among the substrates are narrowed. SOLUTION: A substrate holder has a plurality of holding grooves 93a. Each groove 93a has a pair of flat surfaces 93b, which spread out directed upwards from the bottom of the groove 93a and a pair of projecting curved surfaces 93c which spread out directed upwards from each of the upper end of the surfaces 93b. By making the surfaces 93c curved, the opening of the groove 93a becomes broader and the groove 93a can hold a substrate W in a stable attitude by holding the substrate W with the flat surfaces 93b. Furthermore, even if the intervals between the grooves 93a are narrowed, the portion 95 between the curved surfaces 93c are provided with sufficient strength, and the thickness of the portion 95 is increased.

Title: Liquid crystal display element
Inventor: SUGAWARA SEIZO
IPC: G02F1/1337
Filed: 1991-10-04
Abstract: PURPOSE:To eliminate the poorness in working efficiency caused by the handling of a phase difference plate and the poorness of display quality by forming a substrate layer having rugged shapes on a substrate and forming a film consisting of a high-polymer liquid crystal thereon. CONSTITUTION:The substrate layer 7 having the rugged shapes is formed on the substrate 1 and the high-polymer liquid crystal layer 8 is formed thereon. Then, the low-polymer liquid crystal group components of the high-polymer liquid crystal constituting the high-polymer liquid crystal layer 8 are oriented along the direction where the recessed parts (or projecting parts) of the rugged shapes of the substrate layer 7 when the high-polymer liquid crystal layer 8 formed on the substrate layer 7 is heated up to an isotropic liquid and is further slowly cooled to a nematic phase. The light passing through the high-polymer liquid crystal layer 8 generates a phase difference when the low-polymer liquid crystal group components of the high-polymer liquid crystal are oriented in one direction in such a manner. This phase difference is controllable by the film thickness of the high-polymer liquid crystal 8.

Title: Method of manufacturing semiconductor device
Inventor: SATO OSAMU
IPC: G03F1/38
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To surely detect characteristic defects, etc., caused by dimensional variations in one shot at exposure and in a short time, and improve the reliability of a semiconductor device. SOLUTION: When four semiconductor chips 2a-2d are exposed in a one-shot region SA at exposure time, TEGs 4a-4d are formed in the parts of a scribe region 3 near the respective corners of the one-shot region SA and a TEG 4e is formed in the part of the scribe region 3 at the center of the one-shot region SA. If the electrical characteristic defects of one semiconductor chip is detected when a semiconductor wafer 1 is subjected to a probe test, the characteristic defects of the defective semiconductor chip can be detected in accordance with the test result of the probe test in the TEG closest to the failure region or a dimensional variation in one shot, to realize quick feedback to a manufacturing process, so that the manufacturing yield of semiconductor devices can be improved.

Title: Mounting method of electronic component by reflow soldering
Inventor: NAKAOKA YASUYUKI
IPC: H05K3/34
Filed: 1987-10-13
Abstract: PURPOSE:To prevent both a bridge mode failure and an open mode failure, by positioning the tip end of a land section so as not to protrude forth from the head of a lead tip end. CONSTITUTION:A creamy solder 3 is previously printed on the lane section 2 on a printed wiring board 1, and the connection 6 of the lead 5 of an electronic component 4 is pressed against the surface of the creamy solder 3 to be attached thereto temporally. Next, the creamy solder 3 is molten by the irradiation of infrared rays or the like to connect both the land section 2 and the connection 6 each other through solder 8. Now, the tip end of the land section 2 is so positioned as not to protrude force from the head of the connection 6 of the lead 5. As a result, in the creamed solder 3 being molten, there is no flowing of the solder 8 from the tip end of the land 2 to the root part of the connection 6. Therefore, a bridge is effectively prevented from occurring between the adjacent lands. Accordingly, since the amount of the creamy solder 3 is not needed to be reduced in order to prevent the bridge mode failure, thereby an open mode failure can be also sufficiently prevented.

Title: Camera
Inventor: NISHINO NAOYUKI
IPC: G03B17/00
Filed: 1993-10-15
Abstract: PURPOSE:To provide a camera preventing the application of an excess load on a film and a winding mechanism by surely detecting the tailing edge of the film, without increasing components at a low cost. CONSTITUTION:When the perforation 4 of the next photographic frame is detected before the subtractively counted feeding time does not become zero, the photographic frame is set in the position of an aperture and the winding of the film 2 is completed. However, in the winding after the final photographic frame is photographed, even when a feeding time lapses, the perforation 4 does not exist so that when the subtractively counted feeding time of a timer circuit 12 becomes zero (the position corresponding to the leading part of the next photographic frame), a feeding motor is surely stopped. Thus, the film is not forcibly pulled and an unnecessary load is never applied to the winding mechanism.

Title: Method of discriminating ignition of burner
Inventor: IIDA MASAMI
IPC: F23M11/04
Filed: 1986-10-30
Abstract: PURPOSE:To positively make an ignition detection by dividing a flame area of a burner which is the object of an ignition discrimination into a plurality of sectors by an image sensor in a furnace provided with a plurality of burners and catching them, and comparing the lengths of black skirts for respective sectors with a reference. CONSTITUTION:A flame within a furnace is inputted to an image sensor 4 through a lens 1a, an image fiber 3, and a lens 1b. The output of the image sensor 4 is delivered to a signal processing section 5 with a luminance signal divided into a plurality of sectors, i.e., picture elements of 50 X 50 = 2,500 per one screen as a unit. A burner area to be detected is set at a burner area to be detected setting part 5a, and then the length of black skirts in each division is obtained at the black skirt length detecting part 5b, and the thus obtained black skirt length is sent to a judgement logic 5d. The judgement logic 5d judges ignition based on the black skirt length and average luminance level. Thus, ignition discrimination can be made positively.

The processes such as washing of the surfaces of the growing layers is not required. Thus the processes can be simplified.
