Title: Semiconductor package
Inventor: YAMADA MASAHIRO
IPC: H01L23/29
Filed: 1990-11-28
Abstract: PURPOSE:To improve heat releasability by forming a hole which reaches a lead frame on the part of a package and fixing a metal piece in the hole. CONSTITUTION:Resin mold material 103 forms the package main body. A hole 104 for fixing a heat sink 105 on the package main body is permitted to make contact with the rear plane of the TAB part of the lead frame so as to improve the effect of heat release to the heat sink 105. As for the material of the heat sink 105, copper, which has excellent heat conductivity, 42 alloy which is the material of the lead frame 12, etc., are suitable. The heat sink 105 is fixed to the fixing hole 104 by using epoxy adhesive. This improves the heat releasing efficiency of a device in a plastic flat package (PQFP) having many pins of a short pitch.

Title: Gear pump
Inventor: ITO MOTOYA
IPC: F02M37/08
Filed: 1991-12-12
Abstract: PURPOSE:To provide an easily-manufactured gear pump by which a fluid film is formed stably in a sliding part and abrasion caused by a direct contact or noise caused by the abrasion and a pump efficiency drop can be prevented. CONSTITUTION:Recess parts 13a and 14a formed on respective concentric circles on both end surfaces of an inner rotor 13 and an outer rotor 14 are formed independently so as to close from respective teeth surfaces of the external teeth surface of the inner rotor 13 or the internal teeth surface of the outer rotor 14, and are communicated temporarily with a suction port 21 or a delivery port 22 when they are rotated. When they are rotated, fuel is filled while the recess parts 13a and 14a are communicated with the suction port 21, and when the recess parts 13a and 14a becomes uncommunicated with the suction port 21, the filled fuel in these recess parts 13a and 14a is supplied to a slidably contact surface between the inner rotor 13 and the outer rotor 14. Since the recess parts 13a and 14a are formed in a groove shape closed toward the teeth surfaces, an oil film can be formed effectively due to the possessing fuel in the groove, so that abrasion caused by a lack of the oil film can be prevented.

Title: Method of testing susceptibility to carcinostatic
Inventor: YAMAMOTO KATSUE
IPC: C12N15/09
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To test the susceptibility of cancer cells to carcinostatics in order to judge the resistance ability of the cancer cells to the carcinostatics by detecting the expression amount of a gene in heat shock protein 75 (mt HSP 75) localized in mitochondria. SOLUTION: The susceptibility of cancer cells to carcinostatics is tested by detecting the expression amount of a gene in heat shock protein 75 (mt HSP 75) localized in mitochondria by the use of northern plotting for the transcriptional product of the gene in mt HSP 75 or western plotting for the translation product of the gene in mt HSP 75, because the expression amount of the gene in mt HSP 75 increases in the cancer cells which show resistance to carcinostatics, e.g. cisplatin and the like, and is on a low level in the cancer cells which show susceptibility to carcinostatics. Further, by this susceptibility test for carcinostatics, it is possible to previously judge whether the cancer cells have resistance ability to carcinostatics or not and more effectively carry out treatment.

IPC: G06F9/38
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To provide a method and device for preventing the operation of a processor from being interrupted when the capacity of a buffer is full. SOLUTION: A protocol issues an instruction so that a load buffer 60 can always attain superiority until a store buffer 61 reaches a constant high standard 62.

When the store buffer 61 reaches the high standard 62, the store buffer 61 always obtains the priority order until it falls to the low standard. The load buffer 60 always attains superiority when it is beyond a high standard 63. When the load buffer 60 is below the high standard 63, the load buffer 60 attains superiority until the store buffer 61 reaches the high standard 62. The store buffer 61 obtains the priority order, and maintains the priority order until the load buffer 60 reaches the high standard 63.

Title: Formation of photomask and resist pattern and semiconductor element
Inventor: HASEGAWA NORIO
IPC: G03F1/30
Filed: 1992-12-11
Abstract: PURPOSE:To prevent the size reduction of patterns in size changing parts and to enable the use of the patterns near the resolution threshold even for the intricate patterns by arranging light shielding patterns within the large transmission patterns neat the junctures of transmission patterns near the resolution threshold and the large transmission patterns. CONSTITUTION:The short size A of the first aperture pattern 2 to be used for stepping and to be resolved is A=lambda/(2XNA) or below (where lambda = exposing wavelength, NA = numerical aperture of a projecting lens). The pattern arranging with the light shielding pattern 4 in proximity to the juncture with the pattern 2 in the second aperture pattern 3 arrayed in connection to the pattern 2 is included in the case of the synthetic graphic patterns in which a level difference exists between the above-mentioned first aperture pattern and the second aperture pattern 3. The excess light in the pattern neck part is, therefore, suppressed and the intensity of unnecessary diffracted light is lowered. As a result, the generation of the constriction of the patterns is prevented and the arrangement of the patterns adjacent to each other at fine spacings is possible. Dealing with the intricate patterns is possible as well.
