Title: Printed wiring board, formation of conductor pattern therefor and adhesive sheet
Inventor: OKUMURA MANABU
IPC: H05K3/38
Filed: 1993-11-08
Abstract: PURPOSE:To easily and reliably form a conductor pattern excellent in adhesion to resin insulating layer. CONSTITUTION:First adhesive layers 2a for additive, containing Pd catalytic nuclei 7 as catalytic nucleus, are formed on an inner board 1 having an inner conductor pattern 1a thereon. Second adhesive layers 2b for additive, containing no Pd catalytic nucleus, are deposited on the first adhesive layers 2a for additive. A large number of recesses 3 for anchoring are formed by roughing the resin insulating layers 2 composed of these adhesive layers 2a, 2b. The spaces inside the recesses 3 for anchoring extend to the first adhesive layers 2a for additive. After applying plating resist 6, electroless copper plating is performed to form outer conductor patterns 5 on the resin insulating layers 2. As a result, no cavity is formed in the center of copper plate 5a deposited in the recesses 3 for anchoring, which improves the peeling strength of the outer conductor patterns 5.

Title: Manufacture of semiconductor device
Inventor: MITSUI KOTARO
IPC: H01L21/78
Filed: 1988-11-05
Abstract: PURPOSE:To prevent the generation of cracks in a semiconductor layer after element isolation by a method wherein, when the element is cut out from an epitaxial water composed of a semiconductor layer whose material is different from a substrate, the semiconductor layer in the vicinity of a part turning to an element boundary is previously and selectively eliminated. CONSTITUTION:An epitaxial GaAs layer 10 in the vicinity of an element boundary 7 is selectively eliminated. As a result, an Si substrate surface 1a is exposed in the vicinity of an element boundary 7, and individual LED pellets are separated by cutting the substrate from the exposed Si substrate surface 1a with a dicing saw 8. The dicing sm 8 of about 40mum width can be ordinarily used. Since the epitaxial GaAs layer 10 of 100mum width has been eliminated, the Si substrate 1 can be cut while the dicing saw does not come into contact directly with the epitaxial GaAs layer 10. Thereby, the mechanical stress caused by the dicing saw 8 at the time of cutting is not applied to the epitaxial GaAs layer 10, so that the generation of cracks can be prevented.

Title: Changeover type variable power optical system
Inventor: NAKAYAMA HIROKI
IPC: G02B15/10
Filed: 1985-12-12
Abstract: PURPOSE:To obtain a changeover type variable power optical system which has its lens system reduced on the whole and also has a >=2 times power variation ratio and excellent optical performance by mounting an auxiliary lens system in a specific shape which has an aspherical surface in such a shape that the positive refracting power becomes weaker and weaker toward the lens peripheral part on the image surface side of a main lens system. CONSTITUTION:One lens surface of the auxiliary lens system II is made aspherical so that the positive refracting power decreases toward the lens peripheral part, thereby reducing a meridional image surface DELTAM. Namely, the refracting power to a beam is reduced by weakening the refracting power of the aspherical surface ASF to make corrections so that the meridional image surface approximates to an ideal image surface. When the aspherical surface is made convex, the radius of curvature is increased toward the lens peripheral part.

The short fibers, etc. of natural fibers such as cotton can be employed as the natural fibrous substance. Sulfosuccinic acid dialkyl ester salt, etc. such as sodium di-2-ethylhexyl sulfosuccinate are quoted as the usable penetrating agent. Accordingly, moisture is absorbed to the water- absorbing high molecular substance and the natural fibrous substance in a vinyl chloride resin by the action of the penetrating agent in the vinyl chloride resin layer, thus substantially preventing the remaining of moisture on the surface of the vinyl chloride resin layer.

Title: Magnetic recording medium
Inventor: MIZOO YOSHIAKI
IPC: C10N40/18
Filed: 1986-11-25
Abstract: PURPOSE:To obtain a magnetic recording medium having excellent lubricity by incorporating cyclic dimethylsiloxane into a magnetic recording layer. CONSTITUTION:The cyclic dimethylsiloxane of n=10-20 expressed by the formula is incorporated into the magnetic recording layer consisting of magnetic powder and binder at about 0.01-0.05 parts per 100 parts magnetic iron powder. The cyclic dimethylsiloxane has high volatility and evaporates from the medium when is the formula is <=10 and the satisfactory lubrication is not obtainable when n is >=20. Since this cyclic dimethylsiloxane has low compatibility with general resins, the same is considered to exist locally in the surface of the magnetic layer and to act to lubricate a head in spite of the extremely low content thereof. The abrasion loss and coefft. of friction of the head are, therefore, decreased and the medium having the extremely high lubricity is obtd.

Title: Method and apparatus for detection of drop in function of nitrogen oxides absorbing catalyst
Inventor: INAGAKI HIROSHI
IPC: F02D45/00
Filed: 1997-10-14
Abstract: PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which a drop in the function of an NOx absorbing catalyst can be detected by an NOx sensor. SOLUTION: When the control of an operation in a lean air-fuel ratio is started (S120), a timer is started, and a second pumping current IP2 which expresses the concentration of NOx in a gas, to be measured, in the downstream of an NOx absorbing catalyst, a sensor temperature TH, an intake-pipe negative pressure Pb and an engine speed Ne are detected repeatedly after a stand-by time Tw elapses (S130 to S160). When the detected value of the negative pressure Pb and that of the engine speed Ne are within an allowable change width, the relative value ΔIP2(=IP2-IP2o) of the second pumping current IP2 corrected on the basis of the sensor temperature TH to a second pumping current IP2o detected first after the timer is started is computed. When the relative value IP2 becomes larger than a fixed value Ic, the timer is stopped (S170 to S240).  When a timer value TO is smaller than a time threshold value Tth , a refresh request is output, and, when the value TO is larger than the time threshold value Tth , a catalyst burning-off request is output (S250 to S270, S200).
