Title: Oxygen sensor
Inventor: IINO ATSUSHI
IPC: G01N27/407
Filed: 1984-12-06
Abstract: PURPOSE:To prevent the deterioration and injury of an oxygen sensor element owing to the intrusion of foreign matter by providing a hermetic space in the case of the oxygen sensor and communicating the same only with the gap in the oxygen sensor in which a reference electrode is provided. CONSTITUTION:The space 9 between a connector insulator 5 and a keep plate 18 and the space in which the contactor 5a of the insulator 5 is contained are mated to form the hermetic space 9. The space 9 is communicated only with the gap 35 in which the reference electrode 38 and a pump electrode 39 are contained through the spacing at the top end of the oxygen sensor element 1 and the insulator 5. A relatively large amt. of the atm. air which is the reference material can be accumulated into the hermetic space 9 communicating with the gap 35 having the electrode 38 of such oxygen sensor by the above- mentioned constitution and since the hermetic space is hermetically isolated from the outside, the intrusion of the foreign matter such as moisture and salt water into said space is thoroughly prevented.

Title: Multilayer circuit board
Inventor: TAKEUCHI MEGUMI
IPC: H05K1/02
Filed: 1990-09-27
Abstract: PURPOSE:To prevent the occurrence of cracks and disconnections in a conductive pattern by forming a bent section which obliquely CONSTITUTION:Through holes are provided at suitable locations of a film substrate made of a resin having heat deformation property and a conductive pattern 21 is formed on the surface of flat plate sections 20a and 20b other than a bent section by, for example, screen-printing conductive paste to a thickness of about 20mum The conductive pattern 23 is formed so that the pattern 23 can obliquely intersect the bending line of the bent section 22. When the intersecting angle is set at 30 deg. against the bending line, the width (w) of the pattern 21 intersecting the bending line is increased by about 15% and the bent cross section of the section 22 increases. Therefore, the conductive pattern is hardly disconnected at the bent section of the film substrate.

Title: Reflection type screen and its manufacture
Inventor: HONDA MAKOTO
IPC: G03B21/60
Filed: 1991-09-10
Abstract: PURPOSE:To provide the reflection type screen which can be manufactured at low cost and is bright up to the periphery to have a wide good-view range. CONSTITUTION:A reflecting surface 16 is formed on one surface of a substantially transparent substrate 12 and a Fresnel lens 18 consisting of a surface which does not include the center of the concentric circles of a circular Fresnel lens is formed on the other surface to constitute the reflection type screen 10. A die for forming the Fresnel lens is obtained by forming a layer to be cut outside a circularly conic roll across a peeling layer, peeling the cut layer after linear Fresnel cutting, and forming a flat plate. The Fresnel lens 18 does not have the Fresnel center, so reflected light becomes parallel and the screen which has uniform brightness is obtained. Further, the die is formed by peeling the external layer of the circularly conic roll, so the partial Fresnel die which does not have the Fresnel center is easily obtained at low cost.

Filed: 1987-10-14
Abstract: PURPOSE:To absorb errors due to the dispersion of elements to compose a circuit, and due to the fluctuation of an environmental conditions by correcting a value, in which the output of an amplifying means is compared with a reference value from an external part in a feedback system processing means, added and subtracted, with a value written to a storing means, and controlling the bias of the amplifying means based on the correcting value. CONSTITUTION:The connection of an input side and a feedback system is switched by switching means 50a and 50b so that the output of a feedback system processing means 20 in a prescribed sampling period just after a power source is inputted to an AGC circuit can be written as the characteristic of the AGC circuit to a storing means 30. Next, the input side and feedback system are restored, the output of an amplifying means 10 of an input signal 1 is digital-converted, and the mean value of the values in the prescribed sampling period is obtained. The value, in which the characteristic value or the AGC circuit written beforehand is weighted to the mean value, is impressed in making it into the bias control voltage of the amplifying means 10. Thus, the errors of the output of the amplifying means 10 generated due to the environmental conditions at such a time and due to the dispersion of composing elements can be absorbed.

Title: Method of designing semiconductor integrated circuit
Inventor: KAWAHISA KATSUE
IPC: H01L21/82
Filed: 1991-10-07
Abstract: PURPOSE:To lower the rate of design correction to be executed by a method wherein the delay time of each signal line is set within a prescribed range and, after that, the design is verified by means of a delayed logic simulation using a virtual wiring capacitance. CONSTITUTION:A logic designing operation is first executed; the virtual external load capacitance of each signal line is estimated from the number of fan-ins, the number of fan-outs and a virtual wiring capacitance. Then, the delay time due to an external load capacitance of each signal line is found. Steps S1, S2, S22, S25 to S28 are repeated so that the delay time can be set within a set range. When the delay time is within the set range, the designing method proceeds to Step 3; the design is verified by means of a delayed logic simulation using the virtual wiring capacitance. Thereby, the verification of the design by means of the delayed logic simulation using the virtual wiring capacitance is easily accepted, and it is possible to shorten the period from the logic designing up to the finish of the layout designing.

In succession, thermally molten resin is injected so as to produce the molded form A. When the molded form A is taken out, the bonded part of the thermoplastic resin is taken out together with the molded form A through the releasing of the thermoplastic resin layer 21 from the biaxially stretched resin layer 23 due to the releasable resin layer 22, resulting in leaving the non-bonded part of the thermoplastic resin in the mold 10.

Abstract: PURPOSE: To form a surface flat to a condyloid projection of a femur by fixing a femur distal end plate for exposing condyloid projections of an inner and outer sides of the fumur with drill pins, mounting on the plate with a distal end grinder and driving the grinder. CONSTITUTION: First, a guide bushing 32, a bushing guide block, and femur distal region plate body 12 are assembled, and an intramedullary rod 40 is passed through the bore 34 of the bushing 32 into a medullary canal 76 in a femur 60, upon which the assembly is advanced distally by the rod 40 into contact with condyloid projections 62 and 64. Secondly, drill pins 66 are inserted in all the four holes in a flange 16 and are driven into the sides of the condyloid projection to hold the plate body 12 stationary. Thirdly, the assembly is disintegrated and the rod 40 is removed away, and a distal-region-grinding guide body is set in the plate body 12 and locked there. Lastly, a distal end grinder is inserted in a circular bore through the guide body. Those procedures allow the surgeon to form a surface large and flat to the condyloid projections 62 and 64 at the femur distal region.

Title: Measuring device
Inventor: SUGITA MITSURU
IPC: H03K17/28
Filed: 1987-10-14
Abstract: PURPOSE:To prevent an erroneous recognition by recognizing a reading state, delaying a data fetch time during a reading, thereby, eliminating the change of the value of a measuring register during the reading. CONSTITUTION:When a fetches signal CAP from the counter 1 of a pulse duration measuring type timer is inputted, the signal CAP passes through a path 8 in a fetch signal control circuit 3 and is outputted as a fetch permitting signal (a) from an OR circuit 10. Thereby, the count value of the counter 1 is fetched to the measuring register 2. Then, when the signal CAP is inputted during the reading by a signal RD, the signal CAP enters a one cycle delay circuit 4, is delayed until the reading operation is completed and outputted as the delayed fetch permitting signal (a). Thereby, the value of the measuring register is not changed during the reading operation to stably execute the reading operation.
