Abstract: PURPOSE:To prevent a sealing material from peeling from a lead frame by providing a groove processed parts in the surface, whereon a semiconductor element is mounted, of the lead frame or the surface on the opposite side. CONSTITUTION:Groove processed parts 1 are provided in the surface, whereon a semiconductor element is mounted, of a lead frame or the surface on the opposite side so that such a sealing material as ceramic, plastic and glass materials is well adhered on the lead frame. As the groove processed parts 1, any groove processed parts can be arbitrarily selected so long as the planar form of each groove processed part is a form in such a state that linear forms, round forms, triangles, quadrangles or polygons are arranged in a lattice type or arranged in a zigzag form and also, the depth of the grooves is within the extent of never damaging the functions of the lead frame. The groove processed parts 1 are particularly effective when being performed on the back side 2 of the semiconductor element mounting part. Thereby, the peeling of the sealing material is prevented after a molding is performed and it can be completely prevented that the air, water content and so on intrude along the lead frame from the outside and the functions of the semiconductor element are reduced.

Title: Refractive index measuring apparatus
Inventor: INOUE SUSUMU
IPC: G01N21/41
Filed: 1987-02-26
Abstract: PURPOSE:To measure refractive index easily and accurately without working or destroying an object to be measured, by irradiating the cylindrical transparent object being measured with a parallel light beam to measure the width of a dark portion generated in a projection boundary of the object being measured in an image reaching an imaging means. CONSTITUTION:Light from a light source 2 is turned with a collimation lens 3 to a parallel luminous flux with a specified width; a part of the light irradiating an object 1 to be measured projects a shadow of the object 1 being measured in an imaging system B as transmission light, and the other part thereof as that passing through the object 1 being measured to reach the imaging system B. In the imaging optical system B, an image of the object 1 being measured is picked up with a TV camera 5 through a photographing lens 4 to be projected on an CRT monitor 6. The passing light not transmitted through the object 1 being measured travels straight to reach a point on the focal plane of a photography system, while the transmission light is refracted according to refractive index of the object 1 being measured so that the passing light and the transmission light fails to reach some areas on the focal plane in the photography to form dark portions at both edges of the image of the object 1 being measured. Thus, the refractive index of the object 1 being measured can be learned by measuring the width of the dark portion.

Title: Production of polyamide porous membrane
Inventor: KURUSU KUROSHI
IPC: C08J9/28
Filed: 1979-04-12
Abstract: PURPOSE: To obtain a polyamide porous membrane having stable gas permeability, by evaporating a methanol-moistened polyamide membrane formed from a calcium/ methanol solution of the polyamide to vaporize a specific amount of the methanol and washing the membrane with water.  
     CONSTITUTION: A nonwoven fabric is immersed in a bath containing a calcium chloride/methanol solution of a polyamide, kept at a moderate temperature. Then, the fabric is withdrawn from the bath through a slit having an appropriate clearance and passed through a drying cylinder where the membrane is blown with hot air from both sides and 35W65wt% of the methanol contained in the moistened membrane is vaporized. Then, the membrane is immersed in water to remove the remaining methanol and calcium chloride. Thereby, a soft porous membrane is produced. When the amount of methanol vaporized is below 35%, the membrane has neither surface smoothness nor desirable gas permeability. On the other hand, when the amount exceeds 65wt%, the membrane becomes brittle and the permeability of the membrane is lowered.

Abstract: PURPOSE:To set the control of a noise removal circuit to be satisfactory with simple circuit constitution by executing control in accordance with the error flag of an error correction circuit so as to return a signal to a correct PCM sound signal. CONSTITUTION:The pulse of the error flag in the error correction circuit of a PCM decoder 2 is supplied to an integrating circuit 16. It obtains a pulse as a DC detection signal corresponding to a duty ratio and supplies it to the variable gain amplifier circuit 1e of the noise removal circuit 1 as a gain control signal. When a C/N value is deteriorated, the duty ratio in the high level of the error flag becomes large, and a DC detection signal becomes large. Since the circuit 1 is controlled in accordance with the error flag of the error correction circuit provided for the PCM decoder 2, the DC detection signal obtained through the circuit 16 is proportional to the C/N value of an input signal. Thus, the circuit 1 is controlled by the C/N value and noise removal quantity increases in accordance with the deterioration of the C/N value. Then, the detection circuit of the detection value of the C/N value becomes unnecessary, and the circuit 1 can satisfactorily be controlled with simple constitution.
