Title: Magnetic recording and reproducing circuit
Inventor: KOSUGE MINORU
IPC: G11B5/09
Filed: 1985-11-05
Abstract: PURPOSE:To obtain a highly reliable reproducing data by setting a positive/negative threshold value with a prescribed ratio and a zero level to an envelope of a reproducing output in a form differentiating a data so as to detect that the reproducing signal crosses the positive/negative threshold continuously thereby deciding a zero cross detection signal generated in the detection as an effective data. CONSTITUTION:A head 4 reads a data of a medium 1 as a reproducing signal (a), the result is differentiated (11) to convert the peak as a zero cross point thereby correcting the amplitude. The positive/negative threshold values (x), (z) with a prescribed ratio to an envelope of an output (b) and a zero level (y) are generated (15) respectively, the output (b) is sliced by the threshold values (x), (z) to form outputs (c), (d). On the other hand, the output (b) is compared with the zero level (y) to generate (14) a zero cross detection signal (f). The signal (f) corresponds to the peak of the reproducing signal (a) and an ineffective pulse A is to be generated. A logic circuit 16 inputs the outputs (c), (d), (f) and recognizes an effective reproducing data (i) to give an output. Through the constitution above, the effect such as a noise (n) the reproducing signal of a magnetic head is excluded to obtain a reproducing data with high reliability.

Filed: 1988-09-30
Abstract: PURPOSE:To extremely reduce burrs by so punching beforehand a stripelike material that the interval of leads becomes slightly smaller than its object size, and then finish punching it so that the internal becomes the object size. CONSTITUTION:A first mold so formed that the interval of leads becomes slightly smaller than its finishing size is mounted on a stripelike material, and a lead frame having the internal of the leads slightly smaller than its finishing size is so patterned by pressing as to be designated by broken lines (r). Here, solid lines (c) denote finishing size. Then, a second mold so formed that the interval becomes that of the finishing size is mounted, and a lead frame of finishing size is patterned by pressing. It is so coined in the degree of collapsing the burrs at the ends of inner leads 12 in the second mold, and the surface is flattened. In the frame formed in this manner, the burrs are almost wholly eliminated, do not affect the interval of the leads, and its sufficiently effective planar width can be obtained.

Title: Refrigerator
Inventor: KUSUMOTO NOBUHIRO
IPC: F25B1/00
Filed: 1987-10-01
Abstract: PURPOSE: To enhance reliability of refrigerating operation by closing the opposite ends of a part of heat exchanging section of an air-cooled condenser when refrigerating operation is continued under low outer air temperature and returning refrigerant from the part of heat exchanging section back to the low pressure side of a refrigerant circulation system. CONSTITUTION: When the outer air temperature is low, a blocking means 9 closes the opposite ends of a part of the heat exchanging section of condensers 2, 3 through a control means. Since refrigerant flows except a part of the heat exchanging section of the condensers 2, 3 in a refrigerant circulation system A, condensing performance of the air-cooled condensers 2 3 deteriorates to suppress lowering of high pressure thus sustaining refrigerating operation well. In this regard, the part 2 of the heat exchanging section of the condensers 2, 3 blocked by the means 9 communicates through an equalizing means 12 with the low pressure side of the system A to return refrigerant back to a compressor 1.  Consequently, liquid refrigerant is prevented from standing thereat and deficiency of liquid pressure or circulation oil in the compressor 1 is eliminated resulting in the enhancement of reliability of refrigerating operation.

Abstract: PURPOSE:To prevent a characteristic change due to a thermal and a mechanical cause by bonding a semiconductor substrate having a very small air gap and a piezoelectric substrate through hydrophilic picture and overlapped heat treatment so as to obtain a stable air gap. CONSTITUTION:Etching is applied to a semiconductor substrate 1 made of a silicon or the like to a depth of e.g. 50nm to form a thick part 7. The piezoelectric substrate 2 and made of a lithium niobate single crystal or the like and the thick part 7 are opposed to each other. The surface of a adhesion support section 8 is subject to hydrophilic processing by using a liquid such as a mixed liquid of ammonium-hydrogen peroxide. A strong adhesive state is obtained by overlapping both sides and they are heat-treated for an hour at, e.g. 300 deg.C. The adhered boundary is the adhesion in the order of atoms and the recessed part formed by etching is realized as a gap 6 accurately without any change. A signal received from interdigital input electrodes 3,3' causes displacement of charges on the surface of the semiconductor thereby providing an output from an output electrode 4.

Title: Semiconductor integrated circuit

IPC: H01L21/822
Filed: 1989-09-27
Abstract: PURPOSE:To suppress variation in a substrate potential and to improve reliability by switching in two ways the substrate bias voltage limiting level of a substrate bias level limiter at the times of turning ON a power source and normally operating. CONSTITUTION:The output LMT of a substrate bias level limiter 12 becomes 'L', the output P of an initial limiting pulse detector 13 becomes 'H' at the time of turning ON a power source, and the substrate bias limiting level of the limiter 12 is set to V1 lower than the limiting level V2 of the substrate bias at the time of normal operation. If a substrate bias generator 11 is started to be operated, the limiter 12 outputs an 'H' signal LMT when the substrate potential is lowered to the V1. Thus, the generator 11 is stopped, the output P of the detector 13 becomes 'L', and the substrate bias limiting level of the limiter 12 is switched to becomes the V2. Thus, even if the substrate potential is floated by capacitive coupling, the potential is recovered to a predetermined optimized value. Accordingly, variation in the potential is suppressed to improve reliability.
