Title: Semiconductor device
Inventor: TOBA SUSUMU
IPC: H01L25/07
Filed: 1997-01-08
Abstract: PROBLEM TO BE SOLVED: To ensure sufficient dielectric strength between the terminal frames of the main terminal, while reducing sealing resin filled in a package. SOLUTION: A package has a power circuit block 2 formed by mounting a plurality of power semiconductor elements on an insulating board. An input/ output main terminal 5 inserted into the outer resin case 4 of the package is extracted and arranged on the case top peripheral area, and a terminal frame 5a extracted into the case is laid to the upper part of the power circuit, the leg of the terminal frame 5a is bonded to the power circuit part with solder and the power circuit is resin-sealed by filling the package with sealing resin 7.  In this case, the base of the terminal frame 5a, which is extracted from the inner wall of the resin case to the package inside to be wired at the upper part of the power circuit, is lowered by ΔH from a height H, which is a wiring height from the base to the top, to be at a level L2 to be buried in the layer of the applied sealing resin, and dielectric strength between the terminal frames 50 is ensured.

Title: Method for preventing occurrence of incomplete ice in ice making machine
Inventor: YATORI MASAHIDE
IPC: F25C1/00
Filed: 1989-01-09
Abstract: PURPOSE:To prevent any cotton ices from being produced in an ice making machine by a method wherein either a solenoid valve for refrigerant or an expansion valve in a freezing circuit during its working condition is closed until a low pressure of a freezing circuit or a temperature in an evaporator is decreased to a specified value. CONSTITUTION:In case that during an ice making cycle, a temperature sensor for use in sensing a temperature of ice making water near a water collecting gutter detects a variation for expecting an occurrence of incomplete ice, for example, such a temperature as one in which the temperature is gradually decreased to detect a temperature in a range of 0 deg.C to 1 deg.C, a solenoid valve 18 for refrigerant is kept closed in response to the detected signal until a temperature sensor 20 at an inlet of an evaporator 15 is rapidly decreased to several minus temperatures  deg.C. A temperature of an ice making plate to be cooled by the evaporator 15 under a rapid decreasing of a gas pressure of refrigerant is rapidly reduced, resulting in that a temperature difference between the ice making water and the ice making plate is increased rapidly, resulting in that a core required for growing a normal ice is produced at a surface of the ice making plate where the cotton ice may easily occur. In addition, a gas pressure at the low pressure part is in a proportional relation with the sensed temperature of the temperature detector 20 at an inlet part of the evaporator 15. Even if the pressure switch 19 is set at such a low pressure as one where the temperature of the evaporator 15 shows several minus degrees  deg.C, quite a similar action and effect can be attained.

IPC: H04S1/00
Filed: 1978-01-10
Abstract: PURPOSE:To eliminate the feeling of physical disorder and let an electrostatic type transducer serve also as a boosting transformer in the headphone by said transducer which uses a transformer in synthesizing the sounds of the antiphase components of right and left sounds in stereo signals. CONSTITUTION:This refers to the synthesizer which synthesizes the respectively antiphase components of the left and right audio signals L, R in stereo signals by applying the same to the other sides by using a transformer T1 having mutually oppositely coupled magnetic paths M1, M2, wherein if the left and right signals L', R' being derived from the secondary winding of the transformer T1 are supplied to the headphone the localization of sound image will localize not backward above the head as with conventional headphones but in the space outside the head and therefore it becomes equivalent to that when speakers are used thus said signals may be listened to as natural sounds which do not associate any feeling of physical disorder.

Title: Constitution of two-dimensional pattern discriminator
Inventor: INAZUMI MITSUHIRO
IPC: G06T7/00
Filed: 1988-01-07
Abstract: PURPOSE:To simplify the constitution of a two-dimensional pattern discriminator by discriminating a two-dimensional pattern via a one-dimensional pattern discriminating mechanism of a simple constitution and with no use of a large memory. CONSTITUTION:Images inputted/from a one-dimensional image input device 1 are mapped to a single analog value by a mapping function 2 and inputted to an analog shift register 3 with synchronism by a synchronizing function 4. A one-dimensional pattern discriminator 5 discriminates patterns with the parallel output of the register 3 defined as an input. Thus it is possible to discriminate a two-dimensional pattern by the discriminator 5 of a simple constitution with no use of a large memory for storage of a two-dimensional pattern. Then the constitution of a two-dimensional pattern discriminator is simplified.

Abstract: PURPOSE:To develop a B-contg. low-alloy steel having excellent strength and toughness by subjecting a low-alloy steel contg. a slight ratio each of Al and B to a heat treatment, hot working and hardening and tempering treatments under specific conditions. CONSTITUTION:The B-contg. low-alloy steel contg. 0.02-0.15% Al and 0.0003-0.0050% B is used as a steel material for a pipeline for which high strength and high toughness are required. The ingot of such steel is forcibly cooled at >=10 deg.C/min average cooling rate until the temp. of the ingot decreases to 600 deg.C to prevent the precipitation of coarse network AlN. The ingot is further heated to 1,000-1,180 deg.C and is hot rolled. The hot rolling is ended at 950 deg.C to fix the N in the steel as AlN and to prevent the formation of BN, thereby solutionizing the B. The rolled sheet is reheated at >=25 deg.C/min heating rate and is subjected to hardening and tempering, by which the hardenability by the solid soln. B is improved and the low-alloy steel having the excellent strength and toughness is produced.
