Title: Production of composite metallic material
Inventor: FUKUMOTO TADASHI
IPC: B22D19/02
Filed: 1985-12-27
Abstract: PURPOSE:To reduce the time for molding under pressurization by preheating a preform consisting of a reinforcing material, loading the preform into the 1st die, pouring and pressurizing a molten base metal therein and loading the same into the 2nd die while maintaining the pressurization. CONSTITUTION:The die is preheated to a prescribed temp. and the preform X is loaded into the 1st die 1 after preheating. The molten base metal Y is then poured into the die from above the preform X and is pressurized by an upper ram 4 so as to be impregnated into the preform. The upper ram 4 and a lower ram 5 are thereafter lowered to move the impregnated body to the 2nd die 2 while the pressurization is maintained. The temp. of the 2nd die 2 is made lower than at least the temp. of the 1st die 1. The pressurizing force is made smaller and the preheating temp. of the preform X is made lower by preheating the die to the substantially high temp. Since the thorough impregnation is executed, the time for the molding under the pressurization is shortened by the above-mentioned method.

Title: Oscillation circuit and tuner circuit using the circuit
Inventor: YAMADA TSUTOMU
IPC: H03J5/02
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To optimize oscillation power and to improve mixer characteristics, etc., by outputting a control signal for driving a 2nd current source in addition to a 1st operating current only when an oscillation output level decreases below a reference value. SOLUTION: At the time of CATV reception, a bias SN is applied only to the current source transistor Q135 of oscillation transistors Q131 and Q134 at a supply terminal TN for a signal SN supplied at high level and a high-level signal S19 is not applied to the base of a transistor Q137, so that only the current I1 is an oscillation operating current. At the time of, for example, Hch reception, the oscillation output level which is outputted from a buffer amplifier and detected by a detecting circuit 18 becomes lower than the reference level VB supplied to a comparing circuit 19, which outputs a high-level control signal S19. Namely, the specific bias is applied to the base of Q137 and a current I2 further flows to a differential circuit. Consequently, I1 and I2 flow to the differential circuit to increase the operating electric power of the oscillation circuit.

Title: Method and equipment for automatic handwritten character recognition using static and dynamic parameter
Inventor: JIEROOMU RIIN BEREGAADA
IPC: G06K9/68
Filed: 1993-11-24
Abstract: PURPOSE: To provide a method and device for recognizing a handwritten character in response to an input signal from a handwriting converter. CONSTITUTION: Tablet data are generated and processed by the three independent sets of characteristic vectors for encoding shape information among input character information. Those characteristic vectors include the bit-mapped horizontal (x-axial) and vertical (y-axial) slices of input character data, and additional characteristic vectors for encoding absolute (y)-axial displacement from the base lines of the bit-mapped image. A recognition error due to a spatial or static processing is totally different from the recognition error due to a timely or dynamic processing. Moreover, those differences can be mutually compensated. As a result, the overall recognition error ratio can be sharply reduced by the connection of those two sources of the characteristic vector information. A method for connecting probability scores from the dynamic and static character models is provided.

Title: Sealed contact device
Inventor: KUZUMI HIDEKI
IPC: H01H1/66
Filed: 1994-11-28
Abstract: PURPOSE: To trip a finely fused contact by increasing the kinetic energy converted from the energy of a pressure contact spring and a return spring. CONSTITUTION: When a contact fine fusion occurs, a movable contact 3 and a fixed contact 6 are fused in one point or two points, and fixed during the excitation of a coil 10. When the excitation of the coil 10 is cut in this state, the contact 6 is apt to be returned by the spring force of a return spring 9, but can not be operated by the fusion, and a movable shaft 7 is apt to return by the portion of an overtravel and stop.  However, since the movable shaft 7 is connected to a connecting part 21, and also connected and fixed to a relay member CC, a movable shaft 12a, and a movable iron core 12, the kinetic energy converted from the spring load at the overtravel by displacing the movable shaft 7 from the maximum overtravel to the state having no overtravel becomes 10-20 times in the past because the mass is larger than in the past, and the finely fused contact can be tripped by this kinetic energy.

Title: Vertical type p-n-p transistor
Inventor: MISAKI KOICHIRO
IPC: H01L29/732
Filed: 1986-12-09
Abstract: PURPOSE:To reduce the thickness of an epitaxial layer significantly while inhibiting a spread in the lateral direction of an insulating isolation layer and to improve the degree of integration by lowering impurity concentration in a P-type buried collector layer under an active region in a vertical type P-N-P transistor. CONSTITUTION:A vertical type P-N-P transistor is shaped by a base consisting of an N-type epitaxial layer 105 surrounded by P-type collector leading-out layers 107, a P-type emitter layer 108 and a P-type buried collector layer 104. Impurity concentration in the P-type buried collector layer 104 is formed at a value smaller than P<+> type buried layers 103 and P<+> type buried collector leading-out layers 110. Consequently, pushing-up to the N-type epitaxial layer 105 is diminished, thus thinning the thickness of the N-type epitaxial layer 105 only by the pushing-up section. An extent in the lateral direction of a P-type insulating isolation layer can also be inhibited.

Abstract: PURPOSE:To aim at preventing normal electric discharge from being hindered due to aggregation of machined chips onto recessed and projected surface walls of an electric discharge machining electrode and a workpiece during the workpiece is bored by the electrode, by intermittently changing the rotational direction of the electrode to change the flowing direction of machining liquid. CONSTITUTION:When a workpiece 2 is machined to form a hole 13 therein, the rotational direction of the output shaft 9 of a motor 8 is intermittently changed by means of a timer 12 to intermittently change the rotational direction of an electrical discharge machining electrode 1. Accordingly, the flowing direc tion of machining liquid is changed to peel off machined chips which are liable to be adhered onto recessed and projected surfaces of the electrical discharge machining electrode 1 and the workpiece 2 so that the chips are suspended in the machining liquid 4, and therefore, the machined chips 14 may be succes sively discharged off outside of the hole 13 in addition to the agitation of the machining liquid 4. Accordingly, it is possible to easily form a deep hole having a micro-diameter of several hundred microns to several ten microns, which is useful particularly for working an ink jet nozzle.

It is also possible to move the sample by the sample scanning part 14 while the laser light and the detecting part 15 are fixed. In a signal processing part 16 which processes signals of the intensity of light of secondary higher harmonics, the film thickness data is output on the basis of the preliminarily input data indicative of the relationship between the intensity of light of secondary higher harmonics and the thickness of an indium tin oxide film. The film thickness data is displayed at a film thickness displaying part 17 together with the positional data of the film on the sample. All is controlled by a computer part 18.
