Abstract: PURPOSE:To prevent occurrence and increase of crystal defects in the semiconductor crystal formed in a plurality of semiconductor elements such as a Gunn diode, an  IMPATT diode and the like and increase the yield of the semiconductor elements  by dividing the semiconductor crystal into a plurality of pieces and plating heat dissipating metal on the back surfaces of the respective pieces. CONSTITUTION:A high resistance n-type GaAs operation layer 2 and a low resistance n-type GaAs layer 3 are sequentially epitaxially grown on an n-type GaAs substrate 1, Au.Ge or the like is coated on the surfaces of both the substrate 1 and the layer 3, respectively and alloyed to form ohmic electrodes 4, 5, respectively thereon. The entirety is scribed and divided into a plurality of pieces 11 to become, for example, Gunn diodes. The pieces 11 are aligned at suitable interval on a conductive film 12, and formed with plated heat sinks 13 on the back surfaces of the respective pieces 11 by an electrolytic plating process. When using the pieces 11, they may be separated from the conductive film. Thus, the stress applied to the crystal at radiator forming time is dispersed to the respective pieces and reduced so as to decrease the occurrence of crystal defects.

IPC: B65H3/06
Filed: 1988-02-22
Abstract: PURPOSE:To enable reliable separation and carriage from a thick sheet to a thin sheet by varying overlap of a carrying roller and a separating roller based on the thickness of the sheet. CONSTITUTION:A detector comprises a pair of rollers 3 pressure contacting each other with one roller supported movably in radial direction and a sensor 5 for detecting the distance between the axes of the carry rollers, where the sensor 5 is coupled to a control section 6.

Title: Preventing device for misoperation for tape recorder or the like
Inventor: ISHIYAMA YOSHIO
IPC: G11B15/04
Filed: 1980-03-31
Abstract: PURPOSE:To prevent the response to misoperation due to feather touch type switch, by difficult the switching to the changing operating mode due to misoperation, through the activation of load of buffer in response to the operation of operating buttons. CONSTITUTION:When the switch 5' or the like is closed through the operation of the recording button 5 or the like, high-level recording control signal is produced from the control circuit 6 into recording mode, and the output of the circuit 9 is inverted to high level via the OR circuits 7, 8 and AND circuit 9 to excite the plunger 10 and the buffer member 11 is moved to be activated. Thus, even if the fast forwarding button 4 is operated, the switch 4' is not closed with a light touch operation as far as the synthesized force between the spring force of the buffer spring 114' and the operating force of the switch 4' is not exerted, allowing to avoid the response of mode change due to misoperation of feather touch type switch.

Title: Semiconductor device
Inventor: SAKAMOTO AKIRA
IPC: H05K3/34
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To enhance connection reliability by forming the forward end of a lead terminal semicircularly or polygonally thereby increasing the bonding area of a conductive material. SOLUTION: A conductive material 5 connects the lead 6 of an SON package electrically with a pad 4 and can enter into the cross-section of the lead 6 having semicircular 6a forward end. Since the lead 6 of the SON package has semicircular 6a forward end and the side of at the semicircular part of the lead 6 is also plated with a conductive metal, the conductive material 5 can also adhere to the side face of semicircular 6a lead when the lead 6 having semicircular forward end is bonded to a pad 4 on a board 3 through the conductive material 5. Consequently, connection reliability can be enhanced by increasing the bonding area of the conductive material 5.

Title: Turbine casing supporting structure
Inventor: MATSUO ASAHARU
IPC: F01D25/28
Filed: 1994-03-11
Abstract: PURPOSE:To reduce movement of a casing at the time of operation so as to prevent generation of vibration by extending a casing lower-half part flange toward a side direction, extending a part of a concrete base upward, fastening steel made base plate on the top surface thereof, and mounting the flange on the base plate. CONSTITUTION:A turbine casing is constituted in such a way that half- cylindrical steel made casing upper-half part 1 and casing lower-half part 2 having flanges 4, 21 which are projected toward sides respectively are joined with each other on a flange part. The casing lower-half part flange 21 is extended toward the side, and also a part of the concrete base 22 is extended upward. A steel made base plate 24 is fastened with the extended upper surface, the easing lower-half part flange 21 is mounted on the base plate 24, so that the turbine casing is supported on the base 22. The height of a steel part is short, and the base plate 24 is apart from the casing. The base 23 which is extended upward is made of concrete. Since thermal elongation in vertical direction is small as a whole, upward movement of the casing is reduced, and vibration generation is prevented.

Title: Ventilator for internal-combustion engine
Inventor: AOKI KANETAKE
IPC: F01M13/00
Filed: 1984-03-02
Abstract: PURPOSE:To prevent oil particles from flowing into an intake line, in a ventilator, which introduces blow-by gas out of a crankcase into an intake manifold to control the internal pressure of the crankcase, by sharply changing the direction of flow of the blow-by gas to separate the oil particles from the gas. CONSTITUTION:When the internal pressure of a crankcase has become equal to or higher than a prescribed level during the run of an engine, a diaphragm 24 is moved up against a spring 32 by the pressure of a pressure chamber 25 communicating with the interior of the crankcase through an inlet port 27, so that a valve 31 is separated from a seat 33. As a result, blow-by gas enters into an outlet pipe 29 from the pressure chamber 25 and then flows out into an intake manifold through an outlet port 30. At that time, since the direction of flow of the blow-by gas is sharply changed, oil particles are separated from the blow-by gas due to the gravitation of the oil particles, so that the oil particles drop into an oil reservoir 35 and is temporarily stored therein. When a check valve 37 is opened due to the weight of the separated oil, the oil is returned to the crankcase.

Abstract: PURPOSE:To retain the locus of a detection point into spiral with a constant pitch interval and a tangent scanning speed constant by maintaining the peripheral speed of the locus of the detection point constant as well as detecting the rotary angle to control a rotary base into one direction movement. CONSTITUTION:A pulse motor 32 is used as a motor for driving an X table 6 and driven by a rotary angle information from an angular detector for detecting the rotary angle of a rotary base 4 so that the locus of the detecting point may become spiral with a constant pitch interval on a specimen. The position of the table 6 is calculated from the feeding mount of the table 6 to control the rotary speed of a variable speed motor 27 for driving the rotary base using the position value. Even if any disturbance occurs, it can be thus inspected without fail on the entire surface of the specimen, and it does not decelerate the peripheral speed even at the center so as to shorten the inspecting time.

Filed: 1989-02-20
Abstract: PURPOSE:To accurately detect a recording data even when a light output is varied due to internal and external dominant causes by providing an output control circuit capable of outputting a semiconductor laser in attenuating its variable frequency component and making no response to its data frequency component. CONSTITUTION:The subject device is composed of an output setting circuit SC and a semiconductor laser output control circuit (APC circuit) formed with a control loop (AC, LF, GC and IV), and a semiconductor laser LD and a photo detector PD are connected into the APC circuit. The laser LD is driven in response to a setting output from the circuit SC, and a variation of the laser output to be in response to return light via a recording surface is detected by the detector PD. The APC circuit is operated in such a manner that the variable frequency component S1 out of frequency components of a light output to be given to the detector PD from the laser LD is largely attenuated to be outputted, and the data frequency component S2 is outputted as it is. By this constitution, the component S2 is never amplitude-modulated by the component S1, and the recording data accurately is reproduced based on a detecting output of the detector.
