Title: Disk reproducing device
Inventor: YAMAMOTO HIDEO
IPC: G11B19/22
Filed: 1990-04-11
Abstract: PURPOSE:To surely stop the rotation of a disk by detecting the rotation direction by a signal obtained by A/D conversion of the impressed voltage of a spindle motor to impress a voltage of the opposite rotation direction to the spindle motor at the time of not reading out a signal from the disk. CONSTITUTION:The signal read out by a pickup 5 is inputted to a controller 1 through a signal processing device 2, and the controller 1 discriminates whether the signal is read out by the pickup 5 at present or not. When the mode is switched to the stop mode in the case of the absence of the read signal, the rotation direction of a spindle motor 6 is discriminated by the signal from an A/D converter 10, and the voltage of the opposite rotation direction is impressed for a prescribed time to brake the sindle motor 6. Thus, disk rotation is surely stopped though the read signal of the disk is not outputted from the pickup 5.

Title: Roll forming method for shaftlike metallic parts
Inventor: OGASA YOSUKE
IPC: B21H9/00
Filed: 1995-03-29
Abstract: PURPOSE: To produce rolled thread, which has less deformation through thread cutting with roll dies, by performing thread rolling on the outer diameter of a base material machined slightly smaller in the outer diameter in the center of a shaftlike metallic part than that of both ends before roll forming. CONSTITUTION: A shaftlike metallic part, i.e., round bar like object 3 to be worked is held in roll dies consisting of a fixed die 6 and a movable die 7, so that threading is performed on the outer diameter of the object 3 by operating roll dies. Before this threading, the size of the outer diameter D1 in the center 10 of those 11, 10, 12 of the object 3 to be threaded is formed with a reduced size slightly smaller than the outer diameter D2 of both ends 11, 12, 13. The reason is that the diameter is reduced in the equivalent to an excess thickness produced at the time of thread rolling of the object 3 by the roll dies, so that uneven thickness and pressure are absorbed which are due to plastic deformation caused by roll forming and that the deformation of the object is minimized.

Abstract: PURPOSE:To enable to perform an accurate self-correction in a short time, by a method wherein an intermediate frequency amplifier is gradually increased in gain by means of an output of a counter, and when a detection output exceeds a reference level, a counter is caused to stop counting. CONSTITUTION:In the case of correction, an output of a reference oscillator 2 matching a frequency of an electromagnetic wave to be measured is inputted to an intermediate frequency amplifier 7 through a switch 3, a frequency converter 4, and a variable high-frequency attenuator 6. Meanwhile, an output of a monostable multivibrator 18 resets a counter 14, and also sets a flip flop 16. This opens a gate 13, and a clock pulse from a generator 14 is counted by a counter 14. The output of the counter 14 is inputted to an amplifier 7 through a D/A converter 15 and a sensitivity adjuster 9, and when an output of a detector 8 increases to attain a voltage being equal to a reference voltage 11, a signal of an over range is generated from an A/D converter, and the flip flop 16 is reset to calibrate sensitivity.

Title: Acceleration sensor
Inventor: IWASAKI YUKIO
IPC: G01P15/12
Filed: 1991-04-25
Abstract: PURPOSE:To achieve easy production, facilitate the securing of accuracy, and expand the measurable area to the maximum extent. CONSTITUTION:A sensor chip 1 empoying a semiconductor substrate is provided with a cantilever 10 and a peripheral thick part 6 surrounding the cantilever 10 and the peripheral thick part 6 has a stopper action to stop the action of the cantilever 10 when a vibration works on the cantilever 10 exceeding a measuring range. The stopper action is achieved by a gap 5a between a central thick part 7 and the peripheral thick part composing the cantilever 10 or protrusions 9 or 9a sticking into a piercing part 5 from the peripheral thick part 6 or the central thick part 7. With acceleration within the measuring range, the cantilever 10 vibrates at an amplitude corresponding to the acceleration without contacting the peripheral thick part 6. But when excessive acceleration is applied, the cantilever 10 oscillates at a large amplitude but the amplitude exceeding a specified value is checked with a stopper thereby preventing destruction.

Abstract: PURPOSE: To use excess heat of a flue gas not required for operating a flue gas desulfurization apparatus by dividing an air preheater into two air preheaters while a partial stream of a flue gas is guided through the air preheaters. CONSTITUTION: An air preheater is divided into two air preheaters 3 and 4 to which preheaters 3 and 4 are attached bypass conduits 11 and 12.

Title: Transistor amplifier
Inventor: HORIGUCHI YUTAKA
IPC: H03F3/19
Filed: 1980-07-12
Abstract: PURPOSE: To decrease the capacity of emitter biasing power, by by-passing the emitter current on and after the emitter potential of a base common high frequency transistor (TR) is inverted to an opposite potential to the base potential, with the 2nd transistor.  
     CONSTITUTION: If a high frequency input is less, since the collector voltage of a TR13 is in an opposite potential, no current flows to the TR13. On the other hand, when the high freuquency input increases, the emitter current of a TR1 is increased, the emitter voltage VE at point A close to zero from a negative potential through the voltage drop across a resistor 8 and is inverted to a positive potential. After that, the emitter current further increased is by-passed through the TR13. This current does not become a load for an emitter bias power supply 12. The power supply 12 can be reduced for the capacity for the power loss' share, allowing to increase the overall efficiency of the amplifier.

Abstract: PURPOSE:To improve the durability against repeated-use of a joint pipe and enhance the stability when it is in use, by a method wherein a power supply connector is provided with a tubular member which is fitted on the circumference of a pipe main body and a cover. CONSTITUTION:A tubular member 61 is solidly fitted on the circumference of a pipe main body 26 and a cover 27 by adhesive or screws so as to cover a grip pie 14 of a hose 11 as a connecting pipe, and a power supply connector 21 for two extension pipes 17. On the other hand, at a power receiving connector 22 for the extension pipes 17 and a swivel pipe 7, a flange 63 is formed in a piece around the circumference of the pipe main body 26 and the cover 27. A load is exerted on the connectors 21 and 22 during cleaning. The load causes the pipe main body 26 to be pushed and expanded especially at the power supply connector 21 where an insert pipe 46 is inserted into a mouth pipe 36. Therefore, the load tends to pull the joint faces 26a and 27a of the pipe main body 26 and the cover 27 apart. However, as the main pipe body 26 and the cover 27 are held tight by the tubular member 26 of a molded piece, the power supply connector 21 is enhanced in strength.

Abstract: PURPOSE:To improve an output of an engine and facilitate setting of intake, exhaust, and ignition systems by setting axes of cylinders of the engine on a portion separated from an axis of each intake passage by 90 degrees around an crank shaft. CONSTITUTION:Aces C1, C2 of cylinders 11, 12 are located on portions separated from an axis C of an intake passage 16 to a crank chamber 15 by 90 degrees or more, so that the flow of intake gas A from the intake passage 16 to a skirt 32 of a piston 31 does not curve so much in each of the cylinders 11, 12. The intake gas A thus flows smoothly. In the cylinders 11, 12, a lever 33 hardly disturbs the flow of the intake gas A in an intake process wherein a large end 29 of a connecting rod 22 is located in ranges indicated by arrows E1, E2, so that the intake A flows smoothly. Outputs of both cylinders 11, 12 are substantially the same, and thereby setting of an intake system such as a cabureter 18, exhaust system, and an ignition system need not be changed between both the cylinders 11, 12.
