Title: Semiconductor device
Inventor: TOMITA YUTAKA
IPC: H01L29/04
Filed: 1981-02-24
Abstract: PURPOSE:To minimize property fluctuations in building a planar type N-P-N transistor on a substrate with a crystal orientation virtually parallel with a plane (111) by a method wherein an expression a <3XJ holds between the emitter/base junction depth Xj and the emitter longer dimension size (a). CONSTITUTION:Formed on a plane (111) or on a P type semiconductor substrate 8 with a crystal orientation virtually parallel with a plane (111), is an N-P-N transistor region consisting of an N<+> type emitter region 3, P type base region 4, N type collector region 5, imbedded N<+> region 6, and a P type insulator diffused region 7. Here, the emitter/base junction depth Xj and the emitter longer dimension size (a) are to be determined so that they may satisfy an expression a <3Xj. In a photoetching tenchnique, a 2Xj can be obtained using an oridinary diffusion method and, using the ion implantation, something near a Xj can be obtained. By this, external stress caused fluctuations in the current amplification factor beta can be kept low.

Title: Display device
Inventor: KANI AKIRA
IPC: G09G3/28
Filed: 1993-01-22
Abstract: PURPOSE:To provide a display device having small power consumption by providing one or more display anodes for a pair of a cathode and an auxiliary anode, and providing the means for cathode temperature rise, auxiliary discharge generation, heating cutoff, operating temperature maintenance, and display anode drive. CONSTITUTION:When an exciting switch S is closed, a cathode filament is excited and heated by a power source 1 to the preset temperature. When the voltage of a power source V2 is kept at the discharge start voltage or above for a cathode, an arc luminescent spot is generated on the filament, and an auxiliary discharge occurs. The switch S is opened to save the cathode heating power immediately after the auxiliary discharge occurs. If the preset power is fed to V2, the auxiliary discharge is maintained, and part of the cathode is kept at the operating temperature during the display period thereafter. The voltage signal generated from the limiting resistor of an auxiliary discharge circuit is utilized to open the switch S, and switching is performed via a transistor.

Filed: 1987-02-06
Abstract: PURPOSE:To satisfy the requirements to a head driver and at the same time to simplify the working structure of the head driver, by using the 1st and 2nd plate springs. CONSTITUTION:A groove 11d is formed mechanically at the position where a circular sleeve 19 is opened toward a hole to which the annular sleeve 19 is fitted slidably within a lower actuator housing part 11b. Then a leaf spring 14 is pushed into the groove 11d. A bend part 14b is provided to increase the angle at which the spring 14 touches a part close to the bottom of the groove 11d. Thus the form of the bearing point of the part 14b is decided more clearly. The annular sleeve 19 is fitted into a hole of the part 11b with a slight tolerance. Therefore the power needed to apply the lateral load force to a desired lower bearing structure 17 can be minimized. Then the spring 14 is set at a proper position to the sleeve 19. A bowl-shaped circular spring 20 or a bow- shaped plate spring is used to produce the load of axial direction that ensures the axial rigidity.

Filed: 1982-02-22
Abstract: PURPOSE:To obtain an intense swirl air flow by a construction wherein an air flow guide wall is formed in the peripheries of an air inlet value a stem  and a valve stem guide so as to extend from the upper surface of a spiral passage thereby preventing the swirl flow caused by the spiral passage from being caught around the air intake valve stem or the valve stem guide. CONSTITUTION:The helical port is defined by a spiral passage 20 formed in the terminal end of an air inlet passage 18. The air introduced into a cylinder 10 is given a swirl motion by the passage 20. In the peripheries of an air inlet valve stem 14 and a valve stem guide 16, a circumferential wall 26 extends downwardly from the upper surface 24 of the passage 20. The circumferential wall 26 extends gradually downwards from QL line so that it becomes largest near QI and QH lines and smaller as it approaches QA line, and zero at QA line, Further, the circumferential wall 26 is formed in the angular range of 270 deg. in the periphery of the valve stem 14, whilst a partition wall 28 is formed in the range of the remaining 90 deg.. This arrangement enables the air drawn into the cylinder to be guided by the circumferential wall 26 and prevents the air from being dragged around the valve stem 14 and the valve stem guide 16.

Title: Method for recording magnetic head position measuring signal
Inventor: ADACHI NOBUYUKI
IPC: G11B5/56
Filed: 1987-02-09
Abstract: PURPOSE:To prevent a peak value from being projected and to accurately measure the azimuth of a magnetic head by setting up the initial and final half periods of recording to a value shorter than an average half period in the case of recording an azimuth burst signal in an alignment disk. CONSTITUTION:In the case of measuring the azimuth of a magnetic head 1, a burst signal recorded in an alignment disk is read out by the head 1 and detected by a detecting circuit consisting of a reproducing amplifier 2, a diode 3 and a buffer 6 to find out an envelope of a signal waveform. Plural envelopes for the inclination of a head gap are found out and the azimuth is found out from their amplitude ratio. When the burst-like signal is read out by the head 1, peak values in the initial and final half periods are generally high and accurate envelopes can not be obtained. Thereby, the half periods of the initial and final signals are set up to a value shorter than the average half period in the case of recording a burst signal in a disk to prevent the generation of a peak.

Abstract: PURPOSE:To prevent abrupt change of the engine output and contamination of ignition plugs of a two-point ignition engine having two ignition plugs the electric circuits of which are independent from each other, by delaying the ignition timing of one of the two ignition plugs substantially in proportion to the engine output. CONSTITUTION:Ignition triggering signals from pickups 17A, 17B adapted for detecting the position of a rotor 18 of a distributor 19 are given to power transistor circuits 14A, 14B. Here, there is provided a delay circuit 15 for delaying the signal from one pickup 17A in proportion to the increase in the output of engine afforded from a load detecting circuit 16. A VC negative pressure corresponding to the engine load is transmitted to a diaphragm means 23 for turning a pickup plate 22 in response to the VC negative pressure. That is, the ignition timing is advanced with increasing of the rotational angle of the plate 22. On the other hand, the output of the load detecting circuit 16 is changed with rotation of the plate 22, that is, the output is increased with increasing of the load. On the basis of the load output, the delay circuit 15 produces a delaying quantity proportional to the input, delays the input pulses and hence the ignition timing of line A.
