Title: Production of composite casting
Inventor: MORICHIKA TOSHIAKI
IPC: B22D19/16
Filed: 1983-08-24
Abstract: PURPOSE:To prevent nonuniformity in structure owing to collapse of carbide particles and to improve the yield of a composite casting by increasing the casting speed ratio of a molten metal and particles in the stage of starting casting of carbide particles so as to attain the range of a limited value. CONSTITUTION:The casting speed ratio R1 of a molten metal and particles at the beginning of starting casting of particles is generally adjusted to 0.3-1.0. On the other hand the casting speed ratio R2 at the end period of casting is so adjusted as to attain 1.3R1-3.0R1. The reason for limiting the value of the ratio R2 lies in that if said ratio is <1.3R1 there is no effect and that if said ratio exceeds 3.0R1 the casting is difficult. The change of the casting speed ratio with time from the start of casting until the end period may be continuous or intermittent.

Title: Safety device for pot type burner
Inventor: NAKAMURA KAZUHARU
IPC: F23N5/08
Filed: 1985-07-12
Abstract: PURPOSE:To detect the abnormality of combustion condition from the characteristics of the pot type burner by a method wherein a reversed pan type diffusion plate is attached to a pot, a multitude of small holes is provided on the side wall of the pot and a small number of small holes is scattered on the side wall of another pot to detect the combustion condition by the output signal of temperature detecting section of the reversed pan type diffusion plate. CONSTITUTION:The amount of air, supplied through the small holes 3' at the lower part of the pot 1, is reduced to restrict the amount of heat generation due to combustion in the pot 1, therefore, most of fuel, sent to the pot 1, escapes upwardly through a clearance between the reversed pan type diffusion plate 2 and the pot 1. On the other hand, the side wall of the pot at the side of the reversed pan type diffusion plate 2 is provided with a multitude of small holes 3 and much amount of air is supplied in concentrated condition, therefore, the combustion of combustible gas is progressed rapidly. The red-hot condition of the reversed pan type diffusion plate 2 upon normal combustion can be changed into the condition that it is not red-hot substantially upon abnormal combustion and a difference therebetween is large, therefore, the combustion condition may be detected by the output signal of the temperature detecting section 4 by the provision of the temperature detecting section 4 of the reversed pan type diffusion plate 2.

Title: Vertical magnetic recording head
Inventor: NISHIMURA MASARU
IPC: G11B5/187
Filed: 1987-06-22
Abstract: PURPOSE:To eliminate a need of a dedicated erasing circuit and to simplify a circuit without demagnetizing data tracks neither distorting a reproduced waveform by providing an auxiliary core with a second main magnetic pole. CONSTITUTION:When a high frequency recording data signal is allowed to flow to an exciting coil 10, a magnetic exciting core 11 is excited to form a magnetic path passing first and second main magnetic poles 8 and 9. Then, the data signal is recorded by rear edge parts of magnetic poles 8 and 9. Recorded data 13a and 13b have angles of inclination to each other, and the magnetic pole 8 reproduces data 13a by the azimuth effect at the time of reproducing. Meanwhile, the magnetic pole 9 cannot reproduce the high frequency signal because it is thicker. Therefore, data 13b is not reproduced through being recorded, and the same effect as AC erasing is attained to prevent an influence of crosstalk. Further, an erasing current is unnecessary to simplify the circuit.

Title: Method for measuring electric current of battery pack
Inventor: DOI SHUNICHIRO
IPC: H01M10/48
Filed: 1998-06-03
Abstract: PROBLEM TO BE SOLVED: To correct the drift of a current measuring unit caused by the secular change and the environmental temperature. SOLUTION: The current running in a resistor for measurement is converted into the voltage by an operational amplifier. A V-f converter generates the pulse of the frequency according to the output voltage of the operational amplifier. A counter counts the pulse only for a specified time. If the counted value is C, the formula to operate the current is expressed by I=(C-DOS)/DG. DOS is an offset correction value obtained in correcting the drift, and DG is a gain correction value. The counted values when the charging current of 0 mA and about 3000 mA actually runs in inspecting a substrate, and the counted values of the voltage corresponding to 0 mA and the voltage corresponding to 3000 mA are examined. The drift is corrected for each 30 seconds, and the counted values of the voltage corresponding to 0 mA and the voltage corresponding to 3000 mA are examined.  DOS and DG are obtained from these counted values. The formula to operate the current is updated by the new DOS and DG obtained for each 30 seconds, and the current is measured for each 220 ms.

Abstract: PURPOSE:To shorten an arithmetic period by dividing digital arithmetic processing necessary for servo head positioning into a part which requires high-speed arithmetic and a part which is performed sufficiently by low-speed processing, and putting different computing elements in charge of them. CONSTITUTION:Servo information recorded on a magnetic disk 12 is obtained as an analog position signal 14 through a servo head 9 and a demodulator 10 and the number of times of zero crossing of the position signal 14 is counted by a counter 13 to obtain the number of tracks that the servo head 9 moves over. Further, the position signal is passed through an A/D converter 11 to obtain the relative error from the center of a track as a digital value, and the output of a high-speed digital computing element 16 is inputted to a power amplifier 7 through a D/A converter 6 to drive an actuator 8. A timing computing element 15 performs timing control over the counter 13, A/D converter 11, D/A converter 6, and high-speed digital computing element 16 within one arithmetic period. The obtained error signal is inputted to the power amplifier 7 through the D/A converter 6 to drive the actuator 8, thereby positioning the servo head 9 properly. Consequently, the high-speed, high-precision magnetic head position control is performed.

Title: Manufacture of electro-optical device
Inventor: ARAKI RYOSUKE
IPC: G02F1/136
Filed: 1992-06-15
Abstract: PURPOSE:To obtain the electro-optical device whose contrast is satisfactory by forming a non-linear element by a second metallic layer structure formed on the side face of a first metallic layer-an insulating layer-a first metallic layer by a specific process, respectively. CONSTITUTION:A Cr film 16 is formed, subjected to patterning to a prescribed shape, and thereafter, a resist 21 whose viscosity is small is applied to the whole surface,. Since the viscosity is small, as for a recessed part on a substrate, resist film thickness is thick, and as for a projecting part, its thickness becomes thin. When the resist 21 of a substrate 11 to which the resist is applied is etched, the part whose resist film thickness is thin is eliminated and the film surface of the lower layer, that is, the Cr surface on Ta is exposed. When this exposed Cr surface is etched, a step difference part of the Ta film is not etched but left because it is thick in the vertical direction, and an electrode 22 of an MIM element is formed. Thereafter, a transparent electrode 19 is formed and an MIM element substrate is generated. In such a manner, the capacity of the MIM element becomes small, and a non-linear element whose capacity ratio is smaller than that of picture element electrode is obtained.

IPC: H01L33/60
Filed: 1981-09-30
Abstract: PURPOSE:To stop plating of silver for improving the bondability only to the necessary part by providing a metal container having a reflecting surface at one end of a conductive lead in the manufacture of an LED lamp, and arranging a photosemiconductor element in the container, thereby alleviating the restriction in the material of the reflecting surface and the pressing velocity, and reducing the deformation during handling. CONSTITUTION:Since a container 12 is constructed separately from a cathode lead 11 in an LED lamp, no restriction exists in the material of the lead 11 on the reflecting surface, but an aluminum foil having high reflectivity can be used. A recess is not necessary for the lead frame, but only a drawing step is required, and the pressing speed is accelerated by twice to three times of the conventional speed, and the deformation during the handling is extremely small. Further, since the difference between the ends of the lead 11 and the anode lead 16 is increased in the amount corresponding to the container 12 as compared with the conventional one, silver plating can be performed only on the bonding surface 16a to be originally necessary, thereby reducing the silver plating amount of approx. 1/3.

Filed: 1990-06-15
Abstract: PURPOSE:To hold an overcurrent protecting operation even if a semiconductor element in a circuit on the load side becomes unstable of a half short-circuit by disposing a current breaking circuit for breaking the output of a DC power source when the output exceeds a set value between the power source and a switch circuit. CONSTITUTION:Since a terminal voltage of a current detector 3 exceeds a saturated voltage between the base and the emitter of an NPN transistor 27 if continuing time of a short-circuit is long, the transistor 27 is conducted, and then a PNP transistor 28 is conducted. As a result, the gate voltage of a thyristor 30 is raised, and the thyristor 30 is conducted between an anode and a cathode. This state is equivalent to the short-circuit of both electrodes of a DC power source 5, and a current of a melting current value or higher flows to a fuse 31. Accordingly, the fuse 31 is melted to break the power source 5 itself. Even if a load current does not reach a current limiting value due to a half short-circuit, etc., of a load side, breaking circuits 29a, 29b are operated to break the power source 5.
