Title: Switching power device
Inventor: KAWABUCHI SEIJI
IPC: H02M3/28
Filed: 1987-07-07
Abstract: PURPOSE:To effect protecting operation stably, by a method wherein a voltage at the connecting point of a primary winding and a switching element is taken out through a capacitor to stop the driving of the switching element when an overvoltage is detected. CONSTITUTION:A switching transistor (Tr) 3 is connected to a power source input terminal 1, on which a DC voltage VIN is impressed, through the primary winding 2p of a power source transformer 2 while the transistor 3 is driven by a pulse, whose width is modulated by a driving circuit 11. A DC voltage VOUT is outputted from the secondary winding 2s of the transformer 2 through a rectifying diode 6 and the like. The voltage VOUT is inputted into the driving circuit 11 through an error amplifier 12, a photocoupler 15 and a comparator 20. In this case, an overvoltage detecting circuit 30 is connected to the connecting point A of the primary winding 2p of the transformer 2 and the transistor 3 through a capacitor 29 to control the operation of a switching circuit 22. According to this method, a tertiary winding for detecting an overvoltage becomes unnecessary and the overvoltage may be detected at the primary side of the transformer 2.

Title: Measuring device for distribution of illuminance
Inventor: SUZUKI KAZUAKI
IPC: H01L21/027
Filed: 1987-07-09
Abstract: PURPOSE:To enable the measurement of illuminance uniformity by a method wherein the number of pulses used as a measuring unit is calculated on the basis of an information corresponding to calculated nonuniformity and to an illuminance uniformity standard value set beforehand, and the number thus calculated is averaged. CONSTITUTION:Laser emission of a plurality of pulses is conducted, photoelectric conversion is conducted by an illuminance detector 34, and a photoelectric signal of each pulse is outputted to a first arithmetic means 40. The first arith metic means 40 calculates the nonuniformity in an energy amount of each pulse from the photoelectric signal of each pulse and outputs same to a second arith metic means 42. The second arithmetic means 42 compares the signal relating to the nonuniformity with the allowance limit to the nonuniformity set before hand and determines the number of integrated pulses at the time when illuminance uniformity is measured. According to this method, the illuminance uniformity can be measured even when irradiation is made by an energy generat ing source of a pulse generation type which has the nonuniformity in the energy amount for each pulse.

Title: Ultrasonic welding device and welding method
Inventor: FUJII ATSUHIKO
IPC: H01R43/02
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To obtain a stable, firm and lasting characteristic without any deviation among welding points in the case of collectively and simultaneously welding one side of material to be welded having plural branches and having a decided welding point on each branch, together with the other side of material to be welded. SOLUTION: At the time of welding, positions 5 having equal distance from the tip part 3 of each band material 2 is pushed and fixed with a pushing jig 6 other than the pressure by a welding head. In this way, ultrasonic wave is not transferred from the position 5 fixing the material 10 to be welded to the side where the welding head does not exist, and the vibration is not developed. Further, since the sides parted with a pushing jig 6 where the welding points 4 exist (the sides abutted on the welding head), have mutually equal surface area and therefore, equal in volume, the vibrating energy of the ultrasonic wave transferred to each of these parts is mutually equalized.

Title: Magnetic head and magnetic storage
Inventor: HORIGUCHI YASUYUKI
IPC: G11B21/21
Filed: 1997-06-26
Abstract: PROBLEM TO BE SOLVED: To enable contact start stop(CSS) activation only by a rotational force of a spindle on a smooth magnetic disk by providing a plurality of fine protrusions at the distal end portion of a protrusion provided at least one of a flying rail surface and a recess surface of a slider of a magnetic head. SOLUTION: Three protrusions 3 are provided on the flying rail surface 1 of a slider, and fine protrusions are further formed at distal end portions of the protrusions 3 by using the texture of the distal end portions of the protrusions 3 that can be in contact with the surface of a magnetic disk. The slider of the magnetic head contacts the surface of the magnetic disk through the fine protrusions at the distal end portions of the protrusions 3. The contact area is the sum of the areas of distal end surfaces of the fine protrusions at the distal end portions of the protrusions 3, and therefore the contact area is reduced in comparison with a conventional technique. Since the contact area is thus small, a frictional force acting on the slider can be reduced and CSS activation can be carried out without particularly carrying out releasing of sticking.

Title: Magnetic tape taking-up method
Inventor: YAMAUCHI MASAYA
IPC: G11B23/113
Filed: 1992-06-05
Abstract: PURPOSE:To prevent a tape from the quality deterioration at the take-up time and to take-up the tape at a high speed with low tension by making the vicinity of velocity changing points at the positions of start and end of tape winding on a take-up velocity curve to the curved line state. CONSTITUTION:The tape take-up velocity curve is provided with a section T1 (t0-t1) for the accelerating region to continue the acceleration at a prescribed increase rate, a section T2 (t1-t2) for the region of velocity keeping the state that the maximum take-up velocity is attained, and a section T3 (t2-t3) for the velocity reduction region to reduce the velocity at the prescribed velocity reduction rate and to stop. Then, the velocity curve in the sections T1 and T3 is formed to the S-shape by making the velocity curve in the vicinity of each point between t0 and t3 to the curved line state. As the result, a rapid change of acceleration is eliminated on each point between t0 and t3, then a gentle sine wave curve is formed.

Title: Structure for wiring layer of semiconductor device and its manufacture
Inventor: FUJIYOSHI EIJI
IPC: H01L21/3205
Filed: 1995-06-13
Abstract: PURPOSE: To flatten a wiring layer forming surface by suppressing the increases of plug losses and trenches in a tungsten etching back process and barrier metal sticking layer removing process. CONSTITUTION: A silicon nitride layer 14 is formed as a stopper on an SiO2 film 12 which is formed as an interlayer insulating film. Because of the film 14, the formation of TiSiOx due to the oxidation of Ti can be prevented during the course of heat treatment. Therefore, it becomes unnecessary to raise the etching rate at the etching back time of tungsten and removing time of a barrier metal sticking layer. In addition, since the generation of O2 from the SiO2 film 12 is inhibited by the silicon nitride film 14 covering the film 12, the dissociation of a reactive gas is suppressed and the increases of plug losses and trenches can be suppressed.

IPC: H03F1/32
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To provide a frequency mixing system which has a wider dynamic range than the dynamic ranges of respective mixers constituting a device. SOLUTION: An input signal S is divided into two paths 12 and 14. In the path 12, the signal S is mixed with a local signal by a mixer 16 with its high level as it is and exists as S' + D signal including inter-modulation distortion D through the next stage filter 28. In the path 14, the signal S reaches a mixer 20 on a low level through an attenuator 18, mixed with the local signal and reaches a coupling device 42 as S' through a filter 30 and a delay circuit 36. Here, it is connected with the S' + D signal from a coupling device on the path 12 to eliminate what it is except the distortion component D. Output distortion D of the coupling device 42 is connected with the signal S' + D on the path 12 in a coupling device 48 through an adjusting device 44 and a proportional amplifier device 46 and the signal S' remains to be an output 21.  The adjusting device, proportional amplifier device, etc., of each circuit are adjusted so that the signal S' can effectively remain at the output 21.
