Title: Magnetic head
Inventor: YODA HIROSHI
IPC: G11B5/127
Filed: 1988-03-15
Abstract: PURPOSE:To easily obtain a magnetic head which is capable of sufficiently exhibiting the outstanding characteristics thereof even if a system in which two pieces of heads are disposed at a narrow gap spacing by forming a magnetic metallic material on the end face of an I-shaped core opposite to the winding window thereof. CONSTITUTION:A magnetic metallic film 1 consisting of an amorphous alloy or 'SENDUST(R)', etc., is sandwiched by a nonmagnetic substrate 2 consisting of ceramics of a calcium titanate system, etc., to constitute a main magnetic core. The magnetic core consists of a C-shaped core having a winding window 3 and the I-shaped core about 0.2mm length in the traveling direction of a recording medium. These cores are joined by bonding glass 4 via a nonmagnetic film to form the magnetic gap 5. The magnetic metallic film 6 is formed via a nonmagnetic insulating film on the side face of the I-shaped core on the side opposite to the winding window thereof. The magnetic metallic material 6 formed in the end part is thereby added in parallel to the magnetic path even if the length L of the I-shaped core is short and, therefore, the magnetic resistance of the I-shaped core part is lowered and the degradation in reproduction efficiency is prevented. The magnetic head capable of recording and reproducing signals with high efficiency is thus obtd.

Title: Write high-tension supply circuit
Inventor: NABEYA SHINJI
IPC: G11C11/34
Filed: 1978-05-24
Abstract: PURPOSE:To realize the read operation of a nonvolatile semiconductor memory with a high write voltage applied, by applying the high write voltage to the output of an address decoder output circuit via a depletion MISFET. CONSTITUTION:During write operation, a fixed high voltage is applied to write voltage terminal Vpp, write information is supplied to input terminal I/O, and a H-level pulse signal prescribing the write time is inputted to operation mode terminal PD/PGM. Once the high voltage is applied to the output of X-address decoder circuit 3 via high-tension supply circuit 8 while this pulse signal is applied, MISFETQ27 becomes high in voltage level to develop a selective high-level voltage at word line W1. In Y-address circuit 4, digit line D1 is similarly made high in voltage level and writing to memory Qc3 is performed. Since terminal PD/PGM is at level L, the output of inverter 1N4 becomes level H to turn FETQ33 ON and the information of memory Qc3 is read out from terminal I/O via amplifier 5, so that while the high write voltage is applied, information will be read out.

Title: Feeding and exhausting device of air
Inventor: KAWASAKI HIROSHI
IPC: F23L17/04
Filed: 1982-04-13
Abstract: PURPOSE:To miniaturize a device and to improve weather resistances without damaging feeding and exhausting performance, by a method wherein a device being excellent in a feeding and exhausting efficiency is mounted at the upper part of a combustion device. CONSTITUTION:A panel 9 for preventing the intrusion of rainwater having a height l sufficient to prevent the intrusion of rainwater through an exhaust port 7 is secured to an outer periphery of an exhaust tube 6. The length of the outer periphery of an exhaust tube 6 multiplied by l1 makes an area at the exhaust tube 6 of an exhaust path, and the length of the outer periphery of the panel 9 multiplied by l2 makes the area at the panel 9 for preventing the intrusion of rainwater. The installation of the panel 9 to the outer periphery of the exhaust tube 6 causes the panel 9 to have the length of the outer periphery being longer than that of the exhaust tube 6, and this establishes a relation of >1>l2. This permits reducing of the height by positioning a feed port in the vicinity of the exhaust port, allows the efficient arrangement of a device even at a limited space, and besides, prevents deteriorating of a combustion condition even if a strong wind is blown thereagainst.

Title: Frame synchronizing circuit and frame timing extracting method
Inventor: FUKAWA KAZUHIKO
IPC: H04B7/26
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To obtain a frame synchronizing circuit satisfactorily operating even under a multipath propagating situation where the same chanel interference cannot be neglected and to obtain a frame timing extracting method. SOLUTION: A received signal memory 51 stores one frame of received base band signals from antennas 111 to 11k and outputs the received base band signals twice for each section of each virtual frame synchronizing signal. A parameter estimating circuit 58 sets the weighting coefficient of a linear composer 61 so as to minimize the average square of a differential signal based on a first received base band signal output and a frame synchronizing signal. The composer 61 multiplies a second received base band signal by complex multipliers 521 to 52k and adds them by a complex adder 53 to output a composed signal y(i).  A frame timing detector 55 investigates the differential signal e(i) of all the virtual frame synchronizing signal sections with the difference between the signal y(i) and the frame synchronizing signal as the differential signal and outputs the virtual frame timing of the smallest difference as an optimum frame timing.

Abstract: PURPOSE:To make it possible to reduce the generation of chip cracking in a semiconductor element to a large extent, by performing machining for increasing the bonding strength with a sealing resin at a part lower than a semiconductor-element attaching part of a heat radiating plate. CONSTITUTION:A semiconductor element 1 is attached to a heat radiating plate 2 comprising Cu metal. A machined part, e.g., a groove X, for increasing the bonding strength with a resin 5 is provided at a part lower than the attaching part of the element 1 in the heat radiating plate 2. Even if forces shown by arrows Y1 and Y2, which are yielded by the deviation of a part Z for fixing a lead part 3 of a substrate 6, are applied on the semiconductor device, separation of the heat radiating plate 2 and the resin 5 can be prevented. Because the groove X is formed at a part lower than the attaching part of the heat radiating plate 2 and the resin 5, and the bonding strength of the heat radiating plate 2 and the resin in this vicinity is improved. Thus, the problem of chip cracks in the semiconductor element 1 is improved.

Filed: 1985-03-28
Abstract: PURPOSE:To manufacture a multilayer thin film structure such as superlattice rapidly in large quantities, by providing a substrate rotating means, and by arranging each means for forming two or more kinds of thin film layers in order not to be interfered with each other, along the substrate rotating locus. CONSTITUTION:An endless flexible substrate 2 is stretched around rollers 3, 3' and is set by regulating tension rollers 8, 8'. Next, The reaction chamber 1 is exhausted to 10<-7> Torr and the flexible substrate 2 is cleaned by cleaning light sources 5, 5'. After each reactive gas is introduced into the reaction chamber 1 from nozzles 6, 6' by given flow rates, each light emitted from light sources 4, 4' produces a photo chemical reaction to deposite different kinds of thin films on the flexible substrate 5. At this time, moving the flexible substrate 2 at a proper speed can attain desired film thickness. Thereafter, since the section having the thin film formed is moved by rotating the rollers, different kinds of thin films are deposited thereon in the same way after the cleaning light sources 5, 5' clean the substrate 2.

Title: Surface acoustic wave device
Inventor: YOSHIMOTO SUSUMU
IPC: H03H9/25
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To improve the degree of freedom for design suppressing a lateral second-order spurious mode in spite of the electric/mechanical coupling coefficient of a substrate by setting the ratio between the crossing width and opening length of interdigital type electrodes within a specified range. SOLUTION: A resonator type surface acoustic wave(SAW) filter is constituted by forming interdigital type electrodes 2 and 3 composed of metal thin films on the main surface of a piezoelectric substrate 1 composed of crystal. When an AC voltage is impressed to the interdigital type electrodes 2 and 3, a SAW to be propagated vertically to the interdigital pieces is excited on the surface of the piezoelectric substrate 1 by piezoelectric operations. Grating reflectors 4 and 5 reflect the SAW inside and confines the energy of the SAW inside. In this case, the ratio of crossing width W to opening length Wo of the interdigital type electrodes 2 and 3 is set within the range of (W/Wo)=(0.75-0.85). Although both positive and negative areas exise in distribution 22 of the lateral secondary mode, since the W/Wo is set like this, both the positive and negative areas can be canceled.
