IPC: G11B11/10
Filed: 1987-03-31
Abstract: PURPOSE:To decrease the leakage magnetic field of a magnetic field radiating part, to improve the magnetism utilizing efficiency and to reduce the power consumption by forming a cross section of a magnetic flux radiation part to be a wedge shape whose cross section is decreased along the major axis from the coupling part with a magnetic core part. CONSTITUTION:Magnetic flux leadout part 37 is formed to be a wedge shape in a way that the thickness is decreased along the major axis from the center being the coupling part of the magnetic core part 34 toward the tip and has a length corresponding nearly to the radius of an optical disk 20. That is, the magnetic flux radiating face 37A is prolonged at the outside of the range corresponding to the region on a magneto-optical recording film 24 capable of being radiated with a light beam focused by an objective lens 25 and the magnetic flux radiating face 37A being a flat lower face at the recording or erasure of information is opposed to the light beam radiation enable region of the magneto-optical recording film 24. Since the cross section of the magnetic flux radiating part 37 is formed to be a wedge shape in a way that the thickness is decreased along the major axis from the coupling part with the magnetic core 34, the magnetic field leaked to the magnetic flux radiating part 37 is small, the magnetism utilizing efficiency is improved and the power consumption is made small.

Title: Waveform equalizing device for teletext
Inventor: YAMAUCHI KAZUHIKO
IPC: H04N7/03
Filed: 1988-03-31
Abstract: PURPOSE:To attain normal waveform equalization when a ghost is returned to a normal ghost by deciding whether a framing code(FC) is detected from a waveform equalization output at the multiplex line of a character multiplexing signal or not when the number of the times of correcting a tap gain reaches the prescribed number of times and setting the value of the tap gain to an initial value when the FC is not detected. CONSTITUTION:An FC detecting circuit 40 detects the FC from the output of a binarizing circuit 33 at a line on which the character multiplexing signal is superimposed. This detected output is supplied to a CPU 41, and the CPU 41 decides whether the FC is detected or not when the number of time of correcting the tap gain reaches the prescribed number of times, sets the value of the tap gain to the initial value when the FC is not detected, and decides whether the FC is detected every time or not while correcting the tap gain when the FC is detected. Thus, the divergence of the tap gain due to a ghost fluctuation can be prevented, and a normal waveform equalizing operation can be executed when the ghost fluctuation is eliminated.

Title: Pasted positive electrode for lead storage battery
Inventor: HOSHIHARA NAOTO
IPC: H01M4/14
Filed: 1982-05-10
Abstract: PURPOSE:To obtain a lead storage battery having an excellent life characteristic by providing a layer, which contains a large quantity of a peroxide of lead such as PbO2 or Pb3O4 which is chemically manufactured, near the surface of an unformed pasted positive electrode plate. CONSTITUTION:A plate for a lead sotrage battery is made by applying a paste prepared from lead powder, which is used as an active material, to a supporting member, and then either coating thus obtained member with a paste prepared from chemically manufactured PbO2 or fixing a slurry prepared from chemically manufactured PbO2 on thus obtained member. When such a plate having a relatively inactive PbO2 layer is used, active PbO2 contained in the inner part of the plate preferentially undergoes reaction, and only a small proportion of the surface layer of the plate undergoes reaction. As a result, the size of the active material contained in the surface is not decreased almost entirely, and separation of the active material hardly occurs in the plate. Besides, even if the size of the active material contained in the inner part of the plate becomes very small, separation of the active material is suppressed by the active material contained in the surface layer. In addition, PbO2 which has not undergone any reaction remains in the surface of the plate even after the end of elctric discharge, aiding charging which proceeds from the surface. Here, Pb3O4 may be used instead of PbO2.

Title: Exposure and aligner for semiconductor
Inventor: HARADA HIROYOSHI
IPC: H01L21/027
Filed: 1993-04-06
Abstract: PURPOSE:To prevent the cracking of wafers and improve the working efficiency and yield by attracting a semiconductor substrate by vacuum suction while the entire surface of an exposure stage is covered with a resin sheet and exposing the substrate by removing the sheet after suction. CONSTITUTION:When vacuum suction of a wafer 1 having an convex surface on the upper side is started in a state where the entire surface of an exposure state 3 is covered with a resin sheet 2, the vacuum suction of the wafer 1 is hindered when the part of the sheet 2 outside the outer periphery of the wafer l is strongly attracted even when the space between the wafer 1 and stage 3 is uniformly evacuated through vents uniformly distributed throughout the stage 3. Therefore, the central part of the wafer 1 is first attracted, because the central part of the wafer 1 is strongly evacuated through the vents at the central part of the stage 3 in the first stage and the sheet 2 at the peripheral part is first attracted so that the sheet 2 can slip on the stage 3 in accordance with the extent of the wafer 1. After the whole body of the wafer 1 is sufficiently attracted to the stage 3, the sheet 2 is removed and the wafer is exposed.

Title: Ultrasonic diagnostic apparatus
Inventor: TAKEUCHI YASUTO
IPC: G01N29/44
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To provide an ultrasonic diagnostic apparatus capable of processing images on the basis of a small data quantity. SOLUTION: The interior of a subject is scanned with an ultrasonic beam to obtain sound ray data of a large number of sound rays to store the same in a sound ray memory 4. Next, an image formed by a large number of sound ray data is analyzed in an image analyzing part to extract image elements. The image elements are combined in an image compositing part 6 to composite a display image to display the same on a CRT 8. The preservation of the image in an image preserving part 9 is performed by gathering image elements. The transmission and reception of the image in an image transmission part 10 is performed by gathering the image elements. Therefore, since the image is processed by the gathering of the image elements without processing the image by the gathering of B-mode sound ray data, data quantity becomes small and processing load can be reduced.

Title: Drive circuit device for motor
Inventor: KISHIMOTO TADAO
IPC: H02P29/00
Filed: 1984-04-20
Abstract: PURPOSE:To accurately control the rotating speed of a motor by using a constant frequency oscillator and a counter for a frequency/voltage converter, thereby allowing a DC signal accurately corresponding to the rotating speed of the motor to always become a feedback signal irrespective of the variation in the temperature or the lapse of the time. CONSTITUTION:A frequency proportional to the rotating speed of a DC motor M3 is produced from a frequency generator 18, it is shaped in the prescribed pulse waveform by a waveform shaper 19, and input to a F/V converter 8. The converter 8 measures the oscillating frequency of a constant frequency oscillator 20 by a counter 14 and converts a signal from rotating speed detecting means into a DC signal. Thus, a DC signal accurately corresponding to the rotating speed of the motor always becomes a speed feedback signal irrespectively of the variation in the temperature or the lapse of the time, thereby accurately controlling the rotating speed of the motor.

Title: Cooling device
Inventor: NAGATAKE MASAHIKO
IPC: F25B1/00
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent a compressor from being damaged even when a refrigerant leaks from a refrigerant circuit by stopping the compressor when a pressure switch that operates at a specific low pressure and mounted to the high-pressure pipe of the refrigerant circuit operates. SOLUTION: When a refrigerant gas in a refrigerant circuit 1A leaks due to, crack or welding failure of pipes 2A, 3A, 5A, 6A, and 12A, an the like during the cooling operation of a cooling device 1, a refrigerant pressure at the high- pressure side of a refrigerant circuit 1A decreases, when a pressure in the pipe 3A at a high-pressure side decreases, the decrease is detected and a pressure switch 8 is opened, thus prohibiting the conduction to a coil. As a result, a magnet switch is turned off for stopping a driving motor and a compressor 2 stops operating, thus stopping the cooling operation of the cooling device 1.  In this manner, when gas refrigerant in the refrigerating device 1A leaks due to some causes, the pressure switch 8 provided at the high-pressure side of the refrigerant circuit 1A opens, and the driving motor is stopped and hence the operation of the compressor 2 can be stopped.
