Title: Perpendicular magnetic recording medium
Inventor: KISHIGAMI JUNICHI
IPC: G11B5/738
Filed: 1989-03-29
Abstract: PURPOSE:To decrease the medium noises by a magnetic underlying film and to decrease the side strokes in a track direction as well by costituting the underlying film of low coercive force magnetic parts and low magnetic permeability parts which are alternately constituted to a concentrical shape. CONSTITUTION:The constitution of the magnetic underlying film 2 is alternately formed of the low magnetic permeability parts 5 and the low coercive force magnetic parts 4 on the concentrical circle. The width of the low coercive force magnetic parts 4 is made the same as the track width of the head to be used for recording and the value obtd. by adding the width of the low coercive force magnetic parts 4 and the width of the low magnetic permeability parts 5 is equalized to the track pitch of a magnetic disk device. Most of the magnetic fluxes emitted from the head on a perpendicularly magnetized film 3 having the low coercive force magnetic parts 4 on the rear side have the magnetic paths to close toward a rotating direction 100 but there are the low magnetic permeability parts 5 in a radial direction 102 and, therefore, the spread of the magnetic paths in the radial direction 102 is extremely smaller than in the rotating direction 100. The volume of a noise generating source is decreased by providing the low magnetic permeability parts 5. The medium noises and side crosstalks are decreased in this way and the track density is improved.

Title: Blower
Inventor: HAMA MAMORU
IPC: F04D29/66
Filed: 1984-04-18
Abstract: PURPOSE:To obtain a nearly constant discharge amount by setting the balance between each dimension of an axial-flow fan and a motor to the balance which forms an overload for the motor and installing a sound arrester for throttling a discharged wind amount at a discharge port, in an axial-flow type blower. CONSTITUTION:For a driving motor 14, a conventional fan 22 which forms an overload for the motor 14 is not used, but a large fan which is usually used for a 4-pole driving motor having the equal output to that of a 2-pole driving motor 14 is used, and the dimension of the fan is set to form an overload for the motor. Further, a sound arrestor 40 is installed so that the wind amount at a discharge port 30 is throttled.

Title: Chrominance signal reproduction processing circuit
Inventor: HAGIWARA AKIHITO
IPC: H04N9/79
Filed: 1987-03-31
Abstract: PURPOSE:To reduce the numbers of external circuits and pins of an IC circuit and to stabilize the operation by providing two sampling hol circuits which are alternately subjected to sample-and-hold of a reproduced line-sequence color difference signal at every 2H and a voltage comparator which compares output voltages of these circuits with each other. CONSTITUTION:Two sampling hold circuits 61 and 62 which are alternately subjected to sample-and-hole of the signal at every 2H and a voltage comparator 7 which compares voltages of outputs (f) and (g) of circuits 61 and 62 with each other are provided. Consequently, only the DC potential difference at every 1H is detected independently of the variance of DC potential due to the difference of the color difference signal. Therefore, the capacity for elimination of DC variance is unnecessary, and an HPF is unnecessary because edge detection is no performed. Thus, the numbers of external circuits and pints of the IC circuit are reduced and the influence of noise is reduced to stabilize the operation.

Title: Exhaust gas purifier for diesel engine
Inventor: SUZUKI YOSHINOBU
IPC: F23J15/00
Filed: 1978-06-27
Abstract: PURPOSE: To purify the exhaust gas of a Diesel engine in its test running, by surely removing black smoke particles with a heat-resisting filter and removing smells and harmful gases with a catalytic converter.  
     CONSTITUTION: In the test running, only a damper 4 and a valve 13 are opened but other dampers and valves are closed so that the exhaust gas is preheated by a heater 7, passed through the heat-resisting filter 6 and the catalytic converter 15 and discharged from a chimney. Because the temperature of the exhaust gas is raised by the heater, the activity of a catalyst 16 is increased to thoroughly remove the harmful gases. Since the black smoke particles in the exhaust gas are thoroughly removed by the heat-resisting filter, no black smoke particles adhere to the catalyst and reduce its function.
