Title: Playing method for digital audio tape recorder
Inventor: KANDA HIDEAKI
IPC: G11B27/28
Filed: 1989-02-01
Abstract: PURPOSE:To avoid the omission of the head of a desired program music with no output of the head of the next music by preparing a recording/reproducing circuit, a signal processing part, a delay circuit, a system controller, and an acoustic circuit. CONSTITUTION:A signal processing part 13 separates a subcode including a start ID and the voice data AS from the digital data supplied from a recording/ reproducing circuit 11 and outputs these subcode and data. A delay circuit 15 delays the data AS by a prescribed time and inputs it to an acoustic circuit 19. At the same time, a system controller 17 decides the end of music with detection of the start ID and to start the search of the next program music in a mute state. Therefore the head of the next music is never outputted even in the case the start ID is recorded with a delay at the music head. The reproduction of the next program music is started earlier than the start ID by a prescribed time, and the mute state is cancelled when the start ID is detected. Thus the next program music is outputted with no omission of its head.

Title: Autowiper device
Inventor: FUJIMURA KEIJI
IPC: B60S1/08
Filed: 1983-02-15
Abstract: PURPOSE:To prevent operation of a wiper at the time of car washing due to forgetting to turn off a wiper switch by controlling operation of a wiper driving circuit by means of logical sum of a pulse of the constant width from a timing pulse and a signal of waterdrop detection from a waterdrop detector. CONSTITUTION:When an autowiper switch 1 is placed in ON state, a pulse (b) of the constant width T1 is produced from a timing pulse generator 3, while a signal C of waterdrop detection corresponding to a condition of attachment of waterdrops to a window shield is sent out from a waterdrop detector 4. OR gate 5 takes logical sum of both signals (b), (c) and starts, by its output (d), a one shot.multivibrator OSM6, which sends out a pulse (e) of the constant width T2 to put a wiper driving circuit 7 in operation, and a wiper motor 8 is rotated. When the rain is over, since the wiper makes an intermittent action by the constant width T1 of the pulse (b) from the pulse generator 3, an operator puts the switch 1, as unnecessary, in OFF state. Thus, forgetting to turn off the wiper switch 1 can be prevented.

Title: Production of magnetic head
Inventor: MIYAZAKI MASAHIRO
IPC: G11B5/10
Filed: 1983-02-14
Abstract: PURPOSE:To obtain a magnetic head which can coat properly the lubricant to a recording disk and absorb the lubricant by roughing the rail surface of a slider substrate with use of metallic crystal grains as a mask. CONSTITUTION:A metallic film of Al, etc. is vapor deposited on the rail surface of the projected ferrite of a slider substrate 1 which holds a magnetic head to form a aggregate of crystal garins 2. Then a plasma etching process is applied to the substrate with the prescribed reaction gas. Thus the grain boundary part of the grain 2 is etched to be changed into a crystal grain 2A. This grain 2A is used as a mask to etch the ferrite forming the rail surface by means of the prescribed reaction gas in order to eliminate the grain 2A. Thus a rough surface containing recess parts 3 is obtained for a head. Then a liquid lubricant 5 is filled into the recess 3. A proper amount of lubricant 5 is coated to a disk after the disk is heated by an air current produced by the high-speed revolutions of the disk. Then the lubricant 5 is absorbed into the recess 3 by the surface tension when the revolution of the disk is stopped. This prevents the adsorption of the lubricant to a disk for a head.

Filed: 1988-02-05
Abstract: PURPOSE:To obtain an information recording medium having a long life and high recording sensitivity by increasing the content of a protective material in the surface layer part of a recording layer and decreasing the content of the protective material and increasing the content of a material contributing to recording in the central part. CONSTITUTION:The recording layer 2 on a substrate 1 is formed of the material 12 which consists of a metal or semiconductor for recording information and the protective material 11 which consists of carbon and hydrogen. The mixing ratio of the material 12 and the material 11 is changed in the thickness direction of the layer so that the content of the material 11 is increased in the surface layer part than in the central part. Since the content of the material 11 is high in the part which is liable to be oxidized by contact with the atm., the oxidation resistance of the layer 2 increases. Since the central part is hardly oxidized, the degradation in the oxidation resistance is obviated even if the content of the material 11 is high. The oxidation resistance over the entire part of the recording layer is thereby improved and the total content of the material contributing to the recording is increased, by which the information recording medium having the long file and the high recording sensitivity is obtd.

IPC: H01M4/62
Filed: 1988-02-03
Abstract: PURPOSE:To improve cycle life of the battery in the caption by simultaneously adding antimony powder and silica powder as liquid absorbing material into positive active material. CONSTITUTION:0.05-0.5wt.% of antimony powder and 0.5-3.0wt.% of silica powder as liquid absorbing material are simultaneously added into positive active material of a sealed lead storage battery. It is thus possible to improve electrolyte-carrying ability and utility of active material by strengthening bonding strength among particles of active material. Therefore, cycle life of the sealed lead storage battery is improved. However, when added amount of the silica powder becomes less than 0.5%, the electrolyte-carrying ability is not improved, while, when more than 3.0%, bonding strength among the particles of active material is lowered so that it is not effective to add the antimony powder into the battery. Furthermore, when added amount of the antimony powder becomes less than 0.05 %, it is also not effective, while, when more than 0.5%, antimony is deposited on a positive plate so that self-discharge is frequently occurred to lower cycle life.
