Title: Malfunction checking system of hole sensor for cartridge tape
Inventor: FUJIOKA ICHIROU
IPC: G11B15/06
Filed: 1982-02-03
Abstract: PURPOSE:To prevent malfunction such as misjudgement of tape stop position and tape winding, by using the format specifications relating to holes as a checking pattern and checking the operation of hole sensors. CONSTITUTION:The operation executed at first is 60-inch running of a tape in the forward direction (the reverse direction at rewinding) through the start of tape rewinding. When a hole signal is detected on the way of tape running reaching 60 inches, the signal information, BOT, L.P/E.W or EOT, is stored in an RAM of a control circuit at each detection. Simultaneously, according to the algorithm of the hole signal sequence check[1], whether or not there is a failure in the hole sensor output signal is discriminated. After the hole signal sequence check, the tape is stopped and the hole sensor signal sequence check[2]is performed.

Title: Rotary magnetic head
Inventor: NAGATA YOSHINOSUKE
IPC: G11B5/53
Filed: 1978-02-13
Abstract: PURPOSE:To record high frequency range signals in high density in a high coercive recording medium by applying coil winding integrally to a core chip comprising disposing metallic magnetic cores on both sides of a non-magnetic material under specific conditions. CONSTITUTION:If the thickness relations are defined at W>Wa+Wb at the time of forming the core chip by providing metallic magnetic cores 2a, 2b of thicknesses Wa, Wb on both sides of a non-mangetic plate 1 of a thickness W, then a pair of head gaps of a pair of rotary magnetic heads of the same shape opposedly mounted to a rotary disc precede and form a magnetic track with the magnetic track formed by a different pair of head gaps of the subsequent another heads in-between. Hence, if the azimuths of the head gaps 4, 4 are the same, they may cope with the necessary guard band width and if the azimuths of the gaps 4 are different, the need for the guard band is eliminated, hence the thickness can be W=Wa+Wb. Thereby, high frequency range signals may be recorded in high density in a high coercive recording medium.

Title: Reduced pressure vapor growth device
Inventor: DEN YASUHIDE
IPC: C23C16/44
Filed: 1990-01-25
Abstract: PURPOSE:To prevent the generation of dust and to improve a yield as well as to allow continuous operation by switching lines of discharge pipings provided in plurality prior to opening of a hatch after film growth and purging the discharge piping used for the film growth with N2 to use always the clean discharge piping. CONSTITUTION:The inside of a reaction tube 1 is pulled to a vacuum by a vacuum evacuation system and once an N2 atmosphere is maintained therein, then the film growth is executed by supplying SiH4 and N2O as reactive gases in the case of, for example, the formation of a CVD oxide film by using the above-mentioned reactive gases. Since the N2O is poor in oxidative property, the unreacted SiH4 remains while this gas is held adsorbed on the inside walls of the discharge pipings. The oxygen in the atm. and the unreacted SiH4, therefore, react and fine dust suspends in a furnace core tube when the hatch 3 is opened at the time of ejecting a wafer 4 from the furnace. This fine dust acts as the nucleus for the dust at the time of the next growth. The film growth is, therefore, executed by the discharge piping 6a and the vacuum evacuation system (a) as the vacuum evacuation system for the discharge piping. The piping and system are then switched to the discharge piping 6b and the vacuum evacuation system (b) by an automatic shut off valve 10 before the hatch 3 is opened. The piping 6a is purged with the N2 by the supply system 5 to remove the adsorged gas after the switching. The next film growth is executed by the opposite discharge piping and vacuum evacuation system.

Filed: 1990-01-26
Abstract: PURPOSE:To prevent a filter from melting and preheat particulates by heating a heater buried in the filter, and burning the particulates deposited on the filter and also forcing reverse flow of high pressure air from downstream side toward the filter. CONSTITUTION:When particulates are deposited on a filter 1, a switch 11 is turned on so as to electrify a heater 9 buried in a plug 7b for closing the hole 6 of a porous element 1a. The particulates are burned by heating the heater 9. At this time, a valve 17 is opened, while a valve 18 is closed, and exhaust gas is guided to flow from a bypass passage 16 toward a cleaned gas exhaust pipe 5 instead of its flow in a trap casing 2. And at the same time, a control valve 13 is opened, then high pressure air supplied from a pressure source 12 is guided to blow from a back flow air nozzle 14 toward the lower end surface of the filter 1, while performing adiabatic expansion. It is thus possible to cool the porous element 1a by means of reversely flowing high pressure air while improving burning efficiency by preheating high pressure air.
