Title: Surface acoustic wave filter
Inventor: YAMADA HIROMICHI
IPC: H03H3/08
Filed: 1984-08-13
Abstract: PURPOSE:To make a pass band broad and to reduce an in-band ripple by providing respectively a normal interdigital electrode to the center and an interdigital electrode with cross width weighting to both sides. CONSTITUTION:The interdigital electrode 23 is of normal type and the interdigital electrodes 24, 25 are applied with cross width weighting. Then even if tuning is applied by a coil, the frequency characteristic is in a form expanded at both extremes. Thus, the pass band is made broad. Further, the resistive component of the output side is not so much changed in a remarkably wide frequency range. Thus, the impedance matching is applied at a wide frequency range. As a result, the ripple is reduced at the wide frequency range.

After heat treatments of cooling and recuperation are applied to the part in the region of specific thickness from the surface layer of the resultant steel bloom, finish rolling is performed. Successively, the surface layer region is recuperated and further subjected to cooling treatment under specific conditions.  By this procedure, the average crystalline grain size in the central part of the steel material is regulated to <=30μm and the structure of 10-60% of the steel material is formed into martensitic structure 7 and further, the structure in the region of 10-33% thickness from the surface layer is formed into superfine, grained structure of <=3μm average ferrite grain size.

Abstract: PURPOSE:To change over from the water cooling roll process to the water hardening process and from the water hardening process to the water cooling roll process with a simple operation without changing the pass line, by installing the water hardening device and water cooling rolls in series so that they may be changed over to each other, and by installing a pickling and neutralizing facility at the outlet side of the furnace. CONSTITUTION:When high tension steel material is manufactured with a continuous annealing facility, heated an soaked strips are quenched at a water hardening device 15 after passing through a primary cooling zone 12, and then, enter into an over aging treatment zone 13. At this time, water cooling rolls 17 of a water cooling roll device 16 have moved upward or downward, and the strip runs through the water cooling roll zone while it is supported only by rolls 17a and 17b at both ends of the water cooling rolls 17. When mild steel material is manufactured, water supply to the water hardening device 15 is stoped, and cooling water is supplied into te water cooling rolls 17. Then, the water cooling rolls 17 are contacted to strips and the cooling is started. The strip then enters into a successive pickling and neutralizing facility 19. When this mechanism is applied, coolings by means of either the water hardening process or the water cooling roll process are freely selected.

Title: Pulse delaying circuit
Inventor: SUZUKI TERUO
IPC: H03K5/13
Filed: 1982-09-29
Abstract: PURPOSE:To simplify the configuration of a pulse delaying circuit extending a pulse interval and to extend the pulse interval between two pulse signals or more by comparing the number of input and output pulses, and at the time of coincidence, stopping the operation of an oscillator. CONSTITUTION:An input signal is delayed by the oscillator 34 and a frequency divider 38 and the counted data of a counter 30 counting the number of input pulses is compared with that of a counter 40 counting the number of output pulses. If these counted values coincide with each other, a coincidence output terminal A=B is turned from the L level to the H level, the oscillator 34 stops oscilating and an output from the frequency divider 38 is stopped. Therefore, the same number of pulses as the number of input pulses is outputted from a two- input gate circuit 36 only in the period that the coincidence output terminal A= B is in the L level. In addition, the pulse interval between output pulses is extended by a prescribed period.

Title: Collecting system of fault information
Inventor: ISHIKAWA YOSHIO
IPC: G06F11/34
Filed: 1980-12-03
Abstract: PURPOSE:To reduce the necessary time for a stored program type computer system, by transferring only the information different from the initial information among the memory information in a main storage device to an external auxiliary storage device. CONSTITUTION:A software fault detector ALM receives the signal with every certain period of time and confirms the normal state of a system. If an error arises in the software, no signal is received at the detector ALM although a certain period of time elapses. Thus the ALM detects the fault of the system and applies an interruption to a processor CC. Receiving the interruption, the processor CC transfers the fault information collecting program P3 in an external auxiliary storage device EMEM2 to a main storage device MEM and gives a start. The program P3 performs a comparison between the memory information in the storage region where no inhibition is given to the writing within the device MEM and the data P2 of the system program in an external auxiliary storage device EMEM1. And only the dissident memory information of the MEM is transferred to a file P4 in the EMEM2 to reduce the necessary time.

Title: Manufacture of ce substituted garnet and optomagnetic recording medium
Inventor: MAIKERU ARETSUKUSU
IPC: G11B11/10
Filed: 1989-06-30
Abstract: PURPOSE:To freely vary magnetic characteristic compensating temperature of coercive force, aspect ratio, etc., by sputtering a film or heat treating after film forming in an inert gas atmosphere containing an oxidative gas or reducing gas in a method of manufacturing a specific Ce-substituted garnet. CONSTITUTION:In a method of manufacturing a Ce-substituted garnet represented by a formula (1), oxygen amount in the film is controlled to alter valance of Fe in the film. Or, the formed film is heat treated under suitable oxygen partial pressure. Since the valence of Fe is very sensitive to oxygen amount, fine oxygen amount control is required in this case. Large aspect ratio, coercive force, compensating temperature necessary as an optomagnetic recording medium are controlled in the garnet, and the characteristic is freely controlled by controlling the oxygen partial pressure at the time of sputtering, and controlling oxygen concentration at the time of heat treating after film forming.

Abstract: PURPOSE:To perform the searching accurately with low cost and then automatically and quickly when necessary by forming the program searching information through N tracks (N>=2) with a track defined as the information unit and applying such signal processing that gives the significant difference to the record/reproduction characteristics original to the corresponding device. CONSTITUTION:Both tracks A and B are defined as a group, and the retrieving information is given only for a prescribed period immediately before the picture information with said one group defined as a unit. For this information applying means, non-record state of signal is formed according to a prescribed style. In other words, no-record parts 30 where no signal is recorded at all are formed in a prescribed section for each unit of a group on a magnetic tape 1. When the tape 1 is reproduced at a high speed, the parts 30 produce just noises. Then no envelope curve is obtained at a part corresponding to the part 30 for a reproduced waveform of a scanning line 20 of a head A. With addition of the parts 30 to the tape 1, an envelope curve signal appears every 2T compared with conventional time T. Thus the retrieving information is available by making use of the difference between T and 2T.
