Title: Reading out circuit
Inventor: SHIMAUJI MASAHIRO
IPC: G11B5/09
Filed: 1989-04-28
Abstract: PURPOSE:To expedite the converging of a transient response and to allow a high-speed switching operation by detecting the fluctuation in a bias voltage arising from the transient response and diminishing the time constant of a differentiating circuit for removing DC during the time when this fluctuation exceeds the prescribed voltage. CONSTITUTION:A head output signal 21 is amplified by a prescribed gain in a preamplifier 1 and is outputted when the preamplifer 1 is in an operation state. The time constant of the differentiating circuit constituted of a capacitor 9 and a resistor 10 is set sufficiently larger than the period of the reading out signal. The value of a resistor 11 is set sufficiently smaller than the value of the resistor 10 and the time constant determined by the on resistance values of the capacitor 9, the resistor 10, 11 and an analog switch 13 when the analog switch 13 is on is set sufficiently smaller than the value at the time when the analog switch is off. The transient response converging time of an AGC input signal l26 is shortened and the high-speed reading operation is enabled in this way.

Abstract: PURPOSE:To provide highly efficient liquid phase epitaxial growth of a single crystal thin film on a single crystal substrate by preventing a local decrease in temperature at the boundary surface of a solution by means of a crucible which is made movable between a heating and a pre-heating room. CONSTITUTION:A solution 1 at room temperature in a crucible 2 is initially heated to approx. 1,200 deg.C in a pre-heating room 10C. Before reaching a saturation temperature at which the temperature lowering operation is to be started towards a growing temperature, an agitator 19 is lowered to agitate the solution while lowering its temperature so as to keep the solution temperature even. After a specified growing temperature is reached, the agitator 19 is lifted up, a heat shielding plate 17 is extracted and the crucible 2 is moved to a heating room 10a for epitaxial growth through a crucible moving mechanism 22. When the crucible reaches the heating room 10a a crystal substrate 9 supported by a supporter 8 is submerged in the solution for the growth, then, after the growth, it is lifted up. The crucible 2 is returned to the pre-heating room 10C at the completion of the growth by means of the moving mechanism 22. This temperature cycle of up- keep-down is repeated.

Title: Intermittent driving device of magnetic tape
Inventor: HONJO MASAHIRO
IPC: H04N5/783
Filed: 1980-08-14
Abstract: PURPOSE:To realize the stable slow and still reproduction, by starting an intermittent drive VTR when the amount of shift of a tape reaches a prescribed value in case a capstan drive motor has the start, constant speed and speed reduction states respectively when the tape travels. CONSTITUTION:A frequency generator is directly connected to a capstan motor in an intermittent drive system VTR in which a capstan drive motor has the start, constant speed an speed reduction states respectively when a tape travels. The pulses FG proportional to the travel extent of the tape are counted by a down- counter 1 from the generation of control pulse CTL which is reproduced from the  tape, and a brake pulse BP is produced 3 when the counting reaches a prescribed  number in order to perform a distance control. As a result, no variance is produced  for the tape stopping position although the time point of generation of the pulse  CTL is not in the constant speed state of the tape or some fluctuation is caused in the constant speed state of the tape. This always ensures the stable slow and still  reproduction.

Title: Control system of history storage device
Inventor: UEMOTO SHIGEMI
IPC: G06F11/34
Filed: 1982-06-30
Abstract: PURPOSE:To utilize a history memory effectively, by displaying history data by one-cycle for registering, comparing it with new data, and inhibiting writing to the history memory when no difference is recognized. CONSTITUTION:Various control data are extracted as, for example, X, (a), (b), (b), (c)... as shown in the figure, stored in a register 5A, and then transferred to a register 5B delayed by one-cycle. The outputs of the registers 5A and 5B are compared with each other by a comparing circuit to detect whether they coincide with each other or not. When dissidence is detected, the contents of the register 5B are written in the history memory successively, but when a coincidence signal is detected, the writing operation is inhibited. Consequently, required minimum data reside in the history memory, and said memory is prevented from being occupied by the samd data.

Abstract: PURPOSE:To reduce the size of each LRU table, to realize an LRU approximation system at a high speed and to execute the substitution processing of plural request source programs by hierarchizing an LRU table into plural stages. CONSTITUTION:When the read request of data required for the request source program 1 is generated, a high-speed storage device 4 is retrieved based on a data identifier for specifying the data desired to read in. If the data are present on the high-speed storage device 4, the data are taken out and simultaneously, a reference bit part is set to the LRU set table while starting from the LRU set table 6 of a first layer successively to the lower order table, and if the data are not present thereon, the entry of the maximum value of a counter part is retrieved from the tables while starting from the LRU set table 6 of the first layer successively to the lower order table, and substitution processing is executed. Since the size of one table is made as small as 32 entires by hierarchizing the LRU table into four hierarchies, the LRU approximation system can be executed at a high speed.
