Title: Time base corrector
Inventor: SAITO ISAO
IPC: H04N9/896
Filed: 1987-07-03
Abstract: PURPOSE:To constantly correct a normal time axis even when a track-jump is executed at a CLV disc by forcibly shifting a reading timing for a constant time only when the time difference between a writing and a reading goes to be within a prescribed time difference by a time axis fluctuation. CONSTITUTION:The titled collector is provided with timing detection circuits 9-11 to detect the time difference between a writing timing and a reading timing to the same digital data written and read into a memory circuit 3 and to output a detecting signal when it reaches within a prescribed time difference, and timing shift circuits 12 and 16 to forcibly move a reading timing by the input of a detecting signal only for the time of the integer-fold of an approximately horizontal scanning period and of the integer-fold of a color sub-carrier cycle. Thus, the time difference is provided between the writing and the reading on the memory circuit 3, the reading timing is positioned outside the time axis fluctuation range of the writing timing and even when a track jump is executed at a CLV (constant linear velocity) disc, a reproducing image signal that a normal axis correction is executed can be obtained.

Title: Input/output controller
Inventor: HARUTA MASATOSHI
IPC: G06F15/16
Filed: 1990-06-21
Abstract: PURPOSE:To transfer data at a high speed by using an inverter and a selection means to convert a data form and therefore omitting a special software program needed for conversion of the data form. CONSTITUTION:When the data are transferred between both devices 2 and 3 having the store forms where the different ways of arrangement are secured between a higher rank half and a lower rank half of the transfer data, an inverter 15 inverts the lowest rank bit of the address that is given to a buffer memory 4 from an address circuit 5. Thus a higher rank half is replaced with a lower rank half for the data to be stored in the memory 4 even though the addresses given from the circuit 5 are gradually increased every time the data are transferred by half. Thus the data can be transferred between both computers having different data types with no software processing required. Then the deterioration of the data transfer performance can be evaded.

IPC: H04N5/335
Filed: 1981-10-16
Abstract: PURPOSE:To improve both output voltage and sensitivity, by increasing the junction capacity of an N type diffusion layer at a photoelectric converting part without producing any defect such as an increase of the chip area, etc. and decreasing the reconnection of a positive hole and an electron produced by photoelectric conversion. CONSTITUTION:A P type capacity conductor layer 10 is formed on an N type diffusion layer 2 in a photoelectric converting region. The layer 10 is connected to a light shielding aluminum layer 9 through a contact. An insulated oxidized film 8 is drilled by a selective etching process before the layer 10 is formed, and a P type semiconductor layer 11 of high concentration is formed by the selective diffusion. Then the layer 10 is vapor-deposited to form an aperture of the photoelectric converting region. The layer 2 has the junction capacity to both the surface of a P type semiconductor substrate 1 and the layer 10. Thus the electric charge quantity stored at the layer 2 increases with a high output. At the same time, the positive hole is extracted by the layer 10 among the positive hole and the electron which are produced by the junction of the layers 2 and 10.  Thus the sensitivity is increased.

Inventor: OKAMOTO YASUO
IPC: F01D5/14
Filed: 1979-12-19
Abstract: PURPOSE: In a turbine blade having specific area wherein a fluid running along the surface on a negative pressure side is decelerated, to pevent a damage of the turbine blade during transonic operation by permitting the fluid to pass through it from the negative pressure surface in the decelerating area.  
     CONSTITUTION: A blade P having a negative pressure side C and a pressure side D is moved in the direction R. Several hiles E are made through up to a decelerating area W on the negative pressure side C. As a fluid flows through the holes E, a pressure difference may be reduced between the pressure and negative prssure surfaces created when a shock wave runs against the decelerating area on the negative pressure side. Additionally, the shock wave is prevented from making severe vibration on this area, resulting in an application of a seriously fluctuating pressure on the blade P, and thus, a damage of the blade P can be prevented.
