Title: Numerical control device
Inventor: KITA YASUHIKO
IPC: G05B19/4155
Filed: 1985-01-21
Abstract: PURPOSE:To make a variable table unnecessary by using a variable number as a memory address to access a memory directly and reading out directly a numerical value or substituting the numerical value into the variable directly. CONSTITUTION:If a variable is designated in the processing of a main routine, a program analyzing circuit 5 supplies the variable number to a variable referring means 6; and if it is necessary to substitute a numerical value into the variable, the circuit 5 supplies the variable number and the numerical value to a variable writing means 7. The variable referring means 6 understands the variable number as an address of a memory 8 and refers to the memory 8 directly to read out the numerical value in this address and transfers it to the processing of the main routine. The variable writing means 7 uses the variable number supplied from the analyzing circuit 5 as an address of the memory 8 to write the numerical value in this address. A control signal output circuit 10 outputs the operation processing result of the analyzing circuit 5 to an object 3 to be controlled.

Title: Magnetic recording device and magnetic reproducing device
Inventor: SAKAZAKI YOSHIHISA
IPC: G11B20/12
Filed: 1995-01-20
Abstract: PURPOSE: To unnecessitate the permuting of reproduced data at the time of a backward high- speed reproducing and to more improve the number of speed multiplications of a high-speed reproducing capable of improving the number of speed multiplications than that of convention ones even in the case the trace locus of a head is different in a recording time and a reproducing time. CONSTITUTION: Data for a forward high-speed reproducing and data for a backward high-speed reproducing are alternately recorded on the recording tracks of a magnetic tape 8 by controlling a changeover switch 3 with an output control means 6. In this case, respective data for the forward and backward same high-speed reproducings are recorded over tracks of the number of prescribed multiple speeds×2 with the interval of four tracks. When the magnetic tape 8 is reproduced at high-speed in the reverse direction, the permuting of reproduced data is unnecessitated. A data correction or error deciding circuit 11 discriminates whether the data area for a high-speed reproducing of the magnetic tape is normally reproduced or not.  In the case the area is not discriminated normally, a tape drive control circuit 12 controls a capstan 13 so that the reproducing becomes the reproducing of the speed of (n+0.5) multiplications which does not exceed the number of speed multiplications/2-1. Thus, even in the case the trace locus is different in the recording time and the reproducing time, the data area for the high-speed reproducing can be surely reproduced.

IPC: H01S3/06
Filed: 1996-01-19
Abstract: PURPOSE: To obtain an optical composite module which is low in light loss and is improved in utilization efficiency of exciting light. CONSTITUTION: A square or rectangular casing 5 mounted with optical fibers 6a, 6b respectively on its two side faces facing each other has an exciting light source device 21 and an optical separator 30 for separating the exciting light and signal light.

The exciting light source device 21 is so arranged that the exciting light emitted from the device is made incident from a direction perpendicular to the progressing direction of the signal light passing the optical separator 30.  The incident exciting light on the optical separator 30 is transmitted in the direction opposite to the progressing direction of the signal light. The optical separator and the exciting light source device are arranged within the same casing and the generated exciting light is made incident directly on the optical separator and, therefore, the conversion loss of the exciting light is lessened.
