Title: Controller of tracking position
Inventor: INADA HIROSHI
IPC: G11B7/085
Filed: 1982-10-14
Abstract: PURPOSE:To decrease the effect on a tracking position error detection due to a shift between a center shaft of a condenser lens and an incident optical axis, by performing identical movement to the condenser lens and a beam splitter in the radial direction of a disc. CONSTITUTION:The difference between two optical sensor outputs of a 2-split optical sensor 117 is calculated by a differential amplifier 118, a tracking position error signal is detected, and a tracking moving part 103 is driven in the arrow 111 by a tracking position control circuit 119 and a tracking actuator 110 so that a beam spot 107 is positined at the center of a tracking guide groove. Thus, the offset of the tracking position error signal due to the shift in the incident optical axis and the center axis of the condensor lens is decreased by performing identical movement to the condensor lens 105 and the polarized beam splitter 104 in the radial direction of the disc.

Title: Ceramic composition
Inventor: NAGAI HIROAKI
IPC: H01B3/02
Filed: 1991-06-25
Abstract: PURPOSE:To obtain the title composition improved in the bond strength between metallizing metal and the ceramic therefrom by incorporating a ceramic composition predominant in mullite with each specified amount of yttria as sintering auxiliary and borosilicate glass. CONSTITUTION:For example, a synthetic mullite raw material is incorporated with (A) 2-4wt.%, on an outer basis, of yttria and (B) 2.0-10wt.%, on an outer basis, of borosilicate glass. The resulting raw material is then incorporated with an organic binder, plasticizer and solvent followed by grinding and mixing in a ball mill into a slurry, from which a tape-shaped ceramic green sheet is formed through doctor blade technique. This sheet is subjected to raw processing and cut into chips, which are then coated with a metallic paste such as of W or Mo and fired in a wet hydrogen-nitrogen mixed gas. Thereby, borosilicate glass will be intruded as liquid component into mullite's inner pores, leading to increase in the bond strength between the metallizing metal and the resultant ceramic.

Title: Initializing control system
Inventor: NISHIBAYASHI HIROSHI
IPC: G06F1/24
Filed: 1988-07-20
Abstract: PURPOSE:To shorten a system rise time by informing a medium catch signal to a CPU through an unused signal line and allowing the CPU to decide the medium catch signal outputted from an FDD (floppy, etc.) device by a firmware built in it. CONSTITUTION:In case of raising a computer system, the CPU 3 executes system check after turning on a power supply, and after checking the normal operation of the system, executes IPL. At that time, the FDD device 1 informs the existence of a medium to the CPU 3 through an unused bus line 6. Since signal transmission to the CPU 3 is set up, the CPU 3 decides the signal, selects the FDD device 1 in which a medium is set up out of FDD devices 1 having priority and loads a program for raising the system. When no medium is set up in all the FDD devices, the CPU3 selects an HDD device 2 and loads the program. Since time-out time for FDD access can be omitted, the system rise time can be shortened.

IPC: G01T1/164
Filed: 1985-08-21
Abstract: PURPOSE:To enable a scintillation camera which can make the photomultiplying performance constant while easing burden on an operator, by rewriting the correction table with a correction when the energy sensitivity changes with time. CONSTITUTION:Position signals X and Y and an energy signal Z from a camera body 15 are inputted into an XY address selecting section 11 and a peak discriminator 13 respectively via an A/D converter 1. A spectrum data memory 12 has a matrix memory area and when the position of the signal Z is selected by the selecting section 11, the spectrum of the signal Z is memorized at X and Y selected positions thereof 12 through the discriminator 13. Then, when the center position of the reference spectrum as previously collected coincides with that of the current one, a signal to the effect is sent to a CPU 9. When they do not coincide, a signal corresponding to the deviation therebetween is outputted to the CPU 9, which generates a new Z correction value data to rewrite the correction factor (a) in a Z correction table 5. This saves an operator from time and labor for rewriting the contents while making the photomultiplying performance constant.
