Patent JP-S61233442-A (JP)
Title: Optical head device
Inventor: KUWAYAMA TETSUO
IPC: G11B7/135
Filed: 1985-04-09
Abstract: PURPOSE:To eliminate the effects of the wavelength variance of a light source by using a means which increasing the size of the photodetecting surface in the direction where it is diffracted by a diffraction grating in comparison with the size in the direction orthogonal to the first mentioned direction. CONSTITUTION:The traveling direction of the diffracted light 11 is changed slightly by the wavelength variance of a light source 1. The change of direction due to said wave motion variance is coincident with the direction diffracted by a diffraction grating. Therefore 11a'-11c' have vertical fluctuations to the distribution of light quantity of 11a-11c respectively. Here photodetecting surfaces 13a-13d of a photodetector 13 have relatively large sizes in the direc tion where the luminous flux is shifted by said wavelength variance so that the fluctuation of the light 11 due to the wavelength variance of the light source 1 is included in terms of the substantial efficiency of photodetection. At the same time, the dividing line of each photodetecting surface is set in parallel to said direction. Thus the output of each photodetecting part is not substantial ly affected despite the wavelength variance of the light source. This attains the correct auto-focusing and auto-tracking actions.

Abstract: PURPOSE:To decrease the influence of mechanical orientation and to equal the degrees of orientation in arbitrary positions on tracks by impressing magnetic fields perpendicularly to the surface of a raw sheet in the unsolidified state of a magnetic coating compd. to preorient the compd. in a perpendicular direction, then subjecting the surface to random treatments. CONSTITUTION:The magnetic coating compd. is coated on a base film and the raw sheet 1 in the unsolidified state is sent to carrying rollers 2, 3 by which the sheet is moved at a specified direction in the direction of an arrow 4. The width of magnets 7, 8 for perpendicular orientation is slightly larger than the width of the sheet 1 and the magnets are so disposed that the N poles and the S poles face each other in the form of sandwiching the raw sheet. The sheet 1 is sent to the carrying drums 2, 3 and passes the spacing between the magnets 7 and 8 for perpendicular orientation by which the sheet is preoriented in the perpendicular direction. The sheet 1 past the spacing between random orienting devices 5 and 6 is randomly oriented by the devices 5, 6 facing each other. The influence of the mechanical orientation is thereby decreased and the degrees of the orientation in the arbitrary positions on the tracks are equaled.

Title: Glazing system
Inventor: ANDO YOSHITAKA
IPC: C04B41/86
Filed: 1989-03-27
Abstract: PURPOSE:To prevent the production of defective articles through automatically controlling the delivery of a glaze fluid by combination of a conveyor, a nozzle, measuring devices and a controller so as to act specifically. CONSTITUTION:When the glazing amount for each base calculated by a weight operator 23 differs from the corresponding proper value, the flow information for the glaze fluid necessary for doing away with the difference enters a flow regulator 14 via a weight regulator 24. At this point, the above flow is compared with the flow observed, and an automatic control is made in such a manner that the difference between the former and the latter flows enters a glaze pump controller 17 and the resulting output changes the rpm of a glaze pump 8, effecting proper level of the delivery of the glaze fluid through a nozzle 7. Along with this, the density of the glaze fluid is ensured to be maintained at a proper level specified in advance by actuating a water pump controller 19 through a density regulator 16 and a ratio-setting device 18 to effect control of the delivery for a water pump 2. A pressure gage 25 is connected to a glaze fluid pressure feed pipe of the nozzle 7, and an alarm 26 will be actuated when the pressure variation increases beyond a specified range.

IPC: G06F3/06
Filed: 1980-06-03
Abstract: PURPOSE:To continue control without interrupting a muCPU, by providing a floppy disk controller with a memory for reading and writing-in. CONSTITUTION:When a muCPU1 reads in data from a floppy disk 4, the data is written in a reading buffer 61 temporarily via a floppy disk controller 3, which then transfers a completion signal to the buffer 23 of a memory 2. On the other hand, when the muCPU1 writes data in the buffer 23 onto the disk 4, one block of data is written in the writing buffer 62 of a memory 6 and also written onto the disk 4. On the transfer to the buffer 62, a completion signal is sent to the muCPU1. Thus, while the controller 3 is being accessing the disk 4 and transferring the data, the muCPU1 performs another task.
