Title: Optical head device
Inventor: SHIBATA SATOSHI
IPC: G11B7/135
Filed: 1990-09-03
Abstract: PURPOSE:To make light intensity distribution axially symmetric to the optical axis while reducing the loss of light quantity as much as possible with the small number of parts without deviating the optical axis by using optical filters for a beam shaping device so that the transmittivity is gradually decreased from the center to the outer periphery and the decreasing rates can be different from each other in two directions intersecting orthogonally with each other. CONSTITUTION:In respect to a light source 1 for which the light intensity distribution is different in two directions intersecting orthogonally with a face perpendicular to the optical axis, optical filters 5 with characteristics to gradually decrease the transmittivity from the center to the outer periphery and to make the decreasing rates different in two correspondent directions are disposed. In this case, since one direction having the light intensity distribution with wide spreading is made corresponding to one direction of the optical filter 5 having the larger decreasing rate of transmittivity for a beam emitted from the light source 1, the light intensity distribution after passing through the optical filter can be made coincident with the other direction having the light intensity distribution with narrower spreading. Thus, the obtained light beam can be made axially symmetric to the optical axis, and the optical axis is not deviated as well.

Abstract: PURPOSE:To obtain the picture signal data corresponding to the optical information without using a compensating circuit by reading out the optical detection information at the same time point of a transient state or in a steady state to a photodetecting element having the transient response characteristics. CONSTITUTION:The voltage is applied to each input terminals 61-6n of blocks 51-5n from a voltage applying circuit 10 which consists of a voltage scanning circuit 3 of a shift register, etc. and N units of exclusive OR gates 111-11n corresponding to blocks 51-5n.

Title: Transfer system for width extension data
Inventor: TSUZUKI FUMIO
IPC: G06F13/38
Filed: 1988-09-16
Abstract: PURPOSE:To attain the high-speed transfer of the data on the data width extension by sending a pattern designated in an extension bit width transfer mode via a data signal line while performing the designation of addresses via an address signal line and then carrying out the transfer of data via both signal lines. CONSTITUTION:In a normal state the address and data signals are transmitted and received between the transfer devices 70 and 71 via an address signal line 72 and a data signal line 73 respectively. When the extension is desired for the width of data that can be transferred at one time, the device 70 transmits first an address signal via the line 72 and at the same time sends a specific pattern designating that the data width is switched to an extended mode via the signal line 73. The specific pattern is detected by a transfer mode detecting circuit 76 and therefore a data transfer switch control circuit 77 switches the transfer mode to the data width extension mode. Then the device 70 uses both lines 72 and 73 as the data signal lines to extend the transfer data width and transfers the data to the device 71. The data having its extended width is stored in a data register 75.

Abstract: PURPOSE:To prevent a member to be locked from being unlocked in the state which does not satisfy conditions necessary for unlocking even if an unlocking member is moved, by providing additionally an auxiliary member interlocking only with the unlocking direction of a locking member to the locking member and interlocking the auxiliary member with a control member interlocking with other means. CONSTITUTION:When conditions actuating mechanisms arranged on the intermittent gear side are not satisfied, a lock controlling member 15 is moved in the right direction in the shown figure, brought into contact with a projected part 11d and located on a position pulling the projected part 11d. Driving force is transsmitted from a driving source to an unlocking member 4 and the unlocking member 4 starts to advance. But the unlocking member 4 is separated from the auxiliary member 11 by the work of the lock controlling member 15 so as not to be engaged, so that the auxiliary member 11 is still rotated in the direction separated from the intermittent gear 1 in spite of the advance of the unlocking member 4. Said force is not transmitted to a locking member 5 and a locking part 5a of the locking member 5 is still engaged with an engaging pin 7 of the intermittent gear 1 as it is to keep the locking state.

Abstract: PURPOSE:To stick tightly a wash coat layer by subjecting a surface of a metallic foil consisting of stainless steel to aluminum surface coating treatment and thereafter heat-treating it in the high-temp. atmosphere. CONSTITUTION:In relation to a surface structure of a metallic carrier used for a catalyst for purifying an exhaust gas, a metallic foil made of stainless steel is used as the metallic foil and the surface of this metallic foil is subjected to aluminum surface coating treatment and thereafter heat-treatment is performed therefor in the atmosphere of 470-1,100 deg.C. Thereby Fe-Al intermetallic compd. contg. Fe3Al is formed on the surface. This intermetallic compd. has a porous block-shape and is thickly grown on the range over the whole face of the surface. Therefore the peeling of a wash coat layer and the intermetallic compd. layer from the surface of the metallic foil is not thoroughly caused and tight adhesion of the wash coat layer is attained.

Filed: 1984-11-08
Abstract: PURPOSE:To provide a small and inexpensive servo clinometer having high stability and accuracy, by realizing an inclination angle detection system according to a zero point method utilizing the displacement of the boundary surface of a magnetic fluid. CONSTITUTION:Air bubbles 53 are ready to move in proportion to the angle of inclination of a machine main body, that is, a container 51 and, when a magnetic field is applied by the servo coil in the side where air bubbles 53 come together, said air bubbles 53 are ready to return to the original position. Therefore, if a servo machine is operated as the secondary coil of a differential transformer so that the output of a detection coil comes to zero, the above mentioned angle of inclination corresponds to the magnitude of the exciting current of the servo coil according to the intensity of the applied magnetic field. That is, the angle of inclination to be calculated can be measured by the current of the servo coil at this time. That is, the primary coil of the differential transformer 62 is excited by the output from the exciting circuit 61 of the differential transformer and the detection outputs from the secondary coils at both sides thereof are processed by a differential comparing circuit 63 and the processing of a signal is performed so that a drive circuit 65 is operated so as to hold the above mentioned equilibrium state by a servo coil driving processing circuit 64.
