Title: Pickup servo device
Inventor: HAYASHI HIDEAKI
IPC: G11B21/10
Filed: 1983-05-19
Abstract: PURPOSE:To offer a servo device not so much affected by a scratch on the disc or the external vibration by extracting a relative signal between a moving part and a fixed part of a pickup and mixing the signal with a servo error signal to apply servo. CONSTITUTION:An error is mixed to a reference voltage VR by a mixer 12 and amplified and fed to a track servo coil 6. On the other hand, the movement of the pickup to the fixed part is extracted by a detection coil 9. A track error signal 11 is obtained from the pickup at the same time. Each signal is fed back negatively via amplifiers B1, B2. When no feedback loop of the amplifier B1 exists, the gain as shown in fig. B withstanding an external vibration is set. Then a differentiating element is given to the B1 loop to attain the curve in Fig. A for the servo loop including the signal 11. The gain is attained for a loop gain required for the component for warp or the like and the system is not susceptible to the lower side band component of carrier and a scratch. The external disturbance to this disc system is applied as shown in Y. The servo loop to the external vibration X is supplied in-phase by the feedback amplifiers B1, B2, so that the loop gain is increased as shown in B.

Filed: 1980-07-01
Abstract: PURPOSE:To measure a separated space between galvanized steel sheet and a gas wiper nozzle by attaching a contact displacement meter and a noncontact displacement meter and operating the space from these output values through an adder and so on. CONSTITUTION:A contact displacement meter 4 transmits a displacement output value corresponding to the moved displacement (b) of a movable chip 5 connected to the top of a gas wiper nozzle 3 with a prescribed distance (d) to an adder. The displacement output value corresponding to the separated distance (a) of a noncontact displacement meter 6 attached to a galvanizing steel sheet with a prescribed distance (c) from the contact displacement meter 4 is transmitted to the adder 7. The adder 7 addes both the displacement output values (a) and (b) of the adder 7 and the succeeding adder 8 adds the output values (a+b) of the adder 7 to the output value (b) of a constant setter 9 to detect the separated distance (e) between the galvanized steel sheet 1 and gas wiper nozzle 3. Thus, the separated space between the galvanized steel sheet and gas wiper nozzle can be measured precisely.

IPC: G03B13/36
Filed: 1979-07-13
Abstract: PURPOSE: To prevent the deterioration of distance-measuring accuracy by providing a light-shielding member to the semi-transparent mirror of a main mirror, shielding  the reverse incident light to a distance- measuring photodetector from a finder at the subject observing and shielding the reverse incident light from the semi-transparent mirror part of the main mirror at the exposing.  
     CONSTITUTION: A light-shielding plate 16 is supported to a main mirror supporting plate 4 turnably by a shaft 17 and the distance-measuring effective luminous flux La passing the lens passes through the semi-transparent part of the main mirror, is reflected by a movable sub-mirror and enters a focusing-detecting photodetector 15 by way of a beam splitter 14. On the other hand, the reverse incident light Lb from the finder is shielded light-shielding plate 16. At the exposing, the light-shielding plate 16 shuts off the semi-transparent part of the main mirror, by which the reverse incident light from the finder into the mirror box is blocked. On the other hand, a sub-mirror 11 rotates in the direction of an arrow to prevent the luminous flux La from being shielded. These prevent harmful light from entering the photodetector and degrading the accuracy of distance measurement.

Title: Air-fuel ratio controlling apparatus for internal-combustion engine
Inventor: KOBAYASHI NOBUYUKI
IPC: F02D41/14
Filed: 1984-05-07
Abstract: PURPOSE:To prevent degradation of the engine performance, by providing a means for restricting the variation range of the correction value of closed-loop control within a particular range in a lean combustion type engine. CONSTITUTION:An air-fuel ratio detecting means (b) detects the air-fuel ratio of an internal-combustion engine (a) by detecting the concentration of a particular component contained in the exhaust gas of the engine. A means (c) calculates the correction value for closed-loop control of the air-fuel ratio by comparing the detected air-fuel ratio with an aimed air-fuel ratio set at a value leaner than the theoretical air-fuel ratio. A restricting means (d) restricts the variation range of the correction value for closed-loop control of the air-fuel ratio within a particular range. A closed-loop control means (e) executes closed-loop control of the air-fuel ratio according to the restricted correction value for closed-loop control of the air-fuel ratio. Further, said restricting means (d) is so designed that the variation width of said particular variation range of the correction value on the lean side of the air-fuel ratio is smaller than that on the rich side. By employing such an arrangement, it is enabled to prevent degradation of the engine performance by controlling the air-fuel ratio to an excessively lean value.

Abstract: PURPOSE: To simplyfy addition of an arbitrary program to improve the vehicle control capability, by storing the flag, which concerns presence and absence of the additional ROM where the arbitrary program is stored, in the CPU in the microcomputer for vehicle control.  
     CONSTITUTION: When electric power is supplied by a start switch and so on, a signal indicating whether option ROM4 storing another control program exists besides standard ROM3 storing a prescribed control program or not is transmitted from signal generator 10. This signal transmitted from signal generator 10 to data bus 5 is written to a specific address of RAM2 as flag information. When the jump instruction to the control program in option ROM4 is read out by the control program in standard ROM3, this flag information is inspected to decide whether the jump instruction should be executed or not. Consequently, an arbitrary control program can be added and executed simply, so that the vehicle control capability can be improved easily.
