Title: Information recorder
Inventor: SAITO KAZU
IPC: H04N5/225
Filed: 1990-02-15
Abstract: PURPOSE:To decrease a recording timing delay by providing a means bringing a function section whose response time is comparatively long into a prescribed setting state prior to the changeover of the operating mode from the non- recording mode into the recording mode. CONSTITUTION:Prior to the changeover of the operating mode into the recording mode, a function section whose response time is comparatively long such as an AF lens actuator 3 or a macro lens actuator 7 is used to drive a focus lens 2 or a macro lens 6 to a prescribed setting state for the start of recording. That is, the focus lens 2 is driven to an initial reference position and the macro lens 6 is driven to a saving position at the outside of a pickup optical path. Thus, the drive time to the initial position with a comparatively long response time is not required in the recording processing and shutter operation with very less wait time is attained based on a signal of a release SW 17.

Title: Motor control device for switching mechanism
Inventor: MATSUMOTO TAKASHI
IPC: H02H7/085
Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To prevent a motor driving circuit from being damaged due to the reverse connection of a power supply. SOLUTION: A relay interposed between a motor 1 and a power supply, is normally in a condition that the motor 1 is cut off from the power supply. A control circuit 7 determines the rotating direction of the motor 1 based on the operating condition of a P/W switch 10 so as to output either one of an UP signal or a DOWN signal. The relay 2 is thereby actuated by the output signal, and its contact is changed over to a contact corresponding to the signal so as to be connected with the power supply of the motor 1. In a case that the motor 1 is rotated to the direction that a window is closed, interleaving detection by means of motor current is performed by an interleaving detection circuit 11, and concurrently, a driving FET 3 permits current flowing to the motor 1 to be gradually increased at the time of starting based on a PWM signal outputted by the control circuit 7. And when the control circuit 7 is interleaved, the motor is reversed in rotation so as to be controlled. By this constitution, when the polarity of the power supply is reversely connected, the control circuit 7 will never be actuated because of the function of a diode 6, the relay 2 stays in a normal condition, and the FET 3 can thereby be prevented from being damaged.

Title: Magnetic head
Inventor: IMAOKA HIROFUMI
IPC: G11B5/23
Filed: 1986-02-20
Abstract: PURPOSE:To eliminate the leakage near the adhesive part of an adjacent track due to a leakage magnetic field by forming a butted face having the same plane as a magnetic gap forming face and providing a notch in nearly perpendicular contact to a gap and led to a winding window to a butted face end. CONSTITUTION:Magnetic heads 20a, 20b are fitted to a rotary drum so that a notch 31 comes to an exit of a running tape 32 in the running direction. Since an upper end 25a of a magnetic gap 26 is a bottom of a V-shaped recess 28, a comparatively strong leakage magnetic field is generated and a leakage is cased at one side T-1a of a recording track T-1 so as to may cause a possibility of spreading the pattern, but a magnetic head 20 recording a recording track T-2 adjacent to the recording track T-1 applies overlapped recording to cancel the leakage by using a low end 26b of the magnetic gap 26, then the leakage is eliminated. Since the wall face 31a near the lower end 26b is constituted nearly perpendicularly to the magnetic gap 26, the leakage magnetic field is decreased.

Title: Mh code signal decoding system
Inventor: YAMAZAKI NAOKI
IPC: H04N1/419
Filed: 1987-02-20
Abstract: PURPOSE:To prevent a coding error due to the coding of an MH code signal generated from a point on the way of a scanning line by outputting only a pattern data converted from an MH code signal as a valid image pattern signal after a scanning line start signal is detected from said inputted MH code signal. CONSTITUTION:If a scanning line start signal detection circuit 3 detects a scanning line start signal and the signal is latched by a latch circuit 4, an AND circuit 5 supplies an enable signal from an enable signal generation means 2 to a gate 6, so that a pattern data decoded by a pattern conversion ROM 1 is transmitted to a device in the following devices, and thus the pattern is made a valid one. Such a pattern data thus made valid is a data only after the arrival of a scanning line start signal, i.e., a data from the beginning of each scanning line. In such a way, an erroneous detection due to lock of the number of picture elements caused by starting the decoding an MH code signal corresponding to an interim point on a scanning line, can be prevented.

Abstract: PURPOSE:To improve the efficiency between pattern zones and letter zones corresponding to the pattern zones by setting the letter zones corresponding to the pattern zones in negative zones based on the set negative zones and the pattern zones set in the negative zones. CONSTITUTION:Negative zones representing the limits within which pattern zones and letter zones can be laid out by an input device 3. Similarly the desired number of pattern zones in which photographs are shown is set in the negative zones set preliminarily by a mouth 3B or a kayboard 3A working as the input device 3. Based on the respective zone data set as above, letter zones D-F for the commodity specification are formed automatically. The letter zones D-F are set respectively on the lower side of pattern zones A-C in a manner of following the respective pattern zones A-C. Thus the letter zones corresponding to the pattern zones can be laid out securely in empty zones in the negative zones after laying out the pattern zones in the negative zones.

Title: Conveyor for change-direction and alignment of article to be conveyed
Inventor: INOUE MITSUYOSHI
IPC: B65G47/31
Filed: 1986-02-20
Abstract: PURPOSE:To perform the change-direction and arbitrary equal space alignment of articles to be conveyed, by providing, in series, main and auxiliary belt conveyors rectangular to a supply conveyor in such a manner that said conveyors can be performed in speed bariable adjustments respectively. CONSTITUTION:Articles 40 are conveyed by a supply conveyor and transferred on a roller conveyor 6 at the end thereof. Then, at the time when the articles 40 are sensed by a sensing switch 39, the clutch of a speed reducer 27 is meshed so that cam shafts 28, 42 are turned by one revolution respectively. Thereby, main and auxiliary belt conveyors 16, 19 are intermittently shifted by one pitch at the same time, respectively. At this time, since the shifting speed of the auxiliary belt conveyor 19 is earlier than that of the main belt conveyor 16, the shifted pitch becomes larger in the auxiliary belt conveyor 19. And, on shifting, the auxiliary belt conveyor 19 is performed in turning motion slightly upwards around a common driven shaft 9 of both conveyors. Therefore, even if the articles are conveyed by the supply conveyor in an irregular condition, the main and auxiliary belt conveyors are driven only at the time when the articles are sensed by the sensing switch, thereby it is possible to perform the change-direction to a right angle and intermittent alignment of the material.
