Title: Information setting device
Inventor: GOTO TETSURO
IPC: G03B7/00
Filed: 1996-01-05
Abstract: PROBLEM TO BE SOLVED: To improve the deterioration of operability occurring because a movable area such as a thumb differs between in an up-and-down direction and a right-and-left direction by making the detecting resolution of manipulated variable in the up-and-down direction and the right-and-left direction differ. SOLUTION: Two rollers 40A and 40B come in contact with the side surface of a track ball 10. The rollers 40A and 40B are interlocked with the rotation of the track ball 10 in the up-and-down direction 11 and the right-and-left direction 12. Sectors 41 and 42 are fixed at one-side ends of the rollers 40A and 40B and rotated with the rollers 40A and 40B interlocked with the track ball 10. Slits are engraved on the outer periphery of the sectors 41 and 42. The pitches of the respective slits are different, and the pitch of the slit on the sector 42 is made smaller. Thus, in the up-and-down direction 11 where rotational amount is small, much pulse output is generated even by very small rotational amount. The passage of the slit is detected by photocouplers 43A and 43B provided near the sectors 41 and 42. Thus, the deterioration of the operability caused by the effect that the movable area is different between the direction 11 and the direction 12 is improved.

Title: Ink jet recording head and manufacture of its vibrating plate
Inventor: NAKAMURA TAKASHI
IPC: B41J2/16
Filed: 1995-01-09
Abstract: PURPOSE: To eliminate the pinhole of a vibrating plate at all and to improve the durability by forming a vibrating plate by connecting an island part formed by etching a metal thin plate to a polymer oriented film with an adhesive. CONSTITUTION: A vibrating plate 7 is formed by etching a metal thin plate 20 laminated on the surface of a polymer oriented film 8 via an adhesive 21. The plate 7 has an island part 9 extended in the longitudinal direction of a pressure generating chamber, and displaced by a piezoelectric vibrator via the island 9. Since the island 9 is fixed to the film 8 via the layer of the adhesive 21, a stress at the end of the island part 9 is diffused by the adhesive 21, a stress concentration at the film is not only alleviated, but also the adhesive 21 of the surface becomes one type of the sealing material, and even if the film 8 is damaged or a defect exists, ink leakage can be prevented.

Title: Developing method of electrostatic latent image
Inventor: TABUCHI KENJI
IPC: G03G13/09
Filed: 1982-02-05
Abstract: PURPOSE:To obtain a uniform picture having no developing unevenness even if a magnetic roll is rotated at a low speed by equalizing the pitch of each developing unevenness and shifting the phase of the developing unevenness in case of developing an electrostatic latent image plural times. CONSTITUTION:Although the electrostatic latent image of a beltlike photorecepter 1 is developed by developing rolls 2, 3, developing unevenness may be generated when the number of revolutions of magnetic rolls 5, 5' are reduced. In order to equalize the pitch of unevenness, the magnetic rolls 5, 5' are constituted by eight poles, the number of revolutions is set to 900rps and the frequency of an alternating field is uniformed. In addition, the length L between the rolls 2 and 3 is set up to the prescribed length and the phase of the developing unevenness is shifted by pi/2. Even if the number of revolutions of the magnetic rollers are reduced, the 1st and 2nd developing unevenness are interfered with each other and compensated and a uniform picture having no developing unevenness can be finally obtained, preventing bad influence due to high-speed rotation of the magnetic rolls.

IPC: G01R15/00
Filed: 1995-02-06
Abstract: PURPOSE: To notify a user that the sensitivity adjustment has been changed and to prevent false measurement by providing a switching means for selecting either a voltage signal for detecting the amount of displacement or a reference voltage signal. CONSTITUTION: An AC voltage is applied from an excitation part 30 to the primary coil of a differential transformer 10 and the amount of displacement of an object to be measured is converted to a voltage signal by the transformer 10. The voltage signal is outputted to an operation amplification part (for measurement) 12 and an operation amplification part (for detecting sensitivity change) 14 from output terminals A and B. A voltage signal (VA+VB) becomes an AC voltage with a constant amplitude regardless of the amount of displacement of the object to be measured and a voltage (reference voltage) with a constant amplitude is outputted from an amplification part 14.  An input signal switching part (switching means) 16 selects either of voltage signals from amplification parts 12 and 14 based on a control signal from a control part 24 and outputs it to a detection rectification part 18. The control part 24 compares the output value of the amplification part 14 with a value at the time of starting the measurement and shows a warning on a display 28 when there is at least a specific change.

Title: Carrier wave reproducing circuit
Inventor: NAKAJIMA MASAHIRO
IPC: H03J7/02
Filed: 1982-02-05
Abstract: PURPOSE:To attain sure carrier wave pulling-in even at the initial state, by  inserting a limiter circuit limiting an AFC circuit output signal between an output of the AFC circuit and an input of a voltage controlled oscillator. CONSTITUTION:The frequency difference between the oscillating frequency of the voltage controlled oscillator VCO8 and the carrier wave signal is detected at phase detection circuits 1, 5; a high frequency component is rejected at LPFs 2, 6, and the synchronism of the reference carrier wave is established with a base band processing circuit 3. An AFC circuit 4 detects the frequency difference component between the input carrier wave signal frequency and the oscillating frequency of the VCO8, controls the VCO8 with the DC component and applies AFC. When the linearity of the AFC circuit characteristics is extended, the oscillation frequency of the VCO8 reaches a region where no AFC voltage appears at the initial state such as power supply application and the synchronism of carrier wave is not established permanently. In connecting a limiter circuit 9 to the output of the circuit 4, however, the oscillating frequency of the VCO8 is fixed to a range where the AFC voltage appears even at the initial state.
