Title: Stereoscopic display device
Inventor: HANDA SHIYUNJI
IPC: H04N13/04
Filed: 1980-11-10
Abstract: PURPOSE:To suppress the flickering of display images by forming display elements of strong viewing angle dependency having viewing angles in different directions into two layers. CONSTITUTION:A display element 1 shows extremely strong display contrast in the direction of 3 and its display is invisible despite the observation from the directions other than this. A display element 2 shows extremely strong contrast in the direction of 4, and its display is invisible despite the observation from the direction other than this. The directions of 3 and 4 are respectively the direction where there is the right eye of an observer and the direction where there is his left eye. This results in that the observer is viewing an actual object, thus he is able to observe a natural stereoscopic image free from longitudinal stripes and flickering.

Title: Key driving device
Inventor: MURATA YOSHIYUKI
IPC: G10F1/02
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To provide a key driving device which ensures smooth key touch operation according to the respective characteristics of the different key touch operations even if either operation of the manual key touch operation and the automatic key touch operation is carried out. SOLUTION: A turning lever 21 turns clockwise cooperatively with the suction of a plunger 17 when the plunger is sucked in the rear end direction of a key by energizing a solenoid 18 at the time of the automatic key touch operation for automatic playing. A pin 5 engaged with the curved part at the other end of the turning level 21 is then pulled in a perpendicular direction and, therefore, a white key 2a is driven downward in a depressing direction. The other end of the turning lever 21 with which the pin 5 is engaged is designed not to restrain the downward movement of the pin 5 and, therefore, if the white key 2a is manually depressed, the white key is pushed down to the prescribed key touch depth without being hindered by the turning lever 21 at all at the time of the manual key touch operation for manual playing.  A rubber switch part 3B is pushed by the touched key 2a even in the case of either operation of the manual key touch operation and the automatic key touch operation and, therefore, the musical tone of the corresponding pitch is generated in response therewith.

Title: Data signal decoding device
Inventor: TAKAYAMA MICHIO
IPC: H03M5/04
Filed: 1981-10-06
Abstract: PURPOSE:To eliminate the need to modify the constitution of a circuit even in case of the change of a signal speed and variation in the character length of a start-stop signal, by using a character timer which generates a signal with time width which is an integral multiple of the character length. CONSTITUTION:A data signal inputted to a terminal 1 is supplied to a decoding circuit 103 and a polarity monitoring circuit 100. A character timer uses clock pulses which regard the character length of a start-stop signal as unit time, and thus generates a signal with time width which is an integral multiple of the character length, thereby supplying the generated signal to the circuit 100. The circuit 100 sets the decoding mode of the start-stop signal when deciding that the input signal is a high-level successive signal, the decoding mode of a different kind of DC signal when deciding that it is a low-level successive signal, or the decoding mode for holding the past decision mode when the input signal is not successive, thereby performing transmission to the decoding circuit 103.

Title: Electrostrictive vibrator electrode for ink jet head
Inventor: ISAYAMA TAKUO
IPC: B41J2/055
Filed: 1985-07-19
Abstract: PURPOSE:To compensate for scattering of jetting characteristics among nozzles and eliminate the need to individually control driving pulse waveforms, pulse voltage or the like, by dividing an electrode for an electrostrictive vibrator in an ink jet head into a main electrode and at least one auxiliary electrode, and selectively connecting the auxiliary electrodes. CONSTITUTION:The electrode 6 for the electrostrictive vibrator is divided into the main electrode 21 and the auxiliary electrodes 22, 23, and the auxiliary electrodes 22, 23 are used or unused in addition to the main electrode 21, whereby the effective area of the electrode 6 is regulated. The scattering of characteristics among nozzles is compensated for by regulating the effective area of the electrode 6. The quantity of strain generated in the electrode 6 is varied with the effective area, under the same applied voltage. Therefore, when the effective area of the electrode 6 is varied according to the jetting characteristic of the nozzle, for example, the magnitude of the jetting velocity of droplets, the scattering of the jetting characteristics (jetting velocity of droplets) among the nozzles can be uniformized to within the allowable scattering.

Title: Production of high magnetic permeability ferrite material
Inventor: KOZUKA YOSHINARI
IPC: C30B29/22
Filed: 1987-06-27
Abstract: PURPOSE:To advantageously obtain the title ferrite material having high magnetic permeability in the high-frequency region by joining a polycrystal ferrite member and a single-crystal ferrite member having a thermal expansion coefficient different from that of the former member, and heating the joined material. CONSTITUTION:The polycrystal ferrite member and the single-crystal ferrite member having a thermal expansion coefficient different from that of the polycrystal ferrite member are joined, and heated to form the polycrystal ferrite member into a single crystal. As the difference in the thermal expansion coefficient between the polycrystal ferrite member and the single-crystal ferrite member is increased, more internal strains are imparted to the single-crystal ferrite. When the difference is excessively increased, cracks are generated in both members, and the permeability is also lowered. Accordingly, both members are selected so that the difference DELTAalpha between the thermal expansion coefficients alphameasured at 40-1,000 deg.C is controlled to <10X10<-7>/ deg.C.

Title: Paper feed device
Inventor: NAGAI TOMIO
IPC: B65H3/52
Filed: 1988-06-30
Abstract: PURPOSE:To feed plural paper sheets always one by one in sequence to a paper feed goal by providing a separator roller freely rotatable only in the opposite direction to the rotation of a paper feed roller in the paper feed direction. CONSTITUTION:When paper sheets 12 are fed in piles, a signal which shows this status is inputted into a control part 31 through a sensor 25. When this signal is inputted, a hopper 11 is brought down through a motor 10 and paper feed rollers 13, 14 and a conveyer roller 22 are reversely rotated through motors 18, 24 by the control part 31. Thus, the paper sheet 12 passes between the paper feed roller 14 and a separator roller 15 and is reversely conveyed to the hopper 11 side. In this case, the separator roller 15 brought in press-contact with the paper feed roller 14 does not obstruct the return back of the paper sheet 12 to the hopper side 11 because the separator roller 15 can be rotated freely only in the opposite direction to the rotation in the paper feed direction of the paper feed roller 14. Also meantime, the paper sheet 12 reversely conveyed to the hopper 11 side does not accept the conveying force of the paper feed roller 13 reversely rotated because the hopper 11 is brought down.
