Title: String instrument
Inventor: DEJIMA TATSUYA
IPC: G10H3/00
Filed: 1994-05-30
Abstract: PURPOSE:To provide a string instrument in which a second parts group easily affected by the vibration of a value added device is made immune to the effect of string vibration in playing. CONSTITUTION:The first parts group of a string vibration system such as a neck 6 and a bridge base plate 17, etc., is mounted on the lower case 2 of an instrument main body via a reinforcing plate 5, and a circuit board 26 provided with a tape recorder main body 23 and an effect function, and the second parts group of the value added device for a speaker 20, etc., are mounted on the upper case 3 of the instrument main body, and the lower case 2 and the upper case 3 are mounted integrally by interposing a vibration absorbing member 30 between the upper terminal part of the side wall 2b of the lower case 2 and the lower terminal part of the side wall 3b of the upper case 3. Therefore, the string vibration of the first parts group is absorbed in the vibration absorbing member 30 even when it is transmitted to the lower case 2 in the playing, which makes the string vibration hard to transmit to the second parts group via the upper case 3, and prevents the second parts group from receiving the effect of the string vibration, and stably operates the value added device such as the tape recorder main body 23, etc.

Title: Driving method of optical modulating element
Inventor: KANBE JUNICHIRO
IPC: G09G3/36
Filed: 1983-07-30
Abstract: PURPOSE:To avoid a drop of a picture contrast and a crosstalk by applying a voltage which has set a threshold voltage of an optical mudulating substance having a bistability to a specified value. CONSTITUTION:When a threshold voltage for giving the first stable stage of a liquid crystal cell having a bistability, and a threshold voltage for giving the second stable state are denoted as Vth1 and -Vth2, respectively, a voltage 2V exceeding the threshold Vth1 is applied to a picture element A on a selected scanning line, and a voltage -2V exceeding the threshold -Vth2 is applied to a picture element B existing on the same scanning line. On the other hand, on a scanning line which is not selected, a voltage applied to all picture elements C and D is +V or -V, and both of them do not exceed the threshold voltage. Accordingly, a liquid crystal molecule in each picture element of C and D holds an orientation as it is corresponding to a signal state in case of the previous scanning without changing the oriented state. Accordingly, even if the number of scanning electrodes is increased, a substantial duty ratio is not changed, and a drop of a contrast, a crosstalk, etc. are not generated at all.

Title: Sound field control device
Inventor: KOWAKI HIROSHI
IPC: G10K15/12
Filed: 1997-05-28
Abstract: PROBLEM TO BE SOLVED: To provide a sound field control device which can always generate an appropriate acoustic signal regardless of the kinds of sound sources. SOLUTION: This device 5 is constituted so that inputted left and right audio signals are processed and acoustic signals necessary for a sound field control are generated. In this case, a delay means 6 delays one of the left and right audio signals L and R. An addition or subtraction means (8 and 9) add or subtract an output signal from this delay means 6 to/from other signal of the left and right audio signals. A generation means 7 generates an acoustic signal on the basis of the outputted signal from this addition or subtraction means. According to this device, since one of the left and right audio signals is delayed, a correlation between the left and right audio signals is reduced and an acoustic signals is generated even when the correlation is high as in a vocal. Thus, a particular sound does not have an acoustic effect and a natural sound is obtained.

IPC: H01L31/107
Filed: 1980-10-04
Abstract: PURPOSE:To avoid the occurrence of an edge breakdown, by using a photodiode constructed with a compound semiconductor layer. CONSTITUTION:An N type InP layer 22 having a larger band gap than the energy band gap Eg1 of an InGaAs layer 21 is formed on said InGaAs layer 21 having carrier concentration of 10<15>-10<16>/cm<3>.

Title: Automatic focus adjuster
Inventor: KAYANO YASUAKI
IPC: G03B13/36
Filed: 1989-06-02
Abstract: PURPOSE:To preclude the malfunction of automatic focus adjustment due to random noise by securely detecting direction data being affected by the random noise in an out-of-focus state. CONSTITUTION:When the specific previously set number of direction data which indicates the same direction are generated in an out-of-focus state, a control signal which sets the direction to the moving direction of a focus lens is generated and in the out-of-focus state, the control signal is inhibited from being generated. In an in-focus state, it is decided whether focusing/defocusing data indicating defocusing is real focusing/defocusing data or false focusing/defocusing data due to random noise. Only when the focusing/defocusing data is the real data, the control signal is generated if successive direction data less than the specific number indicates the same direction, thereby detecting the direction data being affected by the random noise. Consequently, malfunction in the in-focus and out-of-focus states due to the external random noise is precluded completely.

The 19kHz pilot signal leaked to the demodulation signal is attenuated or eliminated from L and R channel demodulation signals outputted from an L output terminal 16 and an R output terminal 17 at the digital filters 24, 25.

Title: Method for recovering zinc in dust
Inventor: SAKAMOTO NOBORU
IPC: C22B7/02
Filed: 1993-05-18
Abstract: PURPOSE:To recover the zinc in zinc-contg. dust at a high concn. by coating the green pellets formed by adding a carbonaceous reducing agent to the dust and pelletizing the dust with powder coke and baking the dust with an endless moving grade type sintering machine, thereby evaporating the zinc. CONSTITUTION:The carbonaceous reducing agent is added at 5 to 20wt.%, a pelletization accelerator at 5 to 25% and a bonding accelerator at 2 to 15% to the zinc-contg. dust and the dust is pelletized into the green pellets having 3 to 15mm grain sizes. The green pellets are coated with 0.2 to 5% powder coke. The coated green pellets are supplied to the endless grade type sintering machine and are baked. A strong reducing atmosphere is generated in the green pellets in the first period of the baking to reduce and evaporate the zinc oxide in the mixture and to form the gaseous metal zinc. This metal zinc is oxidized in waste combustion gases of a lowered temp. to powdery zinc oxide which is recovered together with the dust in waste gases by a dust collector. The baked agglomerate having an excellent reducing property is produced at a high yield by this treatment.
