Title: Sound source integrated circuit with built-in effect adding device
Inventor: KANEKO YOJI
IPC: G10H1/00
Filed: 1992-04-07
Abstract: PURPOSE:To enable effect addition processing of high quality without using a dedicated DSP chip when a system is constituted by using sound source LSIs of plural chips including the sound source LSIs having DSP for effect addition inside. CONSTITUTION:In the master and slave sound source LSIs 104 and 105, time- vision musical 6ound signals from a musical sound signal generator are divided into four different groups, channel by channel, weighted with mutually different coefficients, and accumulated. Four kind of accumulation outputs obtained by the master sound source LSI 105 are transferred to the slave sound source LSI 104, which adds them to the respective accumulation outputs obtained by itself. The addition results are transferred to the master sound source LSI 105 after the effect addition processing is performed by the DSP of the slave sound source LSI 105, and effect is further added by the DSP of the master sound source LSI. Its output is outputted to a D/A converter 108.

Abstract: PURPOSE:To obtain a device dispensing with machining of a slit by a method wherein a slit being substantially parallel to a rotating shaft is formed by a rotary body fitting eccentrically to the rotating shaft and a restricting plate disposed separately from the rotary body. CONSTITUTION:A slit 4 being parallel to a rotating shaft 2 is formed between a rotary body 1 fitted eccentrically to the rotating shaft 2 and a restricting plate 3.

Since the light-emitting element 6 is constituted by a semiconductor laser 5, the wavelength of the light emitting therefrom is fixed, and only the width of the slit 4 is varied with the rotation of the rotary body 1. A photodiode 8 of a light-receiving element 9 is disposed at a position deviated from the optical axis of the laser 5 of the light-emitting element 6, and the intensity of the received light is varied in accordance with the rotational angle of the rotary body 1. The output of said diode 8 is subjected to wave shaping, and a pulse obtained thereby can be used for control and measurement.

Abstract: PURPOSE:To widen a visual angle by providing an area in which an orientation vector is different, on the same substrate. CONSTITUTION:A figure (a) shows an electrode pattern of a liquid crystal display element, and a figure (b) shows an orientation vector of two upper and lower glass substrates and an optimum visual angle direction. Also, a transfer 8 for connecting the two upper and lower glass substrates, Y axis electrodes Y1- Yk and X axis electrodes X1-Xk are provided. A visual angle is different since the orientation vector of the glass substrate is different in the upper side and the lower side of the drawing, therefore, in case the same display pattern is formed in the upper side and the lower side of the drawing, the visual angle is increased to two times as a result. In this regard, as for a method for making the glass substrate have the orientation vector, a rubbing method and a diagonal vapor-depositing method are available, but in this case, the diagonal vapor-depositing method is suitable in order to clarify a boundary of an area in which the orientation vector is different.

Abstract: PURPOSE:To measure with good reproducibility the high-concn. salinity in crude oil measurement of which is impossible so far by regulating the water content in a reference sample which is used for measuring salinity in crude oil within a specified range wider than the ASTM method. CONSTITUTION:Neutral oil (lubricating oil is used), xylene, a mixed alcohol soln. (a mixed liquid having 610:360:40 volume ratio of butanol:methanol:distilled water), and an aq. soln. of salts (contg. respective specified amt. and concn. of CaCl2, MgCl2, and NaCl) are mixed to prepare a reference sample whose water content is regulated to 2.0-3.0vol%. A calibration line shown in the figure is formed by measuring the electroconductivity of the referece sample. A test sample is prepared by using crude oil to be measured instead of the neutral oil and adding the mixed alcohol having same volume as the total volume of the aq. soln. not contg. the above-mentioned three kinds of salts and the mixed alcohol instead of the two components. The electroconductivity of the test sample is obtained. By comparing the obtained electroconductivity with said calibration line, the high-concn. salinity in the crude oil can be measured simply in the range of 500-5,000mg/l.

Title: Card transfer device

Filed: 1990-03-30
Abstract: PURPOSE:To obtain a card transfer device capable of easily shifting a transfer position toward the width direction of a card by moving a support shaft and then moving a heat roller mounted to the support shaft via a supporting member in a direction orthogonal to the direction in which the card is fed. CONSTITUTION:The shift of a transfer position toward a direction in which a card 19 is fed is done in such a way that the relation between the rotation of a heat roller 8 and the feed of the card 19 is changed by loosening a screw 17 and changing the relative positional relation between a protruding piece 15a and a sensor 16 and that a position where a transfer protruding part 8a contacts the card 19 under pressure is moved in the longitudinal direction of the card 19. Then, the shift of the transfer position toward the width direction of the card 19 is done by loosening a screw 6 to displace vertically the mounting position of a support shaft 4. That is, the shift is done by displacing vertically the heat roller 8 supported to the support shaft 4 via a supporting member 7 to move the position where the transfer protruding part 8a contacts the card under pressure toward the transversal direction of the card 19. Thus, the shift of the transfer position toward the width direction of the card 19 can be done without replacing the heat roller.

Abstract: PURPOSE:To prevent the damage of a charge electrode due to a short-circuit generated over a long time or many times by outputting detection data to an alarm device, an electrode charging means and the ink supply means of a nozzle when a detection means detects the short-circuit of the nozzle and the electrode. CONSTITUTION:A short-circuit detection part 17 as a detection means is connected to an FET 13 in parallel and constituted of a DC cutting condenser 18, a low-pass filter 19, an amplifier 20 and an LED. When the charged electrode 5 after passed through a switch element driving part 10 and a nozzle 3 are short-circuited by the ink bonded to the charged electrode 5, the output of a DC voltage variable part 9 is subjected to low frequency oscillation between 100 volt at the beginning and O volt and, when this phenomenon is detected, the short-circuited state can be shown to the outside and early protection becomes possible. Since the short-circuit of the charged electrode 5 and the nozzle 3 is informed to the outside by allowing the LED 21 to emit light by the detection part 17, the damage of the charged electrode 5 due to a short- circuit over a long time or many times can be prevented.
