Title: Input device for color picture
Inventor: HIROTA YOSHIHIKO
IPC: H04N1/46
Filed: 1987-05-21
Abstract: PURPOSE:To simplify a circuit constitution by reading white reference patterns provided beyond an original picture scanning area before the original picture is scanned, calculating the mean value and executing shading correction at every color with the mean value as reference data. CONSTITUTION:The white reference patterns which have been provided beyond the original picture scanning area and the white reference patterns are read before the original picture is scanned and the prescribed mean value of plural chrominance signals in the white reference patterns are calculated. The mean value is stored in a storage means 201 as reference data SH-DATA0-5 of shading correction in color resolution data. By using reference data SH-DATA0-5 which have been stored in the storage means 201, the operation of shading correction is executed with respect to data of respective colors. Thus, shading correction is executed with the simple constitution.

Title: Loudspeaker system
Inventor: YAMAMOTO MAKOTO
IPC: H04R5/02
Filed: 1981-08-13
Abstract: PURPOSE:To obtain the whole directivity even if a woofer enclosure is brought close to the wall surface, by placing a woofer enclosure, and intermediate and high band loudspeakers in the circumference, combining them with the woofer enclosure, or constituting it of plural socrker and tweeter enclosures. CONSTITUTION:Even when a woofer enclosure 8 of a system 7 is placed so as to make it tightly adhere to a wall surface 15, scoker and tweeter enclosures 9, 10 having the whole directivity are kept to hold distances of D2 and D3 from the wall surface 15, respectively. Acoustic waves A1, A4 of scorkers 13b1, 13b4 are radiated directly, and acoustic waves A2, A3 of scorkers 13b2, 13b3 become a reflected sound from the wall surface 15. In case of a tweeter, too, said constitution is all the same. Accordingly, acoustic waves of the scorkers 13b2, 13b3 and tweeters 14b, 14c reach an audible position effectively as a reflected sound, and the whole directivity of the system 7 is displayed. An acoustic wave of a scorker 13a having narrow directivity is radiated to the front, and an acoustic wave of a woofer 12 is reflected since it has a distance D1 to a floor 11, and displays the whole directivity.

Title: Electronic musical instrument
Inventor: NAKANISHI SHOJI
IPC: G10H1/36
Filed: 1989-05-19
Abstract: PURPOSE:To easily play (or automatically play) music on the way of which automatic accompaniment is started by providing a means which controls the sound volume/sound production of automatic accompaniment in accordance with the timing of the start of a detected measure. CONSTITUTION:At the time of automatically playing music on the way of which automatic accompaniment is started, a player turns on a start switch 16 at an arbitrary timing during playing to send data of automatic accompaniment to a sound producing circuit 19, and simultaneously, the sound producing circuit 19 is controlled by a sound production control circuit 22 to mute automatic accompaniment to be played. When a measure start detecting circuit 21 first detects the start of the measure of automatic accompaniment by a clock signal thereafter, the sound production control circuit 22 releases the data control to the sound producing circuit 19. Therefore, sound production of automatic accompaniment can be started without being deviated from automatic playing. Thus, automatic accompaniment is smoothly started on the way of music by the easy operation.

Title: Mass flow meter
Inventor: ITO ICHIZO
IPC: G01F1/32
Filed: 1990-05-17
Abstract: PURPOSE:To obtain a mass flow rate signal from which the influence of a low frequency noise is eliminated by inputting an eddy flow rate signal to a BPF with a low-cut frequency in which a high-cut frequency is selected less than the eddy frequency of an eddy signal to be measured. CONSTITUTION:A temperature correction circuit TCC outputs detecting sensitivity i.e. the temperature change of a piezoelectric constant for the temperature of piezoelectric elements 17, 18 to a voltage signal e 1. An eddy generated by the flow velocity of fluid to be measured is converted to the eddy signal e 2 by an eddy signal conversion circuit. Also, the eddy signal e 2 is inputted to the BPF, and is signal-processed, however, the high-cut frequency of the BPF is selected less than the eddy frequency of the eddy signal e 2 to be measured in the eddy signal e 2, and it is set as output in accordance with a mass flow rate. Furthermore, the low frequency noise superimposed on the eddy signal e 2 and inputted can be reduced by changing the low-cut frequency of the BPF corresponding to the eddy frequency of the eddy signal e 2 by a low-cut frequency change signal.

Title: Radar transponder
Inventor: KAWAKAMI YOICHI
IPC: G01S7/28
Filed: 1995-05-26
Abstract: PURPOSE: To prevent the erroneous response due to the influence of a transmitter side and to be able to stably operate for an infinitesimal signal by providing a single-pole double-thrown switch connected to a receiver side in case of receiving and at the ground side in case of transmitting as seen from a switching unit. CONSTITUTION: The radar signal received by a transmission and reception shared antenna 1 is passed through a circulator 2 (switching unit) and an RF switch (single-pole double-throw switch) 10, amplified by an FET amplifier 3, then transmitted to a diode-direct detector 4, and a response radio wave is radiated from the antenna 1. In a receiving state, a transmitting gate 8 is not opened, a switch drive signal to the switch 10 is off-state, and PIN diodes 11a, 11b are opened, and hence the radar signal is passed from the input side to the output side. When it becomes the transmitting state and the gate 8 is opened, the drive signal to the switch 10 becomes on-state, and the diodes 11a, 11b are short-circuited. That is, the diode 11b becomes a ground potential, and the transmission leakage radio wave fed to the input side is absorbed by a matching line 14.

Title: G-k differential drive type video output circuit

Filed: 1988-05-27
Abstract: PURPOSE:To prevent saturation of a G1 drive transistor(TR) in G1-K differential drive system by operating a saturation preventing diode means through a detected output from a current detecting means so as to limit an output current of a grid drive means. CONSTITUTION:If a current flowing to resistor 11 is going to exceeds 130mA, a collector potential of an output TR 10 is going to enter the saturation region of 15V or below and a potential of 1.3V is generated across a current sensing resistor 14. In this case, a cathode potential of a diode 15 is nearly 0.6V and the diode 15 starts conduction. Then a voltage drop is generated across a resistor 16, which acts to prevent the base potential of an emitter follower 13 from being decreased more. Thus, the excess decrease in the potential of the emitter follower 13 is prevented and excess increase in the collector current of the output TR 10 is prevented and the saturation of the output TR 10 is avoided.

Abstract: PURPOSE:To eliminate the need for the exchange of nozzles every time the width of a drawing line changes, to improve productivity and to reduce cost by installing a rotary drive section turning the nozzle, the inside of which houses paste and a nose of which has a slit hole from which paste is discharged, so as to be directed in the arbitrary direction to the progressive direction. CONSTITUTION:A servomotor 4 is turned so that the direction of drawing, the direction of the relative displacement of a nozzle 1, and the direction A, the direction rectangular to the longitudinal direction of a slit hole 1a for the nozzle, coincide at all times in movement in each direction of two X-Y directions, revolution is transmitted by a pulley 8, a belt 7 and a pulley 5 and the nozzle 1 is rotated when drawing operation is conducted, thus resulting in drawing width W0 the same as width in the longitudinal direction of the slit hole 1a. When revolution at an angle theta is performed in such drawing operation, drawing width W1 is used as the function of the angle theta. W1=W0Xf(theta) holds. Accordingly, the nozzle 1 is revolved by the servomotor 4 so as to change the direction of the slit hole 1a for the nozzle 1 in the direction of drawing, thus altering drawing width within a wide range.
