Title: Copying machine with image enlarging and contracting function capable of continuous variable magnification
Inventor: OGAWA RIYOUTA
IPC: G03B27/34
Filed: 1981-09-24
Abstract: PURPOSE:To obtain a variable magnification copying machine of simplified structure which has a continuous image enlarging and contracting function at a low cost, by successively shifting the scan starting position of a half-speed mirror and a lens position according to magnification with use of a single-focus lens consisting of less lens elements as a substitute for a zoom lens system. CONSTITUTION:A half-speed mirror moving mechanism is added to a conventional mirror scanning mechanism, and the scan starting positions of half-speed mirrors M2 and M3 are shifted by LAMBDALm/2 according to varied magnification by using a known position-restricting numerical control motor, e.g. a stepping motor. Then when the scan starting positions of the mirrors M2 and M3 are shifted to desired magnification positions, a driving pulley 5a is disabled to rotate by using an electromagnetic brake 14 so that a full-speed mirror M1 does not move, and then a photointerrupter 15 detects whether the half-speed mirrors M2 and M3 are at the scan starting positions in unmagnification copying mode to transmit pulses, whose number corresponds to the shift LAMBDALm/2 of movement. Thus, a feed screw 9 is rotated to allow the half-speed mirrors M2 and M3 to move by LAMBDALm/2 and then stop.

IPC: G10K15/12
Filed: 1994-06-09
Abstract: PURPOSE:To generate diverse sound effect which are rich in variation. CONSTITUTION:An input signal is inputted to a positive half-wave detecting circuit 1 and a negative half-wave detecting circuit 2. The signal is divided by those circuits 1 and 2 into a positive half wave and a negative half wave.

Filed: 1990-06-12
Abstract: PURPOSE:To use a light paper or plastic cup by detecting the presence of a cup on a pan, operating an actuator, and pressing down the pan to water injection starting position for a fixed time. CONSTITUTION:A reflective coating material is applied to the surface of a cup 10, or a reflec tive tape is wound thereon, as occasion demands. When the cup 10 is put on a pan 11, the light continually emitted from the light emitting diode of an optical sensor 21 is reflected by the cup 10 and entered into the photo transistor of the optical sensor 21, whereby an actuator 22 is operated to lower the pan 11 to water injection starting position for a fixed time. Then, a push rod 18 pushes down the spool 33 of a water injection control means 30 against a spring 37 supporting the spool 33 to allow a first chamber 31 to communicate with a second chamber 32. Consequently, the pressure air contained in the first chamber 31 through an inlet port 34 from an air pressure source 38 enters the second chamber 32 and reaches an opening and closing valve 16 through a pipe 36 from an outlet port 35, and the opening and closing valve 16 is opened to continue the water injection to the cup 10 for a fixed time. When a determined amount of water is injected into the cup 10, the pan 11 is further lowered to water injection stopping position by its weight, and the push rod 18 pushes the spool 33 of the water injection control means 30 onto the bottom surface of the second chamber 32 to seal the outlet port 35, and the injection from an injection pipe 15 is stopped.

Title: Matching system for balanced connection network
Inventor: HAYASHI KIYOBUMI
IPC: H04B3/03
Filed: 1981-09-25
Abstract: PURPOSE:To always ensure the matching and to improve the speech quality, by providing plural balanced connection circuit networks and then selecting optimum one of these circuit networks. CONSTITUTION:A call current is supplied to a telephone from a DC power supply 34 via a feeding circuit 33 and a double wire line. The voltage which is generated between terminals 71 and 72 of the double wire line by the call current is detected by a voltage detector 37. The level of the detected voltage Vi is decided by comparators 38-1-38-n. Based on this result of decision, the optimum one is selected among balanced connection circuit networks 32-1-32-n by a selector 39. In such a wat, the voltage generated between the terminals 71 and 72 by a call current varies in response to the change of the resistance at the double wire that is due to the change of the type and length of the double wire line. Accordingly a balanced connection circuit network that is best matched with the resistance of the double wire side is selected. Thus the degree of unmatched attenuation can be kept large enough for a hybrid transforming circuit 31. Then the speech quality is improved.

Filed: 1989-06-14
Abstract: PURPOSE:To improve the S/N of a reproducing signal and to attain miniaturization and light weight by utilizing the fact that the diffraction effect of a concave diffraction grating is provided with deflection dependency, and arranging the convergence part of the concave diffraction grating and every constitutional part on a Rowland circle. CONSTITUTION:Monochromatic light having linear polarizing characteristic from a monochromatic light source 21 is guided to the concave diffraction grating 23, and is image-formed on the recording plane of an optical disk D as a light source image with the grating 23. Since radiant light from the light source 21 is P-polarized light against the grating 23, an S-polarized light component is generated by the rotation of a polarizing plane by a Kerr effect. Then, the S-polarized light component goes to the reproducing signal corresponding to recording information. Thus, when reflected light including the P- and S-polarized light components is guided to the grating 23, the S-polarized light component is reflected as nth-order diffracted light with the grating, and is guided to a reproducing detector 24. The P-polarized light component is reflected as mth-order diffracted light with the grating 23, and is guided to an error signal detector 25. And since the focal points and the recording planes of the detector 24 and 25 are arranged on the Rowland circle C of the grating 23, the light can be image-formed on a focal point plane.
