IPC: G11B20/24
Filed: 1989-12-29
Abstract: PURPOSE:To reduce quantization noise by shifting a setting frequency characteristic so that the output of a digital signal processing section (DSP) reaches full scale of a D/A converter, and increasing the output of the D/A converter in the opposite direction by the value of the shift. CONSTITUTION:The quantity of the shift is decided so that a DSP output reaches the full scale of a D/A converter 14 based on a maximum level of the frequency characteristic set by a control section 12, and coefficient of digital signal processing is decided so as to obtain a frequency characteristic obtained by shifting the setting frequency characteristic by the quantity of shift. Then the digital signal processing (DSP) is implemented based on the coefficient in a DSP section 13, the processing output is inputted to the D/A converter 14, and an electronic volume section 15 adjusts the sound volume by amplifying the output of the D/A converter by the same quantity in the opposite direction to the shift direction based on the quantity of shift to adjust the sound volume. Thus, the accuracy of the D/A converter is effectively used for the setting of various frequency characteristics and quantizing noise is minimized.

Title: Controller for road construction traffic signal
Inventor: SERIZAWA KAZUHIKO
IPC: G08G1/07
Filed: 1998-12-02
Abstract: PROBLEM TO BE SOLVED: To make relievable traffic jam when the traffic volume is one-sided by detecting via a vehicle sensor and a vehicle stoppage time counter contained in a traffic signal controller that no entering vehicle is confirmed in the opposite lane and also a stopped vehicle kept for a fixed time in a signal waiting state is confirmed respectively. SOLUTION: When a stopped vehicle that is kept for a fixed time in a signal waiting state is confirmed even if no entering vehicle is confirmed in the opposite lane, a vehicle sensor 1a or 1b detects a vehicle 11 and a vehicle stoppage time counter 7a or 7b starts to count the time. When the count value of the counter exceeds a prescribed threshold, a switch control circuit 10 receives the output of the count value and actuates a switch 8 to switch a blue signal to a red one of a traffic signal 5b. Then a vehicle 12 which traveled ahead while watching the blue signal of the signal 5 actuates the switch 8 to switch the red signal to the blue one after a time when the vehicle 12 passed through a construction section 3 has passed. As a result, a traffic jam can be relieved even if the traffic volume is one-sided.

Abstract: PURPOSE:To lengthen an inlet pipe and lower the total height of an engine by forming an air-intaking device with a collector and right and left inlet manifolds, which are formed as an integrated body together with both right and left air chambers and air-intake passages for a low engine speed. CONSTITUTION:An air-intakeing device is formed with a collector 28 and right and left inlet manifolds 35a and 35b, which are formed as an integrated body together with right and left air chambers 29 and 30 and air-intake passages 371 to 374 for a low engine speed. At the time of a low or medium engine speed, by fully closing closing-control-valves 461 to 464, which are arranged at right and left run-off ports 281 to 284 of the collector 28, the intake air, which flowed into the collector 28, is sucked into a combustion chamber from air-intake passages 31 to 34, which are situated under the collector 28, via air-intake passages 371 to 374 for the low engine speed. In this case, since the distance between the right bank and the left bank is large enough, the air-intake passages 31 to 34 can sufficiently be lengthened. In addition, since the air-intaking device is formed with three compact divisions and is of a flat shape, the total height of the engine can be lowered.

IPC: G03G15/02
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To prevent the end leak in a conductive roller used as a charging roller in an electrophotographic device. SOLUTION: A conductive roller 2a is formed of a multilayer structure in which a core metal 10 is covered with a low resistance conductive elastic layer 11 and a high resistance layer 12. In the end part of the conductive roller 2a, the cross angle of the end surface of the low resistance conductive elastic layer 11 with the cylindrical surface of the high resistance layer 12 is set to an acute angle θ. In actual use, the conductive roller 2a is laid in the state where the circumferential roller surface makes contact with a photoreceptor. The distance of the end surface of the low resistance conductive elastic layer 11 with the photoreceptor is extended for the portion that it is set to an angle as crosses the high resistance layer 12 at an acute angle. Thus, the leak is difficult to occur by this portion.  The end surface form of the low resistance conductive elastic layer 11 is formed by cutting. The burr or liquid basin formed when a high resistance material is formed by application can be removed by the cutting.

Title: High efficiency lighting fixture for vehicle
Inventor: TERAYAMA TAKASHI
IPC: F21V7/08
Filed: 1991-12-03
Abstract: PURPOSE:To provide a bright lighting fixture by making almost the whole amount of light from a light source a light beam directed to a second focal point by providing a third reflection surface for diffusing light corresponding to the shape of a fourth reflection surface in the light beam, and by carrying out radiation by the fourth reflection surface. CONSTITUTION:The abutted light from a light source 2 is projected forward as a light beam focused to a second focal point F2, by a first reflection surface 31. Since the opening part 31a of the surface 31 is covered with a second reflection surface 32 of concaved spherical surface with the light source 2, or a first focal point F1 serving as a center, the light abutted on the surface 32 is also fed back to the focal point F1, and almost the whole amount of the light beam emitted from the light source 2 is made as a light beam directed to the focal point F2. The light beam focused at high efficiency is diffused by a third reflection surface 33, and is converted into a parallel light beam by a fourth reflection surface 34. As a result, the light from the light source 2 is not lost in the middle but is incident as a parallel light in a lens 4. All of the light can be utilized as effective radiation light, and a bright light fixture can thus be provided without reducing luminous flux utilization factor.

Title: Driving circuit for movable figurative subject
Inventor: SATO YASUTA
IPC: A63H13/02
Filed: 1989-12-28
Abstract: PURPOSE:To apply a brake to a motor and to always maintain it at the normal attitude angle of a movable figurative subject main body by turning off the power source of the motor and reducing the driving coil of the motor when detecting the prescribed angle of the movable figurative subject main body with an attitude angle detecting switch. CONSTITUTION:When sound with level exceeding a prescribed level is caught with a microphone 5, a NAND 1 drives an FF, and operates a motor driving switching element Q2, and drives the motor 7 rotatably. The outside shape of the movable figurative subject main body is bent by the rotation of the motor 7. When the attitude angle detecting switch 28 is turned on, a NAND 2 inverts output only for a time constant T. Thereby, the FF stops the driving of the motor driving switching element Q2, and turns on a switching element for short-circuiting Q3. The electric charge of the driving coil of the driving motor 7 is discharged by turning on the element, and the motor 7 receives the brake, then, stops suddenly, which always makes the motor stop in a prescribed normal state even when different loads are applied to the motor.
