IPC: F16D3/2245
Filed: 1978-11-30
Abstract: PURPOSE:The captioned outer race which is obtained by bonding a joint member formed with ball grooves and cage contact faces and a shaft member contacting or engaging with this through pressing to a cup-form body obtained through drawing of a steel plate blank and which is simple, is produced with a minimum of steps and does not require many facilities. CONSTITUTION:In order to manufacture the captioned outer race to be interposed between the reduction gear and drive shaft or the like of a vehicle, a steel plate blank of a required thickness permitting plastic deformation is cut and is formed to cup-form blank with a press. Plural ball grooves W4 are roughly formed with a press on the circumferential wall W1 thereof and the ball cage contact faces W5... between the grooves are pressure-worked with a press, whereby a joint member W6 is obtained. On the other hand, a shaft member W7 is forged by steel material. It is formed with a flange part W9 having a recess W8 at the end and a coupling part W10 such as of screw around the shaft through machining. Next, the joint member W6 and shaft member W7 are fitted at the respective protruding part W2 and recess W9, and the assembly is subjected to brazing or the like in a furnace. At this time, heat treatment may be accomplished at the same time.

Abstract: PURPOSE: To achieve the improvement in optical performance by specifically arraying telecentric lenses.  
     CONSTITUTION: A lens-barrel 101 applied with antireflection on its inside surface is arrayed with a lens 40 of an outside diameter equal to the inside diameter thereof and being image side telecentric and an object side telecentric lens 41, mutually parallel in one or more array at an equal spacing. As a result of this, the surface on the image side of the lens 40 and the surface of the object side of the lens 41 act as if to form an air lens, causing the main beam 42 from an object 50 to emit through the mid-point of the second face exit height of the lens 40 of beams 43, 44, become parallel to the optical axis and go toward the lens 41. Also, the beam 45 lower than the beam 44 transmits through the first face of the lens 40 and arrives at the lens- barrel 101, where it is attenuated, thus the light intensity distribution on the projecting surface 55 becomes of Gaussion form and the lens-barrel 101 acts as an iris extending in the optical axis direction. At the same time, the effective object visual fields in the respective constituting lens systems overlap with each other in multiplicity owing to the configuration of one or more arrays, thus the distributions in the configuration direction with respect to the quantities of light integrated in the direction rectangular to the array direction become uniform.

IPC: H02P6/21
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To improve a starting torque of a brushless motor to prevent synchronization to enable hybrid starting. SOLUTION: Wiring voltages of the armature windings U, V, W of a brushless motor are combined in a resistance circuit 10a and a DC element of this combined winding voltage (induced voltage) is by a capacitor 10b and then level-adjusted by a resistance circuit 10c. In this case, the combined winding voltage waveform is distorted with the integration effect by the resistance circuit 10c and capacitor 10d. The distorted combined winding voltage waveform is compared with the reference voltage in a comparison circuit 10f, and a control circuit 11 detects position of the rotor with the position detection signal as the comparison result to switch the power feeding of the bruchless motor 4.  The control circuit 11 PWM controls the bruchless motor 4 and detects position of the rotor from the starting time of the bruchless motor 4 and switches the power feeding for the armature winding depending on the delayed position detection by the integration effect, when the rotor position is detected or forcibly switches the power feeding for the armature winding when position detection is not carried out.

Title: Image control method for image forming device
Inventor: IMAI TSUTOMU
IPC: G03G15/08
Filed: 1987-06-15
Abstract: PURPOSE:To stably detect a developed image density of a pattern latent image with high accuracy by adjusting a density bias electric field in a prescribed timing immediately before developing a reference pattern latent image, to the extent that a toner is set free from on a developer carrying body. CONSTITUTION:At the time of developing a reference pattern 5 latent image, a developing bias electric field is adjusted so that a toner is attracted nearer toward a developer carrying body 10b side than the case when an image latent image of a document is developer, and also, can be adjusted to the extent that the toner is set free from on the developer carrying body 10b, immediately before developing the reference pattern 5 latent image. In such a way, at the time of developing the reference pattern 5 latent image, even if the toner is attracted toward the developer carrying body 10b side by adjusting the developing bias, so that it becomes a developed image of a half tone, it is prevented that the toner adheres to the developer carrying body 10b. Also, an image density can be detected stably.

Title: Photographing device
Inventor: KURODA YASUO
IPC: G03B27/62
Filed: 1980-10-23
Abstract: PURPOSE:To prevent erroneous photographing work when an original is not correctly placed by controlling photographing operation by combining the detection signal of the time when the original is in a photographing region and the detection signal of the time when it is outside the region. CONSTITUTION:An original is placed within the indices 5 showing the photographable region of an original placing plate 1a, and is detected with the 1st detector 6 having a phototransistor 6a, but if it is outside the region, it is detected by the 2nd detectors 7-10. If with this constitution the original is within the indices 5, the 1st detector 6 is non-conducting and the 2nd detectors 7-10 are conducting. An AND gate 21 goes to the high level by the prescribed circuits and the gate 21 opens, thereby operating the shutter. When the original deviates to the position of the detector 7, the detector 7 goes to the low level to prevent the gate 21 from opening, thereby inhibiting the shutter operation. Thereby, the photographing of the time when the original is not correctly placed is prevented.

Filed: 1990-06-07
Abstract: PURPOSE:To obtain a highly reliable representative flow velocity by providing a flow velocity detector for every plane of a plurality of parallel measuring planes in the flowing direction, and repeatedly computing the arithmetic mean of the local flow velocities expressed by the detected signals at the same time. CONSTITUTION:Ultrasonic flow velocity detectors 2 wherein ultrasonic transducers 4a and 4b are arranged in the facing patterned are provided on measuring lines 61-63. Detected analog signals 7al-7a3 expressing the local flow velocities are inputted into A/D converters 16-18, and signals 16a-18a are always outputted. When a control signal 15a is inputted, the converters 16-18 update the signal patterns of the signals 16a-18a. When a control signal 15b is further inputted, an arithmetic-mean operator 19 computes the arithmetic mean by using the signals 16a-18a and outputs a measured signal 19a. The signal is repeatedly outputted at a specified period based on the control signals 15a and 15b of a control part 15. Since the measuring lines 61-63 are provided in a measuring region 13 and the arithmetic mean is obtained based on the local flow velocities obtained at the same time in this way, the representative flow velocity of liquid 11 can be measured in high reliability.
