Title: Two-dimensional position detector
Inventor: TACHIBANA YUKIMASA
IPC: G01B11/00
Filed: 1986-12-08
Abstract: PURPOSE:To detect the two-dimensional position of an object by using one photodetector by adhering a target where four element surfaces are arranged to the object and forming an image of the target on a photodetection surface where four photoelectric converting elements are arranged. CONSTITUTION:The embodiment of the combination signal consisting of one group of respective signals 16a1-16d3 outputted at the same time by four photoelectric converting elements of a photodetection part 13 has a prescribed embodiment when an image of a cross line formed of respective edge of the four element surfaces of the target 10 fixed to the object 11 of position detection on the photodetection surface 14 of an optical mechanism 17 meets a virtual cross line partitioning the four photoelectric converting elements on the photodetection surface 14. A relative moving mechanism is driven through an arithmetic part 32 and a control part 37 so that the embodiment of the combination signal has the prescribed embodiment. Consequently, the position of the target 10, i.e. the position of the object 11 is determined by using the determined position of a detection part 18, i.e. the photodetection surface 14. Therefore, only one photodetection part 18 is required for photodetection and there is no influence of variation in light source intensity, disturbing light, etc.

Title: Stator of electric motor and method for manufacturing it
Inventor: SAWANISHI HIROHISA
IPC: H02K15/02
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To reduce the capacitance between the winding and a stator core and thereby to restrain a leakage current by alternately stacking one or several stator laminations and one or several stator laminations of different slots. SOLUTION: A stator core 1a is structured by alternately stacking a stator lamination 2a provided with a large slot 3a and a stator lamination 2b with a small slot 3b. Because a slot insulation 4 is inserted and mounted in contact with the inside wall of the small slot 3b in the lamination direction of the stator core 1a, there is a gap 7 having the length of the small slot 3b protruding from the large slot 3a between the slot insulation 4 and the inside wall of the large slot 3a. Therefore, this structure makes wider the distance between the conductors of the winding 6 and the inside wall of the slot and thereby makes it possible to reduce the capacitance between the winding and the stator core.

Title: Device for recording/reproducing optical information
Inventor: SHIKICHI SATOSHI
IPC: G11B7/09
Filed: 1988-11-21
Abstract: PURPOSE:To surely detect abnormality even if the speed of an objective lens is extremely low when AT control is failed by previously storing the position of an objective lens corresponding to one track piror to recording or reproducing and detecting tracking abnormality at the time of recording/reproducing based upon the stored contents. CONSTITUTION:The title device is provided with a means for comparing a recorded relative position with a detected relative position to detect tracking or focusing abnormality based upon the compared result. Since the position of the objective lens 110 against an optical head 121 correspondingly to one track is stored, abnormality can be more surely detected by comparing the position of the objective lens 110 in a scanning process even if the speed of the objective lens 110 at the time of releasing AT control is extremely low. Even when noise appears on a tracking error signal, it is unnecessary to average plural scans, so that the rapid operation of the device can be attained.

When the clock signals (3) are inputted, the output of the FF 20(1) is inverted under a condition where a two-input/one-output NOR circuit 50a is 'H' and the output of a NOR circuit 40a becomes 'H'. The FF 20(1) maintains the same state until it is reset. When such operations are repeated at every third period of the clocks CLK (1), the clocks CLK (1) are frequency- divided by three by the positive output Q of the FF 20(1) and, at the same time, output pulses (2) having a duty factor of about 50% are obtained.

IPC: H04N1/405
Filed: 1993-10-29
Abstract: PURPOSE:To suppress the influence of dispersion in the characteristics of a reading system by applying the same threshold value to two picture elements continued in a main scanning direction. CONSTITUTION:Signal level difference between the image signal of an odd- number picture element and the image signal of an even-number picture element inside a CCD line image sensor 15 is examined. When the difference is large, multi-level dither processing is performed by using a threshold value matrix XMb where the same value are arranged twice in the main scanning direction. In this case, the signal level difference between the image signal of the odd- number picture element and the image signal of the even-number picture element inside the CCD line image sensor 15 is examined. When the difference is large, the mean value of the image signals of two picture elements adjacent in the main scanning direction is used as the picture element value of an attentioned picture element defined as a processing object at that time so as to realize the similar effect by using one threshold value matrix XMa.

Title: Material for non-contact type seal
Inventor: ISHIBASHI MASARU
IPC: F04D29/02
Filed: 1991-11-08
Abstract: PURPOSE:To obtain a non-contact type sealing material which can inhibit the adhesion of fine particles by impregnating the ceramic surface with a polytetrafluoroethylene resin followed by heat treatment. CONSTITUTION:Ceramic 2 is impregnated with a polytetrafluoroethylene resin 7 in its surface and heat-treated to give the objective non-contact type seal material. When the ceramic is coated with a polytetrafluoroethylene resin in its surface, as electrical dissociation is carried out with the ceramic surface in water, the OH groups on the ceramic surface does not contact with water directly, thus the driving force of fine particle adhesion by electric charge is removed. Additionally, the polytetrafluoroethylene resin has water-repellent effect and causes no adhesion of fine particles. The polytetrafluoroethylene resin 7 fills crevasses 6 on the surface with anchor effect to smoothen it thereby the adhesion of fine particles to the surface becomes difficult.
