Title: Zoom lens
Inventor: SHIBAYAMA ATSUSHI
IPC: G02B15/20
Filed: 1989-08-18
Abstract: PURPOSE:To provide the zoom lens which exhibits an excellent image-forming property with a smaller number of lens elements by expanding an air spacing between a 1st lens group G1 and a 2nd lens group G2, reducing the same between the lens groups G2 and a 3rd lens groups G3 and changing the same between the lens groups G3 and a 4th lens groups G4 at the time of variable power from a wide angle end to a telephoto end and providing specified conditions. CONSTITUTION:While the air spacing between the 1st lens group G1 and the 2nd lens group G2 is expanded, the air spacing between the lens group G2 and the 3rd lens group G3 is reduced and the air spacing between the lens group G3 and the 4th lens group G4 is changed to satisfy the conditions expressed by inequalities at the time of the variable power from the wide angle end to the telephoto end. In the inequalities, the focal length at the wide angle end of the zoom lens is designated as fw, the focal length of the lens group G2 as f2, the focal length of the combined negative lens L22 in the lens group G2 as f22, the Abbe number of the positive lens L22p in the combined negative lens L22 in the lens group L22p in the combined negative lens L22 in the lens group G2 as nu22p, and the Abbe number of the negative lens L22n in the combined negative lens L22 in the lens group G2 as nu22n. The excellent image-forming property is exhibited by the small number of the lens elements in this way and the weight of the lens is reduced; in addition, the portability and operability are improved.

Title: Detecting apparatus of extraneous substance
Inventor: HAGIWARA TAKASHI
IPC: G03F1/84
Filed: 1991-07-30
Abstract: PURPOSE:To improve precision and reproducibility by disposing two photodetectors between a light-scanning mirror and a light-sensing lens and by correcting a position automatically by a difference between a signal of a swing angle of the light-scanning mirror and a signal of the photodetector for monitoring. CONSTITUTION:Pin photodiodes 13 and 14 for scan monitoring are disposed in an optical path of an incident optical system 3 between a condenser lens 7 and a board 1 being an object of inspection, with appropriate spacing in the direction of scanning of a laser light L. In the case when a swing angle of a scanning mirror 6 does not change with time, a scanning position signal S13 is detected by the diode 13, while a signal S14 is detected by the diode 14 with rotation of the mirror 6. When the change with time of the swing angle of the mirror 6 occurs, a straight line II connecting a point P of intersection of an extension from the position of the diode 13 being parallel to the axis of abscissas and of an extension from the position of a scanning position signal S'13 being parallel to the axis of ordinates and a point Q of intersection of an extension from the position of the diode 14 being parallel to the axis of abscissas and of an extension from the position of a signal S'14 being parallel to the axis of ordinates, is obtained. A difference D between straight lines I and II represents a shift of the scanning mirror on the basis of the change with time, and only the shift is subjected to a program processing, whereby a position of detection of an extraneous substance is corrected automatically.

A confirmation data is reproduced based on this reverse modulation output at the time of recording mode.  Consequently, simultaneously with recording, the data recording state can be confirmed without necessities of increasing the laser diode LD in number and gaining the revolving speed.

Filed: 1981-12-28
Abstract: PURPOSE:To eliminate the need for stopping a machine by a method wherein a tool, which generated an abnormal dimensional accuracy is specified and changed with a stand-by tool when dimensional accuracy abnormality is detected by the dimensional accuracy monitoring device. CONSTITUTION:A work 11 is machined by a tool mounted to a main spindle 16. In this case, a memory 27 memorizes which tool has machined which location of the work.

Abstract: PURPOSE:To equivalently form the neutral net of hierarchy structure by setting the plural units of neuron models, forming the unit set of a single layer and using the unit set of single layer structure with time-sharing and multiplexing. CONSTITUTION:A unit 5 of the neuron model generates a product with digital weighting data 4 from an external part for a time-sharing and multiplexing analog signal 3.

A feedback means 7 feeds back the output of the single layer unit set means 6 to the input part of the same single layer unit set. A control means 8 multiplexes the analog signal, which is outputted from the single layer unit set means 6, from each unit 5 with the time-sharing and further executes control to use the single layer unit set means 6 through the feedback means 7 with the time-sharing and multiplexing. Thus, the neutral net can be constituted.

Abstract: PURPOSE:To obtain a magnetic high-density recording head device which realizes a narrow track easily by using a core which has cut parts for specifying track width only near a magnetic recording gap part on a surface opposed to a recording medium and has width much larger than the track width at other parts. CONSTITUTION:The cut parts 7 for specifying the track width TW are formed in a nearly I-shaped core 5 and a nearly C-shaped core 6 is welded by glass, etc., with a magnetic recording and reproducing gap 8 between.

The cores should be manufactured with extremely precise gap depth Gd or Gd' to reduce errors and work heads in quantities at a time. For example, TW is determined not by the size specified by the cut parts, but abutting precision when the nearly I-shaped core and nearly C-shaped core are both provided with cut parts and made to abut on each other like the picture head of a video tape recorder.
