Title: Light guide method for lamp for illumination
Inventor: SAIKI ATSUSHI
IPC: G09F9/00
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To provide a light guide method for illumination by which the loss of light projected from a lamp is reduced, efficient illumination without irregularity as a whole is obtained and such simple constitution that the installing position of the lamp is not regulated is realized even when the irradiating direction of the light projected from the lamp is different from a display direction or a display position and a created matter exists at a display part in terms of design. SOLUTION: The light emitted from the lamp 12 installed on a substrate 11 is made incident on a light guide plate 13 consisting of a transparent organic material such as acrylic resin and irregularly reflected on an irregular reflection surface 14 obtained by arranging a triangular knurling tool formed at the refraction part of the light guide plate in parallel with a light guide path. Thereafter, it arrives at a display part 15 while it is repeatedly reflected in a plate body 16 so as to almost uniformly illuminate the display part 15 as a whole. Besides, the lamp 12 is easily installed on the identical substrate to the substrate 11 having a main function from the set of a refracting position.

Abstract: PURPOSE:To obtain a multi-point photometer effective for cameras, by arranging a multi-split photometry circuit, an automatic focus adjusting means, a means for determining a brightness distribution end value, a means for outputting latitude information of a film and a means for judging on whether the brightness distribution irrelevant to the decision on exposure level is increased depending thereon. CONSTITUTION:An So is turned on by the operation of a switch and a photometry circuit 13 starts to send brightness signal in areas of an object field to a CPU. With the closing of a switch S1, an automatic focus detecting circuit 14 operates by a signal of the CPU to perform a focusing on an object ad when the object gets, in focus, it sends an adjustment ending signal to a processor interrupt mechanism via a gate 23 to disable a focus adjustment. Then, the CPU processes the brightness signal to judge on whether the deviation of the maximum and minimum brightness of the object field from a reference value is within a specified value determined by latitude of a film used on the brightness of the object field portion containing an area used by the automatic focus detection mechanism for measuring distance as reference to determine the exposure level to ensure that the brightness range of the object field portion will meet the latitude of the film used.

Title: Joint ferrite magnetic head
Inventor: AKIYASU HIROSHI
IPC: H01F1/34
Filed: 1988-08-15
Abstract: PURPOSE:To suppress the magnetization of a magnetic head, to minimize a sliding noise, and to obtain a high C/N by making the crystal orientation of a front core part, which is composed of monocrystal ferrite, and that of a back core part, which is also composed of monocrystal ferrite, mutually different. CONSTITUTION:Front core parts 1 and 3 to slide-contact on a magnetic recording medium and back core parts 2 and 4 to occupy most of the remaining volume of the title head and compose a magnetic circuit are respectively composed of respective pieces of monocrystal ferrite mutually having different types of crystal orientation. Therefore, even when polycrystal ferrite is not used, sufficient permeability can be secured throughout the magnetic head. Consequently, the possibility of the occurrence of the magnetization of the magnetic head can be minimized, and a satisfactory recording and reproducing characteristic can be realized. Thus, the C/N of a reproduced output signal can be improved, and the sliding noise can be reduced.
