Title: Focusing device
Inventor: KONDOU TOSHIHIRO
IPC: G03B13/24
Filed: 1978-04-10
Abstract: PURPOSE: To effect the focusing operation of high accuracy by using a pyramid prism, a reflector and a half mirror.  
     CONSTITUTION: On the optical axes 3 and 4 of an objective lens 1 and a focusing lens 2 in parallel with the former, there are arranged a pyramid prism 5 having such an apex angle as is free from total reflection, and reflectors 6 to 8. A half mirror 9 is arranged at the back of the reflector 8 at such a position as has the reflecting optical axes of the reflectors 6 and 8 coincide. As a result, the image formed by the light from the lens 1 and the image formed by the light from the lens 2 are overlapped on the mirror 9, and the overlapped image is observed from the back of the mirror 9 to detect the degree of coincidence thereby to detect the focal point. Thus, a remarkably bright image is used so that the accurate focusing operation can be performed.

Title: Frame synchronous type data transfer system
Inventor: OGAMI CHOJI
IPC: G06F11/10
Filed: 1992-01-31
Abstract: PURPOSE:To easily structure and expand the system by adding individual number information on an opposite party at the head of a frame and a check sum word at the tail. CONSTITUTION:A transmission frame generating means adds the ID word 10 indicating the individual number of the transfer destination at the head of an information word 30, performs binary addition in word units from the ID word 10 to the tail information, and adds the low-order 8 bits of the addition result as the check sum word 20 behind the tail information word to constitute one frame. A reception frame synchronizing means performs sequential binary addition in word units from the 1st received word and judges that a received word which arrives next is the head of the frame when the value of the low-order 8 bits of the addition result at the point of time of the addition matches the word which is received next. When not, on the other hand, it is judged that the frame synchronism steps out, the 1st word of a reception frame which is expected next is shifted forward or backward, and this operation is repeated until they match each other.

Title: Rear wheel steering device for vehicle
Inventor: KAMIMURA HIROKI
IPC: B62D7/14
Filed: 1989-02-20
Abstract: PURPOSE:To make equal the feeling in turning right and left by setting a rear wheel steering angle in the opposite phase area against the same handle rotating angle so as to be different at right turning and left turning. CONSTITUTION:The turning of an input shaft 25 of a rear wheel steering device is transmitted to a driven shaft 33 by gears 32, 34. A plate-shape cam member 30 is fixed in the driven shaft 33, and a steering rod 36 of right and left wheels are moved along the surface of a cam 35 by rotary contact rollers 37l, 37r. The right and left surfaces of the cam 35 are formed in asymmerty. The right cam surface 42r is reduced than the left cam surface 42l, and the lower surface 43r is oppositely enlarged to make a cam surface diameter 2R equal. Consequently, when the turning of the input shaft 25 is within the predetermined, the rollers 37l, 37r are contacted to the equal cam surfaces 41l, 41r, and a steering rod 36 is in neutral. When the turning is more than the predetermined, the rollers 37l, 37r are contacted to the cam surfaces 43l, 43r, and the rod 36 is moved. Consequently, the feeling in turning can be softened.

Abstract: PURPOSE:To simplify the structure of a burner and enhance combustion efficiency by afterburning and circulating repeatedly an imperfect combustion gas which is ejected from a gas ejection hole of an inner combustion cylinder into an outer combustion cylinder with back fire of a heating gas and heating the inner combustion cylinder. CONSTITUTION:The rear side in a combustion cylinder 1 is turned into a decompression section by a compressed air (a) which is supplied from an air supply duct to the an outer cylinder 1, which forces the compressed air (a) to flow back along the outer periphery of an inner combustion cylinder 15 so that the compressed air is mixed with an imperfect combustion gas (g) which is injected from the inner combustion cylinder 15 in the outer combustion cylinder 1. The mixed gas is repeatedly circulated through the outer combustion cylinder 1 and turned into a high temperature gas, thereby promoting thermal vaporization. The imperfect combustion gas (g) which is ejected from the inner combustion cylinder 15 is heated with the back fire of the high temperature gas circulating around and ejected outside from a gas discharge cylinder 7 as a high temperature perfect gas. This construction makes it possible to enhance the combustion efficiency in small size and low weight structure.

IPC: H04N9/07
Filed: 1983-03-15
Abstract: PURPOSE:To obtain a solid-state image pickup device having excellent picture quality and less generation of a chrominance signal because of the error of vertical correlation by using a video signal comprising three scanning lines so as to obtain a red signal, a blue signal and a luminance signal. CONSTITUTION:A transparent signal W and a green signal G are obtained from the n-th scanning line of a solid-state image pickup element and a cyan CY and a yellow signal Ye are obtained alternately from the (n+1)-th scanning line at each other picture element. In applying 1H delay and 2H delay to the output signal of the solid-state image pickup element by using two 1H delay lines, when the [n+1(H)]th output signal is obtained, the signal of the n(H)- the [n-(H)] is obtained. In forming an average value by adding respectively the [n-1(H)] and the [n+1(H)] CY signals by 1/2 each, the signal is formed by interpolating the CY signal of the W signal at the n(H) being a reference. Further, the red R signal is obtained by operating the CY signal and the W signal thus obtained.

Title: Spherically pointed optical fiber and its production
Inventor: IMOTO KATSUYUKI
IPC: C03C13/04
Filed: 1985-03-06
Abstract: PURPOSE:To manufacture a spherically pointed optical fiber having high coupling efficiency with good reproducibility and controllability by sticking a high- refractive index liquid having a dopant of a high diffusion rate to the top end of an optical fiber, heating indirectly said part to a spherically pointed shape and changing continuously the refractive index distribution in the spherically pointed part. CONSTITUTION:The optical fiber 1 is inserted into the high fractive index liquid 11 filled into a vessel 10 so that the liquid 11 sticks near to the top end thereof. The optical fiber 1 stuck with the liquid 11 is then inserted into a vessel 8 and the vessel 8 is heated by the flame of a burner 4 while the fiber is held fixed in the space to heat indirectly the top end and to work the top end to a spherical or tapered shape. Alkaline metallic ions diffuse and penetrate quickly into the fiber 1 when an aq. soln. of alkaline metallic silicate is used for the liquid 11. The refractive index is then distributed so as to decrease continuously from the outside surface toward the inside, by which the coupling efficiency to the optical fiber of a semiconductor light emitting element is improved and Fresnel reflection is prevented.

A comparator 58 compares the phase error voltage with the standard voltage 59 to output a positive or negative control signal. The positive or negative control signal makes an up/down counter 54 count up or down. Then the lower bit of the counter controls the data selection of a data selector 68 and the upper bit controls the divider.
