Patent JP-S55417-A (JP)
Title: Frequency comparator circuit
Inventor: ASAMI FUMITAKA
IPC: H03K5/26
Filed: 1978-05-23
Abstract: PURPOSE: To accomplish the frequency comparison in high accuracy by generating signals at H or L level from a latch circuit in accordance with the duration of the period of the input signals for a reference period which is preset by a reference oscillator and an n-stage counter.  
     CONSTITUTION: In case the period of an input signal Fin is longer than a preset one t, an n-stage counter C 3  has its counted value reset in response to the signals Fin, which are inverted by an inverter I 1 , so that the clock counting operations are restarted from a zero condition. As a result, the period t becomes 2 n-1  times of the period of (n-1) step or the clock. In this case, since the period t is shorter than the period T 1  of the signals Fin, the counter C 3  finishes its counting operation before the subsequent input signals Fin arrive. As a result, an output Qn is inverted from level H to level L and reset so that it is inverted again from the L level to the H level, thus repeating these operations. In the opposite case, on the other hand, the opposite operations are accomplished. As a result, the period comparison can be performed in high accuracy even for the signals having a relatively long period.

Title: Apparatus for automatic lifting of working machine
Inventor: IEGI KUNIHIKO
IPC: A01B63/10
Filed: 1995-03-20
Abstract: PURPOSE: To automatically lift a working machine connected to the rear part of a power farm machine and keep the working machine at the lifted position when a speed change lever is shifted to a reverse position and prevent the change over of a spool of a lift cylinder even by shifting the speed change lever to the reverse position after the end of the work. CONSTITUTION: This lifting apparatus is provided with a 1st switch 25 to be closed by the shifting of a speed change lever 18 to the reverse position, a 2nd switch 28 to be closed by the shifting of a lift lever 19 to the top position and an electric motor 28. The switching shaft 29 of the spool of a lift cylinder 22 is connected to the swinging shaft of the electric motor 28 through a rod 30, a rotary arm 31, etc. The electric motor 28 is actuated to pull the rod 30 forward and lift the working machine by shifting the speed change lever 18 to the reverse position. Since the power circuit is cut off after the end of the work, the switching shaft 29 of the spool does not turn to the lifting side even by shifting the speed change lever 18 to the reverse position.

Title: Connecting and separating device for pipes
Inventor: OI YUKIO
IPC: E02D1/02
Filed: 1985-03-26
Abstract: PURPOSE:To easily and exactly perform a survey for the ground by connecting connectors with claws to be fitted into the recessed portions of a pipe through a shape keeper in a foldable manner. CONSTITUTION:When a wire 50 attached to the upper shape keeper 42 is pulled to pull up upper arms 38 and 40, the shape keeper 42 is foled, a connector 32 is pulled toward the central direction, and a claw 36 comes out of a recessed portion 34. When a wire 50 attached to the lower shape keeper 42 is pulled, the lower claw 36 also comes out of the recessed portion 34, and the connector 32 is pulled toward the central direction. Since both the connectors 36 are pulled toward the central direction, despite the existence of projections for measurement, formed on the inner surface of a measuring tube 10, the pulling-up of pipes through the center is made possible.

Title: Heat exchanger for heating refrigerant
Inventor: MATSUMOTO KIYOSHI
IPC: F24F5/00
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To provide an efficient heat exchanger for heating refrigerant in a low cost by a method wherein a pipe for flowing refrigerant is wound around a cylinder provided with fins at its inner surface. SOLUTION: A pipe 2 is wound on a circumference of an outer periphery of a cylinder 1 provided with some fins at its inner side. The cylinder 1 and the pipe 2 are used for transferring heat through metallic contact. In this case, the cylinder 1 is made such that some fins are integrally formed by metallic drawn material such as aluminum at its inner side. In addition, refrigerant inlet side of the pipe 2 is arranged at an inlet port side for combustion gas. Such a quite simple structure causes the U-bent parts of the pipe to be connected and all the cylinder and pipe to be contacted to each other, resulting in that no useless state may occur in a heat transfer.  In addition, a heat exchanger for heating refrigerant can be formed simply by using metallic drawn material such as aluminum which can be integrally formed with the inner side fins and at the same time the device is integrally formed with inner side fins to cause its heat transfer to be made well. Further, a heat transfer efficiency can be improved and at the same time it is possible to reduce an abnormal super-heating of the refrigerant at the refrigerant outlet port.

Title: Optical information reader
Inventor: MUSHIYA TOORU
IPC: G11B7/12
Filed: 1983-04-11
Abstract: PURPOSE:To prevent the effect of double refraction owing to the transparent protecting layer of a disk and furthermore to prevent a back-talk phenomenon to be extend on the luminous flux radiated from a laser light source, by providing a half mirror into the optical path between the light source and an objective, and a 1/4 wavelength plate into the optical path between the light source and a recording medium. CONSTITUTION:A beam splitter 23 contains a half mirror having a 50% reflective transmission characteristic on the reflection surface. Thus the luminous flux incident to the splitter 23 is transmitted by 1/2 light quantity and converted into the clockwise or counterclockwise circular polarized light through a 1/4 wavelength plate 24. The light reflected by an information track 26a and transmitted through the splitter 23 to be sent back to the light source side is polarized in the direction orthogonal to the polarizing direction of the light delivered from a laser diode 21. Therefore no optical interference is caused and no back-talk noise is produced. Then each half of the normal and abnormal light beams is reflected by the splitter 23 and received by an optical detector 29 even though the reflected light has the double refraction owing to a transparent protecting layer 26B of a disk 26. Thus it is always possible to obtain the stable information signal and error signal with no variance.

Title: Light converging device
Inventor: KONDOU MITSUSHIGE
IPC: G11B7/135
Filed: 1983-04-07
Abstract: PURPOSE:To reduce the cost of a light converging device by forming a spherical reflecting mirror, beam splitter, and parallel plane glass without using any spherical lens, and reducing polished surfaces. CONSTITUTION:Projected light from a spot light source 12 placed in the center of curvature of the spherical mirror 13 is incident to a mirror 13 which crosses the contact plane of the mirror 13 at right angles, so the light returns through the original optical path accurately and reflected light is converged without any aberration, but converged light enters the original light source again. For this purpose, the beam splitter 14 with a reflecting spherical surface 15 is placed and the spot light source 12 is set in the center of curvature of the reflecting spherical surface 15, obtaining a nonaberration light spot 6 on the end surface of the beam splitter 14. When, however, the light spot is formed in the air, the converged light has aberrations because of the difference in refractive index between the beam splitter 14 and air, so a parallel plane plate 11 having a larger refractive index than the beam splitter 14 is arranged to compensate the aberrations, and then the aberrations of the convergence system are reduced by selecting the thickness of the parallel plane plate 11 properly.
