Title: Production of hologram element
Inventor: SUZUKI HIROMI
IPC: G03H1/04
Filed: 1988-10-03
Abstract: PURPOSE:To eliminate the need for a sensitization processing, optical system for correcting aberrations and swelling treatment by using an alexandrite laser oscillator as a light source for recording to produce the hologram element. CONSTITUTION:The alexandrite laser oscillator 1 is provided as the light source for recording and light is released as normal pulses from this laser oscillator 1. The radiated laser light is separated to transmitted light and reflected light by a half mirror 2. The transmitted light is diffused by a lens 3 and is mode incident as reference light to a hologram recording material (a). On the other hand, the light reflected from the half mirror 2 is reflected to a mirror 4 and transmits lenses 5a to 5c from which the light is made incident as the object light condensing to a focus (c) to the recording material (a). The hologram is thus recorded on the hologram recording material in such a manner. The hologram element which does not require the optical system for correction is easily produced in this way.

Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of missing image and divided pages in the case of printing at a transmission destination because of difference between an original size at the transmitter side and print paper size at the transmission destination by reducing an image size at a transmitter side and then sending the image. SOLUTION: An exposure lamp 25 in a scanner section of a copying machine scans an original D placed on an original plate 12. A reflected light from the original D forms its image on a CCD sensor 34 via an image forming lens 32. The CCD sensor 34 converts an image of the original into an electric signal and gives the signal to a memory of an image processing section. A touch panel for operation instruction entry provided in a main body 10 is used to select a facsimile function and to enter a telephone number of the transmission destination, then a facsimile interface sends image information in the memory via a modem and a public line.  In the case that the transmission destination is a party in the North America, the transmission in matching with the paper specification in the North America is designated, then the image processing section reduces the original so as to contain the image within a corresponding size of the paper standards in the North America.

Title: Stroke detecting device for shock absorber
Inventor: AKAGI HITOSHI
IPC: F16F9/32
Filed: 1993-10-04
Abstract: PURPOSE:To accurately detect a stroke and dispense with the seal of a sensor by forming a piston rod out of magnetic material, providing a magnet to pass the magnetic flux in the axial direction of the rod, and detecting the emitted magnetic flux. CONSTITUTION:The magnetic flux emitted from the N pole of a magnet 25 passes a piston rod 6 in the axial direction and returns to the S pole on the loci shown by broken lines, and the nearer the magnet 25 is, the larger the magnetic flux density is. The Hall element of a Hall sensor 28 outputs voltage in proportion with the magnetic flux density. Consequently the piston rod 6 is moved up and down by expansion/contraction of a shock absorber, the magnet 25 fixed to it is also moved up and down so as to change the distance relative to the Hall sensor 28, hence the Hall sensor 28 outputs voltage corresponding to the position of a piston 8, and the stroke can be detected. Because the detecting device uses the piston rod 6 as a part of a magnetic circuit, the detecting accuracy becomes high. In addition because the Hall sensor 28 is provided outside an outer cylinder 1, the problem such as a seal for working oil is not generated.
