Title: Data detector
Inventor: HAYAMIZU ATSUSHI
IPC: H04L25/08
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To provide a data detector capable of detecting and outputting a bit clock extracted from a waveform equalization signal with a comparative simple configuration and a small circuit scale. SOLUTION: This detector is used for a data transmitter that recovers a data signal by using a Viterbi decoder 7 to decode a waveform equalization signal resulting from applying waveform equalization to an output of recorded data (a) through a transmission line via an A/D converter 6 and detects and outputs a clock signal required for A/D conversion and decoding from a waveform equalization signal b'. In this case, when an output (b) exceeds a reference signal level ref, it is recognized that sign inversion of a bit synchronization clock takes place with respect to the waveform equalization signal b' and a shift circuit 10 provides a clock signal based thereon to an A/D converter 6 and a decoder 7 via a comparator 8 and a phase synchronization circuit 9.

Title: Optical waveguide device with achromatic mode index type lens
Inventor: NAKAYAMA YOSHINOBU
IPC: G02B6/122
Filed: 1989-10-23
Abstract: PURPOSE:To eliminate the chromatic aberrations of the lens by determining the equiv. refractive indices of an optical waveguide and a mode index type lens to satisfy prescribed relations. CONSTITUTION:Light of a wavelength lambda propagates at an equiv. refractive index N1 in the 3-layered slab type optical waveguide consisting of a substrate 4 having a refractive index ns, the optical waveguide 5 which is formed on the substrate 4 and has a refractive index nf1 and film thickness tf1, and a clad layer having a refractive index nc1. The achromatic mode index type lens 6 is provided in the optical waveguide 5 so that this device is given as the 3-layered optical waveguide consisting of the refractive index nf2 and film thickness tf2. The eqiv. refractive index of this part is designated as N2. The chromatic aberration of the achromatic mode index type lens 6 is expressed by equation II according to paraxial theory. If there are change rates DELTAn1, DELTAn2 of n1, n2, DELTAf is zero when the difference of the right side is zero. The chromatic aberration is thus eliminated even with one piece of the lens. Namely, the refraction in the optical waveguide 5 is governed by the equiv. refractive index and, therefore, equation III and equation IV are obtd. when the refractive indices are substd. with the equiv. refractive indices N1, N2. In other words, the chromatic aberration is eliminated when equation I is attained.

Title: Cryogenic vessel for superconducting magnetic coil
Inventor: NAKAO HIROYUKI
IPC: F17C3/08
Filed: 1988-10-31
Abstract: PURPOSE:To make a closing valve operate very properly by making up the mainframe of a nonreturn valve with a material which is not magnetized even though its material is treated with heat. CONSTITUTION:When a nonreturn valve is used in an intensive magnetic field because a cryogenic vessel for superconducting magnetic coil comes close to its magnetic field, the mainframe of the nonreturn valve is magnetized and is liable to perform abnormal motions. Then an austenitic stainless steel material is replaced with other materials in order to prevent the mainframe of this valve from being magnetized. However, when these materials are incorporated into this vessel, it is necessary for them to be welded and to be treated with heat so that component members of this valve are unified. Consequently, the mainframe of the valve is made up by metallic materials such as aluminum, copper, and the like or ceramic materials because they are not magnetized when welded or treated with heat.

Title: Controller for electrostatic printing device
Inventor: FUJITSUKA KAORU
IPC: G03G21/00
Filed: 1985-12-09
Abstract: PURPOSE:To execute in a short period the work from a preparation of a printing master to printing, by controlling a scroll drum at each different rotating speed at the time of a copying mode and at the time of a printing mode, and controlling paper feed timing and a feeding speed of a form, etc., in accordance with the rotating speed. CONSTITUTION:A copying operation is repeated by the number of sheets to be copied which has been set in advance, and also, the speed in the copying operation is PV1, and when a printing mode is selected by a button on an operating panel 180, the printing mode consists of an engraving process (speed PV2) for preparing a printing master and a printing process (speed PV3) for executing the printing by the printing master. In the printing process, electrostatic printing is executed by using the printing master which has been prepared by the engraving process, but since there is no exposure process of an original 2, a rotating speed of a photosensitive body 37 and paper feeding and carrying speed become the highest speed PV4. That is to say, the printing process in which a toner image which has been formed on the master by a high speed rotation is transferred on a form 85 and fixed is repeated by the number of sheets to be copied which has been set in advance. In this way, the work extending from a preparation of the printing master to printing can be executed in a short period.
