Title: Phase comparator
Inventor: SUZUKI JUNJI
IPC: H03L7/085
Filed: 1989-02-22
Abstract: PURPOSE:To improve the symmetry of an input/output characteristic by supplying the collector circuit of a 5th transistor(TR) from a power terminal and supplying the collector current of a 3rd TR via the load resistor of a 2nd TR. CONSTITUTION:First and 2nd TRs Q2, Q3, 3rd and 4th TRs Q4, Q5 and 5th, 6th TRs Q7, Q8 constitute respectively a differential amplifier. Then the collector of the TR Q7 is connected to a power terminal Vcc and the collector of the TR Q4 is connected to the collector of the TR Q3 and one terminal of a load resistor R2 and the base of the TR Q6 are connected in common. Thus, the collector current of the TR Q7 is supplied from the power terminal Vcc and the collector current of the TR Q4 is supplied via the load resistor R2 from the power terminal Vcc. Thus, the symmetry of the input and output characteristic of a phase comparator is improved independently of the switching TR Q6.

Title: Fiber for optical transmission
Inventor: SAIGO TOSHIAKI
IPC: C03C25/10
Filed: 1989-02-22
Abstract: PURPOSE:To eliminate the influence of a gelatinoid filler and to prevent reduction due to fine bending by specifying the product of the size reduction rate when the resin of a buffer layer is dipped in the filler and the modulus of tensile elasticity of the resin of a protection layer. CONSTITUTION:The fiber for optical transmission consists of a primary jacket layer (buffer layer) 2 and a secondary jacket layer (protection layer) 3 as the outer periphery of a glass fiber 1 and is used while dipped in the filler. The resin of this buffer layer 2 is formed into a sheet shape and dipped into the filler to extract uncured components sufficiently and then the size reduction rate is measured. The product of the reduction rate and the modulus of tensile elasticity of the resin of the protection layer 3 is specified below 1.0kg/mm<2>. Consequently, when the optical fiber is dipped in the filler, irregular stress resulting from the extraction of the uncured components in the buffer layer into the filler is eliminated to prevent the reduction due to fine bending, thereby improving the long-period reliability.

Title: Method for generating pattern for automatic tracking of video tape recorder
Inventor: SHIROSHITA KENJI
IPC: G11B5/588
Filed: 1983-03-14
Abstract: PURPOSE:To attain the generation of a head driving pattern with fidelity by preparing a tracking pattern and a transmission pattern as basic patterns in a pattern generator at the reproduction and combining an error pattern and the basic patterns so as to obtain a driving pattern. CONSTITUTION:When an output of an amplitude detector 14 is larger than an output of 14b at the 1/4 slow reproduction, it is meant that a video head 3a is biased toward a video track 2b on which a pilot signal f2 is recorded. Then, a moving head driving signal correcting the bias is generated at a pattern generating circuit 17 based on an output of a comparator 15 and a VTR operating mode signal 16 reprosenting the slow reproduction or the like. Further, the signal is smoothed by an LPF 18a smoothing it to a degree that an abnormal vibration is not produced to a piezoelectric element 4a and applied to the piezoelectric element 4a via a moving head driving amplifier 19a. As a result, the balance of the amount of crosstalk of a pilot signal from an adjacent track reproduced by the video head 3a is changed so as to form a servo loop, allowing to improve the tracking performance.

Title: Electron microscope which can observe energy loss image
Inventor: ETOU TERUKAZU
IPC: H01J37/147
Filed: 1981-03-25
Abstract: PURPOSE:To obtain an electronic microscope which can observe an energy loss scanning image without mounting an energy analyzer. CONSTITUTION:When an irradiated electron beam (EB) is deflected largely right as shown by a solid line EB1, is not deflected as shown by a dotted line EB2, and is deflected right as snown by a two-dot line EB3. The position of an electron which is incident on an intermediate lens 4 and its angle are deflected by deflection systems 6a and 6b so as to be always fixed. Thus the electron which is incident on a detector 7 is EB1 with special energy which passes through each point of a sample. Since the energy of the electron irradiated on a sample 2 is fixed, the separation of EB1, EB2, EB3..., by the intermediate lens 4 indicates a difference in the energy loss by the sample 2. Therefore, by detecting only the special electron EB1 and guiding it a cathode-ray tube, the energy loss image by the sample is displayed on the pertinent cathode-ray tube. When a different energy loss image is obtained, either separated electron beam EB2 or EB3 may be caught by the detector 7 by adjusting a deflection power supply.

Filed: 1979-04-11
Abstract: PURPOSE: To simplify the removal of flashes by making the dirt of a magnetic head core conspicuous by providing surface roughness with unidirectivity by finishing both surfaces of the core made of Fe-Al-Si-based magnetic alloy by polishing.  
     CONSTITUTION: Chips 3 made of Fe-Al-Si-based magnetic alloy and sliced in a fixed shape are mounted on surface plate 4 and then fixed by using an adhesive. Finishing thus arranged chips 3 by polishing provides the surface roughness of an obtained magnetic head core with unidirectivity. This core has the surface roughness unidirective and a metallic glaze, and consequently its dirt is conspicuous and the existence of a colored oxidation surface is easy to discriminate, so that there will not be any possibility that the magnetic head is constituted by the use of a core inferior in magnetism. In addition, since a place where flashes may be generated can be limited, disregarding an influence of flashes or removing flashes only at a specific position is only required.

Abstract: PURPOSE:To keep a temperature constant when a printer operates by filling a gap between a heat roller and a heater with a member of large specific heat. CONSTITUTION:The fixing unit is provided with the cylindrical heat roller 1 and the halogen lamp (heater) 2 which is arranged on the axial center of the heat roller 1 and heats the heat roller 1.

Abstract: PROBLEM TO BE SOLVED: To provide a sinking type pointing stick structure attached to the upper side of the keyboard of a notebook personal computer, manually turnable around a selection shaft parallel to the upper side of the keyboard so as to controllably re-position a cursor displayed at the lid part of the computer. SOLUTION: When the lid 26 of the computer 10 is opened, the uppermost end of the pointing stick structure 12 is projected upwards exceeding the upper side of the key cap member 38 of the keyboard 32 so as to facilitate the manual engagement and operation by the user of the computer 10.
