Title: Television picture projector
Inventor: TEJIMA AKIHIKO
IPC: H01J31/10
Filed: 1987-08-28
Abstract: PURPOSE:To improve the heat dissipation effect of a radiator by constituting the radiator and a shield metallic fixture independently and separately with respect to the axial direction of a cathode ray tube in a device using a projecting lens so as to project a picture onto a screen with magnification. CONSTITUTION:The radiator 4 is fixed to a radiator fixing metallic fixture 12, and in using a heavy metal (such as zinc) for the type of material of the radiator 4, the shield effect against X-ray is improved and it is possible to mount the radiator 4 at the outside of the X-ray shield metallic fixtures 9, 10. Thus, the heat dissipation from the radiator 4 is made sufficient and the entire temperature is decreased, then the loss of the cooling liquid 5 through adhesives 13, 14, a shell lens 3 and a packing 7 is reduced. Furthermore, the packing 7 and its protection cover 8 are provided to a part where the temperature hardly rises in the structure as above so as to prevent the fatigue of the adhesives 13, 14 due to repetition of expansion/contraction of a large degree.

Title: Semiconductor laser element
Inventor: KUNII TATSUO
IPC: H01S5/042
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To perform continuous tuning over a wide wavelength range. SOLUTION: This element 100 is provided with a first passive waveguide 110a where a first Bragg diffraction grating 150a with a uniform grating cycle is formed, a second passive waveguide 110c where a second Bragg diffraction grating 150c with a non-uniform grating cycle is formed, and an active waveguide 110b for connecting the first passive waveguide 110a and the second passive waveguide 110c. In this case, the grating cycle of the second Bragg diffraction grating 150c is made longer as separating from the active waveguide 110b. Thus, the reflection position of light P1 in the second passive waveguide 110c indicates wavelength dependency, and wavelength tuning is made possible without causing mode skipping. As a result, the wavelength range capable of continuous tuning is enlarged.

Abstract: PURPOSE:To eliminate the variance of the magnetic gap length by forming an abutting part abutting along the edge line of the magnetic gap face of a thin film layer, and a non-abutting face, which faces the face facing a ferrite cover of the thin film layer with an abrasive layer between them, on the face facing the thin film layer of the ferrite cover. CONSTITUTION:A thin film layer 11 where a magnetic transducer is formed is provided on a ferrite substrate 12, and a ferrite cover 13 is provided on the substrate 12 of the face facing the thin film layer 11.

Since the adhesive layer which is a large cause of the variance of the magnetic gap length is eliminated in this manner, the magnetic gap length is determined by only the thickness of the thin film layer 11, and consequently, the variance of the magnetic gap length is eliminated.

Abstract: PURPOSE:To provide a method for production in which needlelike magnetic iron oxide grain powder, having a uniform grain size and a high axial ratio (diameter of the major axis/diameter of the minor axis) and better in coercive force distribution without any dendritic grains mixed therein is industrially obtained. CONSTITUTION:An oxygen-containing gas is passed through a reaction solution between an aqueous solution of a ferrous salt and an alkaline aqueous solution in an amount less than equiv. to produce needlelike goethite nuclear grains and a reaction solution of the ferrous salt containing the aforementioned needlelike goethite nuclear grains is kept at <=60 deg.C in a nonoxidizing atmosphere. An alkaline carbonate in Si an equiv. amount based on Fe<2+> in the above-mentioned reaction solution of the ferrous salt is subsequently added.

Abstract: PURPOSE:To detect a line fault in real time by discriminating it as a line fault when any of a call tone of an exchange station is not detected during talking and calling by an automatic notice device and raising an alarm. CONSTITUTION:When a telephone set is in use, a photocoupler 24 provided to a telephone line 12 is always lighted to detect it that a busy/call signal detection circuit 30 is in operation.

Title: Fixing roller and fixing device
Inventor: KISHINO KAZUO
IPC: G03G15/20
Filed: 1995-08-25
Abstract: PROBLEM TO BE SOLVED: To provide a fixing roller excellent in durability of toner releasing property and small in reduction of the outer diameter and to provide a thermal fixing device having stable carrying property and durability by controlling the JIS-A hardness of a rubber layer to a specified range. SOLUTION: This fixing roller 1 is produced by forming a rubber layer 3 comprising an addition-type liquid silicone rubber material compounded with dimethylsilicone oil having >=100000cs viscosity around a metal core 2. The JIS-A hardness of the silicone rubber compounded with an oil of >=100000cs viscosity is controlled to 5 to 30 deg.. If the JIS-A hardness of the silicone rubber exceeds 30 deg., the material has a high viscosity and problems about processing sometimes occur. The precipitation speed of the compounded oil to the silicone rubber roller surface after hardening is too slow so that enough toner release property can not be obtd. If the JIS-A hardness of the silicone rubber is <=5 deg., the material has a low strength and is not suitable as the fixing roller of the thermal fixing device of an image forming device.

The main section 1 first detects whether the pan 31 is moved leftward as shown by an arrow 41. When not the leftward but the rightward movement is detected, the main section displays that the scroll operation is requested. The images area eventually scrolled in the screen in correspondence to the movement that follows the movement of the pen 31.

Title: Viterbi decoding circuit
Inventor: FUJIWARA TSUNEO
IPC: G11B20/18
Filed: 1995-08-25
Abstract: PROBLEM TO BE SOLVED: To reduce the capacity of a decoding memory by optimizing how to select a survival path. SOLUTION: A branch metric arithmetic section 1 calculates a branch metric of each branch. An adder section 2 uses a branch metric to be calculated to obtain a path metric of each survival path. When competitive inputs A, B are equal to each other, a path metric value of a path transiting to a state S00 via a state S00 and a path metric value of a path transiting to a state S11 via the state S11 are given to a comparator section 3 and a selection section 4 selecting the input A. When the path metric values of competitive paths are identical to each other, a path transiting to a state S00 via the state S00 or a path transiting to a state S11 via the state S11 is used for a survival path. As a result, a converging time of a transition pattern taking much time for convergence of the path is minimized to reduce the capacity of the decoding memory.
