Patent JP-H0285829-A (JP)
Title: Light guide
Inventor: NAKAMURA KAZUNORI
IPC: G02B6/12
Filed: 1988-09-22
Abstract: PURPOSE:To prevent the thickness of a waveguide from increasing even if the working length thereof is increased by forming a core layer of a material which generates optical higher harmonics by a nonlinear optical effect and providing a clad layer which is lower in refractive index stepwise or continuously toward the outer side with respect to the optical higher harmonics. CONSTITUTION:The core layer 1 of the light guide 3 constituted of the core layer 1 in the central part consisting of a material having a high refractive index and the clad part 2 of the circumference consisting of a material having a low refractive index consists of the material which generate the optical higher harmonics (SHG) by the nonlinear optical effect. The clad layer 2 is transparent to the optical higher harmonics and has the structure in which the refractive index is lower stepwise or continuously toward the outer side. The refractive index of the core layer 1, designated as n0 and the refractive index of the outermost layer, designated as nN, are so determined as to have the relation n0<omeganN<2omega> (the superscript is the optical frequency to render the refractive index). The thickness of the clad layer 2 does not increase so much even if the working length, i.e., the wavelength length (l) is increased in such a manner. The longer working length is thus attained with the same thickness.

Title: Manufacture of ferrite magnet and housing therefor
Inventor: ANPO TAKESHI
IPC: H01F41/02
Filed: 1983-12-17
Abstract: PURPOSE:To obtain a magnet which has partially high residual magnetism Br and high coercive force Hc in low cost by sintering the band which is required a definite coercive force Hc of a formed ferrite material at a lower temperature than the temperature for the other band. CONSTITUTION:A circular arc 10 is formed with ferromagnetic powder indicated by Mo.nFe2O3 [M is one of Ba, Sr, Pb or Ca and (n) is 4-6.] added with a binder. The band Z1 which is required to have higher Hc of the arc 10 is inserted in the slit 16 of the step 18 of a fire resistant housing 12, a fire resistant lid 20 covers above the band Z1 and the step 18 and sintered at a temperature of 1,150-1,250 deg.C. In this case, the band Z1 is naturally sintered at a lower temperature than the temperature at which an exposed band Z2 is sintered. Consequently, if the thermal transmission of the housing 12 and the lid 20 is appropriately selected, the arc is so sintered that the band Z1 has the maximum Hc and the other band has higher Br.

Title: Channel selection device and receiver using the device
Inventor: MAJIMA ISAO
IPC: H04N5/44
Filed: 1995-09-18
Abstract: PROBLEM TO BE SOLVED: To attain the channel selection of both of television/radio broadcasting by sharing a local oscillation circuit. SOLUTION: A receiver 10 receives television broadcasting and FM radio broadcasting. When a mode is set to a television reception mode by the operation of a key operation part or a transmitter, a local oscillation signal STLO and a television channel signal STCH are mixed, a television intermediate frequency signal STIF is outputted. When the mode is set to an FM reception mode, the local oscillation signal STLO is frequency-divided into 1/2 by a frequency divider 32, the resultant signal is mixed with an FM signal SFCH and the FM intermediate frequency signal SFIF of a frequency 4.5Mhz is outputted.  Therefore, the channel selection of the television broadcasting and the FM radio broadcasting can be performed by sharing a local oscillation circuit 12 for television broadcasting, and further, a voice intermediate frequency filter circuit 61 and an FM detection circuit 62, etc., can be shared. Therefore, cost merit and space merit can sufficiently be realized as compared with the case where a television receiver and a radio receiver are individually provided.

Title: Exhausting device for copying machine
Inventor: SHIMOSE KATSUMI
IPC: G03G21/20
Filed: 1988-09-22
Abstract: PURPOSE:To discharge heat efficiently outside a main body by providing a control part which opens a 1st opening and closing member while an exposing lamp is lit and blocks a 2nd opening and closing member. CONSTITUTION:While copying is awaited, the 1st opening and closing member 61 is blocked to disconnect a 1st flow channel. On the other hand, the 2nd opening and closing member 62 opens to communicate a 2nd flow channel. In this condition, an exhaust fan 1 is driven to discharge heat generating from a fixing device 33 outside the main body together with air flowing in the 2nd flow channel. While the exposing lamp 22 is lit after a copying operation is started, the 1st opening and closing member 61 opens to communicate the 1st flow channel. Simultaneously, the 2nd opening and closing member 62 is blocked to disconnect the 2nd flow channel. Thus, heat generating in the copying machine main body can be discharged efficiently.

Abstract: PROBLEM TO BE SOLVED: To prevent a shock at the time of slewing start regardless of the posture of a working front by changing the travel of a bleed-off valve in response to the reach of the working front calculated on the basis of the detecting value of a posture detecting means. SOLUTION: A relief valve 22 as a main safety valve and a variably operated bleed-off valve 35 are installed to pipelines 20b, 20c branched from the discharge path 20a of a hydraulic pump 20 respectively. The reach arithmetic section of the controller 31 mounted on a working front 3 calculates the front reach (r) of the working front 3 on the basis of angles θ1, θ2 detected by a boom angle sensor 13 and an arm angle sensor 14 and the beforehand stored size of the working front 3. The objective travel of the bleed-off valve 35 is computed on the basis of functional relation, in which objective travel is increased with the reduction of the reach (r) of the working front 3 and the front reach (r). Accordingly, slewing driving pressure corresponding to the reach of the working front 3 at the time of the starting of a revolving superstructure 2 can be set, and a shock at the time of starting can be prevented regardless of the posture of the working front 3.
