Inventor: HASEGAWA HIDEKAZU
IPC: G02B6/28
Filed: 1987-02-23
Abstract: PURPOSE:To facilitate production and to improve reliability by diffracting incident light on a planar waveguide by a curved type diffraction grating formed to one end face of a layer deposited by flame hydrolysis reaction (FHD film) on an Si substrate and guiding the light to an exit side optical fiber through the planar waveguide. CONSTITUTION:The curved diffraction grating 3 is joined to one end face of the planar waveguide 2 on the Si substrate 1 and the fibers 4 are arranged on the other end of the waveguide 2. The incident light 51 on the optical waveguide (planar waveguide) 2 from the incident side optical fiber 54 is diffracted by the diffraction grating 52 and the diffracted light 53 is converged toward the exit side optical fiber 55. Since the convergent position varies with wavelengths, wavelength sepn. and multiplexing are realized. An optical multiplexer and demultiplexer are obtd. when the light incident and exit positions are disposed reverse. The production is thereby facilitated; in addition, the construction is robust and the handling is easy.

Title: Underground heat accumulator
Inventor: TANABE SHIROU
IPC: F24S90/00
Filed: 1982-03-15
Abstract: PURPOSE:To maintain earth in a wetted state by water vapor contained in a heat-transmitting medium passed through a pipe or the like and enhance heat- exchanging efficiency without contaminating earth, by a method wherein a part of a pipe or the like buried underground for exchanging heat is formed from a moisture-permeable water-proof material. CONSTITUTION:Hot water contained in a tank 1 is circulated through an underground pipe 3 by a pump 2, and is returned to the tank 1 after exchaning heat in earth. A part of the wall of the pipe 3 is substituted by a moisture-permeable water-proof material 4 which is not perfectly water-impermeable, that is, it permits molecular water (water vapor) to pass therethrough, although it prevents aggreates of a plurality of water molecules (water) from passing therethrough. Accordingly, the water vapor contained in the heat-transmitting medium being circulated permeates through the pipe part formed of the moisture-permeable water-proof material 4 to maintain earth in a wetted state, so that heat is favorably transmitted without contaminating earth.

Title: Switching regulator
Inventor: ABE NOBORU
IPC: H02M3/28
Filed: 1985-02-28
Abstract: PURPOSE:To increase the regulating range of an output voltage by adding a transistor member for bias to a saturable reactor to move the hysteresis loop of a core to an apparently high side. CONSTITUTION:A pulse signal of the prescribed frequency is applied to the base of a main switch element 3 to operate switching, the voltage induced at the secondary winding N2 of a main transformer 2 is controlled by a saturable reactor 4 to the prescribed voltage and output. This control is performed by inputting the detection signal Vs of an output voltage V0 to a controller 12 formed of an error amplifier, and flowing a reset current through a control switch element 10. In this case, the reactor 4 is formed by providing a permanent magnet at part of the core on which a coil is wound as a magnetic bias. Thus, since the remaining magnetic flux density of the core is disposed apparently at the position of Br', the initial magnetic flux density of the core can be regulated between the saturated magnetic flux density and Br', to increase the control range of the output voltage V0.

Title: Power amplifier
Inventor: IGUSA TAKAAKI
IPC: H03F3/30
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To easily and surely secure the high output and prevent the breakdown of elements for a power amplifier that is used at a comparatively low power voltage level by preparing a comparator which compares the boosting voltage given to a preceding stage drive circuit from a booster circuit with a prescribed reference voltage level and applying the negative feedback control to the output voltage of the booster circuit at a fixed voltage level by means of the output of the comparator. SOLUTION: The boosting voltage V1 drops in response to the increase of current consumption I1 of a preceding stage drive circuit 12. However, when the voltage V1 is lowered down to the prescribed reference voltage Vs or less, the 2nd voltage Vp added to the charging voltage or a 1st capacity element C1 by a negative feedback control circuit 7 rises to heighten the boosting drive level of a booster circuit 3. Thus, it's possible to prevent the decrease of the voltage V1 applied to the circuit 12 and to keep the voltage V1 at a constant level even in a large output mode when the consumption I1 of the circuit 12 increases. Furthermore, the rise of the voltage V1 is prevented and the V1 is kept at a constant level even in a small output mode when the consumption 11 decreases.

Filed: 1988-02-23
Abstract: PURPOSE:To reduce the material feeding number and to control the ion beam generating amount by providing plural numbers of ion source storage chambers and changing the diameter of orifices of the chambers partially or altogether. CONSTITUTION:Ion source 7 in storage chambers 1-6 are heated by a filament 9 and evaporated, and then it flows in to an ionization surface 12 through orifices 8.
