Title: Signal injecting device for distribution line
Inventor: SHIROKURA HIDEYUKI
IPC: H04B3/56
Filed: 1979-06-13
Abstract: PURPOSE:To ensure the steady injection of the FS (Frequency Shift) signal, by setting the high-low resonance frequency of the FS signal coupling circuit to be supplied to the distribution line to the prescribed state and thus securing the coincidence for the injected current in case the signal frequency is switched in order to reduce the transient phenomenon. CONSTITUTION:In case the FS signal is injected to distribution line 4, the coincidence is secured between the resonance frequency decided with constants L2 and C2 of the distribution coupling circuit. At the same time, the resonance frequency decided with constants L1 and C1 is set higher sufficiently than the signal band. The gate frequency of the FS signal is switched by transmission code generator CIN, and gate signals G1 and G2 are applied alternately to thyristors T1 and T2. Thus the FS signal is injected. In this case, frequency fH' to give the current value equal to current IL in the case of frequency fL is referred to as new fH for the signal injection current/signal frequency characteristics curve. And then the coincidence is secured for the injected current in case the frequency is switched.

Title: Extremely small material testing instrument
Inventor: YAMAMOTO YASUNORI
IPC: G01N3/40
Filed: 1986-03-31
Abstract: PURPOSE:To measure material dynamical parameters such as a fine rupture strength and a fracture toughness value by controlling a variable loading means which places a very small load optionally according to the output of an AE detecting means. CONSTITUTION:A DC current is supplied from a measurement controller 12 to an electromagnetic coil 3 and the load is increased or decreased with the electromagnetic force of the electromagnetic coil 3 by the direction of the current to increase or decrease the load placed on a sample 7 mounted on the stage 9 of a sample table 8 through an indenter 6. While the load is placed, displacement on the surface of the sample 7 by the indenter 6 is detected by a displacement detector 5 and sent as displacement information to the measurement controller 12 through a displacement measuring instrument 10. If deformation sound or cracking sound generated when the sample 7 is pressed by the indenter 6 to deform is detected by the AE sensor 18, on the other hand, its detection signal is sent to the measurement controller 12 through a preamplifier 19 to stop the loading.

IPC: G11B20/10
Filed: 1994-04-13
Abstract: PURPOSE:To apply PLL synchronizing a regenerative signal with a regenerative clock with simple constitution by changing a phase of a reference clock according to a phase difference between the regenerative signal and the regenerative clock. CONSTITUTION:In a reproducing mode, a changeover switch 14 is shifted to an (a) side by a control signal 207. The regenerative signal 201 regenerated from a recording medium is digitized by an A/D converter 202 at the period of the regenerative clock to be inputted to a phase difference detection circuit 13 in a PLL circuit 12 through a waveform equalizer circuit 203. The circuit 13 detects the phase difference between the regenerative signal and the regenerative clock, and a programable delay element 5 switches a delay amount according to the phase difference data. A clock signal shifting the phase of the reference clock 206 according to the phase difference is outputted as the regenerative clock 210, and the regenerative signal 201 is sampled by the clock 210 to be digital converted, and the PLL is applied.

Title: Electrostatic transducer
Inventor: ZINSERLING BERT DIPL ING
IPC: H04R1/22
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To improve a reproduced quality, compared with a transducer utilizing electrodynamics by arranging a transducer film inside of a housing in the shape of a tube at a specific angle so as to obtain high acoustic pressure for reducing the main resonance of the film. SOLUTION: A transducer film 3 is arranged inside of the tube-shaped housing 2 diagonally at 30 to 90 degrees, desirably 60 degree with respect to a cross section Q. Then, depending on the angular arrangement of the film 3, the film surface becomes relatively large with respect to the cross section of the housing, to obtain high acoustic pressure for reducing the main resonance of the film. In addition, an electrode 4 is arranged on both sides of the film 3 to apply a regulated signal voltage satisfying a safety reference. In addition, the main resonance of the film is attenuated by inserting packing such as wool, cotton into the housing 2 as an attenuating means. Thereby the reproduced quality is improved, compared with the transducers utilizing magnetism and electrodynamics.

Title: Method for exchanging electronic part
Inventor: FUKAZAWA HIDEYUKI
IPC: H05K3/22
Filed: 1997-03-27
Abstract: PROBLEM TO BE SOLVED: To exchange electronic parts, such as PGA parts, etc., by directly efficiently heating the soldered joint of the parts by attaching a hot blast guiding plate and a hot plate partitioning plate to electronic parts when it is difficult to directly heat the soldered joint. SOLUTION: Since a hot blast guiding plate 3 and a hot blast partitioning plate 4 are attached to electronic parts 2 and a hot blast is fed from a hot blast nozzle 5, the soldered joint 9 of the objective parts 2 can be heated directly and the parts 2 can be exchanged with another parts without melting the soldered joints of adjacent electronic parts. Therefore, even when it is difficult to directly heat the soldered joint 9 of the parts 2 with the hot blast, the parts 2 can be exchanged with another parts without deteriorating the connection reliability of the adjacent parts, because only the soldered joint 9 of the parts 2 can be heated directly.

IPC: H01S5/026
Filed: 1989-03-29
Abstract: PURPOSE:To obtain laser rays excellent in quality with a low power consumption without any mode separation and mode hopping by a method wherein many active layers formed in fine lines are arranged at a prescribed interval. CONSTITUTION:Active layers of quantum well structure are arranged on a clad layer, where the active layers are constituted in such a manner that many active layers 2-1, 2-2,... formed in fine lines whose widths are smaller than the de Broglie wavelength of electrons are arranged at a prescribed, accurate interval to serve as quantum fine lines. An interval of A at which the fine line active layers 2-1, 2-2,... are arranged is set to be a length proportional to an integer multiple of a half of oscillation wavelength lambda. Therefore, the fine line active layers 2-1, 2-2,... function as not only an active layer but also a tuner. By this setup, in a semiconductor laser of this design, a threshold current can be decreased by effectively trapping a current to realize a low power consumption, and a tuner for distributed feedback is concurrently formed, so that semiconductor laser rays of single wavelength excellent in quality without any mode separation and mode hopping can be obtained from a semiconductor laser of this design.

Title: Temperature control system of thermal recording head

Filed: 1987-03-31
Abstract: PURPOSE:To achieve rapid printing operation without increasing the capacity of a supply power source, by arranging a heat generator and a temp. detector in the state adjacent to or brought into contact with a recording head and heating the recording head so as to bring the temp. thereof to a definite temp. range. CONSTITUTION:Four thermostats S and four plate-shaped heaters H are provided to the back surface of a thermal head and the contacts of the thermostats S1-4 are turned ON at 30 deg.C for less and turned OFF at 30 deg.C or more. Since the thermostats S are turned ON at the time of standby and at the time of low temp., the heaters H generate heat to heat a recording head. Four pairs of the thermostats S and heaters H are mounted in a state divided into four blocks in order to be capable of controlling heating at every block since only a part of the recording head rises in temp. when specific content is recorded. When the temp. of the recording head rises during printing, the thermostat SN is turned OFF and the heating of the part thereof is stopped. When the thermostat SN is cooled, it is automatically turned ON to again perform heating operation. Since the recording head part can be held to a definite range of temp., trouble such that printing density is low at the time of low temp. can be removed.
