Title: Oscillator and communication equipment
Inventor: FUJII YASUO
IPC: H04B1/38
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To provide oscillator stable in characteristics by using a fixing member butted to the inside face of the cap of a package for fixing the position of the cap, and for stabilizing the passage of ground currents. SOLUTION: At the time of putting on a cap 12, end parts 61a and 61b of a fixing member 60 have elasticity, and linear end parts 62a and 62b have rigidity so that the sawtooth-shaped end part 61a can be bent downward so as to be butted to the inside face of the cap 12, and the linear end part 62b can be butted to the inside face of the cap 12 without being bent. Then, the cap 12 receives a force from the inside face by the fixing member 60 so that the position of the cap 12 can be fixed. Therefore, even when the cap 12 is took off each time the arranging position of a resonator 20 or a circuit board 40 is adjusted, and the cap 12 is put on again after the adjustment, the position of the cap 12 can be always made constant. Also, the ground electrode of the circuit board 40 is connected through the fixing member 60 with the cap 12 by using the metallic fixing member 60.

Title: Fluid spray method
Inventor: EBI YUTAKA
IPC: B41J2/02
Filed: 1980-10-10
Abstract: PURPOSE:To obtain a fluid spray method which does not form unevenness in an interval between liquid droplets with a simplified installation without use of any vibrator, by periodically charging an electric field to a fluid forcedly fed to a fluid spray nozzle in an ink jet sprayer or the like. CONSTITUTION:Ink forcedly fed to an ink jet head 1 by a pressure P0 receives a power F defined by F=agradE<2>, when an electric field E is generated between the first electrode 2 and the second electrode 3. An electric field such as an A.C. sine-wave electric field periodically changed by an A.C. power source is charged between the electrodes 2 and 3. The diameter D1 of an ink stream-passing hole in the electrode 2 is larger than the diameter D2 of an ink stream-passing hole in the electrode 3, so that a power DELTAP=a'grad(Ecoswt)<2> along a direction shown as the arrow B is applied to the ink stream by the electric field. Consequently, an ink pressure inside the head 1 slightly changes with frequency in response to the frequency of the electric field, and divides an ink liquid column 6 to be sprayed into ink droplets 7.

Title: Reversible information display medium
Inventor: ASADA SEIICHI
IPC: B41M5/36
Filed: 1992-06-02
Abstract: PURPOSE:To widen the temp. range for printing of a reversible information display medium for heat recording with heat or light so that the medium can be easily used by forming a shape-memory resin layer on a light-absorbing layer or a light-reflecting layer. CONSTITUTION:A shape-memory resin layer 3 is formed on a light-absorbing layer 2 on a transparent substrate 1. The surface of this shape-memory resin layer is deformed to have a fine rugged surface so that the surface scatters light near the glass transition temp. and that the surface looks white by scattering of light when no information record is given. Only the area heated to a higher temp. than the glass transition temp. by a thermal head is flattened and colored into the color of the light-absorbing layer 2. When the resin layer is treated by calendering at specified temp. and rapidly cooled to room temp., the recorded information is erased. Thereby, printing can be performed at 60-15 deg.C and the medium can be repeatedly used.

Title: Frequency detection controller
Inventor: FURUYA MUNEHISA
IPC: G01R23/165
Filed: 1986-06-18
Abstract: PURPOSE:To enable the prevention of erroneous calculation of frequency even when a signal with a larger amplitude is inputted, by comparing the amplitude of video signals at various channels with an omnivideo to judge the significance of the center channel. CONSTITUTION:Outputs of (n) band pass filters are inputted into an A/D converter 2 and in a specified time after the time at which a signal above a fixed level is detected a control circuit 3 operates PAU, PAO and PAL registers 4 to store output levels of own channel and both adjacent channels. A comparator circuit 13 validates an Fp signal indicating the center channel when the requirement of PAU<=PAO>=PAL is met. On the other hand, an omni comparator 11 outputs a channel validation signal 12 to a comparator circuit 13 when the video signal of a channel is larger than an output of a filter, the pass band of which covers the total pass band of the (n) filters. Then, a frequency computation circuit determines the frequency using the PAU, PAO and PAL at the center channel.
