Title: Transmission line
Inventor: YOSHII YASUSHI
IPC: H01P3/08
Filed: 1987-03-12
Abstract: PURPOSE:To obtain a line with low characteristic impedance without increasing line width, by forming a groove so that a substrate thickness is made thinner than ordinary substrate thickness on the surface of a semi-insulated compound semiconductor substrate equipped with a ground conductor on a rear plane, and forming a conductor line in the groove. CONSTITUTION:The semi-insulated compound semiconductor substrate 1, a microstrip line 2, and the ground conductor 4 are thc same components as used in a conventional device. The groove 5 is formed on the main plane on one side of the substrate 1 by digging the plane from one plane of the substrate 1, and the substrate thickness of the part is formed thin, and the conductor line 13 is formed in the groove 5. Since the characteristic impedance of the line 3 with low impedance can be decided by a ratio of the line width to the substrate thickness if the dielectric constant of the substrate 1 is kept constant, it is possible to form a transmission line with low characteristic impedance without increasing the line width by forming the conductor line 13 in the groove 5.

Abstract: PURPOSE:To prevent rapid charge of power source frequency by detecting the frequency and phase of an emergency power source, which is operated synchronously with a commercial power source, so as to maintain them within the standard values, and oscillating standard frequency when the power on one side of power sources has stopped. CONSTITUTION:The voltage of a commercial power source is detected with PT301, and the voltage of an emergency power source with PT302, and those are input into the CPU5 through comparations 302 and 304. CPU5 counts phase difference between the two voltages, and compares it with the standard value, and if it is within the standard value it outputs output frequency f as it is, and if it is over the standard value it sets output frequency f anew. This processing is repeated until the phase difference is settled with in the standard. If the power stoppage on one side of the power sources is detected 306, CPU305 outputs standard frequency f, and an output signal in proportional to the data of the frequency f is sought from a timer 7 by subtracting it with the clock signal of the timer 7, and is divided 308 so as to obtain desired frequency. Hereby, rapid change of the frequency at the time of service interruption and recovery from it can be prevented.

Title: Tail plug of writing implement or the like
Inventor: FUKUDA MASAO
IPC: B43K3/00
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce to the utmost the possibility that an infant puts a tail plug in his mouth and a respiratory organ such as a throat is choked therewith, by forming a hole for preventing suffocation in a wall part so as to ensure an air passage. SOLUTION: In respect to an oil-based ink ball-point pen having a cap, a vent for preventing suffocation is formed in the cap. Since the cap is not needed on the occasion of using the writing implement, it is fitted on the tail plug 4 side of the writing implement. In the case of the implement of which the tail plug 4 and the cap are connected together on the occasion, the tail plug 4 sometimes happens to be fitted with the cap in a state wherein the tail plug is disengaged from an exterior body 1. Then there occurs the possibility that an infant or the like swallows accidentally the tail plug 4 and the cap being connected, since they are small relatively.  Accordingly, a vent 8 is provided in the tail plug 4 so that it may communicate with the vent of the cap on the occasion when the cap and the tail plug 4 are connected together and that an air passage may be ensured thereby as a whole.

IPC: G01B11/02
Filed: 1986-03-18
Abstract: PURPOSE:To accomplish improvement of measuring accuracy by defining a reference point on a specimen by means of a sensor unit which senses a light beam radiated onto the specimen placed on a table and measuring dimensions of the specimen by its distance of travel. CONSTITUTION:In order to measure a length of the transversal width of a specimen, the specimen A is set in an offset position from an optical axis CO of a microscope 7. Further, prior to this setting, the focus (o) of the microscope 7 is set in a position flush with the top surface of the specimen A. And, when a light beam 9 is radiated from a light-flashing unit 8, the beam lights up the top surface of a table 5 and as a reflected light beam of the beam 9 does not reach a sensor unit 10, the sensor 10 does not produce any output. Next, when the X-axis travelling bench is operated for displacing the table 5 in the X-axis direction, an end surface of the specimen A reaches the optical axis ao-line of the beam 9 and an output signal is produced by reception of the reflected beam of the beam 9 by means of the sensor unit 10. Further, displacement in the X-axis direction makes reception of the reflected beam of light 9 of the sensor 10 impossible, and consequently, the above output signal is suspended. In the mean time, as a counter unit sends the travelling distance as an electric signal. The dimension of length l of the transversal width of the measuring unit is displayed on a display unit 11.
