Title: Antenna device
Inventor: MATSUO MASAYUKI
IPC: H04B1/18
Filed: 1991-06-25
Abstract: PURPOSE:To avoid malfunction due to the effect relating to communication such as fading by correcting a resonance frequency even when the resonance frequency of an antenna is deviated so as to eliminate the effect onto the actual use possibly. CONSTITUTION:The device is provided with a signal generator 3 generating a signal with a frequency for checking frequency deviation and also a signal level detector 4 detecting a level of a reflection signal from an antenna 1. An output voltage from a variable power supply 7 is superimposed on the antenna 1 to correct a resonance frequency. The antenna 1, a directional coupler 6, a circulator 5, the signal level detector 4, the variable power supply 7 and the antenna 1 form a feedback loop to vary a voltage superimposed onto the antenna 1 by feedback control thereby eliminating the deviation in the resonance frequency of the antenna 1.

Title: Driving device for sand pile
Inventor: KURIMOTO NAKATOMI
IPC: E02D3/10
Filed: 1980-10-29
Abstract: PURPOSE: To more firmly tamp sand pressed closely in an outer cylinder, by a method wherein a hydraulic cylinder for driving inner cylinders is mounted at the upper end of the outer cylinder, is secured through the piercing of the hollow piston rod of the hydraulic cylinder through a lower of a vibrator.  
     CONSTITUTION: Through the movement of a piston rod 2b to an upper limit position with a hydraulic cylinder 2 for driving inner cylinders actuated, vibration transmission means 20 and 22 are brought into an engaged state to monolithically unite a vibrator 4 with an outer cylinder 1. After the outer cylinder 1 and an inner cylinder 5 are inserted into a ground with the vibrator 4 operated, sand is charged through a hopper 9 into the outer cylinder 1. The vibrator 4 is disconnected from the outer cylinder 1 to vertically vibrate only the inner cylinder. Meanwhile, the upper limit position of the stroke of the hydraulic cylinder 2 is set at a somewhat lower level than that of the initial position, and the piston rod 2b is elevated to the extent that the vibration means are brought into no engaging state. This causes the inner cylinder 5 to vertically move independently from the vertical movement produced by the vibrator 4. The outer cylinder 1 is pulled off gradually as sand in the outer cylinder 1 is tamped by the inner cylinder 5.

Title: Optical control switch device for traveling object
Inventor: OOSHIMA SHINTAROU
IPC: G01V8/20
Filed: 1983-08-24
Abstract: PURPOSE:To obtain an assured optical control output despite the fluctuation of the indoor light or the natural light by using an amplifier which produces the clear output voltage of high and low levels and has both ON and OFF switch states. CONSTITUTION:If a main photodetecting element D1 gets into a shadow between time points t1 and t2, the terminal voltage VD is negative. At the same time, the input voltage V1 also becomes negative and set at a level lower than the reference voltage VS from a level higher than the VS. Therefore the output voltage V0 is chged to a high level from a low level. Then the area between output terminals S and S' is kept off for a period between 0-t1 and then kept on for a period between t1-t2 respectively if a switching transistor TS is connected to the output terminal. In other words, the capacity is obtained to flow a current to the terminal S' from the terminal S. While the voltage VD is kept positive for a period between t3 and t4 when a compensating photodetecting element D2 is kept within a shadow. At the same time, the voltage V0 is set at a low level and the area between terminals S and S' are kept off. Therefore the area between S and S' is kept on only in the period between t1-t2.

Title: Antenna for automobile and its manufacture
Inventor: TAGUCHI MINORU
IPC: H01Q1/32
Filed: 1990-06-14
Abstract: PURPOSE:To eliminate a wind noise stably and surely independently of the direction of wind the antenna, to attain ease of manufacture and to reduce the antenna comparatively inexpensively by providing a noise silencing means. CONSTITUTION:A spiral body 32 made of a hard steel wire which is a wind noise silencing member is wound and fixed to an outer circumference of a rod antenna element 31 of an antenna 30. Comparatively much turbulence is produced to wind on an outer circumference of the antenna 30 by the action of a spiral 32 made of a hard steel wire for generating turbulence. Thus, a low atmospheric pressure region produced locally on the outer circumferential face at the leeward side of the antenna 30 is disturbed by turbulence and diffused and vanished. As a result, minute vibration of the antenna 30 due to the low air pressure region which causes antenna wind noise is suppressed to silence the noise. Since the material cost of the hard steel wire is low and the manufacture is comparatively easy, the entire antenna is manufactured comparatively and inexpensively.

Filed: 1986-07-01
Abstract: PURPOSE:To enable an ink adhered to the surface of nozzle holes to be removed while preventing dust or the like from adhering to the nozzle holes and preventing treated water-repellent parts near the nozzle holes from being damaged, by treating the entire peripheries of the nozzle holes with a material having a surface energy lower than that of the texture of the nozzle hole surface, leaving the nozzle hole surface texture on the outer side, and surrounding the texture with a similar material in the form of keyholes. CONSTITUTION:A head substrate is made from, for example, an ABS resin, and is provided with parts 10 treated to be water-repellent by using a fluoro polymer. The surface energy of the ABS surface is 40-50dyn/cm, while that of the water-repellent parts is 10-18dyn/cm. An ink adhered to the surface of the nozzle holes collects at an ABS surface passage part 11 due to the difference in surface energy, and accumulates in a liquid pool part 12 under gravitational forces. For example, when a mechanism for bringing a water-absorbing member into contact with only the liquid pool part is provided at a home position of a carriage of a printer, the adhered ink can be removed without damaging the water-repellent parts near the nozzle holes and without causing adhesion of dust to the nozzle holes.
