Title: Frequency-measuring device
Inventor: HASHIMOTO YUICHIRO
IPC: G01R23/02
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To grasp measured frequency value and traveling direction instantly by displaying not only a plurality of columns of frequency values in digital but also frequency values in analog on a display screen. SOLUTION: The frequency measurement part 11 measures the frequency value of an inputted signal and outputs a digital frequency value. A measurement value sampling part 12 reads a digital frequency value outputted from the frequency measurement part 11 in a specific display period and outputs it. A coordinate conversion part 14 refers to the coordinate data of a frequency axis and converts a digital frequency value outputted at a display period from a measurement value sampling part to coordinate position data on a frequency axis. Then, a digital filter 18 receives the converted coordinate position data, applies a time response characteristic for enabling the fluctuation in the coordinate position data to be recognized easily visually on display, and outputs it to a display control part 19.  A control part 19 displays and outputs a needle for visual confirmation at a position on a frequency axis indicated by coordinate position data on the display screen of a display part 2 and at the same time displays and outputs the digital frequency value being outputted from the measurement sampling part 12 on the same display screen.

IPC: B29C69/02
Filed: 1987-12-24
Abstract: PURPOSE:To obtain a hollow molding in which resin is not intruded into a hollow section of an insert by sealing a diffusing hole before heated and melted resin is solidified, and then covering the outside with a resin material with the molding as the insert. CONSTITUTION:When a gas diffusing tube 5 is extracted from a hole 4 before heated and melted resin is solidified, a hole 8 communicating with nitrogen gas G in the hollow section of a hollow molding is formed on the basis of the tube 5. Then, a slide pin 7 is moved down before the resin is solidified, and the pin 7 thus presses the resin in the hole 4 disposed under the pin, thereby sealing the hole 8 in the hole 4. Thus, an insert 9 as a hollow molding in which the hole 8 communicating with nitrogen gas G in the hollow section is blocked is easily cut at the end of a cylinder 9a formed in the hole 4. The outer periphery of the insert 9 is covered with another resin material 10 of polypropylene. Thus, the molding of a two-layer structure is manufactured.

The length of the light emitting part of a lamp is set 10mm, and the diameter of the reflection mirror for condensing is set 150mm in accordance with the set constitution. As the simulation result of the reflection mirror for condensing which is formed to the shape like the rotary elliptic surface, the illuminance from the center of the liquid crystal board to the peripheral part is increased by about 10% on an average. Thus, the illuminance on the liquid crystal board can be increased by 5-10% irrespective of the distance from the light source to the liquid crystal board.
