IPC: H03H9/05
Filed: 1978-11-20
Abstract: PURPOSE:To decrease greatly the working processes for the fixture of the crystal bar as well as to increase the intensity of the shock resistance by inserting the end part of the crystal bar directly to the concavity provided to the plug substance and then fixing it. CONSTITUTION:Crystal bar 15 is fixed by providing ribbon-shaped metal material 18 to the concavity of plug substance 16 into a socket shape and then inserting the end part of bar 15 into the concavity directly. Furthermore, the plug-in part of a socket shape doubles the support of bar 15 and the electrode route. As a result, the working processes can be reduced greatly for fixture of the crystal bar, and at the same time the electrode route is shared for both the lead terminal and the crystal bar at the fixed area to omit any other conduction means. Also, the intensity of the shock resistance can be increased since the fixed area functions as the buffer to the shock.

A coincident information generating section 2 gives an instruction of color adjustment to the user based on the reference color information and stores and outputs the coincident information obtained as a result. A correction processing section 3 finds a conversion coefficient for color conversion based on the coincident information and performs color conversion of the color input image via the color conversion processing section 16 and the result is sent to the display section 18.  Thus, a color of an image displayed on the display device is in matching with a color of a printed matter.

Abstract: PURPOSE:To detect the degree of compaction of pulverized materials in a storage tank by such an arrangement wherein on both sides of the storage layer of a pulverized material container, a sound wave oscillator and a sound wave receiver are arranged opposingly and the sound attenuation characteristic of oscillated sound waves until they are received passing through the pulverized material storage tank is utilized for detection. CONSTITUTION:Partition walls which do not hamper the passage of sound waves, e.g., porous plates, are provided at proper positions in the vicinity of the discharge hole 2 of a pulverized material container, and a sound wave oscillator 4 and a sound wave receiver 5 are arranged opposingly. The oscillator 4 generates random noises such as white noise, pink noise, etc., and sound waves which pass through P layer of pulverized materials and are detected by the receiver 5 are measured and the sound attenuation characteristic of sound waves at the time of passing through Player is set at an overall level or a specific band level. Based on a calibration obtained in advance, the degree of consolidation or the amount of its change of P layer of pulverized materials is calculated. A critical degree of compaction at which the difficulty of discharge takes place is measured in advance, and an action for alleviating consolidation is to be taken before this critical degree of consolidation is reached, and by this procedure, an accident of clogging of the discharge hole can be prevented.
