Abstract: PROBLEM TO BE SOLVED: To enable easy detection of a state of a through-hole of a suction nozzle and absence or presence or a suction state of a chip-like circuit part in a suction port of the through-hole at the tip of the nozzle. SOLUTION: This chip-like circuit part suction head includes a box 42 having therein a vacuum chamber 41 whose pressure is made negative by a vacuum- drawing means, and suction nozzles 31 mounted in a lower side of the box 42 and whose tip ends are projected from the box lower side. The nozzle 31 is passed through the box lower side. Each nozzle has a through-hole 31a for air suction which is open to a suction port 39 at a tip end of the nozzle 31. Provided inside the box 42 is a light source 43, which consists of a planar luminous member for directing light towards the suction port 39 through the through-hole 31a. A light receiver 76 is provided on a side of the suction ports 39 of the nozzles 31.  On the basis of the presence or absence of light leaked and received from the suction port 39 of the through-hole 31a of the nozzle 31, the pressure of absence of a closed state of the through-hole 31a of the nozzle 31 is checked.

Title: Suction port for electric cleaner
Inventor: OOGOSHI KENICHI
IPC: A47L9/02
Filed: 1978-05-29
Abstract: PURPOSE: To obtain a suction port which is simply structured, slides smoothly even on a carpet floor and can remove easily even waste thread and so on, by forming a slope, whose rear part points upward, at the rear of a backward curve part of a suction port, and by providing protrusions at the slope.  
     CONSTITUTION: A backward curve part 31 is located behind a floor brush 8, and a slope 32, whose rear part points upward, is situated further behind the brush 8. Protrusions 33 are arranged on the slope 32 along the direction in which a dust suction port and a suction groove 5 are arranged. In the case of cleaning a carpet floor, the floor brush 8 is pulled in. In the event of waste thread and the like being entangled with carpet thread, the front of the sucton port is lifted up so that the slope 32 can become parallel to a floor surface, and the waste thread and the like will be removed as a result of being scratched off by means of the protrusions 33. At that time there is no friction resistance between the suction port and the floor surface, and thus, a force, which is needed for sliding of the suction port, can be relatively small.

Filed: 1980-05-15
Abstract: PURPOSE:To satisfy the noise margin standard, by lowering the level of an undesired wave in case the undesired wave has been mixed into the band in which a piolt signal is used. CONSTITUTION:The output of a signal common amplifier 1b is applied to the signal detecting parts 2'-1-2'-n as well as to a rectifier 1c. With an input of an undesired wave, the DC output level of the rectifier 1c increases to generate an output from a level comparator 1d. The output of the comparator 1d is supplied to a variable gain amplifier 2-1b' to lower the gain of this amplifier. In such a way, the level of an undesired wave emerging at the output of a narrow band pass filter 2-1a is reduced.

A pH indicator is then added along with an appropriate quantity of alkaline for rendering the analytical sample weak acid. Subsequently, a sample solution is injected into an electrodeposition cell 1 and the impurities are deposited on the electrode 2 by electrodeposition. Radioactivity is determined for the impurities and tracer by measuring the radioactivity for the electrode and the impurities are determined with reference to the radioactivity of tracer.  Consequently, the impurities can be separated from phosphate matrix and a filmy measuring sample can be prepared.
