Title: Capacitive electromagnetic flowmeter
Inventor: SAKURAI YUTAKA
IPC: G01F1/58
Filed: 1992-09-30
Abstract: PURPOSE:To obtain a capacitive electromagnetic flowmeter in which fluctuation of output due to external vibration is suppressed. CONSTITUTION:A measuring pipe 1 is supported through viscoelastic members such as 0-rings 10a, 10b, 12a, 12b on a casing member 2. Magnetic components, e.g. a coil 3 and a core 4, are secured to the casing member 2 while spaced apart from the measuring pipe 1. Liquid-tightness is kept between protective rings 6a, 6b and the measuring pipe 1 through the O-rings 12a, 12b. Resonance frequency is increased because equivalent mass is reduced at the part vibrating integrally with the measuring pipe 1 and fluctuation of output due to vibration is suppressed because the protective rings 6a, 6b are isolated and vibration of the measuring pipe 1 is reduced.

Abstract: PURPOSE:To highly efficiently execute receiving and delivering work by providing a receiver for processing an information signal after retrieval and a transmitter for reading the processed information signal through a reading means to issue an electromagnetic wave to a communication repeater, and driving the receiver and the transmitter through separate driving means. CONSTITUTION:The receiver 2 of a retrieving device 1 is provided at a desired spot on a part shelf in a storehouse, and a transmitter 3 is always carried by a part retrieving man. When a retrieving signal which is expressed by infrared ray 12 and has the same code as a preset one is given through a communication repeater 15 on a storehouse ceiling from a host computer 13 to the receiver 2 on a part shelf where a part desired to be retrieved is stored, the emission section 5 of the receiver 2 coinciding in the code emits light. The number of delivered and received parts is indicated on the display section 6 of the receiver 2, but for instance in the case where the part retrieving man receives and delivers the parts somewhat more or less, the number of parts indicated on the display section 6 is corrected by the input section 7 of the receiver 2. Since the transmitter is set on the receiver 2, the transmitter 3 can read the above corrected information. The transmitter 3 issues an information signal corrected by the infrared ray to the communication repeater to input it into the hostcomputer 13.

Filed: 1984-12-14
Abstract: PURPOSE:To adjust refractive index between the main agent and bride agent which form a bonding agent in order to prevent generation sparcle and improve picture quality by using unsaturated ester as the bride agent of bonding agent which is used for bonding a non-reflective transparent plate to the face plate portion. CONSTITUTION:The bonding agent 3' used for bonding the non-reflective transparent plate 4 to the face plate of CRT contains unsaturated polyester main chain (refractive index: 1.50) as the main agent, stylene (refractive index: 1.54) as the bridge agent and unsaturated ester which has double coupling within the molecules (refractive index: 1.45). Thereby, polymerization of only the discrete stylene is prevented, production of polystylene (refractive index: 1.55 or more) is interfared and stylene and unsaturated ester are polymerized. As a result, the refractive index of this polymer becomes about 1.504 and it is adjusted to a value near to the refractive index of 1.50 of the unsaturated polyester main chain. Therefore, difference of refractive indices within the bonding agent 3' can be eliminated, generation of sparcle generated by difference of refractive indices can be prevented and high quality picture can be obtained.
