At this time, an internal shell needle 5 is pierced at a location on the skin of a patient where a blood vessel is estimated. When a needle tip 51 has penetrated the skin by advancing the piercing, a negative pressure is applied while pulling into a plunger 13 through a knob 14 of a syringe 11. Then, when the needle tip 51 is inserted in the blood vessel, the blood in an internal cavity is sucked into the internal shell needle 5 by the negative pressure. As a result, the sucked-in blood flows into the plunger 13 through the internal cavity of a main tube 3 of a transparent housing 2 from a side hole 52 of the internal shell needle 5.  By seeing through the stream of the blood, the piercing of the internal shell needle 5 into the blood vessel is judged.

Abstract: PURPOSE:To enable to store the water having a temperature, which realizes hot water supply for a short time, in the upper portion of a hot water supply tank and consequently to cope with a suddenly developed hot water supply load by a structure wherein a heating heat exchanger, through which heat transfer medium circulates, is provided in the upper portion of the hot water supply tank and at the same time a circulating circuit if stored hot water to communicate the upper part of a tank wall with its lower part is provided. CONSTITUTION:When hot water storage operation is performed, because of a condenser 2 being arranged in the upper portion of a hot water supply tank 1, only the stored hot water in the upper portion is heated. Accordingly, under the condition that the circulating of stored hot water 11 by a circulating pump 13 is stopped, the temperature of the stored hot water in the upper portion of the hot water supply tank is so quickly raised that the certain fixed amount of hot water can be held. Consequently, the state to enable to cope with the unexpected hot water supply load is established. In order to heat the whole amount of stored hot water, the circulating pump 13 is put into operation so as to lower the water to be heated by circulating from the upper portion to the lower portion in the hot water supply tank.

IPC: H04W16/08
Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To uniform the quality of communication and to improve the efficiency of the whole system by calculating communication quality at the discrete time based on the total power of received signals and the average of the received power of incoming information signals, and adjusting the number of mobile stations while increasing the number of mobile stations to be managed when the communication quality is excessive and reducing the number of the mobile stations to be managed when the communication quality is bad. SOLUTION: A total receiving power observing part 2 observes and outputs the total power of signals received at the time of discretizing (i). An information signal receiving part 3 calculates the average of the received power of the upward information signal transmitted from each mobile station at the time of discretizing (i) to output as a signal power S. A communication quality arithmetic part 4 calculates the quality of communication at the time of discretizing (i) based on the total received power outputted by the part 2 and the signal power S outputted by the part 3. The transmission power of a pilot signal is controlled based on this quality of communication.

Title: Wavelength monitor controller for wavelength division multiplex optical transmission system
Inventor: VILLENEUVE BERNARD
IPC: H04B10/564
Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To provide a small sized wavelength monitor controller which is integrated in a small sized semiconductor laser package preferably and applicable to a wavelength division multiplex optical transmission system. SOLUTION: A non-collimate light emitted from a laser emission/divergence source 12 transmits through a filter element 18 and directed to two photodetectors 20, 22 located apart closely. In order to make the wavelength stable, different outputs from the two photodetectors 20, 22 are used for a feedback loop to make the wavelength of the laser emission divergence source 12 stable to a desired object wavelength. Since a wavelength transmission rate of a Fabry-Perot etalon depends on an incident angle of an incident beam, various wavelength bands emitted from the laser stimulation divergence source 12 are converted into different transmission losses to the two photodetectors 20, 22 and then a wavelength change is detected as a different power change.
