IPC: A47J41/00
Filed: 1988-09-28
Abstract: PURPOSE:To obtain hot water boiling always at a high temperature by providing the inner peripheral surface of a liquid storing chamber with a pressure sensor working when a liquid storing chamber internal-section comes to set pressure with vapor generated at the time of the boiling of contained liquid, and controlling the electrification of a heater. CONSTITUTION:On the inner peripheral surface of a vapor chamber 3a, the pressure sensor 23 of a diaphragm type is set. Directly before coming to a boiling state, much vapor S is generated in the vapor chamber 3a, and internal pressure is heightened, and when it reaches the working setting pressure of the pressure sensor 23 set in the vapor chamber 3a, then the pressure is detected, and the electrification of a water boiling heater 5a is controlled to be turned OFF. After that, the temperature of contained liquid W is retained only by heating a temperature retaining heater 5b. When the internal pressure is made lower than the working setting pressure of the pressure sensor 23 along with the slight lowering of the temperature of the contained liquid W, then the lowering of the pressure is detected by the pressure sensor 23, and the water boiling heater 5a is electrified, and the contained liquid W is heated again to be boiled.

Title: Vessel for detecting electrochemical emission
Inventor: TANAKA TAKASHI
IPC: G01N21/76
Filed: 1989-09-21
Abstract: PURPOSE:To lessen the required volume of a soln. to be detected by holding the soln. to be detected between an insulating flat plate and a light transmittable flat plate and causing the emitted light generated near a working electrode to arrive through the light transmittable flat plate with a shorter optical path length at a photodetector. CONSTITUTION:The soln. to be detected is held between the insulating flat plate 12 and the light transmittable flat plate 13 by surface tension at the time of pulling up a vessel 10 for detection from a container contg. the soln. to be detected. This vessel 10 is not a cylindrical vessel but is a parallel vessel of a narrow spacing and, therefore, the required volume of the soln. to be detected is smaller. The light emitted near the working electrode WE passes the light transmittable flat plate 13 and arrives at the photodetector 6 with the shorter optical path length. Since there are no obstructions on the flat plate 13 side, the flat plate 13 and the detector 6 can be positioned extremely near to each other. The quantity of the light received on the photodetecting surface of the detector 6 is, therefore, increased and the detection sensitivity thereof is improved.
