Title: Transparent ice and its manufacture
Inventor: DESHIMARU KAZUNORI
IPC: F25C1/18
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To reduce an icemaking cost of transparent water by dipping an ice can filled with raw material water at as a low flow rate of dissolved oxygen as possible in a cooling medium by an aerating means, and freezing the water. SOLUTION: Potable water 1 is not used as its raw material water, but dissolved oxygen of the water 1 is reduced as much as possible by an aerator 2, and the raw material water 1' having the dissolved oxygen amount of 3 ppm or below is made. Then, the water 1' is filled in an ice can 3, the can 3 is dipped in a low-temperature brine at about -9 deg.C in a cooling tank, and the water 1' is gradually frozen by heat exchanging with the brine. Since the frozen water 1' originally contains the dissolved oxygen to 3 ppm or below, bubble is not almost generated, and hence ice of an opaque portion due to the bubble is prevented as much as possible. Thus, an ice having extremely high transparency and hence high commodity value can be obtained.

CONSTITUTION:After a carrier 32 is fixed, a reactor is exhausted through an exhaustion port 23, and then the reaction gas is introduced through reaction gas introduction ports 21 and the exhaustion is continued. While a constant depressurized state is maintained, plasma is generated by a high-frequency coil 33 and DC electrodes 40, 41, to form a plasma CVD film on the surface of a substrate 31 and to make the introduction gas react on the substrate so that the surface of the substrate 31 is etched. High-frequency voltage and d-c bias one are concurrently impressed to uniformly generate the plasma inside the reactor core tube in this reactor. Besides, a substrate holding part 29 is rotated during the plasma reaction so as to more uniformize the scattering inside the substrate. When the substrate is inserted, a holding part, in which the substrate is placed with its surface turned downward as the flow of gas inside the reaction tube turns downward, is disposed to prevent dust and foreign matters from sticking to the surface of the substrate.

Abstract: PROBLEM TO BE SOLVED: To prevent the flicker of display at the time of starting the display of liquid crystal by changing over the voltage of a piezoelectric transformer driving circuit to the voltage of a voltage generating circuit when an output voltage exceeds a prescribed value with respect to a second voltage signal and to miniaturize a device. SOLUTION: At first, a transistor Q is turned ON and a terminal 1b generating a reference voltage Vr maintains a high voltage and a high output voltage is generated in a piezoelectric transformaer driving circuit 5 at the time of starting a lighting to make a large tube current flow through a cold cathode tube 7 to light the tube 7. The voltage of the terminal 1b maintains a prescribed fixed value for a prescribed period from the starting. In a short time, the base of the transistor Q becomes a voltage higher than the voltage of the emitter side by 1Vf (corresponds to a second voltage) and the transistor Q is turned OFF at the point of time the base becomes lower than the 1Vf. As a result, the voltage of the terminal 1b maintains Vr at the point of time the base is in from the reference voltage Vr till 1Vf and a fixed time later, a preliminarily set low output voltage is generated in the piezoelectric transformer driving circuit 5 to make a small current flow through the tube 7 to maintain the lighting of the tube 7.

Abstract: PROBLEM TO BE SOLVED: To prevent the generation of compost by supplying sludge to a filter tank packed with a filter carrier to filter the same and aerating the filtered-off sludge along with the filter carrier under stirring to microbially decompose org. matter in sludge. SOLUTION: Sludge is supplied to a filter tank in a flocculant added or non-added state to be filtered by the filter carrier 17 charged in the filter tank.
