IPC: C02F3/22
Filed: 1983-07-20
Abstract: PURPOSE:To clean water at low cost, by a method wherein a raw water is permitted to spontaneously flow down through an introducing pipe into which an oxygen-containing gas is blown, and is admitted into an upward flow chamber at a depth position where diffusion of the gas is required for obtaining an air lift effect. CONSTITUTION:The raw water (a) is supplied into an introducing tank 6, is permitted to spontaneously flow down through the introducing pipe 7 under a head between the tank 6 and a head tank 4, and is admitted into the upward flow chamber 2 at a predetermined depth. An oxygen-containing gas is blown through a diffuser port 8 into the raw water (a) flowing down, and is introduced into the chamber 2 together with the downwardly flowing raw water (a). Since the introduction of the oxygen-containing gas is performed at an appropriate depth with respect to the air lift effect, an appropriate air lift effect by the gas is obtained in the tank, and a circulating flow of a liquid is developed. The blowing-in of the gas can be performced at a low depth position in the introducing pipe 7.

IPC: H01L21/68
Filed: 1987-05-29
Abstract: PURPOSE:To correct a sample in a desired flatness by equalizing the potential of a part of a sample holding face composed of a conductive substance to a potential of high or low voltage side to increase an attraction force without necessity of altering an electrode area, a permittivity and an applying voltage. CONSTITUTION:An electrode 3 of high (or low) voltage side and an electrode 4 of low (or high) voltage side are disposed on the same flat face of the top of an electrostatic chuck body 6. An insulatively dielectric layer 2 covering the electrode 3, a conductive material 5 covering the electrode 4, a DC power supply 7 connected between the electrodes 3 and 4, and an insulator 8 having sufficiently low permittivity than an insulator for forming the dielectric layer are provided. With this construction, when a voltage V is applied between the electrodes 3 and 4, the potential of a semiconductor wafer 1 becomes 0V, an attraction force F becomes a function of the voltage V, the thickness (d) and the permittivity epsilon1 of the dielectric layer to generate an attraction force as large as twice. That is, it does not receive a force from a sample holding face equi-potential thereto, but the potential difference which contributes to an electrostatic attraction force by square becomes double as large as a conventional one. Thus, a sample having a large warpage can be held in a preferable flatness state by the large attraction force.

Filed: 1981-08-20
Abstract: PURPOSE:To reduce power consumption, by transmitting the output level of a signal transmitter as the normal value when the transmission information is available and lowering the transmitting level when no call is received after comparing the transmitting signal level with the reference level. CONSTITUTION:The level of transmitting signals given through a terminal (a) is detected by a signal wave detecting circuit 9 and then fed to a comparator 10. The comparator 10 compares the level of the circuit 9 with the reference level given from a reference voltage generating circuit 8. Then a signal transmitter 2 is actuated via a transmission controlling circuit 7 and with the normal RF output level to transmit the signal in case the level of the transmitting signal is higher than the reference voltage. When the level of the transmitting signal is lower than the reference voltage in a non-call mode, etc., the circuit 10 lowers the RF output level of the tranismitter 2 less than the reference level by several to several 10dB through the circuit 7. Thus the consecutive communication is secured to the station of the remote side. In such a way, fine control is carried out to reduce the power consumption of the transmitter 2.

Abstract: PROBLEM TO BE SOLVED: To eliminate the lattice defect on a p-type layer and to easily control the thickness of layer by a method wherein the nitrogen atoms and the III-group atoms, contained in an InGaAlN compound semiconductor, are fed to growth surface alternately, and the atoms which become an acceptor are fed to the growth surface together with the III-group atoms. SOLUTION: When a p-type In1-x (Gay Al1-y )x N layer 4 (0<=x<=1, 0<=y<=1) is formed, III-group atoms 52 and nitrogen atoms 53 are alternately fed to the growth surface. At this point, the feeding of nitrogen atoms 53 is suspended while the III-group atoms 53 and the dopant 51 are bed.

As a result, the dopant 51 does not come in the position between lattices, and the generation of a lattice defect can be prevented.
