Title: Separation of iron and very small amount of element
Inventor: OKANO TERUO
IPC: G01N30/88
Filed: 1993-07-28
Abstract: PURPOSE:To separate iron and a very small amount of elements easily with one processing by allowing a liquid solution containing iron and a very small amount to element to positive and negative ion exchange resins and a very small amount of element to be absorbed to at least one of them. CONSTITUTION:A substance containing iron and a very small amount of element to be separated is prepared as aqueous solution of hydrofluoric. It is desirable that the hydrofluoric concentration contained in the aqueous solution should be of a 1-10 normal one. When the aqueous solution is allowed to contact a positive ion exchange resin, iron is not absorbed and transition metals such as Ni and Mn are adsorbed by resin. On the other hand, an element which exists as oxo acid ion of Mo and Sb is adsorbed by a negative ion exchange resin and iron cannot be adsorbed, thus separating iron and a very small amount of element. It is desirable that anion site should be -SO3<-> with polystyrene etc., as a support for the positive ion exchange resin and that cation site should be of quaternary ammonium ion with polystyrene etc., as a support for the negative ion exchange resin.

Title: High-frequency heating device
Inventor: KANEKAWA NORIYUKI
IPC: F24C7/02
Filed: 1998-07-01
Abstract: PROBLEM TO BE SOLVED: To realize a high-frequency heating device that eliminates wasteful power consumption when the device is not used. SOLUTION: The used and unused states of a high-frequency heating device are determined by detecting the opening or closing operation of a door based on a signal of a door opening and closing detection means 26, and when an unused state is determined, a control circuit 18 cuts off the supply of power to the control circuit itself. Thereby, required power consumption can be saved if the control circuit itself continues functioning.  In the meantime, when a weight detection means 24 has detected the weight of food, it is determined that there is a strong possibility that cooking is about to be performed, and the display of the information required for continuing the cooking and the like is prevented from being interrupted by setting a longer standby time, so that the high-frequency heating device can conveniently and safely be used as a cooker without hurrying a user to start the cooking or confusing the user.

Title: Compound semiconductor substrate
Inventor: OKU TOMOKI
IPC: H01L21/285
Filed: 1987-07-24
Abstract: PURPOSE:To secure a treatment speed at a non-contact part where a close contact with a treatment device is insufficient and to prevent a device characteristic from deteriorating by a method wherein a good conductivity layer whose electrical conductivity is larger than that of a compound semiconductor substrate is formed on one side of the substrate, that is to say, on the rear which is to be closely brought into contact with the treatment device. CONSTITUTION:In a GaAs substrate 10 a main substrate 11 composed of GaAs whose electrical conductivity is little and which has a semiinsulating characteristic is provided; in addition, an ion implantation layer as a good conductivity layer 12 whose electrical conductivity is larger than the main substrate 11 is formed on one side of the substrate, that is to say, on the rear which is to be closely contacted with a treatment device during a dry process. For example, <28>Si as impurity ions is implanted into this ion implantation layer at an acceleration energy of about 200 KeV at about 1X10<14> pieces/cm<2>; the layer is formed after this <28>Si has been activated by an annealing operation (a heat treatment operation) at about 800 deg.C. As a result, it is possible to secure the same treatment speed as in a closely contacted part even in a part which is not closely contacted with the compound semiconductor substrate; it is possible to make a treatment uniform and to prevent a device characteristic from deteriorating.

Title: Liquid crystal lens
Inventor: SATO SUSUMU
IPC: G02F1/13
Filed: 1985-08-26
Abstract: PURPOSE:To adjust subtly a focal length with very easy way by changing a bias voltage to adjust the focal length as the reference of a variable focus liquid crystal lens. CONSTITUTION:The high temperature side of the use temperature range in the dependence upon temperature of the focal length of the liquid crystal convex lens is denoted as TH, and the low temperature side is denoted as TL, and the reference temperature is denoted as TO. Since a liquid crystal is melted to become an isotropic liquid at a temperature TI when the temperature of the liquid crystal rises, the temperature TH must be lower than the temperature TI. The bias voltage is applied to bias the value of the focal length to, for example, a value fb of the focal length for the temperature TH. That is, the shortest focal length of the liquid crystal lens is defined as fb. the bias voltage is set to 0 when the temperature of the liquid crystal lens is the highest use temperature TH, and the bias voltage is set to Vb when it is the temperature TO, the bias voltage is made higher than Vb when it is lower than the temperature TO. Thus, the focal length of the liquid crystal lens is always fixed to fb by the output signal of a temperature sensor through the temperature of the liquid crystal lens is changed.
