Title: Composite for thermotherapy
Inventor: KAWAMURA KENICHI
IPC: A61N1/40
Filed: 1987-04-30
Abstract: PURPOSE:To attain effective thermotherapy without generating side effect, by using a composite prepared by bonding a dielectric having dipole moment to a cancerous cell directive substance. CONSTITUTION:A dielectric having dipole moment is a substance inducing dielectric polarization when an electric field is applied and generating heat at the time of dielectric loss and, for example, there is polyethylene glycol. Further, a cancerous cell directive substance is one not bonding a normal cell but selectively bonding only a cancerous cell and, for example, there is the polyclonal antibody to a cancerous surface antigen. A composite is obtained by bonding the dielectric having the above-mentioned dipole moment to the cancerous cell directional substance. For medical treatment, the composite is administered to the affected part at fist. The above-mentioned composite is locally present and accumulated in a cancerous tissue area usually about 30min-2hr after administration and the said area is irradiated with a high frequency wave. By this method, the generation of heat due to dielectric loss is generated and only cancerous tissue is heated. Substratum cancer can be treated selectively and effectively.

Filed: 1983-06-17
Abstract: PURPOSE:To eliminate the use of an auxiliary track and to reduce the circuit in scale by putting an auxiliary digital code signal into the time series space of a main digital code signal which is applied with time base compression, and recording simultaneously both main and auxiliary digital code signals to the same track. CONSTITUTION:The right and left sound signals SL and SR are digitized and written to a pair of RAM4 and 5 via a switching means 3. These written signals are processed for the data arrangement and are written again to the RAM4 and 5. The main digital code signal MDCS which is applied with time base compression is extracted alternately by a switching means 8 since the read clocks of the RAM4 and 5 are earlier than the write clocks. The prescribed arrangement of data is carried out to the signal sent from an auxiliary digital code signal SDCS generator 1 so that said signal can be put into the space of time series of the signal MDCS. Both signals SDCS and MDCS are switched alternately by a switching means 12 and extracted and applied with phase modulation, then recorded to each prescribed track with relative relationship.

Title: Tester for integrated circuit
Inventor: KITA SHIYOUZOU
IPC: H03M1/66
Filed: 1984-05-28
Abstract: PURPOSE:To produce a lower-priced IC tester by a method wherein digital signals equivalent to voltages or currents to be applied to IC terminals are put into a D/A converter belonging to the output circuit of a DC testing unit for D/A conversion into prescribed values to be applied to an IC that is the object of test. CONSTITUTION:In a DC test, memories 16A-16N are fixed at a single address and necessary data for the test are fed out of a sequence controller 7 to this address, and the digital data are consecutively supplied to a DA converter 12. Accordingly, the memories 16A-16N are used as a latch circuit in a DC testing process. A test voltage VH (or a current) is applied to a terminal of an IC3 that is to be subjected to test. The current flowing into the terminal or the voltage present there is determined, for deciding on the acceptability of the IC3. A DC test is accomplished for each of the terminals either by determining the current upon application of a voltage or by determining the voltage upon application of a current. In a functional test, data defining the multivalue logic level to be used in the IC3 to be tested are stored in the memories 16A-16N. By employing this technique, an IC tester capable of using multivalue logic signals may be produced at low cost.

When all of the measured values becomes constant, the pressure of the pressurized air is further increased while watching a pressurized air pressure gauge 12 and the similar measurement is effected. A status wherein the muddy water A is infiltrating is graphed and a coefficient of mud lessening is obtained by catching a point of intersection of a curve of the infiltrating amount, which decreases gradually, and a standard value of the muddy water infiltration. A muddy water shield digging work is effected based on the obtained coefficient.
