Filed: 1989-03-14
Abstract: PURPOSE:To deposit hexagonal boron nitride on a substrate by relatively simple equipment by producing a heat plasma of working gas and nitrogen gas by a high-frequency induction method and supplying powdered hexagonal boron nitride into the above plasma. CONSTITUTION:Ar gas in a cylinder 16 is supplied through a feeding hole 10 into a quartz pipe 3 and a high-frequency electric current is allowed to flow through an induction coil 1 by the operation of a high-frequency oscillator 2 to generate an alternating magnetic field in the quartz pipe 3 and ionize the Ar gas, by which heat plasma is produced. Further, N2 is mixed with the Ar gas in a mixing device 11 to produce heat plasma, and the inside of an atmosphere-controlled chamber 6 is evacuated so that the pressure in the chamber 6 becomes lower than atmospheric pressure. Subsequently, Ar gas is fed from a cylinder 17 to a mixing device 14 and powdered hexagonal boron nitride (about 1-10mu grain size) in a damper 13 is fed through a nozzle 12 into the heat plasma to undergo decomposition, by which a film or powder of hexagonal boron nitride is deposited on a substrate 7. By this method, hexagonal boron nitride can be obtained easily and inexpensively.

Title: Water heater utilising solar heat
Inventor: KATOU MASAO
IPC: F24S10/95
Filed: 1984-03-27
Abstract: PURPOSE:To solve the ''blue water'' problem or the adhesion of insoluble blue substance by a method wherein a metal, the ionization tendency of which is larger than that of the metal composing a heat exchange part, and the heat exchange part are connected by means of an electric conductor with spring action. CONSTITUTION:A magnesium ingot 5a employed as an example of a metal, the ionization tendency of which is larger than that of the metal composing a heat exchange part 4, is screw-fixed through an electric conductor 5e to a clamp plate 5c by means of a mounting bolt 5d. Silicone sealing compound or the like is applied in advance onto the contact surface between the magnesium ingot 5a and the clamp plate 5c. Both of the ends of the clamp plate 5c are curved so as to lie along the heat exchange parts 4 respectively, resulting in allowing to have large electrical contact areas between the heat exchange parts 4 and the clamp plate 5c and at the same time to realize the stable mounting structure. Because the metal having the ionization tendency larger than that of copper elutes positively and consequently the elution of copper is suppressed, no ''blue water'' problem occurs.

Title: Waste heat recovering apparatus capable of preventing corrosion by sulfur oxides
Inventor: NAKAMOTO TAKASHI
IPC: F28D15/02
Filed: 1981-04-20
Abstract: PURPOSE:To prevent corrosion by sulfur oxides in a waste heat recovering apparatus,  by keeping the temperature on the surface of heat pipes on their heat absorbing side  always at a level higher than the dew points of sulfur oxides by use of variable conductance heat pipes which are capable of keeping the temperature near the heat absorbing sections of the heat pipes constant irrespective of variation in the temperature of a heat receiving source. CONSTITUTION:When the load of a boiler 41 is lowered, for instance, in the night, the  temperature Tg of waste combustion gas is also lowered. At a heat absorbing section  2, in particular, the temperature drop is great since heat is absorbed therefrom, and  the temperature at the outlet portion of the heat receiving section 2 is lowered near to  the temperature of the dew points of sulfur oxides SOx. In this state, vapor pressure in  heat pipes 3 is lowered, so that the pressure of an incondensable gas G is raised relatively. Resultantly, the theoretical boundary surface BS drops near to the bottom of a  feed water heating section 1 and the effective heat emitting length of the heat pipe 3  is reduced to zero, so that feed water cannot be heated any more in the section 1.  Under such circumstances, however, the temperature of the heat pipes 3 themselves  can be kept at 140 deg.C by the heat of waste combustion gas, so that it is enabled to  avoid condensing of sulfur oxides on the surfaces of the heat pipes 3.

Title: Semiconductor package and manufacture thereof
Inventor: KOSUGE KATSUYA
IPC: H01L21/60
Filed: 1998-03-11
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of defective connection accompanied by the deformation of a mounting board, even when the relay board of a CPS (chip-size package) is constituted of right material. SOLUTION: A stress relaxing groove 10 is provided at the second main surface (the surface on the side facing a mounting board 20) of a relay board 1 comprising rigid material so as to avoid a second conductor pattern 2b and a through bear hole 3. Even when the mounting board 20 is deformed after the mounting of a semiconductor package P1, the relay board 1 can follow this deformation to the certain extent. The breakdown of the connecting part using a solder ball 9 is prevented. When this is applied in the semiconductor package wherein many external connecting terminals are aligned in the area such as in a BGA package and an LGA package, this is especially effective. The stress relaxing groove 10 can be formed by using a cutting device before and after the mounting of the semiconductor chip on the relay board 1 or formed when the relay board is formed integrally.

Then after lapse of a prescribed time, the X, Y, Z displacement quantities of the structure support 1 is measured to decide a stroke correction quantity. Then the cylinders SX1, SX2 of the device on diagonal lines are adjusted to a setting stroke quantity thereby correcting the displacement. Moreover, X, Y coordinates of an auxiliary leg Z are adjusted by step cylinders AJ1, AJ2, the auxiliary leg Z and the cylinders SX1, SX2 are set on a same plane to contract the auxiliary leg Z and the cylinders SX1, SX2 support the structure.

Abstract: PURPOSE:To realize the measurement of a delayed time with high accuracy and easy operation, by measuring the frequency or period of a pulse generating circuit at the time when the input and output pulse signals of a circuit part to be measured are synchronized with each other in phase. CONSTITUTION:The vertical signals supplied from vertical output signal terminals 13 and 14 of an oscilloscope 3 are supplied to an input part of voltage comparators 4 and 5 respectively.

The output signals of the comparators 4 and 5 are equal to the pulse signals obtained by transmitting the signals oscillated from a voltage control oscillator 7 through a pulse generating circuit 2 and correspond to the signal waveforms at points A and B. These pulse signals are compared in phase through a phase comparator 6, and the loss or gain signal is transmitted to a VCO control circuit 8 to control the oscillator 7. The circuit 2 always delivers the pulse signal having a period equal to the delayed time between the points A and B. The signal periods of the circuit 2 are counted at that moment.
