Title: Solar light condensing device, condensing diffusing device and automatic solar light following sensor used therefor
Inventor: MOTODA KENRO
IPC: F24S50/20
Filed: 1992-04-08
Abstract: PURPOSE:To utilize solar light instead of an artificial light source and to obtain the extremely drastically saving effect of energy by condensing the solar light by automatically following the movement of the sun and supplying it to an aimed place. CONSTITUTION:The turning mechanism 10 of a fitting table 7 provided on the base part 7a of the table 7 is formed so that a pedestal 10b can be turned around a vertical axis Va by receiving the rotational output of a motor 10a by a gear array, a belt power transmission mechanism or the like. Thus, first and second concave mirrors 1 and 2 being the condensing factors of the solar light can execute a turning action around the axis Va in addition to an oscillating action in a vertical-plane. That means, since the light condensing factors can be turned by 90 deg.-180 deg. in the vertical-plane and turned around the axis Va by 360 deg. with respect to the surface of a ground, they can be always faced to the sun at an installing position from sunrise to sunset. In such a case, a solar light following sensor is used and respective driving motors 9 and 10a are controlled based on the output of the sensor.

IPC: H01L21/28
Filed: 1979-09-06
Abstract: PURPOSE:To prevent the breaking at a stepped section on a conductor layer and to accomplish manufacture of the semiconductor device having an improved degree of integration by a method wherein the stepped section is provided on a field oxide film. CONSTITUTION:A source and drain region 12 is formed by diffusing phosphorus on a P type silicon substrate 11. Then a thick oxide film 13 is formed by performing a heat oxidation or using a CVD method. Next, phosphorus is injected from the surface of the oxide film 13 using an ion injection method and an impurity doped layer 13A is formed. Subsequently, the area excluding the gate region is covered by a resist 14 using a photolithographic technique. Then a dryetching is performed on the oxide film on the gate region of the oxide film 13. At this time, as etching rates vary according to the ion injected impurity, the difference in level at the stepped section is making a gentle slope. As a result, occurrence of a breaking at the stepped section when a conduction layer 16 is formed after formation of a gate oxide film, can be reduced.

When the endoscope catheter is used and inserted to a branching vessel 1, the guide wire 32 is retreated by pulling the forceps 39 in this side and the tip of the catheter 30 is restored to an original shape. Then, since the catheter 30 is bent upward, the catheter can be inserted into the objective blood vessel into the branching vessel 1 in this case without damaging the wall of the blood vessel. Then, since the guide wire 32 is slided forward/backward and the bending degree and direction of the tip are changed, the observation can be executed over the wide range.

Title: Charging resistor protective circuit
Inventor: OHORI MASARU
IPC: H02H7/122
Filed: 1993-04-19
Abstract: PURPOSE:To realize downsizing and cost reduction of the circuit by providing a filter circuit simulating the charging time constant and a comparator comparing the power supply voltage passed through the filter circuit with the voltage of a filter capacitor thereby allowing employment of an initial charging resistor for filter capacitor having rated power. CONSTITUTION:When an input switch 1 is closed at the time of starting a power converter 6, a filter capacitor 5 is charged through a charging resistor 4 at a time constant RC and the voltage Vc of the capacitor 5 increases. Since a filter circuit 11 also has a charging time constant RC, the voltage Vc of the filter capacitor 5 drops when the power converter 6 or the filter capacitor 5 is short-circuited due to abnormality. Consequently, an abnormality detection signal is delivered from a comparator 8 and the input switch 1 is opened thus protecting the charging resistor 4 against burning. Since the short circuit current does not flow continuously through the charging resistor, downsizing and cost reduction can be realized for the circuit or the unit.

Filed: 1996-04-12
Abstract: PROBLEM TO BE SOLVED: To provide a light-weight leg retracting mechanism of leg brace which allows a patient with legs paralyzed to extend/retract shoes soles using his/her remaining ability to make him walk freely. SOLUTION: At an auxiliary shoe sole, a mechanism (leg retracting mechanism) which changes the sole thickness by the manual rotation of a handle grip 21 is provided.

IPC: H01L21/338
Filed: 1977-09-27
Abstract: PURPOSE: To make non-doped layers of a constant low carrier concentration at the time of repeatedly growing undoped low carrier concentration layers and doped high concentration layers with the same Ga source by heating the Ga source in high purity H 2  before the growth of the impurity undoped layers.  
     CONSTITUTION: A specified temperature distribution is formed by putting Ga 3 in a boat 2 in N 2  gas. When the Ga source is at 850°C, the inside of a reaction tube 1 is substituted with high purity H 2  and H 2  is flowed at 1l per minute to perform treatment for about 2 hours thereby removing the impurities of the Ga source. After H 2  is stopped, AsCl 5  5 is introduced with N 2  as a carrier. After As is saturated in the Ga source, a buffer layer undoped with any impurity is grown on a Gas substrate 7. Next, impurity doped gas is flowed into the tube to allow an active layer of a high concentration to grow to a specified thickness. The substrate 7 is withdrawn after cooling. As a result of these repetitions, the carrier concentrations of the respective undoped layers become of a constant low concentration
