Title: Scanning type tunnel current arithmetic processor
Inventor: KAJIMURA HIROSHI
IPC: H01L21/66
Filed: 1989-02-09
Abstract: PURPOSE:To speed up analog arithmetic processing by combining a mass-storage device consisting of a scanning type tunnel microscope with an input/output arithmetic means. CONSTITUTION:When information is read out, a driving circuit 14 applies opposite-phase voltages to electrode patterns 113a-113c and 212a and 212b arranged on 1st and 2nd cantilevers 11 and 21 alternately to vibrate the 1st lever 11 in a Y direction and the 2nd lever 21 in an X direction. At this time, the circuit 14 determines respective periods and attains synchronization, thereby scanning recording media 211 on the free end areas 210 of the opposite lever 21 with tunnel current end styli 1111-111n in the free end area 110 of the lever 11. Further, the circuit 14 performs servocontrol over a tunnel current from the center probe of a probe group 111 and applies this voltage to the electrode pattern 113b of the lever 11 to move the lever 11 vertically, thereby holding the distance between the probe group 111 and medium 211 constant. In this state, a mode selecting circuit is put in operation to read information out of the units 2111-211n of the medium 211.

Abstract: PURPOSE:To improve the frequency characteristics over a wide frequency band with a simple constitution in order to be applied to the converter of the speaker, the microphone and the like at the audible frequency region of the telephone, the interphone and the like. CONSTITUTION:The piezoelectric oscillator is formed by adhering piezoelectric ceramic plate 7 to the metal plate, the insulator plate, diaphragm 8 containing the metal foil, etc. Then this oscillator is adhered to disk-type elastic substance 11 made of the elastic substance such as the rubber or the like possessing hole part 15, and then fixed to cylindrical substance 12 in such way that one opening of substance 12 may be closed. At the same time, lead wires 9 and 9' are connected to the areas having conduction to each electrode provided on both surfaces of plate 7, and then external terminals 10 and 10' are connected to terminal plate 13 possessing hole 14. In such constitution, the frequency characteristics of the frequency band is improved owing to the the diameter difference between part 15 of substance 11 and diaphragm 8. Thus the suitable application is ensured to the converter which is used at the audible frequency region of the telephone, the interphone or the like.

Title: Forming method of concave section to surface of resin shape
Inventor: IWATA TAKAO
IPC: B29C51/00
Filed: 1982-02-26
Abstract: PURPOSE:To form the concave section to the surface of the resin shape without generating a projection by forming a concave section, the back thereof is removed, to the surface of the resin shape and pushing and indenting a thick section from the surface side corresponding to the position of formation of the concave section. CONSTITUTION:The concave section E, the back thereof is removed, is formed previously on the back side of the resin shape A. The concave section E, the back thereof is  removed, shapes the escape of the indent of the thick section by a high-frequency welder die B added afterward, and may be formed in volume approximately the same as  or larger than that of a surface concave section C indented and molded in order to  flatten the back side by the indent. The surface corresponding to the position of formation of the concave section E, the back thereof is removed, is treated so as to be  pushed by the high-frequency welder die B to the resin shape A. The thick section F is  indented slowly with the push of the welder die B, and the concave section E, the back  thereof is removed, is buried until the back side is flattened. Accordingly, the concave  section C can be formed excellently because an excessive section does not swell to sections outer than the edge of the concave section C even when the resin shape A is solid  through the formation of the surface concave section C.

Inventor: TAKENAKA FUMIYA
IPC: F24J2/44
Filed: 1982-02-28
Abstract: PURPOSE:To control the room temperature in a simple manner, by constituting a heat collector and a radiator as a single constituent part, and coupling a heat collecting and radiating plate with a heat insulating plate for using it as a blind. CONSTITUTION:During the time the sunlight is avilable, heat collecting and radiating plates 2a are directed toward the sun for absorbing the solar heat, and the heat is transmitted via heat pipes 3. Work fluid in the heat pipes 3 is condensed and transmits heat to a heating medium, i.e., water in a pipe, and the heating medium thus heated causes natural circulation, so that heat is stored in  a tank 5 via a pipe 7. In the night, on the other hand, a pump 10 is set into  operation for circulating the heating medium from the pipe 7 via a condenser- evaporator 4 to a pipe 8 as shown in the drawing, and heat is imparted to the  heat pipes 3 in the condenser-evaporator 4 which functions as an evaporator in  this case. Heat imparted to the heat pipes 3 is radiated into a room A from the  plates 2a which are directed toward the inside of the room, thus heating the  inner space of the room. Here, in order to prevent radiation of heat to the atmosphere, heat insulating plates 2b are directed toward the outside of the  room in the manner that a blind constituted by the plates 2a, 2b is closed.

Abstract: PURPOSE:To improve the vertical resolution of a magnetic field horizontal component to be measured by providing a linear conductor which rotates drawing a column flank and measuring the the voltage across the conductor. CONSTITUTION:A column 2 which has, for example, a 5mm diameter and 10cm length is rotated by a motor 3 at 1,000r.p.m. The induced electromotive voltage induced across the conductor 1, installed on the flank of the column 2, with a magnetic field 10 is hundreds of muV. When the horizontal component of the magnetic field 10 is measured, the induced voltage value in the vertical movement of the conductor 1 is read in a computer 7 from a sample holding device 5 through an A/D converter 6. When the vertical component of the magnetic field 10 is measured, the induced voltage value in the horizontal movement of the conductor 1 is outputted from the sample holding device 5 and processed similarly. The column 2 is moved at various angles to obtain linear integrated values in various directions of respective components of the magnetic field 10 and the computer 7 reconstitutes a distribution of magnetic field components. The instantaneous value of the induced electromotive voltage is measured, so the resolution of the magnetic field is improved to the thickness extent of the conductor 1.
