Title: Double balanced modulator
Inventor: ORIGASA HIROMI
IPC: H03C1/54
Filed: 1978-03-09
Abstract: PURPOSE: To establish small sized and stable double balanced modulator, by turning ON and OFF the switching element with the carrier e c  and inputting the signal e p  to the non-inverting input terminal of the operational amplifier.  
     CONSTITUTION: When the switching element 2 is OFF, the output e o  of the operational amplifier 1 is e o =e p R 2 /R 1 , since the signal source impedance R g <R 1 . With the element 2 ON, the difference between the non-inverting input and the inverting input is the output to the amplifier 1 and e o =e p . Taking R 1 =R 2 , e o OFF=-e o  ON and the phase is different with the condition of the element 2 by π. When the element 2 is switched with the period T=2π/ω c  of the carrier e c  having angular  velocity ω c , the phase is changed by π at the boundary of switching. Since the  carrier is considered as rectangular waves of ω c  and only the spectrum of the output of the operational amplifier 1 is noticed, the following equation is caused: {Sin (ω p +ω c ) +Sin(ω p -ω c )}+1/3×{Sin(ω p +3ω c )+Sin(ω p -3ω c )+... This shows  the double balanced modulation in progress. With this constitution, the unit is small  in size and stable.

Abstract: PURPOSE:To increase a storage capacity by reflecting a laser beam, which is transmitted through the back surface of an optical disk, by a minute mirror placed on a head and increasing the light intensity of the portion which is limited to the region that is irradiated by the laser beam. CONSTITUTION:A write-in mirror 42 is formed by coating a metallic film, which includes Cr and Al, etc., that have a function of reflecting a laser beam, with an approximate thickness of 1,000Angstrom  on the back surface of an air floating head 11 and a laser beam 8 is made incident on the mirror 42 from the back surface of the optical disk similar to a reading case.

Title: Heat exchanger
Inventor: NAWATA MAKOTO
IPC: F28F13/06
Filed: 1979-03-14
Abstract: PURPOSE: To obtain a high heat exchange efficiency with an improved heat transmissiveness by heating the boiling fluid at a higher temperature than the fluid.  
     CONSTITUTION: Boiling fluid flows in at the lower end lengthwise with respect to the heat transfer plate 15 and fluidizes through a passage formed with the heat transfer plate and a seal plate 4. In the mean time, the fluid flows into a header 11 through a high temperature fluid inlet 13 and undergoes a heat exchange with a high temperature fluid distributed into a hole provided on the heat transfer plate 15. The high temperature fluid is trapped into a header 12 and made to flow out of the equipment. With such an arrangement, the boiling fluid becomes shorter in the unboiling period, which increases the voidity within the boiling fluid passage thereby improving the heat transfer property on the boiling side and ultimately the heat exchange efficiency.

Abstract: PURPOSE: To obtain the poly thin film of GaAs under a high-accuracy control for the film thickness and the chemical quantity composition ratio by means of only one ion source control device and by preserving the advantages of the ion beam crystal growing method.  
     CONSTITUTION: Ga +  ion beam 3 radiated from ion source 1 under control 2 reaches nesa glass 4 to form the Ga thin film on the surface. Ion current 5 of substrate 4 is measured and integrated in a high accuracy through ammeter 6 and integrator 7 and fed back to control unit 2, and then the beam cut-off time of iron gun 1 is determined automatically to attain easily the film thickness deviation of ±0.1%. Then substrate 4 is heated up to a temperature high enough to form the poly GaAs, and then source 10 is switched (9) to control As ion beam 11. The neutral As caused through obtaining the electron from substrate 4 is combined with Ga, and finally full Ga thin film is converted to poly GaAs. With this method, the poly- crystal formation temperature and the conversion time are lower and shorter than those of the molecular line, and the excessive As is evaporated again from the GaAs surface. Thus, the GaAs thin film can be formed with a high accuracy.

Abstract: PURPOSE:To reduce the search time by deciding a comparison program number for searching corresponding to the size of a compared difference between a reproduction program number and an object program number. CONSTITUTION:The object program number set by a keyboard is stored at registers 102 and 104. The content of the register 102 is compared with the reproduction program number stored at a register 101 in a high speed scanning time at a comparator 107, and when a difference value is small, the contact A of a switch 106 is selected. And the reproduction program number from the register 101 is stored as it is at a register 103 as the comparison program number, and by comparing it with the object program number of a register 104, the searching is performed in a rapid response. On the other hand, when the difference value is large, and apart from the object number, a correct program number having no erroneous read decided by the majority of plural program numbers by one time of scanning, etc., through a multiple check circuit 105 is designated as the object of comparison, thereby the search time can be reduced as a whole.
