Title: Automatic frequency control circuit of spread spectrum communication system
Inventor: MIYAKE MASAYASU
IPC: H04B1/7087
Filed: 1986-11-25
Abstract: PURPOSE:To lighten a degree of deterioration due to a frequency shift by taking the product between a sum of reception local signals and a reception signal and making the output of the product into the input signal of an AFC loop through a prescribed band pass filter. CONSTITUTION:An adder 1 generates the envelope line component of the reception local signal, and a multiplier 2 multiplies the signal by an output from a voltage controlled oscillator 8. A multiplier 3 multiplies the output by the reception signal, and the output is passed through a band-pass filter 4, an amplifier 5, a band-pass filter 6 and a frequency discriminater 7. A carrier whose central frequency is the difference or the sum of the central frequency of the reception signal and that of the reception local signal is extracted. The extracted carrier is given as the input signal of the AFC loop to the voltage controlled oscillator 8.

Title: Actuator and peristaltic actuator
Inventor: TAKINAMI MASAO
IPC: B81B3/00
Filed: 1995-10-30
Abstract: PROBLEM TO BE SOLVED: To provide the actuator which is small in size, and can produce high generated force and the great quantity of displacement by supplying thermal energy to an operating element made of a shape memory alloy through self exothermic heat caused by energizing the operating element, and forming the operating element and a spring member into each laminated structure in a thin film shape respectively.

Each Ni-Ti alloy is formed by a spattering method as a thin film 13 for a shape memory alloy so as to be formed into a pattern. In order to form a bias spring 17 as a spring member, a film is formed out of photo-sensitive polyimide by a spin coating method so as to be formed into a pattern by exposing it to ultra-violet rays. An electric wiring 16 and the thin film 13 for a shape memory alloy are so desirable to be formed as in paired ones. By using the thin film 13 for a shape memory alloy as a power source, both high generated force and the great quantity of displacement in comparison with the constitution of the actuator can thereby be obtained simultaneously.

Title: High carbon steel wire rod for extra fine wire having high strength and high ductility
Inventor: FUJITA TOSHIO
IPC: C22C38/18
Filed: 1988-11-09
Abstract: PURPOSE:To provide the title wire rod excellent in mechanical peeling characteristic of secondary scales by providing a specific composition by increasing C and Mn contents and reducing Cr content in a high-C steel in which Si and Cr are combinedly added and which contains Mn. CONSTITUTION:This high-C steel wire rod has a composition consisting of, by weight, 0.7-0.9% C, 0.1-0.6% Si, 0.7-1.5% Mn, 0.1-0.3% Cr, and the balance Fe. Since this wire rod has high strength and high ductility and also has superior mechanical peeling characteristic of secondary scales, an extra fine wire having high strength and high ductility can be manufactured by wiredrawing the above wire rod while reducing evil effects on the service life of a die to minimum. In the above high-C steel wire rod, C is important for the purpose of increasing strength both in the initial stage and after working and the addition of C by the amount of the lower limit or more is necessary to provide high tensile strength, but workability is inhibited when C content exceeds the upper limit. Mn is effective in producing high strength and high ductility, but apprehension of the formation of martensitic structure causing the breaking of wire is brought about when Mn content exceeds the upper limit. Further, C is also effective in providing high strength, but degree of evil effects on scale characteristics is increased when Cr content is increased.
