Title: Radio transmitter
Inventor: NAKANISHI MOTOI
IPC: H03B5/32
Filed: 1995-11-21
Abstract: PROBLEM TO BE SOLVED: To enlarge the excitation power of an antenna and to improve intra- oscillation loop efficiency by using the antenna instead of a matching coil of an oscillator. SOLUTION: The coil of a conventional Colpitts oscillation circuit is substituted for the antenna ANT1 and an oscillation circuit 10 is constituted. Thus, power voltage Vcc is impressed and oscillation is started with the amplification function of a transistor Tr and the resonance frequency peculiar to the oscillator Re. Oscillation high frequency current is allowed to flow through ANT1 of the oscillation loop and the ANT1 radiates a radio wave. Since the ANT1 is arranged at the post-stage of the oscillator Re, a harmonic component except for the basic wave of the radio wave which the ANT1 radiates can be suppressed with the filter effect of the oscillator Re. The oscillation power of the oscillation loop is consumed with the radio resistance of ANT1 and the loss of the other oscillation loop circuit element becomes small.

Title: Infrared ray absorption filter and its manufacture
Inventor: ITAYA YOSHINORI
IPC: G02B5/22
Filed: 1990-11-07
Abstract: PURPOSE:To obtain a infrared ray absorption filter which can be formed into a complicated shape and have excellent characteristics by further polymerizing and hardening a synthetic resin composition including an infrared ray absorbing agent. CONSTITUTION:An aluminum system infrared absorbing agent of 0.01-5 weight part is included in a methyl methacrylate single polymer of 100 weight part or a copolymer of 100 weight part composed of methyl methacrylate and acrylic ester, and they are then polymerized under the existence of polymerization initiator of 0.1-10 weight part at about 80 deg.C in a molding block for about three hours to produce a hardened substance having viscosity- average molecular weight of 50,000-7,400,000. Since polymerizing (hardening) temperature is below the decomposition temperature of the used infrared ray absorbing agent, it does not give any bad effect to the performance of the absorbing agent. The hardened substance can be used for an optical filter and noise reduction for compensating the wavelength sensitivity characteristic of an optical element such as a charge coupled device, a photodiode and a light emitting diode.

Title: Drying method for image recording material
Inventor: NAKAMURA HIROSHI
IPC: G03D15/02
Filed: 1986-12-19
Abstract: PURPOSE:To reduce the curl quantity of an image recording material after it is dried by drying the image recording material while it is curled in the opposite direction from the natural curling direction after drying. CONSTITUTION:A heat-developed photosensitive material 16 after transfer is taken out to a disposal tray 38 and disposed of, and an image receiving material 32 is sent to a drying part 40. The drying part 40 conveys the image receiving material 32 by conveyor belts 44 and 46 in a curled state and the material is dried by having one side of the curled convex side (surface opposite from the image surface) heated by a heater 60. The image receiving material 32 after being dried is taken out to a takeout tray 42. The image receiving material 32 immediately after being taken out is slightly curled because it is conveyed in the curled state at the drying part 40, but the material changes into a flat state a fixed time later because of a difference in the amount of moisture between the top and reverse sides (difference in the degree of drying) after the drying at the drying part 40. Consequently, the curl quantity of the image recording material after the drying is reduced.

Filed: 1989-11-22
Abstract: PURPOSE:To obtain the thickness or the thermal physical value of a sample film by intermittently projecting light on the sample film through a light transmitting window, and measuring the generated sound with a microphone. CONSTITUTION:The expression of relation with regard to the thermal physical values, specific gravities and thicknesses of a sample film 5 and a supporting stage 6 and the phase difference between projected light and generated sound are used.

The material of the supporting stage 6 whose changing amount of the phase difference is within the detecting limit is selected. Thereafter, the thickness of the supporting stage 6 is determined. The supporting stage 6 is selected by this method. Then the sample film 5 is attached on the supporting stage 6. Thereafter, the sample film is arranged in a tightly closed container 2. Light is intermittently projected on the sample film 5. The generated sound is measured with a microphone 4, and the phase difference is obtained. Thus the thickness of the sample film 5 is obtained based on the phase difference and the expression of relation.

Abstract: PURPOSE:To relatively reduce peak outputs of a plurality of power sources which outputs currents of square waves in the same period and to obtain the handled output level in high efficiency by combining the output currents of the power sources to output currents of a desired waveform. CONSTITUTION:Currents of variable voltage DC power sources 1, 2 are turned ON, OFF according to square wave signals S1, S2 of a pulse pattern generator Pg by switching transistors Tr1, Tr2 to obtain output currents of desired waveform. When the two transistors are ON together, the output currents are added, while when the one is ON and the other is OFF, currents I1, I2 of square wave are output from the power sources 1, 2 through a diode D1 or D2. Combined output current (I1+I2) of a desired waveform is supplied to a laser discharger through a stabilized resistor Rb. Thus, the currents of a plurality of power sources which output the pulse currents of relatively easily handled square wave in the same period, are combined to supply a current of a desired waveform.
