Patent JP-H0918536-A (JP)
Title: Modulation amplification system
Inventor: MATSUI HITOSHI
IPC: H03F3/68
Filed: 1995-06-28
Abstract: PURPOSE: To amplify an amplitude-modulating signal without distortion by using a power amplifier which has amplitude distortion by converting an inputted digital signal into plural phase-modulating signals, and amplifying and adding the respective output signals together. CONSTITUTION: The 4-bit digital signal inputted from an input terminal 100 is converted by a modulating signal generator 110 into the four phase signals. Respective modulators 120-123 impose phase modulation on the basis of the signals outputted by the modulating signal generator 110. Even when input/ output characteristics of the amplifier 130 are nonlinear, the input signal to the amplifier 130 shifts only in phase and is constant in amplitude, so distortion originating from the nonlinear characteristics never appears. Further, the phase modulation is imposed by the modulators 120-123, so the frequency spectrum of a modulated signal is wider than the frequency spectrum of an input signal, but the phase shift by the modulation is <=±45 deg., so the spread of the spectrum can nearly be ignored and then nearly the same frequency characteristics with linear modulation can be obtained.

Abstract: PURPOSE:To decrease luminous loss, and to uniformalize the brightness of a display surface by forming a resin layer in a reflector by resin for shaping the display surface and resin having excellent transmittance and forming the boundary suface in a curved surface shape. CONSTITUTION:A light-emitting element 11 is connected electrically to a frame 12, and the transmitting resin 14 having excellent light transmittance is solidified spherically and the display surface is formed by the scattering resin 15 having scattering power in the reflector 13. Accordingly, the display surface having excellent uniformity is obtained because the resin is spherical. And luminous loss is decreased because there is the resin 15 between the element 11 and the display surface.

Title: Temperature detecting device for air conditioner
Inventor: SUGIO TAKASHI
IPC: F24F13/20
Filed: 1984-08-01
Abstract: PURPOSE:To accurately detect the ambient temperature regardless of the fan stoppage or operation by disposing the sensing part of a temperature sensor of an air conditioner in the front face of a front grill near a front grill air inlet to project beyond its surrounding. CONSTITUTION:A temperature sensor 4 is attached to the front face 7 of a front grill near an air inlet 6 of an air conditioner, and its sensing part 8 is fixed to project beyond the front face of the front grill around the attachment point. The airflow while the fan of the air conditioner is being operated is primarily directed as shown by arrow 9 to reach a heat exchanger 2. Apart from such, there is a relatively strong airflow that flows as shown by arrow 10 from the outer rim toward the air inlet along the front face of the front grill, and the sensing part of the temperature sensor is located in such an airflow 10. As the attachment point of the sensor is far apart from the heat exchanger 2, it is not affected by the heat exchanger temperature, and since the sensing part 8 is always in contact with the ambient air, the ambient temperature can accurately be detected.

Abstract: PROBLEM TO BE SOLVED: To increase the pulling-out resistance by coating a surface of a nail with the coating, which is obtained by mixing the coating with the adhesive hard grains, and forming projections of the hard grains distributed at random in a surface of a barrel of the nail. SOLUTION: A nail 1 has hard grains 2 of an epoxy resin or the like and a coating film of the acrylic coating 3 or the like in a surface of a head part 5 thereof and a barrel part 4 thereof, which has a sharp tip part 6. The hard grains 2 are strongly fixed to the barrel 4 of the nail by the coating 3, and formed as projections distributed at random over the whole of the barrel part 4. Since the hard grains 2 of the epoxy group resin, which are formed as the projections distributed at random in the barrel part 4 of the nail, is strongly fixed to the barrel part 4 by the acrylic coating 3, peeling of the hard grains 2 from the barrel part 4 is prevented, and the hard grains 2 are inserted with the barrel part 4 into a dividing hole of wood.  With this structure, the projections distributed at random are hooked on the wood fiber, and the hooked part of all the projections generate the pulling-out resistance in relation to the tensile force in the axial direction of the nail 1, and the nail is strongly fixed. As the hard grains, grains having the minimum diameter at 0.1 mm or more is desirable.
