Title: Solar heat hot air device
Inventor: WATANABE SEIICHIROU
IPC: F24J2/04
Filed: 1980-04-25
Abstract: PURPOSE: To decrease the heat loss due to heat radiation in a solar heat hot air device by employing the heat absorbing surface with uneven surface such as a metallic mesh or the like so that a boundary layer for disturbing the internal air stream may not be developed.  
     CONSTITUTION: A solar heat transmitting plate 1 is engaged with a box 2 formed of heat insulating material, an atmospheric air intake port 3 is provided at the bottom, a hot air exhaust port 4 is provided at the top, and a heat absorbing member 5 with uneven surface such as, for example, a metallic mesh, a porous plate, a file or the like is supported in one or more layers in parallel with the plate 1 in the box 2. When the temperature of the heat absorbing member 5 is raised and there exists a temperature difference from the peripheral air, the air is heated by the heat transfer. Since the air stream is constantly disturbed by the uneven surface of the heat absorbing member 5 in this case, a boundary layer 1 is not developed. Since the heat transmission rate is not thus decreased, it can suppress the heat loss due to the heat radiation.

Abstract: PURPOSE:To evade contamination due to dust and dirt and prevent the formation of foams due to the contamination by charging numbers of glass fibers for picture element lines in a glass pipe and then irradiating them with ultraviolet rays while supply gas containing oxygen, etc., into the pipe, and heating and drawing the pipe. CONSTITUTION:Numbers of glass fibers (GF) constituting picture element lines are charged in the glass pipe and then while gas containing O2 or O3 is supplied into the glass pipe, the fibers are irradiated with ultraviolet rays. Then, the GFs and glass pipe are heated into one body and drawn thermally. Thus, the fibers are irradiated with ultraviolet rays while O2 or O3 is flowed into the GF bundle in the glass pipe to oxidize and dissolve away organic dust which causes the formation of forms, e.g. human skin and sweat, dirt, oil, solvent, smoke, fiber, etc., suspended in air. Ultraviolet rays with short wavelength are used preferably for the oxidation. The obtained image fiber contains no air foam among picture element lines, so an image of good quality is transmitted.

Title: Signal detecting circuit
Inventor: HAYASHI HIDEAKI
IPC: G11B20/14
Filed: 1982-04-07
Abstract: PURPOSE:To shape a waveform accurately, by comparing the width of a compared pulse with a prescribed width and controlling the reference voltage of a comparator so that the difference between them is always zero. CONSTITUTION:Latch data of a latch circuit 5 is subjected to D/A conversion to obtain a DC output. This output is given to a comparator 7 and is compared with a reference voltage E2 set to a voltage corresponding to a prescribed phase, and the error output is obtained. If the pulse width of a reproduced waveform is wider than a prescribed width, a positive voltage is added to the voltage of a reference voltage source E1, and therefore, the voltage of a comparator 1 rises, and the pulse width on the plus side of the output of the comparator 1 becomes wider. Since this operation is always performed, the output pulse has a correct duty. Even if there are asymmetrical components in the level of the input reproduced signal, an optimum pulse shaping is always performed.

IPC: F24D5/10
Filed: 1987-03-13
Abstract: PURPOSE:To eliminate such inconvenience as unnecessary overheating of a heat exchanger by driving a blower placed in a hot air passage in response to the heat demand of a load. CONSTITUTION:To a space heating apparatus 3, a heat exchanger 2 circulating forcibly heat medium between an outer load 1 and itself is attached. This exchanger 2 is arranged inside a hot air passage 4 and a blower 5 is placed in the passage 4 and hot air is supplied into the passage 4 by the blower 5. When heat demand is required by the load 1, the heat medium is forcibly circulated between the load 1 and the exchanger 2 and hot air is forcibly supplied by the blower 5. Therefore, necessary heat for the load 1 is able to be supplied. When heat demand by the load 1 is stopped, the blower 5 is stopped in response to this condition. Thereby, hot air supply to the passage 4 is stopped and unnecessary heat exchanging of the exchanger 2 is stopped to prevent its abnormal overheating.

Title: Opening and closing damping device for article storing box in compartment
Inventor: OSHIDA TSUTOMU
IPC: E05F3/02
Filed: 1987-03-13
Abstract: PURPOSE:To prevent dust in a compartment from entering a piston, by providing a dust isolating device in a cylinder type air damper and mutually communicating the air sealed in both spaces in a cylinder. CONSTITUTION:A check valve 8 is adapted to abut against a piston 5 from a rod chamber b side to close a communication hole 9. In an expansion stroke for drawing a rod 6 out of a cylinder 4, a head chamber a is reduced in pressure, and the rod chamber b is increased in pressure. As a result, the check valve 8 is closed to allow the communication between both the chambers a and b only through an orifice 7. Accordingly, the air in the rod chamber b flows through the orifice 7 to the head chamber a. Thus, a braking force is generated in the expansion stroke of the rod 6. Therefore, when an opening operation of a storing box is interlocked with the expansion stroke of the rod 6, the braking force is applied only upon opening of the storing box by utilizing only the air in the cylinder 4 without inducing the outside air into the cylinder 4. As a result, the storing box is slowly opened by its tare and an internal weight as an energizing force for opening.
