Title: Hot air heater
Inventor: ISHIKAWA YOSHIJI
IPC: F24H3/04
Filed: 1988-01-27
Abstract: PURPOSE:To protect a filter against an over-heated air by a method wherein an air passage for passing air heated by a heating source out of a casing without passing through the filter when a blower is stopped is arranged near a suction port of the casing. CONSTITUTION:A filter 11 is provided with at its upper central part a heat- resistant protective member 11a and forms an air passage through which the heater air within the casing 10a is passed together with an enlarged part 12b. In case of a gas fan heater 1, during its operation, a convection flow fan 13 is stopped, an interior air is not sucked from a suction port 12, resulting in that the heated air within an inverse casing 10a ascends through draft, accumulated at the upper part within the casing 10a, the upper part of the casing 10a is filled with hot air and gradually the air is accumulated at the lower part of the casing 10a. At this time, the hot air filled in the casing 10a is flowed out of the enlarged part 12b acting as an upper opening, so that the heated air may heat only a protective member 11a and may not reach the filter 11, and so the filter 11 can be protected.

IPC: H01L21/331
Filed: 1982-02-04
Abstract: PURPOSE:To obtain an IC which can be readily controlled in an hFE by forming a stepwise difference on the surface of a base region by utilizing a thermally oxidized film and diffusing an emitter. CONSTITUTION:Two N<+> type layers are buried in space in a P type Si substrate 11, an N<-> type epitaxial layer is superposed, isolated with a P<+> type layer, and a P type base layer 16 having approx. 3mum of depth is simultaneously formed in the obtained island 15. When holes are selectively opened at an oxidized film 17 and a thermally oxidized film 18 having the prescribed thickness is formed, a film 18 is grown with the layer 16 recessed, and a stepwise difference is selectively formed on the surface. When holes are then opened on the layer 16 and an N<+> type emitter layer 19 having 2mum of depth is formed, the widths of the base regions are different depending upon the stepwise difference of the oxidized film on the surface, thereby forming different hFE. According to this configuration, since the hFE can be arbitrarily selected in accordance with the thickness of the thermally oxidized film on the surface of the base layer, the thickness of the film can also be readily controlled in an accuracy of + or -0.1mum and treated in a furnace, a mass production can be performed.

Title: Protective circuit for overcurrent of switching regulator
Inventor: HARA SHINICHI
IPC: H02M3/28
Filed: 1986-01-31
Abstract: PURPOSE:To control currents accurately in magnitude at a predetermined level by preventing overcurrents by the supply relationship of a first overcurrent detecting circuit and a second overcurrent detecting circuit. CONSTITUTION:When the state of a short circuit is generated, currents flowing through a transistor 4 gradually increase, and reach to the set value of a first overcurrent detecting circuit 20. Voltage corresponding to the currents is applied to an inversion input terminal for a comparison amplifier 23, but the comparator 23 does not generate an output instantaneously. When currents further increase and reach to the set value of a second overcurrent detecting circuit 21, a transistor 27 is turned ON instantaneously, and the collector voltage of the transistor 27 is brought to a low level. A control signal receiving an overcurrent detecting signal represented by the collector voltage transmits a drive signal having narrow pulse width over the transistor 4, and ON time of the transistor 4 is shortened. The comparison amplifier 23 generates an output in a control circuit 11, and the first overcurrent detecting circuit 20 suppresses the overcurrents to a set value.

Title: Production of zinc-based plated aluminum plate excellent in zinc phosphate treating property
Inventor: YAMANAKA YOICHIRO
IPC: C23C18/48
Filed: 1994-02-15
Abstract: PURPOSE:To produce an aluminum plate excellent in zinc phosphate treating property at low cost. CONSTITUTION:A zinc base plating bath containing 0.1-3.0g/l free fluorine and adjusted to pH3-1.5 is brought into contact with the aluminum plate at >=0.5m/sec relative flow rate, and subjected to displacement plating. Metal components incorporated in the plating bath are Zn and Ni, Mn, Fe or Co less than zinc content, and may be contained with metal of 10-100g/l as total amount. By keeping the relative flow rate, the removing of a remaining oxidize film on the aluminum plate is accelerated, and the dissolving of Al is appropriately balanced with the replenishment of a displaced metal to a displacement point to obtain a dense and uniform plated film in short time. A chemical conversion film excellent in covering property is obtained at the time of zinc phosphate treating.

Title: Controlling method for air conditioner
Inventor: SUGIYAMA AKIYOSHI
IPC: F24F11/02
Filed: 1988-01-28
Abstract: PURPOSE:To eliminate an improper controlling operation due to an erroneous judgment as soon as possible by a method wherein a discrimination for the type of outdoor machines is effected when a power supply is turned on and at least one time judgment for the type of outdoor machines is carried out until the operation of the outdoor machines is stopped. CONSTITUTION:When a power supply is turned on at a time(t1), a controlling part 4 may transmit a machine type discriminating signal, a controlling part 5 may transmit back a machine type signal to discriminate an outdoor machine type. When an operating instruction is given from a remote control device 6 at the time t2, the controlling part 4 may start an operation of the indoor machine 1, the control part 5 may start an operation of the outdoor machine 2. As the control part 4 may transmit an operation control instruction S21, the controlling part 5 may transmit back the operating condition signal. As the stopping instruction is given from the remote controlling device 6 at the time t3, the controlling part 4 may output a machine type discriminating signal and the controlling part 5 may transmit back the machine type signal to perform a discrimination of the outdoor machine type. The controlling part 4 may terminate the indoor machine 1 and the controlling part 5 may terminate the outdoor machine 2. In this way, when a termination instruction is received, the discrimination of the outdoor machine type is carried out and even if the power supply shows a sagging and the type of outdoor machine is erroneously discriminated due to noise, an improper controlling operation is eliminated during a restarting operation.

Further, the ends of plastic clad quartz optical fibers 6, from which the coatings at the front ends are removed and which are cut at the front ends of the cores/clads to form specular surfaces, are inserted into fiber insertion holes (total 8 points). After the fibers 6 are tentatively fixed by means of jigs, the block body is irradiated with UV rays, by which the core resin is cured to polymerize. The 4:4 optical branching appliance of a fiber pigtail type is thus obtd.
