Title: Hot air generator
Inventor: KOBAYASHI SHIGEO
IPC: F23D11/06
Filed: 1988-01-12
Abstract: PURPOSE:To stabilize the acceleration of fuel vaporization by generating hot air by mixing air flow from the rear part of a burner and burner flames, as well as by forming below a burner a guide surface for gradually upwardly gilding air flows. CONSTITUTION:Burning flames are adapted to enter a duct 44, while external air adapted to be sucked in by means of a suction fan 9 through a net frame 46 portion of a wind shell 7 is also caused to enter the duct 44 after passing the outer periphery of a burner 6 portion so as to be mixed with flames, thereby being transformed into hot air. The flow rate of external air is slightly quickened by narrowing the air passing area near the front end of a burner combustion tube 26, thereby preventing the generation of eddy currents in front of the burner combustion tube 26. An inclined guide surface of a guide unit 38 is provided below the combustion tube 26 so as to allow external air to gradually rise to move, and due to this, even if flames are tried to be diffused when an open condition is abruptly created in front of the combustion tube 26, a vaporization tube 23 is heated by means of flames, especially by means of the lower part of the same since the lower portion is upwardly moved. Hot air generated in the duct portion 44 is allowed to be distributed upstream and downstream of a hot air chamber 8, and it is then discharged out of the device when it reaches an air discharge chamber 11, thus making it possible to dry cereal falling between the relevant portion.

Title: Fluorescent lamp
Inventor: UETSUKI TADAO
IPC: H01J63/08
Filed: 1986-01-14
Abstract: PURPOSE:To enhance the efficiency of light emission, by hermetically enclosing an excited light emission gas and a metal vapor having its ionization voltage near the optimal excitation voltage of the gas, to excite the atoms of the gas in a space between a cathode and an anode to emit light. CONSTITUTION:A cathode 3 and a reticulate anode 4 are disposed in a light- penetrated tube 1 so that the distance between the cathode and the anode is shorter than the mean free path of electrons. The inside surface of the tube 1 is coated with a fluorescent substance. An excited light emission gas of mercury or the like and a vapor of a metal such as cesium, which has its ionization voltage near the optimal excitation voltage of the gas, are hermetically enclosed in the tube 1. A fluorescent lamp is thus constituted. Ionization for generating a low-ionized plasma to neutralize space charge behind the anode 4 is caused by using an ionized gas other than the excited light emission gas. The voltage for the anode 4 is thus lowered to control the electrons to the optimal energy level to heighten the efficiency of light emission.

Abstract: PURPOSE:To increase the surface pressure of contact of flat foil with corrugated foil and to attain satisfactory interfacial joining such as diffusion joining by pressing rolls or sliding plates against a honeycomb body from an outside in radial directions and carrying out winding while producing prestrain in the corrugated foil. CONSTITUTION:When flat foil 2 and corrugated foil 3 obtd. by corrugating flat foil are wound around a shaft to form a honeycomb body 4, winding is carried out while pressing rolls 7 or sliding plates 9 against a formed honeycomb body 4 from the outside. The resulting honeycomb body 4 is heated in a nonoxidizing atmosphere optionally after insertion into an outer tube 5 to join the interior of the honeycomb body 4 or to further join the honeycomb body 4 to the outer tube 5. Inter-facial joining between the flat foil 4 and the corrugated foil 3 of the honeycomb body 4, e.g. diffusion joining is satisfactorily attained and the objective metallic carrier 1 having durability can be produced.

Title: Method for calculating working time
Inventor: KATSURA KENJIRO
IPC: G06Q10/10
Filed: 1992-01-16
Abstract: PURPOSE:To obtain the working time calculating method which can easily calculates the working time without greatly modifying a calculation program based upon a fixed reference working time pattern which is currently used even if a reference working time pattern as a working time pattern varies. CONSTITUTION:Before a variable reference working time pattern which is used separately from the fixed reference working time pattern is generated to calculate a time from time data, the variable reference working time pattern is calculated and registered, and used as a temporary reference working time pattern for the time calculation. Then when the variable reference working time pattern is calculated, not the mere slide calculation of the time of the fixed reference working time pattern, but various logical calculations to which various conditions are added are made. Consequently, the working time calculating method which is made extremely high in efficiency is obtained.

Abstract: PURPOSE: To monitor wear of a tool and obtain good follow-up control of machining by utilizing the phenomena that the sound pressure level of cutting noise is proportional to the load of the tool and that the power with high frequency component increases as the wear progresses.  
     CONSTITUTION: Sound pressure sensed off by an audio sensor 1 is put into a preamplifier 2, where it is estimated in the form of voltage in compliance with sound pressure level.

This ratio VA has a certain relation with the wear of tool tW, whose condition accordingly can have one of the three divisions determined according to the limit wear sound pressure ratio VAL and wear progress sound pressure ratio VAS. Comparators 24, 25 will judge which division the tool concerned shall belong to.

Abstract: PURPOSE:To surely isolate internal constitutional elements from the lubricant in a transmission at all times, by a method wherein a casing is formed of a non-magnetic metal material and a thin-walled ring shaped opening part is formed to the opposed end part opposed to either one of a plurality of magnetic tooth parts of said casing in coaxial relation to a rod shaped core and the detection terminal part of the rod shape core is engaged with the ring shaped opening part through an oil resistant seal part. CONSTITUTION:In such a state that assembling is completed, because the detection terminal part 32a of a rod shaped core 32 is directly opposed to the teeth 22 of a gear, the gap between the detection terminal part 32a and the teeth 22 opposed thereto can be set to a proper value and, as a result, the AC signal from a ring shaped coil 34 can be always secure so as to have output sufficient to detect the rotational speed of an output shaft 12. Even if the detection terminal part 32a of the rod shaped core 32 is exposed to the interior of an output side housing 11, the detection terminal part 32a is inserted in the ring shaped opening part 31a of a casing 31 under pressure through an adhesive 36 and, therefore, the penetration of the lubricant in the output side housing 11 into a cylindrical receiving part 31 is surely blocked always by the synergistic action of the pressure insert state and the adhesive action of an adhesive 36.

Title: Semiconductor device
Inventor: SUZUKI KAZUMI
IPC: H01L29/749
Filed: 1979-01-22
Abstract: PURPOSE:To improve the dv/dt characteristic of a semiconductor device and prevent its gate trigger current from increasing by forming a gate electrode on an insulating film formed on the surface of first base-layer. CONSTITUTION:A gate electrode 8a is formed on an insulating film 6 on the surface of first base layer 2 of pnpn structure having four layers. When the electrode 5 is positive and the electrode 7a is negative, the layers 2, 3 are reversely biased to shut off therebetween. When positive voltage is applied to the electrode 8a and gradually raised, the pn-junction is finally broken down to conduct therebetween. When the positive voltage is further raised, the hFE of a pnp transistor having the layers 1-3 is increased to conduct the SCR. When the electrode 8a is set negative with respect to the electrode 7a and the negative potential is raised gradually, a p- channel occurs in the vicinity of the surface of the n-type layer 2 to conduct with the layers 4, 3, p-channel, and the layer 1. The layers 4 and 1 are connected due the potential of the p-channel to increase the hFE of the pnp transistor having the layers 1-3 and of the npn transistor having the layers 2-4. Thus, the SCR is conducted. Since the SCR is operated with the gate voltage, its trigger current may be very low to improve the characteristic to readily control the SCR.
