Title: Axial fan
Inventor: KANEBAYASHI SHINJI
IPC: F04D19/00
Filed: 1988-04-15
Abstract: PURPOSE:To obtain a low-noize axial fan without reducing airflow, by placing a thin cylinder, which has a smaller outer diameter than the inner diameter of a case, between a intake port and a moving blade, and forming a space between the case and the thin cylinder. CONSTITUTION:The outer diameter of a thin cylinder 6 is smaller than the inner diameter of a case 1 and further than the outer diameter of a moving blade 5, and its axial length is shorter than the distance between a intake port 1a and the moving blade 5. As for the outer diameter of the thin cylinder 6, it is desirable that the space between this cylinder and the inner diameter of the case 1 is less than ten times of a clearance g, and therefore a space S1 is formed between the case 1 and the thin cylinder 6. Therefore, flow W2 which is reverse to wind flow W1 in the case 1 flows in the space S1, then being separated from W1 and restricted from colliding to with it.

Title: Method for parallely transmitting light
Inventor: TAKAI ATSUSHI
IPC: H04B10/03
Filed: 1988-04-19
Abstract: PURPOSE:To reduce the scale of a logic circuit by performing encoding for generating error detectable codes from original data at every plural bits and optically transmitting the error detectable codes in parallel with each other, and then, simultaneously performing reproduction of the original data by decoding and erroneous bit position designation. CONSTITUTION:An encoder 1 encodes data by using error detectable codes at every plural bits and optically transmits the encoded data in parallel with the error detectable codes and a decoder 7 decodes the original data and designates erroneous bit positions. Therefore, optical parallel transmission can be realized with a small circuit scale, because optical parallel transmission which can be monitored for fault can be performed and the data rate can be made the same as the transmission rate. Moreover, since the fault processing can be performed easily to the parallel transmission lines when the erroneous bit position designating information is utilized, the reliability of the parallel transmission can be improved.

Abstract: PURPOSE:To provide stable combustion, by constituting an incinerating furnace such that the heating value of an object to be incinerated is computed from an exhaust gas flow rate and temperature, and according to the calorific value, an object to be incinerated and an amount of an air to be fed are decided. CONSTITUTION:Firstly, temperature at the inlet and the outlet of a stabilizer 7 of exhaust gas, and an amount of water dispersed in the stabilizer 7 and the temperature of the fed water are measured. Secondary, based on a temperature measuring devices 11 and 13 and a feed water amount measured by a feed water flow meter 14, an exhaust gas flow rate is computed. Based on an exhaust gas flow rate G, an exhaust gas temperature T1 on the inlet side of the stabilizer, and a feed amount of an object to be incinerated, the calorific value of the object to be incinerated is computed by said computer 16. According to such colorific value H of the object to be incinerated, a feed amount of the object to be incinerated and an air feed amount are determined. In which case, since composition of the object to be incinerated can be estimated from a calorific value, the airfeed amount is computed into an amount which causes excellent combustion of the object to be incinerated.

Cordierite or forsterite is used as first and second insulating layers 3, 4, and the permittivity of cordierite can be diminished largely to conventional alumina, but the thermal conductivity of forsterite is made lower than cordierite. An IC chip 2 is bonded at the central section of one surface of a substrate 1, an electrode 13 made of a Cu plate as a heat-absorbing plate is bonded with the other surface by the direct joining of a metal and ceramics, and a heat dissipation fin 15 made of Al or Cu is joined with an electrode 14 made of the Cu plate as a radiator plate for a thermoelectric transducer 12 through an insulating layer. Accordingly, the resistance of the lead-pattern is lowered, floating capacitance is reduced, and a package having a cooling means for the substrate and high circuit density can be acquired.

Title: Signal voltage level converting circuit and output buffer circuit
Inventor: ORII TOSHIO
IPC: H03K19/003
Filed: 1994-05-09
Abstract: PURPOSE:To provide a circuit constitution which enables every transistor to resists 3V among a gate source, a gate drain and a gate substrate in terms of a semiconductor production process for a signal voltage level converting circuit which converts an input signal of narrow logical amplitude of 0-3V into an output signal of wide logical amplitude of 0-5V. CONSTITUTION:In an intermediate signal generating circuit 2, the voltage applied to the transistors TR Q1 and Q2 is reduced by intervention of the TR Q11 and Q21 in an open mode. Meanwhile the voltage applied to the TR Q3 and Q4 is reduced by intervention of the TR Q31 and Q41 in an open mode. Thus an input signal Vin of 0-3V is once converted into an intermediate signal Vm of about 3-5V. A TR Q71 of an output buffer circuit 3 reduces the voltage applied to a TR Q7, and a TR Q81 reduces the voltage applied to a TR Q8 respectively. Then the signal Vm is converted into an output signal Vout of 0-5V. Thus all transistors can resist 3V or less.

The heat receiving part 22, which receives the radiant heat in such a manner as mentioned above, is made of aluminum die casting, the surface of which is protected with heat resisting paint consisting of ceramics particle, Chrome Black pigment and the like. The protective coating of heat resisting paint prevents the oxydation corrosion of the surface and the overincrease of heat absorptivity due to the increase of surface roughness and blackening, thereby enabling to keep the heat receiving stably over a long period of time by the radiant heat receiving part.
