Title: Feedback circuit for integrated circuit
Inventor: FUKUCHI SATOSHI
IPC: H03F1/08
Filed: 1980-02-18
Abstract: PURPOSE: To realize a process of a capacitor within an IC, by securing a small capacity by using a Miller integral network for the feedback capacitor.  
     CONSTITUTION: A differential amplifier consisting of the transistors (TR)Q 5  and Q 6  is used for a Miller integral network, and the emitter of TRQ 4  is connected to the base of TRQ 5  which is opposite to the base of TRQ 6  that performs a Miller integration. At the same time, the base input terminal of TRQ 4  is connected to the emitter terminal of TRQ 2  of the feedback input terminal. The signal leaks into the base of TRQ 5  at a low frequency less than the cut-off frequency of the LPF consisting of the base input capacity and the input resistance R at the base side of TRQ 4 . In the same way, the signal is supplied to the base of TRQ 6  at a frequency lower than the cut-off frequency of the LPF type feedback circuit consisting of the resistances Rf and Ri plus the equivalent capacity Ci. This signal has the same phase as the signal of the base terminal of TRQ 5 , and thus the differential amplifier comprising TRs Q 5  and Q 6  has no saturation. In such constitution, the value of the capacity Ci can be reduced greatly.

Title: Utilizing device for solar radiant heat
Inventor: UEMATSU JIYUNJI
IPC: F24S23/00
Filed: 1980-02-20
Abstract: PURPOSE:To decrease heat loss due to radiation from heat receiving bodies, increase the heat absorbing efficiency of solar radiant heat and elevate a temperature in a shape more effective for the utilization of heat by forming prismatic projections on an inner surface of a transmitting body covering an outer box, the inside thereof has the heat receiving plates. CONSTITUTION:Prismatic projections are made up on an inner surface of a transmitting body 3 covering an outer box 2, the inside thereof has heat receiving bodies 1. All radiant heat from the sun pass through the transmitting body 3 and enter to the inside by making up the crests of the projections in the east and west direction, but the half of radiant heat projecting to the transmitting body 3 from the inside is returned to the inside again because the principle of a prism is that rays projecting to one surface are projected from the other surface, thus increasing the heat absorbing efficiency of solar radiant heat. Reflector plates 4 are mounted at the south and north both ends of the transmitting body 3, and the half of radiation projected to the outside is returned to the inside through the transmitting body 3 again. As a result, the heat absorbing efficiency of the solar radiant heat is further heightened.

Abstract: PURPOSE:To increase the margin of back reading and stabilize the reading by discriminating front printing and the back reading in accordance with the sequence of an read output of a character such as date and a reading output of a mark such as a hyphene or comma. CONSTITUTION:Digital signals 8a, 8b outputted from a reading gate circuit are sent with a prescribed sequence by shifting the printing position of a mark such as a hyphene or comma from the printing center of the a character. When the mark signal 8b is outputted to the upper half of the output area of the character signal 8a, it can be decided that the output is the printing line 2a of the  back page, and when outputted to the lower half, the output is decided as the output of a printing line 2. Consequently the printing line 2 of the front page  can be distinshed from the printing line 1 of the back page regarding the character reading signal 8a by timing sequence generated by the mark reading signal  8b.

Filed: 1982-02-10
Abstract: PURPOSE:To hold the air-to-fuel ratio at a proper rate by installing a counterflow preventive member in a by-pass air passage and by preventing malfunction of the airflow meter owing to counterflow. CONSTITUTION:The upper flow of a venturi part 4 and the narrowest part of the same 4 are in communication through a by-pass air passage 5, and a heat radiation flowmeter 6 is installed on its midway. The output of this flowmeter 6 operates a proportional solenoid valve 23 with the aid of a computer 9 so that the rate of air flow will become constant. Pulsation and counterflow of the intake air stream generated when the engine is full open for low speed operation permits the flowmeter 6 to output a signal as a large rate of air flow and, thus, a rich mixture gas is supplied to the engine, and therefore a cylindrical convolution chamber 30 is provided in order to prevent it. Accordingly a counterflow flows in the convolution chamber 30 in its tangential direction, so that a large fluid resistance is produced to hinder generation of counterflow in the by-pass air passage 5.
