Title: Rotating phase detecting circuit
Inventor: YOSHINO TADASHI
IPC: H04N5/78
Filed: 1978-02-22
Abstract: PURPOSE: To make circuit integration easy by operating an FF circuit with the respective signals  comprising making the rotating phase detection signals to positive and negative alternate pulse  train signals then separating these to the in-phase signals and delaying these signals.   
     CONSTITUTION: The rotating phases of a motor 1 to which a head cylinder 2 is directly coupled  are detected by a head 4 which detects the signals S 1  of alternately different polarities. These  signals are then made to the signals S 2  by an AC amplifier 5 and are then applied to pulse  amplifiers 14, 15 of positive and negative directions, where their peaks are detected. Next, the  addition output signal S 3  thereof is applied to a Schimitt circuit 16 to be made to the signal S 4 ,  which is next inverted in a monostable multi 17 and inversion circuit 18, and is further delayed  at the respective time constants in a monostable multi 19. In this case, the signal S 4   is assumed to be the pulses of duty 50%. These signals are applied to an FF 20 which is set and  reset at the leading edge of the output signals S 8 , S 9  of each monostable multi, whereby the  signal S 10  is obtained. This is compared with the signal from a reference signal generator 11 in  a phase comparator 12 and a motor 1 is controlled by the error signal. Thereby, the circuit  integration is realized with the simple circuits.

Title: Television with pair rental lock function
Inventor: KONUMA MITSUYA
IPC: H04N5/64
Filed: 1995-02-08
Abstract: PURPOSE: To easily cancel or rewrite the identification(ID) numbers of pair rental lock(PL) channels by making it possible to simultaneously cancel the ID numbers of all PL channels. CONSTITUTION: A signal from an external remote controller 8 is sent to an MPU 6 through a signal receiving part 7, and at the time of detecting that PL is applied to a channel selected from a built-in storage part, switches 2, 3 are turned off and no output is sent to display parts 4, 5. In the case of canceling ID numbers, a PL releasing button on the remote controller 8 is depressed, so that the MPU 6 releases all the ID numbers of registered PL channels. In the case of rewriting an ID number, the ID number to be rewritten is inputted and an execution button is depressed, so that the ID numbers of all channels can be simultaneously rewritten. Consequently it is unnecessary to individually cancel or rewrite each channel and all the channels can be simultaneously canceled or rewritten.

Title: Production of coke
Inventor: NAKASAKI AKIKAZU
IPC: C10B57/04
Filed: 1994-02-17
Abstract: PURPOSE:To provide a method for producing high-quality coke having a high strength and density at a low cost without using a raw material coal of good quality. CONSTITUTION:Attention is paid to the reason why the upper part of carbonized cake is poor in quality, especially strength and density of quality difference in the vertical directions thereof from a charged raw material coal layer in a chamber type coke oven is mainly that the bulk density is low in the upper part to freely swell the coal upward in carbonizing the coal and the shrinkage factor is low. Thereby, a raw material coal having a low swelling index measured by the dilatometry and a high fluidity index is blended in the upper part so as to suppress the free swelling of the raw material coal layer in the upper part. Thereby, coal having >=60 total dilatation (TD) and >=2.5 maximum fluidity(MF) is initially charged in the same manner as that of conventional usual charged coal and coal having <60 TD and >=3.0 MF is then charged thereon. The ratio (layer thickness ratio) of the coal layer charged into the upper layer to the total layer thickness is regulated to 0.1-0.3 to carry out the carbonization.

Abstract: PURPOSE:To suppress the generation of high temp. steam and to cool hot coils of high temp. in a short time with small volume of water in the stage of cooling the hot coils in a water tank by submerging the coils in the water tank, covering the water surface with the cooling water ejecting from an ejection port and discharging the hot water under the water surface. CONSTITUTION:Hot coils 11 of high temp. are immersed in a water tank 12 so as to be submerged in cooling water 15 and are cooled with said water. The cooling water is ejected in a slit shape from an ejection port 19 onto the water surface to keep the temp. near the water surface at <=60 deg.C. The foam 13 generated during the cooling of the coils 1 is discharged together with the hot water from a discharge port 16 under the water surface. Since the water surface is kept at <=60 deg.C at all times, the water surface generates no steam that affects working environment adversely or leads to corrosion of structures. The hot water and foam discharged through the port 16 overflows 20 into a storage tank 21 and is cyclically used as the cooling water to be ejected after cooling with a cooler 25; therefore, the hot coils are cooled by the force cooling in a short time with decreased water consumption.
