Title: Treatment of sewage by fluidized bed type apparatus
Inventor: MAEDA NOBUTOSHI
IPC: C02F3/10
Filed: 1982-03-17
Abstract: PURPOSE:To improve the treating performance for sewage in a biological treatment method for sewage by a fluidized bed type apparatus, by using the moldings produced by fixing sludge with a polymer resins a fluid media. CONSTITUTION:Thermosetting resin is added to the cake obtd. by dehydrating the excess sludge produced in treatments of sewage, night soil, etc. and after granulation, the mixture is heated and cured, whereby moldings are obtd. The resins used are phenolic, melamine and urea resins, and are added to the sludge in the form of a precondensate. The resulted spherical sludge moldings have strength and low apparent specific density and float in water usually; therefore, if a prescribed amt. of such moldings are added in an aeration tank, the moldings form a fluidized and suspended state easily. If sewage is supplied continuously into such aeration tank, all the surfaces of the moldings have tachiness on account of aerobic microorganisms, and the treating performance is thus increased.

Title: Communication network control method
Inventor: HASHIMOTO HITOSHI
Filed: 1988-02-26
Abstract: PURPOSE:To automatically discover and connect a normal channel to bypass even when a trouble, line turning-off, etc., occur in a communication network by collecting the information necessary for an information channel connection with respective nodes until it arrives at an incoming call node. CONSTITUTION:For the connection control of a channel for information between an outgoing call node and an incoming call node, a connection requesting packet to request the connection with an incoming call node is made by the outgoing call node side and sent to all adjoining nodes with a channel for a control signal. The node to receive a connecting requesting packet sends a connecting requesting packet to all adjoining nodes again. For the action, the information needed for the information channel connection by a packet is collected by respective nodes until it arrives at the incoming call node and by using the information, the channel for the information is connected. As this result, for the connection request packet, the places of the trouble node and the line turning-off are automatically bypassed and the normal channel is connected.

Inventor: JIYOERU ETSUCHI ROOZENBURATSUT
IPC: F01K25/10
Filed: 1984-03-07
Abstract: An improved engine system is provided which includes a synthetic low temperature sink that is developed in conjunction with an absorbtion-refrigeration subsystem (23) having inputs from an external low-grade heat energy supply (21) and from an external source of cooling fluid (24). A low temperature engine is included which has a high temperature end (22) that is in heat exchange communication with the external heat energy source (21) and a low temperature end (36) in heat exchange communication with the synthetic sink provided by the absorbtion-refrigeration subsystem (23). By this invention, it is possible to vary the sink temperature as desired, including temperatures that are lower than ambient temperatures such as that of the external cooling source. This feature enables the use of an external heat input source that is of a very low grade because an advantageously low heat sink temperature can be selected.

Abstract: PURPOSE:To reduce a noise caused by a frequency dividing circuit of a solid- state image pickup device by setting the number of variations of an output state of a flip-flop to the same number at every rise or fall of a clock. CONSTITUTION:This circuit consists of T flip-flop T11-T14, 2-input AND gates G11-G13, inverters I11-I13, and JK flip-flops JK1-JK3. When a clock is inputted from a T input of the flip-flop of T11, a Q output of T11 is varied from low to high by a first fall of the clock, and simultaneously, the JK flip-flops JK1-3 are varied. By the next fall of the clock, the Q output of T11 is varied from high to low and a Y output of the 2-input AND gate of G11 is also varied from high to low, and the Q output of the T flip-flop of T12 is varied from low to high. Simultaneously, the JK flip-flops JK1, 2 are varied, but as for JK3, even if the clock is inputted, the Q output is not varied. In such a way, a level of a noise also becomes constant and it does not occur that it appears in a video as a fixed pattern noise.

Title: Optical disk
Inventor: SEGAWA HIDEKI
IPC: G11B7/24091
Filed: 1990-02-23
Abstract: PURPOSE:To prevent a pull-in error in tracking and a PLL occurring by setting the shape of a pre-format pit to obtain a synchronizing signal in shape elongated in the radius direction of a disk and the length of the pit at the one longer than surely obtainable the synchronizing signal even at a state where no track ing is performed. CONSTITUTION:Wobbling pits W1, W2 and W'1, W'2 form a pair, respectively, and the gap between the wobbling pits W1 and W'1 is corresponded to the arranging pitch of a track. Clock pits CP1 and CP'1 that are the pre-format pits for synchronizing signal generation are formed in shape elongated in the radius direction of an optical disk, and the length in the radius direction is formed at the length almost equivalent to track width itself. Thereby, a signal having sufficient amplitude can be generated from the clock pit even at a case where the spot of a laser beam passes between the tracks, which surely generates the synchronizing signal. Therefore, an access operation due to a clock defect and an error due to tracking pull-in or PLL pull-in can be prevented from occurring favorably.

Title: Control device for primary delay element
Inventor: ISHII JUN
IPC: G05B11/36
Filed: 1990-02-23
Abstract: PURPOSE:To improve the response controlability and reliability of the control device by means of a simple constitution by providing a gain control means having gain set up to oscillate a control system and a delay means for adjusting oscillation frequency. CONSTITUTION:A digital delay part 4 has delay time DT, a gain control part 5 has gain KT and a voltage saturation part 6 restricts a control voltage VR5 by setting up the maximum voltage of a power supply as a maximum value and outputs and an operation voltage Vs. A controlled part 7 has a primary delay element and outputs a controlled result as a control current Is. When the gain KT of the gain control part 5 is set up to a sufficiently large value and the delay time DT is changed, the oscillation frequency can be adjusted without changing the gain KT. Consequently, the circuit constitution can be simplified. Since a control current is raised by the maximum driving force in a saturation voltage due to the power supply, the controlled part can by quickly and stably driven.

Title: Control of piezoelectric transformer drive frequency in inverter of piezoelectric transformer
Inventor: KISHIMOTO KOHEI
IPC: H02M7/48
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To provide a method for controlling a piezoelectric transformer drive frequency in inverter of a piezoelectric transformer, which can be normally turned on for the whole period from the start-up to steady operation without any intermittent turning-on period. SOLUTION: When a V-F converter 13 outputs a rectangular pulse signal corresponding to the drive frequency of a piezoelectric transformer 15 at start-up, AC voltage is applied between primary-side electrodes of the piezoelectric transformer 15, which then steps up the input drive voltage by a step-up ratio suitable for the drive frequency to apply the step-up voltage to a cold cathode tube 16. The current in the cold cathode tube 16 is converted into a voltage signal proportional to the tube current and then is converted into a DC detected voltage. Thereafter, the detected signal voltage and the tube current setting voltage are compared, and then a differential voltage is amplified to be supplied to the V-F converter 13.  Unlike the start-up time, the V-F converter 13 outputs a rectangular pulse signal having a frequency corresponding to the output from a comparator 19 to a piezoelectric transformer drive circuit 14.
