Title: Method and device for treating waste by utilizing ship
Inventor: TAKAHASHI KATSUAKI
IPC: B09B3/00
Filed: 1989-11-02
Abstract: PURPOSE:To allow recycling by hermetically sealing waste in an oxygen-free state and irradiating the waste with far IR rays at a specified temp., then recovering the effective components. CONSTITUTION:About >=60% water is incorporated in a timber which is discarded. This timber is charged from a feed port 11 into an irradiation chamber 10. Heating gases enclose the bottom and the circumference and the chamber temp. rises to about 150 deg.C when a heating burner 15 is ignited. The radiation from far IR radiating ceramics 13 increases. The sap is evaporated in this way and dissipates to the outside by escaping from the ligneous part. The vapor is passed through a discharge pipe 19 then through a cooling tank by which the vapor is liquefied and is stored as wood vinegar. The ligneous part carbonizes to carbon when the temp. is further increased. The effective components, such as wood vinegar and carbon, are recovered in this way.

Title: A/d or d/a conversion circuit
Inventor: ARAI TAKESHI
IPC: H03M1/66
Filed: 1988-11-14
Abstract: PURPOSE:To prevent the loop-back distortion of a clock signal, by changing the cut-off frequency of an LPF to be arranged at the preceding stage or the following stage of it automatically according to the frequency of the clock signal to be supplied to an A/D or D/A converter. CONSTITUTION:The cut-off frequency of a first LPF 1 is set to be 1/2 of clock frequency f0 from a clock terminal 4. Besides, the cut-off frequency of a second LPF 6 is set to be f0, and is set so that phase difference between its input and its output becomes 90 deg.. Therefore, the clock signals whose phases are 90 deg. different from each other are impressed to a phase comparison circuit 7, and are phase-compared. Compared result is converted into DC voltage by a smoothing circuit 8, and is impressed to the LPF 6. The LPFs 1, 6 are of vari able type, and the cut-off frequency of the LPF 1 is f0/2. When an analog signal is impressed to the LPF 1 from an input terminal 2 in this state, only the signal whose frequency is below f0/2 passes through it, and is A/D converted by the A/D converter 3. Accordingly, a digital signal free from the loop-back distortion can be obtained at an output terminal 9.

Title: Subscriber radio access system
Inventor: ARAI KOJI
IPC: H04L12/28
Filed: 1997-10-20
Abstract: PROBLEM TO BE SOLVED: To perform high throughput communication by correcting an Ethernet packet that uses a carrier sense multiple access(CSMA) protocol to a packet length that corresponds to transmission delay time between terminals of a radio channel. SOLUTION: Packet communication is performed between plural terminal stations 30 to 32 and a base station 2 that is connected to a sensor 1 by a radio channel. Time to go to and return from a transmitting medium here is a time that is counted from the point of the end of a packet which is sent from a sending terminal station until the leading of the packet reaches a sending destination terminal station. Then, the length of the packet is made long, e.g. by adding a dummy packet I to a packet II of a packet length which is defined by a CSMA protocol of Ethernet. With this, it is possible to correctly detect collision even when a radio section is long.

Title: Guidance controller of flying object
Inventor: UEDA KAZUHIRO
IPC: F42B15/01
Filed: 1992-10-26
Abstract: PURPOSE:To obtain a guidance controller for calculating an accurate guidance signal regardless of the characteristics of radome by compensating radome bore sight errors according to antenna angle. CONSTITUTION:Bore sight error characteristics are acquired according to the deviation between the angle signal which is obtained from an angle detector 9 mounted to an antenna 7 and the oscillation angle of a flight table 10. A compensation function is derived from the obtained characteristics by a bore sight error data compensation computer 12, and compensation signal is calculated by the obtained compensation function on operation, thus eliminating error constituents including in the signal which is measured by an error angle detector 2. By subtracting the compensation signal from an error angle, an accurate guidance signal can be obtained regardless of the bore sight error characteristics of radome.
