Title: Optical disc device
Inventor: NAGASHIMA MICHIYOSHI
IPC: G11B7/12
Filed: 1980-04-23
Abstract: PURPOSE: To enable recording/playback/erasing with high density in real time, by condensing and irradiating an optical beam from a plurality of semiconductor lasers on the optical disc and by controlling the location of the beam group through the separation and detection of one light beam having the shortest wavelength.  
     CONSTITUTION: Each beam from the light source 11 constituting a number of semiconductor lasers as one body is condensed on the optical disc 31 via objective lenses 21, 22. The reflective light from the optical disc 31 is incident to the diffractive lattice 25 via the beam splitter 23 and cylindrical lens 24. Only the playback beam A having the shortest wavlength is incident to the photodetector 26. The recording is made with the light spot a 2  of high power, while tracing the recording bit train (hatched part) with the output of the detector 26 by the spot a 1  of the shortest  wavelength among the light spot trains a 1 Wa 4  on the disc, and the light spots of a 2 W a 4  are sequentially irradiated. Further, recording can be made with the spot (c).  Thus, the recording/playback/erasing can be made with high density in actual time.

Title: Rubber manhole joint
Inventor: TSUDA HIROYUKI
IPC: F16L27/10
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To provide a rubber manhole joint which provides a large degree of freedom in the mounting and construction of a sewerage pipe to a manhole and is not affected by an earthquake and changes of the ground after the construction. SOLUTION: A cylindrical part 1 in which a sewerage pipe is inserted is integrated through a disc like collar part 3 which is provided with a diameter expansion part 2 which is expanded in the radial direction at a terminal of the cylindrical part 1 and is brought into contact with a side wall of a manhole and a bellows part 4 having a cross section in S-shape. The diameter expansion part 2 and the bellows part 4 are on a manhole non-contact face side of the collar part 3 and do not protrude at all on a manhole contact face side of the collar part 3. Even if a necessity that the sewerage pipe is made eccentric after the collar part of a joint is fixed on the side wall of the manhole occurs, the bellows part is elongated and the diameter expansion part is expanded to move the sewerage pipe in the vertical direction.  Moreover, even if changes of the ground occur after the construction and the sewerage pipe becomes eccentric and is inclined, it is possible to prevent the peeling of the collar part and the cylindrical part due to the action of the diameter expansion part and the bellows part.

Title: Burning method for solid material containing impurities at circular flow melting equipment
Inventor: ISHIDA TAKASHI
IPC: F23G7/00
Filed: 1985-03-19
Abstract: PURPOSE:To reduce the amount of generated NOX and dust by burning particles which are shifted within a certain limited size and supplied to a furnace after solid materials containing impurities are crushed by a crusher. CONSTITUTION:Dried sludge in a sewage disposal plant is sent to a crusher 30 through a dried sludge conveyor 3. The crusher 30 is so selected from among various kinds of machines that the machine is capable of crushing the sludge into particles having size under 3,000mum and the ratio of fine particles under 200mum size is made as small as possible. Then, crushed sludge is sent to a sifter 31. Sludge (200-300mum) which is adjusted in grain size to a circular fow melting furnace 9 is injected tangentially into the furnace with preheated air for burning at high velocity. Sludge particles being injected at high velocity are separated from air by centrifugal force and reach a inner wall of the furnace and are captured by melted sludge existing in the place and burnt. At that time, incombustibles contained in sludge particles are melted and flowed down together along the inner wall of the furnace and sent to a smelt desolver 15 with burnt waste gas via a outlet of smelt burning waste gas 14.

Filed: 1980-04-24
Abstract: PURPOSE:To make the ultrasonic solid delayer usable for a high frequency of >=18MHz by sticking two piezoelectric plates to each other and by arranging electrodes on main faces of these plates and arranging polarities of adjacent piezoelectric plates in directions opposite to each other and in parallel with the main face of the delay medium. CONSTITUTION:Two piezoelectric ceramic plates 41 and 42 are used as piezoelectric plates, and they are so stuck to each other that respective polarities are arranged in parallel with the longitudinal direction and in directions opposite to each other as shown in the figure. Electrodes are arranged on stuck surfaces for the purpose of giving the same potentials. Electrodes are arranged on upper and lower faces of plates 41 and 42 to constitute a converter; and if the signal (wavelength lambda) of a prescribed resonance frequency is applied to this converter, plates 41 and 42 are displaced as shown by arrows, and the fundamental wave becomes lambda=2t to form the vibration mode. Consequently, stuck plates 41 and 42 realize the converter of the double thickness in comparison with the conventional converter in the same frequency.

Title: Information processing device
Inventor: OGIWARA MAMORU
IPC: G06F11/30
Filed: 1985-03-22
Abstract: PURPOSE:To connect plural I/O processors having functions reporting a channel fault and an I/O fault by connecting plural I/Os, converting the I/O and reporting the effect to the system. CONSTITUTION:The I/O processors 1-3 are composed of the same I/Os having a common interface with a function reporting I/O and channel faults. When each I/O has a fault, it reports the fault to an information processing device through buses 121-123, and simultaneously sets channel information owned by each I/O to buses 131-133. In such a case, when the information processing device receives the I/O fault from the buses 121-123, it checks that I/O fault is transmitted from which bus. If the I/O fault is reported only from the bus 122, fault information on channels 20-27 is generated through the bus 132, by obtaining the channel constitution of the I/O 2, converted into a channel fault and reported to the system. Thus plural I/Os having the function reporting channel and I/O faults can be connected.

Abstract: PURPOSE:To provide a cold cathode tube lighting device which can positively and entirely light a plurality of cold cathode tubes. CONSTITUTION:Voltage corresponding to entire induction currant flowing in a plurality of cold cathode tubes 11a through 11c is divided by a current detection circuit 14 and a dimming circuit 15 so as to be outputted to a DC/DC converter circuit 12 as control voltage Vcon. The DC/DC converter makes output voltage to an inverter circuit 13 as high as control voltage Vcon becomes low. And the tube current of each cold cathode tube 11a through 11c is detected by a no-lighting detection circuit 16, when it is found that even one cathode tube has not been lighted, and no tube current flows, control voltage Vcon is dropped down to ground potential. By this constitution, the entire cold cathode tubes can be positively lighted at the time of starting lighting, and concurrently the device can be made small in size with cost lowered.
