Title: Recovering method for magnetic display medium
Inventor: KONDO TAKAO
IPC: B42D15/10
Filed: 1996-07-08
Abstract: PROBLEM TO BE SOLVED: To enable the recovery of magnetic display media on the dispersion media which exhibit a solid phase state at ordinary temp. and a liquid phase state in heating on bases by heating the display layers of the magnetic display media to the liquid phase state and applying the magnetic on the whole surface and recovering the magnetic display media. SOLUTION: When the magnetic display media 2 are inserted into the insertion port of the recovering device 1, transporting rollers 5 are driven to accumulate the media into a recovering section 6. Heating means 3 in the lateral parts of this recovering section 6 heat the surface layers of the media 2. The whose- surface magnetism applying means 4 in the bottom of the recovering section 6 is operated. When the magnetism is applied on the media, the dispersion media in the magnetic display media are in the liquid phase state and, therefore, the magnetic materials in the display layers of the magnetic display media migrate downward and turn uniform. This state is similar to the initial state. Simultaneously, the erasure of recorded information is possible.  The operation of the whole-surface magnetism applying means 4 may be executed every time the magnetic display media are inserted into the covering device and may be integrally executed after a plurality of sheets of the media are accumulated.

Title: Thermal accumulation method and thermal accumulation device
Inventor: FUJITA TSUTOMU
IPC: F24F5/00
Filed: 1989-07-12
Abstract: PURPOSE:To reduce a dead water region of a heat accumulation tank, improve an efficiency of thermal accumulation and make a uniform thermally accumulated state in each of thermal accumulation tanks by a method wherein the thermal accumulation is carried out at one end of a row of the thermal accumulation tanks, thereafter the thermal accumulation is also carried out again at the other end. CONSTITUTION:At the first stage, if an opening or closing valve V2 is opened to supply cold water from a branch passage 10 to an end terminal tank C7, the cold water is supplied from an intermediate tank C6 to the starting end tank C1 through communication passages l1 to l6. Upon completion of the thermal accumulation, at the intermediate tanks C3 and C5 of the row of thermal tanks C, a relation of a specific weight of each of cold water and returned water and an arrangement state of the communication passages l cause large dead water regions D3 and D5 to be generated. At the second stage, the opening or closing valve V2 is closed and the opening or closing valve V1 is opened and then the cold water is supplied from the supplying passage 3 to the starting end tank C1. At the intermediate tanks 2, C4 and C6, the cold water is supplied from the upper side and flowed out from the lower part. However, each of these tanks does not generate any dead water region due to a difference in specific weights. In addition, the dead water regions D3 and D5 generated at the first state are pushed up and then slight dead water regions D1 to D6 are left at each of the intermediate tanks C1 to C6.

IPC: B25J9/10
Filed: 1986-07-29
Abstract: PURPOSE:To improve mean moving speed, and to shorten a required time, by discriminating the output of an origin switch at every marker position, after detecting a first marker signal. CONSTITUTION:At the time of performing the positioning operation of an industrial robot provided with the origin switch 1 that is an absolute position detecting means, and an incremental system rotary encoder 2 that is a relative position detecting means, a marker signal 21 is searched first by moving a device at low speed. Moving speed is low at this time, but, it is possible to find the signal within one revolution of a detector. After detecting the maker signal, the device is moved in one revolution, that is the next position of the marker signal, then the output of the origin switch is investigated. When no change is detected, the device is moved to the next position. By repeating the above operation, a selected marker signal is set as the reference of a mechanical origin.

Here the water in said both holes 11, 12 is first frozen, and ice in the communication hole 11 is ectruded toward a packing mounting hole 7 by expansion of volume due to a freeze in the chamber 8l. As a result, the packing 9 can be easily removed frm the hole 7 because the spacer 14 and the gland packing 9 are extruded toward an opening of said hole 7.

Inventor: HOSONUMA KUNIHIKO
IPC: G01N21/35
Filed: 1988-07-19
Abstract: PURPOSE:To detect the degree of deterioration of an engine oil corresponding to the deterioration measurement items for the engine oil stipulated in the requirements specified in JIS by optically detecting the quantity of the nitrate contained in the engine oil. CONSTITUTION:The IR light from a light source 2 consisting of a ceramics heater radiating IR light contg. 6.1mum wavelength which is the absorption peak wavelength of the nitrate passes a chopper device 3 and is condensed by a condenser lens 4 so as to enter a sample container 6 in which the engine oil 5 is housed.

This light is then detected by a photodetector 9, by which the photoelectric signal is obtd. This photoelectric output is supplied via an amplifier 10 to a processing circuit 11 which forms the detection signal synchronized with the chopper device 3. The circuit 11 is previously stored with various sets of data for calibration and makes signal processing by using such data, thereby calculating the quantity of the nitrate contained in the engine oil.

Title: Treatment of sludge using petroleum coke powder
Inventor: WATANABE YOSHIHIRO
IPC: C02F11/14
Filed: 1982-10-12
Abstract: PURPOSE:To decrease the amt. of the ash to be generated, by using petroleum coke powder in place of coal powder as an filter aid for hardly filterable sludge. CONSTITUTION:Petroleum coke powder is mixed with sludge and the mixture is filtered. The dehydrated cake obtd. by the filtration is burned as it is or after it is molded to a suitable shape. The heat or gas generated by the combustion is utilized for power generation or the like. If the petroleum coke powder is used as a filter aid for hardly filterable sludge in place of carbon powder, the amt. of the ash to be generated is reduced firstly. Secondly, the treatment is relatively safe although some care is required as the volatile component is small. Thirdly, the colorific value during combustion is larger by about 10-20%, there is the advantage that the satisfactory treatment is accomplished with a small amt. of the powder to be added.

Title: Method and apparatus for recording and reproducing digital audio data
Inventor: FUIRITSUPU SUCHIYUAATO GASUKER
IPC: G11B20/10
Filed: 1984-08-27
Abstract: For both recording and replay, a digital audio tape (14) is accelerated very rapidly by a motor servo (9), motor (8) and capstan (7) so that the tape speed overshoots nominal speed range before settling back to this range in an oscillatory manner. The digital samples are recorded and replayed via a head (15), a random access memory (16) and input/output electronics (19). During recording, the store (17) is precharged by starting to write in as soon as acceleration is initiated. Read-out to the tape is initiated as soon as the tape first reaches the nominal speed range. Uniformity of samples as recorded on the tape is preserved by clocking a read address generator (21) at a rate proportional to tape speed, signaled by a tachometer (7). The write address generator is clocked at the constant sampling rate. For replay the write address generator is clocked at the tape speed rate while the read address generator (21) is clocked at the constant sample rate. Write in and read out are both initiated when the tape speed first reaches the nominal range. The addresses provided by the generators (20 and 21) are compared by a comparator (22) which provides a reference signal to the servo (9) in an arrangement such as to adjust the tape speed always in the sense to maintain a constant degree of filling of the store (17).
