Title: Vibration damping equipment
Inventor: FUNAKI TAKASHI
IPC: F16F15/03
Filed: 1984-11-13
Abstract: PURPOSE:To make a vibration damping ratio improvable, by altering a magnetic field of an electromagnet body with a variation in current carrying capacity, while controlling a variation in apparent viscosity of a magnetic fluid. CONSTITUTION:With an electromagnet part 11, a magnetic field is avoided becoming extremely unbalanced, and a very effective magnetic field 14 is addable to a magnetic fluid 4 flowing in a narrow passage part 3 formed between an inner circumferential surface of an outer tube part 1 and an outer circumferential surface of an inner tube part 2. Therefore, apparent viscosity in the magnetic fluid is yet more increasable owing to the magnetic field 14. And, the said apparent viscosity in the magnetic fluid 4 regulates current carrying capacity of the electromagnet part 11 from the outside, making it controllable, thus a vibration damping ratio is made so favorable enough.

Title: Method of carrying bulk material, and structure of lowering friction of bottom surface of bulk material
Inventor: NAITO MASAMITSU
IPC: B65G7/06
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To easily carry a bulk material on a support by providing a fluid filled space between the bottom surface of the bulk material and the floor surface of a carrying path, and fitting the fluid pressure at a degree capable of preventing the separation of the bottom surface of the material to be carried from the support provided on the floor surface of the carrying path so as to lower the friction between the bottom surface of the bulk material and the support. SOLUTION: In the case of carrying a bulk material 110, a pump 140 is operated so as to fill the water 150 inside of a seal member 130, and the seal member 130 is expanded so as to tightly contact with a bottom surface 111 of the bulk material 110. The water 150 inside of the seal member 130 is injected into a water supply space 120 formed inside of the annular seal member 130 through an opening 131 so as to fill the water supply space 120 with the water 150 for pressurization. In this condition, [water supplying pressure]×[an area surrounded by the seal 130] partially supports a load of the material 110 to be carried, and the weight to be applied to the support 101 is reduced by that load supported by the [water supplying pressure]×[an area surrounded by the seal 130] from the weight of the whole.  Namely, since the friction between the support 101 and the bottom surface of the bulk material 110 is lowered, the bulk material 110 can be hauled by a relatively small hauling force.

Title: Writing pressure control apparatus of plotter head
Inventor: ICHIKAWA MASAMITSU
IPC: B43L13/00
Filed: 1990-09-07
Abstract: PURPOSE:To control writing pressure in conformity with an actually measured value and to always obtain good drawing quality without being affected by the irregularity or secular change of an apparatus by estimating actual writing pressure on the basis of shock quantity at the time of the down of a pen. CONSTITUTION:A controller 33 outputs the writing pressure control signal corresponding to the kind of the pen 10 set at the present time to a writing pressure control circuit 34 which in turn forms a PWM signal of necessary pulse width to drive a moving coil 36 through a driver 35. By this mechanism, a pen 10 falls. Since the point of the pen 10 collides with a buffer member 23 through a protective sheet 24, an output signal is obtained from a condenser microphone 27 to be amplified by an amplifier 31 and converted to a digital signal from an analogue signal by an A/D converter 32 to be taken in the controller 33 as data showing shock quantity. The controller 33 estimates actual writing pressure from the output value of the condenser microphone 27 and the relation between the shock value and writing pressure stored in a memory 37 to control the same until it becomes a predetermined expected value.

Title: Gradation recording device
Inventor: TANAKA HIDEYO
IPC: H04N1/04
Filed: 1986-10-08
Abstract: PURPOSE:To attain a uniform, sharp gradation recording with a simple constitution by dividing one picture element into plural parts in the feed direction of a recording paper based on gradation instruction information transmitted from a recording controller controlling recording, varying the are of the one picture element and carrying out the gradation recording. CONSTITUTION:The terminal recording paper 13 is made of a base paper 12 and a coloring layer 11. A thermal head heating element 10 consists of plural heating elements with width of one picture element, and said element 10 has one third of said width in the moving direction of the recording paper. Since plural thermal head heating elements 10 are provided for one dot line, they are selectively conducted based on recorded data to form a dot pattern. When the thermal head heating element 10 is conducted, the temperature of a thermal head rises. When said temperature exceeds the coloring temperature of the coloring layer 11 composing the recording sheet 13, the element 10 colors in a regulated color. If the temperature rises further, the coloring density is constant. Time required for feeding one picture element in the recording paper 13 is divided into three portions. The width of a conductive pulse for the thermal head is set so that the thermal head heating element 10 is heated beyond the temperature of the coloring layer 11.

Filed: 1994-09-30
Abstract: PURPOSE:To reduce an occupancy area and to reduce a cost by realizing a function equivalent to the function which was realized by plural pieces of serial access memories by connecting two transferring registers in series. CONSTITUTION:The registers 117, 127 for read are connected in series.

Thus, the data read out from a memory cell array 101 are transferred to the register 127 through the register 117. On the other hand, when the data are inputted to the register 117, the circuit 115 is turned ON in response to the PRT1, and the circuit 127 is turned OFF in response to the PRT2, and the data read out from the array 101 are transferred to the register 117. By such a constitution, the memory with a low cost is obtained.

Abstract: PURPOSE:To improve the wire bonding property of an electronic circuit by performing a cream solder printing process, mounting process, reflow process, washing process, hydrogen plasma treatment process, wire bonding process, and sealing process in this order. CONSTITUTION:After a glass epoxy substrate having wire bonding pads respectively composed of three layers of Cu foil, an Ni layer, and an Au layer is printed with cream solder in a cream solder printing process, chip parts are mounted on the substrate with a mounter. After a reflow process is performed on the substrate by using a hot-air type reflow furnace, the flux contained in the cream solder is washed away in a washing process and surface oxides are removed in a hydrogen plasma treatment process performed after the washing process. Then, after bare chip ICs are fixed with a boding agent in a bare chip bonding process, wire bonding pads are connected to each other with aluminum wire by using a ultrasonic wire bonder in a wire bonding process. Finally, wire bonded sections are sealed with a silicon resin in a sealing process. Therefore, electronic circuits can be mounted on an inexpensive glass epoxy substrate having high hardness and excellent wire boding property.

     USE: Inhibitors of glycosidase enzymes in biological fluid.  
     PROCESS: D-Glycero-D-alo-heptono-1,4-lactone is reacted with 2,2- dimethoxypropane to give a fully protected lactone. The acetonide group at C-6,7 is removed to produce a C-2,3 protected heptonolactone. The product is reacted with a silyl blocking agent to protect the primary OH, yielding a C-2,3,7 protected lactone. The protected lactone is reacted with a 2,2- dimethoxypropane and the resultant product is reacted with fluoride ion to cleave at C-7. The obtained alcohol is esterified with triflic anhydride, which is then reacted with azide ion. The product is reduced and reacted with methanesulfonyl chloride. The product is catalytically hydrogenated, heated in the presence of sodium acetate to give a tetra cyclic pyrrolizidine, and the acetonide pretecting groups of the tetracyclic pyrrolizidine are removed by acid hydrolysis to give the (1S,2R,6R,7S)-1,2,6,7-tetrahydroxypyrrolizidine.
