Title: Modifying method of woody material
Inventor: SHIRAISHI NOBUO
IPC: B27K5/00
Filed: 1981-08-24
Abstract: PURPOSE:To obtain a woody material having improved thermoplasticity causing the melting under heating, by treating the woody material with a reactant, e.g. an esterifying agent, grafting the treated woody material, making the woody material amorphous, swelling the material, and impregnating the woody material with a polymerizable substance. CONSTITUTION:A woody material is treated with a reactant reactive with the hydroxyl groups in the woody material, e.g. an esterifying agent or etherifying agent. A polymerizable substance, e.g. monomer, oligomer or prepolymer of a vinyl compound, is grafted onto the treated woody material to modify the woody material. The graft copolymerization is carried out by the conventional method, e.g. impregnating a radical polymerization catalyst, e.g. hydrogen peroxide or benzoyl peroxide, and the polymerizable substance into the woody material, and radically polymerizing the polymerizable substance. The modified woody material can be molded into an optional shape by applying heat and pressure thereto.

IPC: H01P1/39
Filed: 1977-11-07
Abstract: PURPOSE:To perform broad band, by using the material high in permeability as the impedance converter. CONSTITUTION:The input high frequency power from one port is appeared at either of adjacent ports depending on the direction of the DC magnetic field determined with the permanent magnets 3, 3' provided external the waveguide 1 through the difference of the positive and negative rotary permeability of the ferrite 2. The dielectric substances 4, 4' are placed up and down the ferrite 2 and they are inserted in the waveguide 1 together with the impedance converter 6. Further, the converter 6 consists of high permeability material, the DC magnetic field formed with the magnets 3, 3' is concentrated to the ferrite 2, increasing the magnetic field of the ferrite 2. As a result, Q at the branch point of the tube 1 is lowered and broad band can be obtained.

Title: Running power transmission gear for tractor
Inventor: KATAYAMA NOZOMI
IPC: B60K23/08
Filed: 1989-05-26
Abstract: PURPOSE:To facilitate turning with switch-over automatically made between four wheel drive and two wheel drive by providing an automatic switch-over means which automatically transmits power to a front wheel power transmission shaft based on the ground speed of rear wheels. CONSTITUTION:Power is transmitted to a driven body 37 from a trailing end power transmission shaft 29 of a change gear mechanism via the spline shaft 30 of an outer package, the sliding cam 39 of a drive body 41, the sliding cam 39 of a slider 40 and both of clutch pawls 36, and is furthermore transmitted to a front wheel input shaft from the driven body 37 via a driven shaft 35. When the braking operation of one side rear wheel forces the ground running speed of the other side rear wheel to be doubled through the action of a rear wheel differential mechanism at the time of turning a tractor, front wheels are pushed so as to be advanced, reverse transmission from the front wheels thereby permits a gap to be made between the driven surface of the sliding cam 39 of a slider 40 and the drive surface of the sliding cam 39 of the drive body 41, and the clutch pawl 36 of the slider 40 comes off from the clutch pawl 36 of the driven body 37 with the slider 40 slid so that the front wheels are conditioned to no power transmission. After turning has been over, when the ground speed of the rear wheel is restored to normal ones, both of the clutch pawls 36 are meshed with each other so that the front wheels are conditioned to power transmission.

IPC: D06F33/02
Filed: 1990-05-25
Abstract: PURPOSE:To make it hard to cause excessive unbalance and to reduce the safety switch operation rate remarkably by controlling to automatically select and set stirring having shorter reversing time interval than ordinary washing and rinsing stirring from plural time intervals, corresponding to the amount of clothes in the latter half of washing and rinsing stirring. CONSTITUTION:When a power supply switch button is pressed to turn on a power supply switch and a button of an external operation switch is pressed, according to a signal from a controller, an electric current is applied to a water supply solenoid valve and an electric current is applied to a washing-dewatering vessel. At this time, an electric current is also applied to a solenoid to enter a dehydrating mode, so that an electric current is applied to a motor 8 in such a manner as to turn on 0.5 seconds and turn off 0.4 seconds, whereby the washing-dehydrating vessel 5 is turned gently in one direction to uniformly splash water of water supply on washed materials in the vessel. The cloth untangling stirring time interval is made shorter in case of a small amount of clothes and near the rated load, stirring is performed a little more strongly than at the time of small load, so that the stirring force can be applied to the whole of clothes to increase a balancing effect. Thus, effective balanced stirring can be performed extending from small amount to the rate load.

Title: Method of treating product on bottom of tower through extraction distillation method for recovering pure hydrocarbon
Inventor: GERUHARUTO PUROISAA
IPC: C07C7/08
Filed: 1981-08-28
Abstract: A method for working up residues of an extractive distilling process for obtaining pure hydrocarbons. The residue from an extractive distilling column is fed to the about middle part of a distilling column. The hydrocarbons are distilled and removed at the head of the distilling column and the solvent is removed at the bottom of the distilling column. A sidestream is removed from the distilling column at a position above the feed plate for the residue from the extractive distilling column via a so-called reflux evaporator plate having an elevated level of liquid. The sidestream is heated by indirect heat exchange with the solvent flowing from the distilling column. The heated-up sidestream is fed back into the distilling column at a level at or above the reflux evaporator plate. The concentration of the solvent at the reflux evaporator plate is controlled by the amount of reflux at the head of the distilling column. The heating of the side stream reduces the heat requirement of the bottom boiler of the distilling column by about 35 percent.

Title: High frequency amplifier
Inventor: ISHII MASANORI
IPC: H03F3/189
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To reduce the amplification gain to suppress generation of a high frequency even in the case of a signal having a high frilled intensity by providing a transistor TR which controls the current to the amplification element in accordance with an AGC signal and adjusting the impedance by its current change. SOLUTION: An impedance adjustment circuit 14 where coils L2 and L3 formed one core are connected in series obtains a large inductance by coils L2 and L3 when the current of the drain, which is connected to the emitter of a TR2, of an amplification element TR1 using a junction field-effect transistor is small. When this drain current is large, the current 14 obtains a small inductance due to the coil L3 by magnetic saturation of the core in a part forming the magnetic path of the coil L2. Consequently, the adjustment circuit 14 has a low impedance for the large drain current of the amplification element TR1 and has a high impedance for the small drain current of the amplification element TR1, thus impedance adjustment is made possible.
