Title: Power transmission device for four-wheel drive
Inventor: TAKAMIYA BONNOSUKE
IPC: F16D41/06
Filed: 1985-04-16
Abstract: PURPOSE:To make overtorque to be required at the time of an emergency escape transmittable, by constituting a one-way clutch so as to be engaged at a time when both front and rear wheels come to a constant revolving speed ratio, in case of a device, bearing the above caption, provided with an oil pump in a power transmission system of one side of these front and rear wheels. CONSTITUTION:A one-way clutch 24 is constituted so as to make a clutch off but in time of reversion to be locked when its inner ring part rotates speedier than the outer ring part (unillustrated herein). And, a suboutput gear 21 is always rotated at a constant transmission ratio of i2/i1 to a front wheel casing 30, making the outer ring part of the one-way clutch 24 rotate all the time. Thereafter, while the inner ring part of the one-way clutch 24 via an output shaft 9 at the rear-wheel side rotates speedier than the outer ring part, the clutch is off. However, if each rotation of both wheels 4 and 5 becomes equal in time of an emergency escape, the clutch 24 comes into a state of being engaged whereby the clutch 24 transmits the torque. With this constitution, overtorque at the emergency escape is transmittable.

Title: Foundation structure in liquefaction ground
Inventor: NAKAYAMA KATSUMI
IPC: E02D27/34
Filed: 1993-04-08
Abstract: PURPOSE:To enhance economical efficiency and execute construction work in a short time by eliminating the need for increasing the strength of a foundation pile or executing a soil improvement in a wide area. CONSTITUTION:The vertical load of a building 3 on a liquefaction ground 2 is supported with a foundation pile 5 which reaches a non-liquefaction ground 4b. A horizontal force acting on the building is transmitted to the non-liquefaction ground with a wall-shaped soil improvement body 6 created in the liquefaction ground. The scope of soil improvement of the soil improvement body 6 is limited so a plane and band-shaped area as a minimum requirement and the soil improvement body 6 is laid out in such a fashion that if may not mix with a foundation pile so as to conform to the plane shape of a building. The foundation pile 5 is capable of reducing an increased forizontal force with the soil improvement body 6 and assuming that only vertical load is designed as a main design load, thereby enhancing economical efficiency. The soil improvement body 6 minimizes an improvement range for horizontal force transmission and provides more profitable economic efficiency and construction period compared with the over-all improvement structure of a construction site. Furthermore, since the soil improvement body 6 and the foundation pile 5 are mixed with each other, the previous and subsequent steps of both work are free of any restrictions while there is no need to worry about any damages in the soil improvement body or the foundation pile in both works.

IPC: G03G15/01
Filed: 1981-05-29
Abstract: PURPOSE:To obtain a uniform two-color toner image on a recording paper, through the case of by decreasing the absolute value of the toner the polarity of toner charge of which is inverted than the absolute value of the specific charge of the other toner, and making alignment of toner specific charge after the pre-charge easy. CONSTITUTION:When a negative toner with smaller specific charge, e.g. -11muO/ g, than the conventional specific value of -18muO/g is used, the toner specific charge is around 22muO/g with the positive pre-charge and the value remarkably approaches the specific charge of the positive charge. If the specific charge of the negative toner is further smaller, although the specific charge of the positive and negative toners is further arranged, but the charge is <=-5muO/g, then the electrostatic force between the toner and the carrier is weaker, the toner is scattered from a developer through the rotation of a magnetic roller of the developer and the dirt on the background is generated. Thus, the value cannot be <=-5muO/g.

Title: Input pen for ultrasonic tablet
Inventor: INOSE SHIGERU
IPC: G06F3/03
Filed: 1985-04-19
Abstract: PURPOSE:To obtain an ultrasonic tablet of high precision by securing the follow-up of the tip displacement of a pen point to the applied voltage and therefore eliminating the misinput produced by the reverberation amplitude when an input pen has a slow contact with the tablet surface. CONSTITUTION:When the voltage is applied to a piezoelectric element 2, the element 3 is extended up and down. This displacement of the element 3 is slightly absorbed by a damper 2 such as the hard rubber 1t, etc. However most of said displacement is transmitted to a pen point 4 owing to a large amplitude. The reverberation of the pen point 4 and the element 3 have small amplitude and are absorbed by the damper 2. Therefore the displacement amount of the tip part of the point 4 follows well the voltage applied. Both the material and the thickness of the damper 2 are decided by a desired amount of the displacement and the voltage applied. Then the damper 2 can be omitted as long as a pen case 1 is made of plastic, etc. which is acoustically soft.
