Title: Power transmitting device
Inventor: TERAOKA MASAO
IPC: F16D35/00
Filed: 1986-03-26
Abstract: PURPOSE:To prevent sealing materials etc. from being damaged by restricting any relative rotation between rotating discs by means of a simple structure by bringing, in contact with the inside wall of a case, the outside wall of an enclosed chamber containing said discs to be connected to both transmission shafts and viscous fluid. CONSTITUTION:In a differential gear case 1, a large diameter sleeve 5, a side plate 7, and a flanged sleeve 9 are installed, said side plate 7 and said sleeve 9 being fitted on shafts W1, W by splines 19, 17 respectively. An enclosed chamber 3 is made liquid- tight with sealing members 13, 15 and filled with silicone oil. One end of said large diameter sleeve 5 is connected with the flange 9a of said sleeve 9 in one body. Rotating discs 25, 27 are locked respectively to said large diameter sleeve 5 and a collared sleeve 11. When the relative rotation between said discs 25, 27 continues and heat is generated, the temperature of said silicone oil rises until increased internal pressure and thermal expansion of said enclosed chamber 3 cause frictional torque between said enclosed chamber 3 and differential gear case 1 through controlling member 29. The relative rotation between the discs is thus restricted by the above-mentioned simple method, and possible damage of sealing materials can be prevented from occur ring.

Title: Liquid crystal constitution having polychromatic coloring matter
Inventor: FERGASON JAMES LEE
IPC: G02F1/1333
Filed: 1991-03-29
Abstract: PURPOSE: To effectively execute a transparent state and opaque state to switch without requiring a special treatment for regulating the orientation of liquid crystal molecules and to facilitate manufacture with a simple structure by using a liquid crystal material which is nematic in effect and has positive dielectric anisotropy. CONSTITUTION: First and second electrodes 13, 14 are arranged on both sides of the liquid crystal material 20, existing between a pair of substrates 12 in order to impress electric fields. One thereof is formed transparent, and the other in a patterned form. The incident light on a liquid crystal constituting body 11 is scattered by the liquid crystal material 20 as the liquid crystal material 20 is affected in the orientation by the capsules 22 of the polymer structural body, when the electric fields are not impressed on the electrodes. Simultaneously, the multichromatic dyestuff included in the liquid crystal material 20 orients in the direction of the liquid crystal material 20 as well and, therefore, the absorption of the light by the multichromatic dyestuff is increased, and the liquid crystal constituting body 11 is made colored and opaque.  The liquid crystal material 20 and the multichromatic dyestuff orient nearly toward the electric fields, when the electric fields are impressed. The scattering of the light is then reduced, and the liquid crystal constituting body 11 is made transparent.

Title: Microprocessor system
Inventor: YANAGIDA HIROMI
IPC: G06F9/06
Filed: 1990-03-16
Abstract: PURPOSE:To adds an auxiliary memory and then correct a main memory without replacing the main memory by comparing address data that a comparing circuit sends to the main memory with data stored in registers, and making the auxiliary memory active when the address data indicates a corrected area. CONSTITUTION:When a microprocessor 4 sends out the address data so as to read data out of the main memory 1, the comparing circuit 6 compares the high-order digit bits of the address data with data stored in the registers 5A and 5B. When there is matching data, it is judged that the data indicates the corrected area, the block of the auxiliary memory 2 including the corrected area is specified, and a signal which makes the main memory 1 active is sent to the auxiliary memory 2 to read data out. When there is no matching data, it is judged that the data indicates a part which need not be corrected and an active signal is sent to the main memory 1 to read data out of the main memory 1. Consequently, a ROM stored with a program is corrected partially.

Title: Control mechanism for waveform display
Inventor: NAKAMURA HAJIME
IPC: G01R13/20
Filed: 1994-04-05
Abstract: PURPOSE:To eliminate contradiction between a display immediately after modification and a displayed waveform by designating a point to be modified and an execution request using a command for modifying the setting, erasing the waveform being measured and displayed under the conditions prior to modification, invalidating the measurement data until a waveform is measured and displayed under new setting conditions,and delivering an alarm message upon request of a measurement CONSTITUTION:Upon receiving an instruction for modifying the setting at a key input section 1 or a communication command processing section 2, a command processing section 3 rewrites a setting information table 4 and notifies the modified parts to a command executing section 5. The executing section 5 decides whether erasure of currently displayed waveform is needed and if it is needed, an erasure command is fed to a display section 11. Measurement is then started under new setting conditions and the measurement data is invalidated until a waveform is displayed. If an instruction requesting a measurement data is received, an alarm message 15 delivered. This mechanism eliminates contradiction between the display of setting conditions immediately after modification thereof and a displayed waveform.
