Title: Debug controller
Inventor: ISHII HIDESHI
IPC: G06F11/28
Filed: 1988-12-01
Abstract: PURPOSE:To easily execute the debug of an exception which is illegally produced by a designing mistake, etc., by using an arithmetic unit which detects the exceptions like a overflow, etc., a coincident address comparison register, a comparator, an AND gate, etc. CONSTITUTION:When an overflow exception is produced and detected by an arithmetic unit 3, the start address of an exception process routine is given to a control memory 1 via a decoder 14, a signal line 103, and a microaddress production circuit 4. Thus the exception process routine is carried out. Then the address designated by a coincident address comparison register 8 is set at a microaddress trace register 5 during execution of the exception process routine. Thus a comparator 10 detects the coincidence and 1 is outputted to an AND gate 12. Then the gate 12 outputs 1 to the unit 3. Thus the working of the device 3 is stopped and at the same time the discontinuation of working of the device 3 is reported to a service processor 13. As a result, the debug is facilitated to an exception which is illegally caused by a designing mistake, etc.

Title: Liquid crystal display element
Inventor: MURATA MASAMI
IPC: H05K3/36
Filed: 1990-11-09
Abstract: PURPOSE:To improve the reliability of a liquid crystal display element by packaging a drive IC using a flexible tape having a bent section of high mechanical strength and resistance even against a long-term temperature cycle test. CONSTITUTION:A so-called double layer tape comprising a polyimide tape 7 plated with copper 6 via an additive has high adherence strength of polyimide and copper foil, and has no an adhesive layer. Consequently, the double layer tape is low in rigidity and easy to be bent, thereby allowing the polyimide on the copper foil to be lined at a bent section. Also, in order to improve the bending quality of the bent section, a row of holes 8 are drilled through the polyimide or the width of a copper foil pattern is made smaller than the width of other sections as a method for weakening the rigidity of the polyimide and copper foil at the bent section. According to this construction, a liquid crystal display element of high reliability can be embodied by packaging an IC drive 4, while using the double layer tape having a row of holes drilled through the polyimide or a fine copper foil pattern at the bent section.

Title: Self-running device in pipe
Inventor: FUSE EIICHI
IPC: B61B13/10
Filed: 1990-11-09
Abstract: PURPOSE:To precisely control the running operation with a simple structure by controlling a driving voltage applied to a piezoelectric element, and moving a moving member by utilizing the inertial force of an inertial body at the time of extending and contracting the piezoelectric element in its axial direction and a frictional force received by the moving member. CONSTITUTION:When a high driving voltage is momentarily applied to a piezoelectric element P to quickly extend the piezoelectric element, a moving body M and an inertial body (m) are simultaneously moved in opposite directions, and the moving body M is moved forward by a distance  m1 while receiving a dynamic frictional force. When the applied voltage to the piezoelectric element P is reduced to contract the piezoelectric element P, and the inertial body (m) is slowly pulled back on the moving body M side, the moving body M is reduced in speed so that it is held by the frictional force with a base B and stopped. When the electrification is quickly stopped to quickly stop the movement of the inertial body (m), the inertial body (m) is collided with the moving body M, and the whole of a self-running device overcomes the frictional force, starts advancing, moves until the kinetic energy is lost by the dynamic frictional force of the moving body M, and stops. Thus, it is moved forward by a distance  m2.

Title: Diagnostic method for insulation of power cable line
Inventor: HIYAMA SHOICHI
IPC: G01R27/18
Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To diagnose the insulation of a power cable line with accuracy without dividing the line into the cable of each section by connecting a switch to each grounding line from the shielding layer of the cable in each section and connecting a common insulated wire for measurement to the connecting points between the shielding layers and switches. SOLUTION: A cable line 1 is set to an AC-applied state by closing a switch 8 and loads are disconnected from the line 1 by opening load switches 5a-5c. When switches 11a-11c are opened and, for example, switches 10a and 10c are opened and only a switch 10b is closed, a leakage current is generated between a cable conductor 2 and a shielding layer 3 and flows to a grounding line 9b in case the insulating state of a section 1b is deteriorated. Therefore, the leakage current is measured with a measuring instrument 14 connected between an insulated wire 13 for measurement and the grounding line 9. When this diagnosing method is used, even a long cable line can be diagnosed for insulation with accuracy without dividing the line into the cable of each section 1a-1c and, in addition, no restoring work is required after completing the diagnosis.

Title: Active type suspension for vehicle
Inventor: TAKAHASHI KENRO
IPC: B60G17/056
Filed: 1990-11-09
Abstract: PURPOSE:To save the energy by inserting a flow passage opening/closing mechanism which permits the inflow of the working liquid into a supply port from an output port, into a bypass flow passage for the communicate between the supply port and the output port of a pressure control valve, when the pressure at the output port becomes over the pressure at the supply port. CONSTITUTION:During the brake application for rolling, if a vibration force having a relatively large amplitude is inputted only on an inner wheel (left wheel) side, because of a projection on a road surface, the internal pressure is increased through the compression of the working oil in a cylinder L, and the control pressure on the left wheel side increases larger than the supplied pressure. Then, a check valve 66 which makes a detour around the pressure control valve 40FL on the left wheel side, e.g. a front wheel, is opened, and the working oil in the cylinder chamber L as output side and the working oil of the inside which communicates to the cylinder chamber L is returned to the feeding port side of the pressure control valve 40FL through a bypass pipe 64 and the check valve 66, and the supplied pressure starts increase. Accordingly, the supply pressure increases, and at the same time, the supplied pressure P is consumed on a right wheel side.

Title: Data card and reader/writer
Inventor: SAITO YASUO
IPC: B42D15/10
Filed: 1989-11-25
Abstract: PURPOSE:To prevent the data card from being forged even if whose recorded data is simply copied by providing an identifier at a place other than normal recording data. CONSTITUTION:The additional code identifier 3 is printed at the optional position on the magnetic card 1, e.g. at a left lower position while mixed up with the pattern on the top surface. When the magnetic card 1 is inserted into the head part 5 of the reader writer 4, an identifier reader 8 detects the additional identifier 3 and outputs the pattern of the identifier 3 to a selector 10. The selector 10 switches a switching terminal 11 corresponding to the pattern of the identifier 3, selects and accesses the additional code in a memory 12, and outputs the code to be added to the recording data to a code arithmetic part 13. The pattern of the identifier 3 is not recorded in the selector 10 and when this card is not a regular magnetic card 1, the recording data is not written and the magnetic card 1 is ejected. Consequently, the data card is prevented from being forged.
