Title: Contact reliability evaluation device for mechanical contact
Inventor: IKEGAYA TAKEHIKO
IPC: G01R31/00
Filed: 1998-05-19
Abstract: PROBLEM TO BE SOLVED: To realize a quantitative evaluation of a deterioration degree of a contact and a contact reliability of a life by taking in an unstability of a contact resistance as a data and also detecting an oxide film rupture point. SOLUTION: In a contact resistance measurement of a contact 4, a measuring current I is increased in turn from 0 to the maximum rated current Imax at a resolving current value interval and a contact voltage Vr of the contact 4 in the respective current values is continuously measured. Thereby, a personal computer 7 obtains an I-Vr characteristic figure and can detect not a point that the contact voltage Vr of the contact 4 slightly swings as an oxide film rupture point in the I-Vr characteristic of the contact having an unstable contact of B in the same figure, but a point that the contact voltage Vr of the contact 4 rapidly and outstandingly decreases.  Thus, by gradually increasing the measuring current I, the contact voltage Vr of the contact B having an unstable contact exceeds a normal contact, further outstandingly exceeds a threshold value, abnormally becomes higher and easily exceeds the oxide film rupture voltage of the contact 4. As a result, a required characteristic figure is obtained, the oxide film rupture point of the contact 4 can be detected and the contact stability of the contact 4 can be judged.

Title: Reader printer
Inventor: KASHIWAGI KAZUO
IPC: G03B21/11
Filed: 1980-09-30
Abstract: PURPOSE:To achieve printing with nearly constant exposure illuminance at any time, by barying the luminous brightness of a lamp according to the F number of a used lens. CONSTITUTION:When the magnification of porjection is changed by changing a projection lens used for a reader-printer, a changeover switch SW is placed at the side of a resistance R, having a corresponding number, corresponding to a used lens. This resistance R has a resistance value matched with the used lens so that even when any lens is in use, illuminance in exposure is nearly constant. Thus, the illuminance on a printer surface is kept constant by changing luminous brightness, so a user determines the amount of exposure in conformity to only the density of a microfilm, so that a copy adjustment free of wastage is made.

In the case where the received one is proven to be the ID code, printing is made in the forward direction on printing paper with printing pressure higher than that of normal character code. Then checking is made by reading through an ID sensor (IDS) 43 provided in a printing head (PHD) 14 on the ID code data printed in the above- mentioned printing process with a spacing motor (SPM) 27 turned in the reverse rotation. In the case where the result of comparison made between the ID code received from the MCT 41 and the ID code read out on the checking is 'N', the PHD 14 is moved back to the previous position of printing, and the printing is made again in the forward direction with the printing pressure much higher than before, and checking of the ID code is made with the speed for checking by reading in the reverse direction made slower. Then the judgement on the comparison is made again.

IPC: H01L21/822
Filed: 1988-06-06
Abstract: PURPOSE:To improve flatness, by filling a groove with an N<+>-type polysilicon conducting layer consisting of at least two or more polysilicon layers while interposing an insulating film between these polysilicon layers. CONSTITUTION:A capacity consisting of a dielectric film 8, an N<+>-type polysilicon conducting layer 18, an insulating film 19 and a polysilicon conducting layer 20 is formed on a groove formed in an Si substrate 1 having an epitaxial layer 3. A field SiO2 layer 4 comprises oxide films of the N<+>-type polysilicon conducting layer 18 and the polysilicon conducting layer 20, so that it serves as an insulating/isolating film for isolating the capacity electrode from a word line 11B of an adjacent cell. Since the N<+>-type polysilicon conducting layer 18 and the polysilicon conducting layer 20 are isolated from the word line 11B of the adjacent cell by the thick field SiO2 film 4, a memory cell thus obtained is allowed to have sufficiently high dielectric strength and the word line capacity can he decreased. Any allowance is not needed for working the N<+> polysilicon conducting layer 14 or for registering it with the connecting section, and this fact enables the memory cell to be constructed finely. In this manner, the flatness is improved while the memory cell can be constructed finely.

Title: Method and device for monitoring electric discharge machining process of electric discharge machine
Inventor: KAARU ZEERIIDAA
IPC: B23H1/02
Filed: 1987-05-29
Abstract: A method and device for monitoring a spark-eroding process in a spark-eroding machine, in which the impulse voltage curve is measured in the working gap and, when the actual voltage curve differs from a desired voltage curve, a control command is produced which changes the process data of the eroding machine. The voltage impulses are thereby, depending on the occurring ignition delay unit (td), associated with different impulse groups which are each characterized by a pregiven ignition delay range. The impulses occurring in each impulse group are counted and a control command is produced when a pregiven limit number of successive impulses of one impulse group is exceeded indicating a process degeneration. The control command changes the process data of the eroding machine in the sense of a normalization of the process.
