Patent JP-H05152526-A (JP)
Title: Semiconductor integrated circuit device
Inventor: NUNOKAWA YASUHIRO
IPC: H01L27/088
Filed: 1991-11-30
Abstract: PURPOSE:To prevent damage of an element due to an excess current by providing a switch element to be switch-controlled based on a ground potential or an operating voltage to be supplied from an external terminal, and supplying an operating voltage of the ground voltage to an isolation region due to a P-N junction isolation type. CONSTITUTION:At the time of a reverse connection of a power source in which a ground potential of a circuit is supplied to an element VDD and a positive power source voltage is supplied to a terminal GND, a switch MOSFETQ2 is turned OF in response to the ground potential of the circuit to be supplied from the element VDD. Therefore, since a DC current path formed of the terminal GND - the switch M0SFETQ2 - a parasitic diode Di - the terminal VDD is cut OFF by the OFF state of the MOSFETQ2, damage of an element due to an excess current to the diode D1 can be prevented.

Abstract: PROBLEM TO BE SOLVED: To prevent an image quality from being deteriorated, while equalizing peripheral speed of the image carrier and the traveling speed of a recording medium by respectively providing first and second generating means for generating first and second speed corresponding value, and controlling means for performing control of driving means of the image carrier in order to equalize the first and second speed corresponding value. SOLUTION: A rectangular wave WA constitutes the first speed corresponding value corresponding to peripheral speed of a photoreceptor drum, and the rectangular wave WB is the transporting speed of a transporting belt, that is, the second speed corresponding value corresponding to shifting speed of a recording medium. Moreover, a wave shape forming device 41 constitutes a first producing means, and the reference space generating device 42 constitutes, the second producing means. The angular speed ω1 of a motor 45 is controlled so that a phase of the rectangular wave WA matches with the rectangular wave WB. Thus, the peripheral speed of the photoreceptor drum and the shifting speed of the recording medium can be equalized, therefore the toner image transferred on the recording medium is prevented from the occurrence of disturbance, slippage, or the like.  Accordingly, the image quality is free from deterioration.

Title: Multiplex-electrode type biosensor and manufacture thereof
Inventor: HI JIN RI
IPC: G01N27/327
Filed: 1995-12-08
Abstract: PROBLEM TO BE SOLVED: To measure more correctly in a single measurement by constituting a sensor of a plurality of active indication electrodes, an inert indication electrode for correcting surrounding signals, and an opposite electrode and a reference electrode. SOLUTION: An electrode that can generate two or more signals to the same sample at the same time when the sample is measured once by a single sensor is obtained. Signals generated simultaneously to the single sample are read by a multichannel potentiostat, and then an average value is calculated. Since many indication electrodes (6a1-6a3) are set on a biosensor using a biological substance to generate signals when reacting to a specific substance, the same effect is obtained as when several independent measurements are repeatedly carried out a plurality of number of times in one measurement thereby to obtain an average. Accordingly, the reliability in all measurements using the biosensor is ensured.
