IPC: H01L29/10
Filed: 1995-10-23
Abstract: PROBLEM TO BE SOLVED: To provide a vertical-type semiconductor device, and its manufacturing method, having a low on-resistance of a source region and a high withstand voltage of a P body region together. SOLUTION: A vertical-type transistor has sidewall silicon oxide films 17a on the sidewalls of a gate electrode 13 and a silicon oxide film 14. Accordingly, it is possible to make an on-resistance sufficiently small even if the impurity concentration of an N<+> source region is low, since it is possible to shorten the distance between the gate electrode end and the contacting end of a source electrode 19 with an N<+> source region 15. The concentration of the N<+> source region is lower than that of a P<+> body region 18, and is about ten times or more as high as that of a P body region 16. Accordingly, the depth of the N<+> source region does not become too deep, and the base width of a parasitic bipolar transistor to the P body region is kept at a proper value. And a punch through voltage in the P body region becomes high, and it becomes possible to make the withstand voltage high.

Title: Recovery action control of ink jet printer
Inventor: TANAKA SOHEI
IPC: B41J2/175
Filed: 1989-10-22
Abstract: PURPOSE:To make it possible to allow a non-discharge process of universal applicability at high speed under a small-scale circuit configuration by controlling CPU so that the timing of writing data in a register for non-discharge process data is synchronized with an image clock. CONSTITUTION:A bubble jet writing head of four colors such as cyan, magenta, yellow and black is incorporated in a carriage 1. This head has 128 nozzles and performs a non-discharge process at a rate of once every four times to write non-discharge process data in memory. However, in this case, the discharge can be completed in about one second by performing the discharge instantaneously following the preceding discharge while writing non-discharge process data. CPU runs an interruption routine each time VE reaches a falling edge, but sets F/non-discharge process as 1, using a non-interruption routine, if the time for non-discharge process comes. Then CPU sets the frequency of non-discharge processes in a counter, then decrements a non- discharge process frequency counter each time a non-discharge process is performed. In this case, if the non-discharge process frequency counter indicates 0, CPU stops the non-discharge process when the F/non-discharge process is set as 0 and then an interruption routine is executed. As a result, it is possible to perform the non-discharge process of universal applicability under a small-scale circuit configuration.

CONSTITUTION:The exposure device is provided with the rotation energizing means 12 and the control means 11. The rotation energizing means 12 energizes the rotation of the rotary polygon mirror 13 in both normal and reverse directions; the control means 11 controls the direction in which the rotation energizing means 12 energizes the rotation of the mirror 13, according to a signal A which specifies either the normal image exposure or mirror image exposure. Since the rotary polygon mirror 13 rotates in normal and reverse directions, a normal image or a mirror image can be exposed onto a photosensitive body by switching a rotating direction. Thus, the normal image or the mirror image is selectively exposed by means of the simple structure and without changing a picture signal transmitter, by switching the rotary polgyon mirror between the normal and reverse directions and rotating it to carry out exposure.
