Title: Method of cleaning semiconductor wafer
Inventor: SHIOTANI SHINICHI
IPC: H01L21/304
Filed: 1996-10-14
Abstract: PROBLEM TO BE SOLVED: To prevent wafer marks caused by moisture remaining on the silicon surface. SOLUTION: Parts of oxide films (SiO2 ) 2 and 3 are exposed on a silicon wafer 1. The oxide film (SiO2 ) 3 is removed by chemical treatment by applying hydrofluorocarbon(HF) aqueous solution. Hydrogen peroxide aqueous solution containing 1-10% of hydrogen peroxide (H2 O2 ) is poured onto the surface of the silicon wafer 1 for about 1-20 minutes to form a silicon dioxide layer 4 which is 10-30Å thick. The silicon wafer 1 is cleaned by pure water in order to completely remove the hydrogen peroxide used as a chemical agent. After cleaning with pure water, moisture 5 remains between the silicon dioxide layers 4. Since the silicon dioxide layer 4 is hydrophilic, the moisture, instead of forming spherical water drops, forms a thin and uniform layer adhering to the silicon dioxide layer 4. The silicon wafer 1 is rotated for removing the moisture 5.

Title: Projection type display device
Inventor: TANIGUCHI SHINICHI
IPC: H04N5/44
Filed: 1993-11-18
Abstract: PURPOSE:To view an image in a short time when an LCD panel is active although the power source is turned OFF by counting the nonillumination time of a light source and setting a video mute time at the time of reillumination on the basis of the counted time. CONSTITUTION:A timer circuit 13 inputs data on the nonillumination time obtained by a control circuit 7 with the signal from an illumination detecting circuit 8 and counts the nonillumination time. When the power source is turned ON immediately after the power source is turned OFF by an operation part 12, a video mute period is shortened to the time counted by the timer circuit 13. When a voltage is supplied at the time when sufficient cooling is done after the voltage is supplied, namely, when the power-OFF time exceeds the stable time of an LCD panel 3, a video signal is made effective the stable time after the reillumination of a light source 5'. Consequently, color unevenness of the LCD panel at the power-ON operation is not displayed, the video mute time can be varied corresponding to the power source disconnection time, and video muting can be performed in a minimum time.

Title: Shell type image forming device
Inventor: SAKAGUCHI NORIHISA
IPC: B65H7/06
Filed: 1990-10-25
Abstract: PURPOSE:To make an original escape by a comfortable margin when a sheet is clogged by receiving a signal from a sheet clogging detection means and sending an opening command after a predetermined time to open a device main body dividing into two units by an opening and closing mechanism. CONSTITUTION:When a sheet is clogged in a transfer route 32, ON signal is inputted once from a sensor S2 to a sheet clogging detection means 50, but ON signal is not inputted from a sensor S3 even after several seconds have been collapsed and, therefore, the detection means 50 judges that the sheet is clogged and sends a signal for clogging to a control means 51 and a warning means 52. The warning means 52 warns the operator of sheet clogging according to it. On the other hand, the control means 51 starts to count the time T upon receiving its signal and the operator makes the original escape during that while. After the time T is passed, the control means 51 applies voltage to a solenoid 19 and the solenoid 19 moves an opening and closing mechanism to open the device main body dividing into two units.

Title: Recording paper feeder in recorder
Inventor: TEZUKA KIYOTO
IPC: B41J11/42
Filed: 1986-12-05
Abstract: PURPOSE:To exactly detect the abnormality in paper feeding by a method in which the first pulse signal corresponding to the revolving number of motor and the second pulse signal of clock pulse are put in an incremental decremental counter, and on the basis of the count values, the normality or anomaly of paper sending is judged. CONSTITUTION:In making a power source, the initial value of an incremental/ decremental counter 14 is set up by a comparison reference count value circuit 15. When a desired speed is set up by a speed setting circuit 11, the output of a reference pulse oscillator 9 is divided by a divider 10 and sent out as a pulse signal. In case a DC motor 3 is stopped due to the blocking of paper, pulse signal from a photocoupler 8 disappears and only pulse signal from the divider 10 is applied to the counter 14. The count values can thus be counted and anomaly signal of paper feeding is sent out at a time when a comparison reference value is exceeded in a monitor 17, and the power source circuit 20 of the DC motor 3 is turned OFF.

Abstract: PURPOSE:To make improvements in responsiveness at the time of transition to a supercharging operating state by making a second supercharger prerotatable at a driving range where it is set to a dormant state, in an engine which is provided with a first supercharger normally driven and the second supercharger being driven only at a specified driving range. CONSTITUTION:At a low-speed, low rotation range, an exhaust cut valve 5 is closed, and a first supercharger 1 alone is operated. In this case, when a driving state has shifted to the high flow side from the low flow side, first an exhaust shifting valve 8 is selected to open from close, then a relief valve 24 to open from close as well, and also the exhaust cut valve 5 to open from close in order, respectively. With this operation, a second supercharger 2 is operated, thereby enhancing the extent of supercharging efficiency at the high flow range. In brief, at time of the said transition, in advance of open operation of the exhaust cut valve 5, an exhaust shifting valve 11 is opened where by the second supercharger 2 is made into prerotation, and afterward, the relief valve 24 is closed, thus an increase in rotational frequency of the second supercharger 2 during prerotation is accelerated, and the said transition is smoothly performed with no shock.
