Inventor: TOKUNAGA KAZUHIKO
IPC: H01L21/31
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To form a protective oxide film having substantially the same high quality as a thermal oxide film as a protective film in the deposition of a gate oxide film formed of a silicon oxide film. SOLUTION: In the case of depositing a silicon oxide film on a silicon substrate surface using this method, first, a natural oxide film which is produced in cleaning a substrate is removed by acid washing and a protective oxide film is again formed on the substrate surface with an oxidizing agent. Next, when the substrate is introduced into a heat-treating region 12 in an oxide film-depositing equipment 10 for depositing a silicon oxide film on the substrate surface with the protective oxide film, the heat-treating region 12 is blocked from the outside with nitride flow curtains 32 and 34, a chlorine contained nitride gas is flowed into the heat-treating region 12 and the substrate is introduced into the heat-treating region 12, while the substrate is exposed to the chlorine contained nitride gas atmosphere.  Subsequently, a water vapor contained oxidative gas is introduced into the heat-treating region 12, and a silicon thermal oxide film is deposited on the substrate. Next, the substrate is annealed by introducing the chlorine contained nitride gas into the heat-treating region 12.

Title: Drive method for charge transfer element
Inventor: OZUMI TAKEHIKO
IPC: H04N5/341
Filed: 1992-10-01
Abstract: PURPOSE:To prevent a signal charge from being left unextracted by varying a voltage applied to a gate electrode placed above a storage area receiving the injection of the signal charge from a vertical transfer section. CONSTITUTION:Four-phase vertical transfer pulses V1-V4 are applied to a gate electrode 13 of a vertical transfer section 3 and two phase horizontal transfer pulses H1, H2 are applied to a gate electrode 14 of a horizontal transfer section 4. In this case, the clocking that switches H/L levels of the horizontal transfer pulse H1 repetitively is implemented for times t6-t8. Thus, since the potential of the storage area under the gate electrode 14 receiving the horizontal transfer pulse H1 is moved vertically, the residual charge left unextracted at a tip-most part of the vertical transfer section 3 is all injected to the storage region and the signal charge in the vertical transfer section 3 is completely injected to the horizontal transfer section 4 at a time t7 just before the end of the vertical transfer period TV.

Filed: 1987-10-20
Abstract: PURPOSE:To reduce a transmission impact generated due to excessive change of increase in driving speed and driving torque by controlling the driving means of a transmission means with a control means so that the product from multiplying the driving speed by the driving torque should be under the specified value. CONSTITUTION:An operating means 6 computes a target transmission ratio using the information concerning a car speed, a throttle opening, etc., and a control means 7 determines a driving speed (a) and a driving torque DNG of a driving means 8. According to the result, the driving means 8 controls the transmission ratio of a continuously variable transmission gear 2 via a transmission means 9. Said control means 7 presets the product from multiplying the driving speed A by the driving torque B. When the product from multiplying the determined driving speed (a) and driving torque DNG exceeds the product from AXB, the control means 7 controls and redetermines new driving speed and torque to give the relation of DNC=A.B/a. Thus, a transmission impact and uncomfortable feeling of a passenger can be reduced and finally, the current transmission ratio controlled to the proper transmission ratio.

Title: Production of easily thermally decomposable polypropylene
Inventor: YOSHII FUMIO
IPC: C08L23/16
Filed: 1995-10-12
Abstract: PROBLEM TO BE SOLVED: To thermally decompose polypropylene at a lower temp. and recover the resultant oil efficiently by exposing polypropylene contg. zeolite dispersed therein to a radiation. SOLUTION: An easily thermally decomposable polypropylene is produced by exposing polypropylene contg. zeolite dispersed therein to a radiation. Any polypropylene having a number-average mol.wt. of 1.0×104 or higher may be used. The mol.wt. of 9.0×10<3> or lower gives a molding with lower physical properties and is not pref. The effect in accelerating the thermal decomposition depends on at which step zeolite is brought into contact with polypropylene; when the irradiation and thermal decomposition are conducted after mixing zeolite into polypropylene, the decomposition temp. becomes the lowest and zeolite acts effectively. The lowering in the decomposition temp., occurring at a radiation dose of 30kGy or higher, is marked when the radiation dose is high.

Title: Sampling pulse generation circuit
Inventor: SEKINE KATSUYOSHI
IPC: H03M1/12
Filed: 1991-10-14
Abstract: PURPOSE:To generate a sampling pulse having a short period by shifting next period predicted data rightward by a prescribed number of stages. CONSTITUTION:When, for example, the number (b) of shifting stages is '1', a down shift circuit 26 shifts predicted data Tnx inputted from a next period prediction circuit 24 rightward and gives the data to a pulse generating counter 25 after dividing the voltage of the data into halves. The counter 25 starts down-counting from a preset value by presetting data Tnx/2 and inputting a sampling pulse generating clock having a period of tcko/a. The counted output of the counter 25 gradually decreases and, when the output reaches '0', the counter generates a borrow signal. Upon outputting the borrow signal, the counter 25 presets the next data Tnx/2 and again starts the down-counting. When the counted output of the counter 25 reaches '0', the counter 25 again outputs the borrow signal. Thereafter, the same operation is repeated and the continuation of the borrow outputs becomes a sampling pulse output. Therefore, as the preset value is made smaller by increasing the number (b) of shifting stages of the circuit 26, sampling pulses having shorter periods can be obtained.
