Filed: 1984-08-21
Abstract: PURPOSE:To reduce bird beaks and bird heads by applying a scratch by implanting high density ions to a region to be selectively oxidized and oxidizing at low temperature, thereby utilizing accelerating oxidation phenomenon. CONSTITUTION:A silicon oxide film 2 and a silicon nitride film 3 are sequentially formed on a silicon substrate 1, a hole 4 is formed at the film 3, and ions are implanted. The impurity 9 to be implanted is optimally argon of inert gas in the substrate 1 by applying scratch to the substrate 1 efficiently. Higher ion implanting density is effective. High pressure oxidation in steam is performed at low temperature of 900 deg.C or lower to obtain a separate oxide film 10. If performed at high temperature of 900 deg.C or higher, the scratch is annealed during the oxidation to reduce the accelerating oxidation effect. The suppressing effect of bird beak or bird head is remarkably exhibited at lower temperature of approx. 800 deg.C.

Title: Controlling method for plate thickness with tandem cold rolling mill
Inventor: HAYAMA YASUNOBU
IPC: B21B37/00
Filed: 1981-11-02
Abstract: PURPOSE:To permit high rolling reduction rolling and to control the plate thickness in the stage of gnawing with high accuracy by setting the roll gap of the 1st stand large for the beginning, and setting the same at a slightly smaller gap thereafter gnawing a rolled material into the next stand then returning the gap to the set value. CONSTITUTION:In tandem cold rolling mill, the roll gap of the 1st stand is set at DELTAS01+DELTAS1b larger than the set roll gap determined by pass schedules. Upon lapse of a time DELTAT11 after gnawing of the rolled material in the 1st stand, the gap is set at a slighly smaller gap DELTAS01-DELTASa determined by the quantity at which no tension exists. Thus the tension between the stands until the material is gnawed into the 2nd stand is corrected to zero. When the rolled material is gnawed in the 2nd stand, the roll gap is returned to the value DELTAS01 determined from the pass schedules after lapse of a time DELTAT12. Thereafter the set roll gaps of the 2nd and succeeding stands are changed in the same manner, whereby the thickness of the plate is controlled.

Minor gears 17 and 17' are set at the upper part of revolving shafts 16 and 16' and mesh the teeth 13 and 13' of the gears 4 and 4' respectively. The lower part of the gears 17 and 17' is connected to the part 10. The hands 5 and 5' interlock with each other with the transmission of revolution from the part 10. The gears 4 and 4' which are provided inside a timepiece and serve as the revolution transmitting mechanism of the hands 5 and 5' are camouflaged and cannot viewed from outside. Thus it seems as if the hands 5 and 5' attached to the plate 2 move with no motive power.

Title: Variable resistor
Inventor: MASUDA FUMITOSHI
IPC: H01C10/32
Filed: 1991-07-17
Abstract: PURPOSE:To obtain a compact variable resistor that is of simple construction and easy to assemble, and further is low in production cost by permitting a planetary disc to slip on an external tooth gear. CONSTITUTION:A planetary disc is made of the elastic material which is housed in a recessed groove 43 passing through the center of a rotor 24 that is formed on the face opposed to a rotor operating member 26, and it is brought into contact with an internal tooth gear 48 and external tooth gear 49 elastically. The rotor 24 does not stop rotating before a wiper reaches the utmost end of a resistant body and when it reaches the utmost end, the disc 47 slips on the gear 49. Thus, even when the member 26 is further rotated, a rotation transmission mechanism to transmit a rotative power of the member 26 to the rotor can be prevented from breakage and at the same time no special clutch mechanism is necessitated, resulting in simpler construction, easier assembling work, lower production cost and reduction of size.

Abstract: PROBLEM TO BE SOLVED: To revise a switching period of an illustration image in matching with preference of the user and urgency of a message by revising optionally plural illustration image changeover periods displayed on a display means. SOLUTION: A selective call signal is received by an antenna 1 and a radio section 2 and demodulated by a demodulation circuit 3 and fed to a control section 4. The control section 4 compared its own ID in an ID-ROM 5 with a selective call signal ID and when they are coincident, a call notice signal is sent to a drive circuit 6 and a call tone is sounded from a speaker 7. Simultaneously a message code is given to a display drive circuit 8, where illustration display pattern data corresponding to the code are read from a ROM 11 and the data are displayed on an LCD 9. Furthermore, an illustration display period is set in a counter 12 of the control section 4 and the setting is revised by an external SW 13. Thus, the user sets an image switching period in matching with urgency of a message or when feeling slow/fast switching period of the illustration.

Title: Image reader and white level correction method
Inventor: MATSUDA KAZUNORI
IPC: H04N5/16
Filed: 1999-06-24
Abstract: PROBLEM TO BE SOLVED: To generate a normal white level even on the occurrence of deposition of dust or dirt on a white reference by detecting a suddenly changed level that is regarded as abnormity of a white level and changing the level to a prescribed level so as to correct the white level when dust or dirt is in existence on the white reference in the case of generating the white level. SOLUTION: An image read section 101 uses a CCD or the like to read an image, a white level control section 103 reads a white reference and stores the white level of the read white reference to a white level storage section 102. On the occurrence of deposition of dust or dirt on a white reference, a white level correction section 105 detects a white level with a sudden fall that is generated by the white level control section 103 and stored in the white level storage section 102 and corrects the white level into a white level having no sudden fall. Since a shading correction section 104 reads an image on the basis of the corrected white level to correct shading of an image, the image reader can output image data without longitudinal stripes.

IPC: F23N5/24
Filed: 1994-07-06
Abstract: PURPOSE:To reduce the influence of pressure change to a gas meter without gas supply failure. CONSTITUTION:A piezoelectric film sensor 35 detects a fluidic oscillation. The output of the sensor 35 is amplified by an amplifier 71, and a pulse is generated from a digitizer 72. A timer 73 counts a predetermined time, and a counter 75 counts the pulse. When the counted value of the counter 75 does not reach a count-up value and the timer 73 counts the predetermined time, a shut-off vale is made to be in a state to reduce its pressure change by an actuator control circuit 77. When the counted value of the counter 47 reaches the count-up value before the timer 73 counts the predetermined time, the valve is switched to be in a state in which the entire opening is opened by the circuit 77 at that time point.

Abstract: PURPOSE: To make the light beam distribution uniform which covers menu columns and to correctly detect a selected menu by providing optical element arrays along the four side edges of a display board, longitudinally arranging the groups consisting of light emitting and receiving elements and making them correspond the menu columns. CONSTITUTION: When X axis optical element arrays 8A and 8B and Y axis optical element arrays 9A and 9B are provided to the side edges of outer sides 4 of a display board 1, light emitting elements 10 and light receiving elements 11 are arranged side by side, made into sets and are made to correspond to menu columns 2. On the top of the respective menu columns 2, scanning light beams 15 in parallel to the X axis are traveled. Among these beams, some of them are enlarged toward their tips in one direction of the X axis and the others are expanded in the other direction. Moreover, the two beams which are parallel to the Y axis are operated in a similar manner so that the radiated light distribution on the columns 2 is made uniform regardless of the arrangement locations.  Thus, unnecessary light beams are shielded by pressing a desired menu column with a pencil and the selected menu is correctly detected.
