Title: Manufacture of semiconductor device
Inventor: TANAKA KAZUO
IPC: H01L21/3065
Filed: 1986-11-25
Abstract: PURPOSE:To contrive to secure the reliability and stability of a wiring by a method wherein the thickness of a resist pattern is changed by using impurity- containing polycrystalline Si and polycrystalline Si not containing impurities. CONSTITUTION:In case phosphorus-containing polycrystalline Si of a line width of 1.5 mum, for example, hold a phosphorus-containing region, etching is performed with a dry etcher and assuming that the conditions are, for example, SF6CCIF3=75CC/125CC, 150W and 0.3Torr, the etching rate in phosphorus-doped polycrystalline Si 105 is 5000Angstrom /minute and the etching rate in polycrystalline Si 104 not containing phosphorus is 4000Angstrom /minute. Accordingly, during the time the polycrystalline Si 104 not containing phosphorus are completely etched, the phosphorus-containing polycrystalline Si 105 become thinner by 0.2mum at both ends for side-etching compared to the polycrystalline Si 104 not containing phosphorus. Therefore, the size 101 of a mask consisting of the phosphorus- containing polycrystalline Si 105 is made thickner by 0.2mum than that of a mask consisting of the polycrystalline Si 104 not containing phosphorus. Hereby, the line widths after the etching can be made the same.

IPC: H04L29/08
Filed: 1989-10-27
Abstract: PURPOSE:To save the cost while improving the passing rate at every communication opposite destination by setting a pre-emphasis condition based on history information of the pre-emphasis condition. CONSTITUTION:A facsimile equipment 1 registers its transmission history information to a transmission history information table of a transmission history storage section 2a for every transmission. A transmission condition estimate section 2b sets a pre-emphasis condition based on a transmission history information table of the transmission history storage section 2a at every communication and revises each items of the transmission history information table at its communication based on the result of communication. Then a pre-emphasis condition of a pre-emphasis section 3b is set based on the transmission history information of the transmission history information table and a transmission signal is subject to pre-emphasis and the resulting signal is sent. Thus, the pre-emphasis condition is set to a proper value without manual intervention and the communication rate at every communication destination is improved, then the cost is saved.

The jig 1 passes through a passing part 12, when the laser light L is intercepted by a golf ball 2, the receiving amount of the laser light is decreased. When the golf ball 2 is placed in a normal condition, the light receiving amount is D when the uppermost end U of the ball intercepts the laser light L, and when the golf ball is in an improper condition, the uppermost end U of the ball is placed in a high position, so that the light receiving amount is decreased to D' smaller than D. Then a discrimination reference preset value T is set and, the ball condition is assumed normal, when the light receiving amount is larger than this present value T, while abnormal when the light receiving amount is smaller than the preset value T, thus improper positioning can be discriminated.

Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To simplify manufacturing by boring a through hole to a plate-like member and cutting a channel plate from the plate-like member all at once. SOLUTION: One face 52A of a glass plate 52 is powder beam processed with a second resist layer 54 used as a mask, thereby forming a plurality of through holes 52E which become through hole-shaped ink channel parts of a channel plate 41 and a plurality of second through holes 52F which become positioning pin insertion holes.

As a result, every one sheet of the channel plate 41 is separately formed corresponding to each ink channel 52D like a recessed part of the glass plate 52. Subsequently, the glass plate 52 is cleaned in a state where the glass plate is attached to a substrate 50, thereby removing the resist layer 54 from on the one face 52A.  A heat release sheet 51 is heated to foam the side of one face 51A, and then each channel plate 41 is released separately from the sheet 51.

Title: Range hood
Inventor: SHIBATA HIDETOSHI
IPC: F24F7/06
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To operate a range hood efficiently regardless of the extent of enclosure of a room by employing a blade for supplying and discharging the air simultaneously in a fan. SOLUTION: A fan 2 is provided, on the back thereof, with a blade 9 for discharging the air and a blade 10 for supplying the air. When a switch is turned on to turn the fan 2, the blade 9 for discharging the air absorbs soot produced during cooking and discharges the soot outdoors through a grease filter 4. At the same time, the blade 10 turns to suck the air 15 from the outdoors. The air flow 16 passes through a duct 17 and flows downward along a front frieze board 3 from the exhaust hole 11 thereof before passing through a nozzle 12. The suction flow of soot 13 produced during cooking and deviated from a range hood 1 is entrained by the air flow 16 and introduced into the range hood 1. Since air supply and discharge are performed forcibly by the blade of the fan, high efficiency can be sustained constantly regardless of the extent of enclosure of the room.
