Title: Semiconductor device
Inventor: HAYASHI TETSUYA
IPC: H01L29/78
Filed: 2008-09-30
Abstract: <P>PROBLEM TO BE SOLVED: To provide a semiconductor device that can uniformly pass current through the end of a heterojunction interface in contact with a gate insulating film, exhibiting high cutoff performance.  <P>SOLUTION: In the semiconductor device, a hetero semiconductor corner region 10, which is a current-concentration relief region that prevents a reverse bias current from concentrating at the convex corner, is arranged in a hetero semiconductor region 3. Thereby, a current concentration at the convex corner can be prevented. As a result, an cutoff performance can be improved at the time of cutoff, and at the same time, generation of any hot spot at a specific portion is prevented at the time of conduction to suppress deterioration in a specific portion, thus ensuring a long-term reliability. Further, when a semiconductor chip 100 is used in an L load circuit or the like, for example at the time of conduction or during a transient response time to the cutoff state, even as for an index such as a short-circuit resistance amount and an avalanche resistance amount, which are indexes of a breakdown resistance when overcurrent or overvoltage occurs, the current concentration on a specific portion can be prevented, and thus these breakdown resistance can be also improved.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Title: Cover for vehicle
Inventor: KUWAHARA SHINJI
IPC: B62J19/00
Filed: 2008-10-01
Abstract: <P>PROBLEM TO BE SOLVED: To provide a cover for a vehicle that can smoothly be removed from the vehicle.  <P>SOLUTION: The cover includes four sheets, a front surface sheet 1, a upper surface sheet 2, a left side surface sheet 3, and a right side surface sheet 4, each of these sheets being sewn up to constitute the cover. Each of the front surface sheet 1 and the upper surface sheet 2 has a tongue 9 extending toward the counterpart, the sheets being lined up side by side. The size of the tongue 9 formed on the front surface sheet 1 is larger than that formed on the upper surface sheet 2, and when the outer edges of both the tongues 9, 9 are sewn up, a uprising portion 6 of the edges can be raised and tilted toward the side of the upper surface sheet 2. Because this uprising portion 6 is formed to rise from the vehicle body, a tab for grabbing is larger, and therefore the cover can be smoothly removed.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Title: Fiber optic link, transceiver for use in fiber optic link, and method for designing and constructing fiber optic link and transceiver
Inventor: CUNNINGHAM DAVID GEORGE
IPC: H04B10/43
Filed: 2008-10-16
Abstract: <P>PROBLEM TO BE SOLVED: To achieve a fiber optic link which operates at high data rate inexpensively.  <P>SOLUTION: If a laser meets certain requirements for noise, a data rate of a transceiver can be greater than the data rate of the laser. In particular, a relative intensity noise (RIN) of the laser must be low enough to ensure a low bit error rate (BER) of the link. Relatively inexpensive low bandwidth optical and electrical components that meet such condition are incorporated and an electrical equalization is performed.  <P>COPYRIGHT: (C)2009,JPO&INPIT

Title: Air reformer, reformed air supply device, and combustion rate improving air supply machine
Inventor: AKAIKE MASUMI
IPC: F23L7/00
Filed: 2008-10-20
Abstract: <P>PROBLEM TO BE SOLVED: To provide an air reformer manufactured at low cost by simple structure.  <P>SOLUTION: In this air reformer 1, since an air reforming section 3 is provided with a sheet body 32 with an air reforming agent deposited on at least one side, and arranged in a cylindrical body 31, air passed through the inside of the cylindrical body 31 is reformed by being brought into contact with the air reforming agent deposited on the sheet body 32. When a connection section 2 having an air flow passage communicating with the air reforming section 3 is connected to a combustion device, reformed air is fed. Therefore, the combustion efficiency of the combustion device is improved, and saving in fuel and reduction in the total exhaust gas and carbon dioxide are achieved. Besides, since the air reforming agent is only deposited on the sheet body 32 and arranged in the cylindrical body 31, the air reformer has the extremely simple structure and manufactured at low cost.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Title: Bar code reader
Inventor: MASUKO TOMOMI
IPC: G06K7/10
Filed: 2008-10-23
Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem of a small bar code reader for reading information with a laser beam scanned by rocking a scanning mirror wherein the rocking width is difficult to be always kept constant due to the influence of an external environment, and the scanning mirror collides with an adjacent component to cause an abnormal noise and affect the scanning of the scanning mirror.  <P>SOLUTION: When the scanning mirror collides with an adjacent component, this bar code reader temporarily stops application of a drive signal or reduces and applies the drive signal to be applied, narrows the rocking angle (scan width of laser beam) of the scanning mirror to eliminate the collision, then gradually and linearly increases and adjusts a normal-time drive signal in a stroke, and returns to a normal rocking state in a short time.  <P>COPYRIGHT: (C)2010,JPO&INPIT
