Title: Radio communication method and radio communication system
Inventor: OHASHI TSUTOMU
IPC: H04W74/08
Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To provide the radio communication method and the radio communication system by which re-transmission of data packets is properly attained even on occurrence of the data packets collision and stable data transmission/reception are conducted under simple control in the case of data transmission/reception by a half duplex system between a master station and a slave station. SOLUTION: When a master station receives a transmission request on the radio communication system, the master station generates a data packet to be sent to a slave station (step S1), confirms that the master station receives no data at present (step S2), and transmits the data packet to the slave station (step S3). When the master station does not receive response packet with respect to the data packet (step 4; NO), the master station transmits again the data packet previously sent (step S6) after awaiting the lapse of a re-transmission waiting time (step S5), and the master station repeats the processing in the steps S4 through S6.  Since the re-transmission waiting time is set longer than a re-transmission waiting time of the slave station by twice of a radio delay time and a time width of the data packet, the re-transmission processing of the data packet of the slave station is conducted with priority and then data transmission/reception are stably conducted even on occurrence of data collision.

Title: Thermal head
Inventor: NAMIKI KOJI
IPC: B41J2/335
Filed: 1987-09-30
Abstract: PURPOSE:To decrease a heat conductivity to enhance an energy efficiency and to improve a resistance to foreign particles and a life, by making a heat resistant layer of a porous glass impregnated with a heat resistant resin. CONSTITUTION:For example, on an alumina substrate 1, a heat resistant layer 2 is formed by infiltrating a heat resistant resin in a porous glass mainly composed of a borosilicate soda glass etc. Thereon, a heating resistor layer 3, a lead layer 4, and a protective layer 5 are successively formed. The heat resistant layer 2 mainly composed of the borosilicate soda glass is formed on the alumina substrate 1 to be approximately 100mum thick by a normal printing and burning method, thereafter being subjected to a heat treatment so that the phase is split into a part A with a high silica concentration and a part B with a high boric soda concentration. The part B with a high boric soda concentration turns into a hollow B1 by being dipped in a hot hydrochloric acid. Then, the heat resistant resin C is infiltrated in the hollow B1 to be loaded therein, whereby the heat resistant layer 2 with a surface smoothness is formed. In this manner, in comparison with the prior art, the same color density can be obtained with a smaller applied energy. In addition, the skeleton of the porous glass imparts resistance to breakage even with foreign particles involved.

IPC: B63H20/08
Filed: 1986-10-20
Abstract: PURPOSE:To simplify while solidify the structure of a tilt device and increase the reliability on the strength of said tilt device which enables the adjustment of a tilt-down lock position by providing a cam groove for supporting a lock pin on a swivel bracket. CONSTITUTION:As a swivel bracket 15 is moved upward, a lock pin 30 is engaged with adjacent upper stage engaging groove parts 28 in order being guided by a cam groove 31, adjusting a tilt-down lock position gradually to the upper side. In this case, since the lock pin 30 is directly supported by the cam groove 31 provided on the swivel bracket 15, not via an operating lever, etc., the structure of a tilt device can be made simple and solid. Also, since the engagement between the lock pin 30 and a stopper member 34 is removed by means of an engagement adjusting member 35 after the lock pin 30 is moved to return downward after passing through the top stage engaging groove part 28, the swivel bracket 15 is automatically returned down side and the lock pin 30 is newly engaged with the engaging groove parts 28.

Title: Feeder device
Inventor: MATSUMOTO YASUTAMI
IPC: H01R41/00
Filed: 1990-09-18
Abstract: PURPOSE:To make it unnecessary to use a slip ring and miniaturize a device by providing a stopping position controlling means which stops rotation of a rotor when a rotation side contact and a fixed side contact are opposite each other in such a manner that the contacts can be connected together, and a means for advancing and retreating contacts which advances and retreats the fixed side contact so as to connect the rotation side contact and the fixed side contact together or separate the contacts from each other. CONSTITUTION:A stopping position controlling means stops rotation of a rotor 4 when a rotation side contact 22a and a fixed side contact 22b are opposite each other in such a manner that the contacts can be connected to each other. To feed electricity, the fixed side contact 22b is shifted toward the rotation side contact 22a by a means for advancing and retreating contacts and both of the contacts are connected together and when feed is completed the fixed side contact 22b is shifted and separated from the contact 22a; that is, the rotation side contact 22a and the fixed side contact 22b are connected together only during feed to equipment and are separated from each other during rotation of the rotor 4. Feed to the equipment provided integrally with the rotor 4 is thus made possible without using a slip ring and so a device can be miniaturized and also the reliability of feed is enhanced without raising the cost to a large extent.

Title: Manufacture of shallow well mosfet structure
Inventor: KOCON CHRISTOPHER
IPC: H01L29/78
Filed: 1999-09-02
Abstract: PROBLEM TO BE SOLVED: To achieve a desired channel length and to prevent reduction of a breakdown voltage that occurs too early, by defining the channel length while depositing a polysilicon spacer layer on a field insulating layer and a gate insulating layer to form an implanting mask having an overlapped thickness, and by extending a PN junction. SOLUTION: A polysilicon spacer layer 125 is unselectively deposited on a field insulating layer 111 and a gate insulating layer 121. As a result of the unselective formation of the layer 125, the surface of a shallow P well region 107 is covered by an implanting mask 130 having an overlapped thickness. This structure is implanted with a high energy impurity for a single or plural times to excessively dope a portion of the region 107 and convert such a portion into the conductivity of an N- epitaxial layer 101. This causes a PN junction to extend to the surface of the region 107 under the layer 121, thereby defining the channel length between the side end edge of the layer 111 and the extended PN junction.
