Title: Drip-proof, waterproof camera and waterproof structures of lid
Inventor: HAYAKAWA MASAHIRO
IPC: G03B17/08
Filed: 1994-05-24
Abstract: PURPOSE:To reduce the elastic force of a sealing member and to prevent water droplets from entering a watertight area by forming an annular sealing surface into a tapered surface whose diameter increases outwards from its axis. CONSTITUTION:An annular sealing member 20 makes elastic contact with an annular sealing surface 30 with a back lid 17 being closed and so produces a watertight state between a body 11 and the back lid 17. Then a projecting portion 21 makes elastic contact with the annular sealing surface 30 formed as a tapered surface and is therefore curved and deformed toward the outside of the body 11 along the inclination of the annular sealing surface 30. Therefore, the force with which the annular sealing member 20 makes elastic contact with the annular sealing surface 30 is reduced. When the back lid 17 is open, water droplets are made to flow outside of the body 11 along the inclination of the annular sealing surface 30 by gravity and are therefore not allowed into the body 11. Thus the force with which the annular sealing member 20 makes elastic contact with the annular sealing surface 30 is reduced, and water droplets attached to the annular sealing surface 30 when the lid is opened can be prevented from entering a watertight area.

Title: Buttonhole sewing machine
Inventor: HIRANO YASUAKI
IPC: D05B3/06
Filed: 1999-04-19
Abstract: PROBLEM TO BE SOLVED: To suppress the generation of abrasion powder on a slide surface and prevent the stain of a material to be sewn by providing a resin with a self-lubricating ability between the lower surface of a cloth feed plate and the slide surface in a buttonhole sewing machine for forming seams in a position in which the buttonhole for the material to be sewn is formed. SOLUTION: When a sewing machine is driven, a feed driving shaft 19 rotates counterclockwise little by little synchronously with the formation of seams to move a cloth feed shaft 1 rightward and leftward. With the movement of the cloth feed shaft 1, the lower surface of a cloth feed plate 16 moves rightward and leftward under the pressed state of a bearing member owing to the resilient action of a presser spring 12. Thus, buttonhole sewing seams are formed on a cloth. In this case, the upper surface of the bearing member for bearing the lower surface of the cloth feed plate 16 is made of a resin with a self- lubricating ability small in its friction coefficient. Both the side end faces of the cloth feed plate 16 are guided by a guide plate made of a resin with the self-lubricating ability small in its friction coefficient.  Thus, the generation of abrasion powder on a slide surface is prevented.

Title: Lamp starter
Inventor: OOTANI KATSUYA
IPC: H01J61/56
Filed: 1983-06-20
Abstract: PURPOSE:To obtain a starter having simple structure economically by employing a bimetal of self-heating operation type. CONSTITUTION:A bimetal 8 is made of such material as having high resistivity and upon power supply, the bimetal itself is heated to start function. Upon application of source power across A-A' at first, voltage is applied across a choke 5, glow lamp 2, and a bimetal switch 8 to start discharging of the glow lamp 2. Consequently the glow lamp 2 is shortcircuited to produce high voltage immediately upon separation to start function of a light emission tube 1. If it has failed starting, the glow lamp 2 is under shortcircuited state where current will flow continuously through the bimetal 8 to rise the temperature and perform bimetallic function thus to interrupt the circuit 2-8. The light emission tube 1 is started through the interruption effect.

Abstract: PURPOSE:To quicken a fall of an ATD signal, and to prevent a delay of a CS access against an address access by providing an ATD circuit for generating a one shot CS pulse signal by a variation of a CS input signal, and controlling a pulse width by its signal. CONSTITUTION:When an address signal is varied, an output of an input buffer 1 is varied, and an ATD circuit 3a generates a one shot pulse, but in case when an inversion CSext is not varied, an inversion CST becomes H, and the circuit 3a generates a pulse ATSi of an RDI or FDI width. When the inversion CSext is varied to L from H, the inversion CST is generated by a one shot CS pulse generating circuit CSTD 8, and the circuit 3a generates the pulse ATSi of an RD 2 or FD 2 width. Accordingly, a width of an output ATD signal of an OR circuit 4 becomes small, as well, a fall of its signal is quickened, a delay by a CS buffer of an access time of the time when the inversion CSext has been varied is compensated, and a CS access time being equal to an address access is obtained.

Abstract: PURPOSE:To improve address extension properties by providing a storing means for address space information to the address response control so that the address of an access object circuit can be easily set and added. CONSTITUTION:A storing means 6 receives and stores previously the address space information on an access object circuit 2 from a processor 1.

Then a deciding means 7 compares the address space information on the circuit 2 stored in the means 6 with the address given from the bus 3. Then the means 7 outputs an address response command 29 to an output means 8 as long as the address sent from the bus 3 is included in the address space of the circuit 2. The means 8 outputs an address response signal 9 to the processor 1 by the command 29 and the processor 1 performs the exchange of data to the circuit 2.
