Title: Draining basin
Inventor: ISAKA YOSHITAKA
IPC: E03F5/10
Filed: 1994-02-14
Abstract: PURPOSE:To prevent breakage of a draining basin by furnishing a rubber ring receptacle over a riser pipe, providing a stepped part in a back part in the receptacle, and equipping the stepped part with a plane which detains the bottom of another riser pipe as a joint. CONSTITUTION:A draining basin 1 is equipped with a rubber ring receptacle 12 over a riser pipe 11, and a ring-shaped recess 14 to admit fitting of a rubber ring 13 is formed near the top opening of the receptacle 12, and in a back part in this receptacle 12 a stepped part 15 is provided which detains the bottom of a joint riser pipe 2 by bending the pipe wall, and the stepped part 15 is furnished with a plane 16. Two pipe connecting mouths 17, 18 are provided under the riser pipe 11, and to them branch pipes 3, 4 are connected. The bottom of the joint riser pipe 2 inserted in the receptacle 12 is detained with the plane 16 on the stepped part 15 to ensure that any long-time service does not cause the joint riser pipe 2 to fall into the riser pipe 11. This precludes breakage of the basin 1 owing to falling-in of the joint riser pipe 2.

Title: Gear transmission device
Inventor: SAITO NOBUAKI
IPC: F16H55/18
Filed: 1996-02-02
Abstract: PROBLEM TO BE SOLVED: To prevent occurrence of backlash without increasing the number of parts and without enlarging a space by forming a groove which extends the whole of tooth width from a tooth top toward a center part, on each tooth of at least one of gear of two gears. SOLUTION: Slit shaped grooves 16 which extend the whole of tooth width are formed on all teeth 15 from a tooth top toward the axial core of a gear 13. The cross sectional shape of the final end part 16a of the groove 16 is formed in a circular shape having a diameter larger than the width of the groove 16. Since the gear 13 is elastically deformed when rotation is transmitted, rotation is transmitted smoothly. Since stress applied on the teeth 15 is dispersed by the final end part 16a, concentration of the stress can be prevented.

CONSTITUTION:The 2n units of photodetecting elements D1-D2n are divided into two groups every (n) units. An output terminal Q of flip-flop FF1 and FFn+1 of the first stage of each group is set at a high level respectively. While the terminal Q of each of FF2-FFn and FFn+2-FF2n is set at a low level. Then a line 32 is set at a low level, and a clock signal is extracted from a line 33. Then the terminal Q of the FF1 is set at a high level, and the line 32 is set at a low level again. Thus a logical state is attained as shown in a table. Then the line 36 is set at a high level, and the clock signal is extracted from the line 33. Thus the logical states of FF1-FF2n are shifted by a stage for each group. This attains the simultaneous scan/read is possible for each group.

Then the maximum level of the frequency component passing through the filter 106 is detected by a frequency component detector 106 and stored once in a frame memory 104. Then an optical system drive section 108 detects the maximum level of the component again and a focus evaluation discrimination 107 compares the maximum levels. If the present level is smaller than the level detected precedingly, a lens optical system 101 is moved in the opposite direction and if larger, the lens system is moved in the same direction as that in the preceding detection. Then the position where the maximum level is obtained is used as the focal point.

IPC: H04Q3/42
Filed: 1987-01-30
Abstract: PURPOSE:To attain exchange connection of a loop dial system without error independently of the line current detection characteristic of an incoming trunk circuit by preventing the momentary interruption of the line current at dial pause. CONSTITUTION:In controlling the ON/OFF of a 1st transistor (TR) 5 sending a dial pulse and the ON/OFF of a 2nd TR 6 forming a loop circuit, after the transmission of a dial pulsetrain and the 2nd Tr 6 is turned on after a time t1, a loop circuit is formed and a current starts flowing to a letter coil 8. The 1st TR 5 is turned off after the current reaches a steady-state in a time t2. Thus, when the 1st TR 5 is turned off, the current flowing to the coil 8 reaches a steady-state value, the line current I is not momentarily interrupted. Thus, momentary interruption mis-recognized as one dial pulse like a conventional control system causing erroneous exchange connection is avoided.

Title: Refuse incinerator
Inventor: SHICHIRI MASATAKA
IPC: F23G5/00
Filed: 1993-02-05
Abstract: PURPOSE:To avoid a lowering of a burning temperature due to supply of excess combustion air by so inclining right and left sidewalls of a conveying passage for throwing a matter to be incinerated to an inside as to be converged toward a secondary combustion zone. CONSTITUTION:An upper space of a stoker 5 is formed in a primary combustion zone 1 for directly incinerating a matter to be incinerated, and further its upper space is formed in a secondary combustion zone 2 for completely burning combustion gas. Right and left sidewalls of the stoker 5 are so inclined to an inside as to be converted toward a flue for forming the zone 2. Accordingly, the combustion air rising along the sidewalls inclined to the inside becomes an air flow bent to a center upon rising to vigorously collide with unburnt gas rising at the center to be agitated and mixed. Therefore, it is not necessary to particularly supply a large quantity of the combustion air to the zone 2.
