Title: Method and apparatus for calibration of photometric part
Inventor: SHIBATA ISAO
IPC: G03B7/00
Filed: 1978-06-30
Abstract: PURPOSE: To obtain a light receiving device capable of making fine adjustment easily, by adjusting the quantity of incident light entering the photo detector by turning the balde member provided on the substrate in a camera.  
     CONSTITUTION: A blade member 4 is rotatably supported on a substrate 3 in a position to be secured to a photo detector 1 at one end and to run across a through- hole 3a at the other end, and a filter 5 is positioned between the detector 1 inserted into the casing of a member 2 and an opening 4a in the blade 4. When fine adjustment is necessary after an automatic exposure device is built in a camera, a proper adjusting element 6 is inserted into the oval through-hole 3a from the back side of the substrate 3, and a force parallel to the blade plane is applied to the end part side edge facing the through-hole 3a in the blade member 4. By turning the blade member 4, the area of the opposing plane on the photo detector 1 of the blade opening 4a is varied to adjust the quantity of incident light, so that a desired calibration value may be obtained.

Title: Case with sound insulation structure
Inventor: SATOU TOSHIMITSU
IPC: F16M1/00
Filed: 1980-06-16
Abstract: PURPOSE: To prevent separation of the outside wall of a crank case etc. of a motor cycle owing to deterioration of the elastic member to support said outside wall by employing a method of pressure fitting of a rigid member as a whole for fixing the wall to the case.  
     CONSTITUTION: On the whole edge 17 around the outside wall 12, is fitted the outside wall edge housing groove 21 which is formed on the inner surface of a rubber member 18. Then, this outside wall 12 with rubber member 18 is fitted by pushing in from inside a ring-shaped retainer 16 (from the edge part where no flange is  formed) until it touches the flange 19 while giving elastic deformation to the rubber  member 18. The ring-shaped retainer 16 thus fitted on the outside wall 12 is pressure-fitted in a concave 15 provided in the receptacle 13 of the crank case 10. According to this process, there is no falling off risk of the outside wall owing to deterioration of the eleastic member or exfoliation of adhesives, and thus the wall will be  secured to the case certainly for a long period.

IPC: B41J2/055
Filed: 1999-03-24
Abstract: PROBLEM TO BE SOLVED: To simply control a discharge characteristic of ink drops such as a discharge weight or the like more variously in an ink jet head of a system wherein a voltage is impressed between a diaphragm arranged via a gap for forming an ink chamber bottom face and an opposite wall, thereby deflecting the diaphragm towards the opposite wall by a Coulomb's force to discharge ink drops. SOLUTION: A bottom wall of an ink chamber 5 of an ink jet head 1 functions as a diaphragm 51, and an opposite wall 91 is set to a position where the diaphragm is pressed in contact with the opposite wall when elastically deformed. An electrode 10 opposite to the diaphragm 51 is divided to a plurality of electrode parts. The electrode parts are mutually connected by resistors, and therefore the electrode parts have different time constants. A contact state between each part of the diaphragm 51 and each surface of the opposite wall can be changed by controlling a voltage waveform of opposite electrodes, and a discharge characteristic such as a discharge weight or the like of ink drops can be variously changed.

Filed: 1994-04-19
Abstract: PURPOSE:To improve the cleaning function of ink sticking to the tip of a cleaning member by ensuring that the ink sticking to the cleaning member can be absorbed into an ink absorbent efficiently. CONSTITUTION:An ink absorbent 15 is provided on the cleaning blade 13 of a recording head and its opposite side, and the lower surface of the ink absorbent 15 serves as an ink recovery face 15a.

Title: Snooze alarm watch
Inventor: AOKI HIROSHI
IPC: G04G13/02
Filed: 1984-04-20
Abstract: PURPOSE:To enable snoozing even if an alarm switch goes out of order by storing the operation of the alarm switch by a storage circuit and resetting the same when an alarm stop switch is operated. CONSTITUTION:A flip-flop circuit 7 is set and the close of the alarm switch 1 is stored when the switch 1 is closed. On the other hand, flip-flop circuits 8, 9 and counters 4, 5 are reset and a gate circuit 12 is opened then the alarm sound is emitted by an alarm device 6. The alarm sound stops when the alarm stop switch 2 is closed just for short time of <4 seconds but the counter 4 is reset again and clocking of the snooze time starts. The alarm sound is emitted again upon lapse of 5 minutes. The above-mentioned operation is made at every closing of the switch 2 in the above-mentioned way and therefore snoozing is made possible regardless of the operating time of the switch 1.

Abstract: PURPOSE:To provide a less-expensive apparatus for detecting dangerous movement of ship or offshore structure  from anchorage position, wherein the distance of movement of the ship or the offshore structure from the anchorage position is measured by means of ultrsonic wave transmitter and receiver using the anchorage position as the reference position, and an alarm is generated when the amount of movement exceeds a predetermined  warning value. CONSTITUTION:A ship or an offshore structure (referred to as ''ship'') is provided at its portion B with an ultrasonic transmitter/receiver unit 1 directed in either the fore (bow) or aft. (stern) of the shop and another ultrasonic transmitter/receiver 2 directed to the left or right direction. The ship is provided also at its portion C with a still another ultrasonic transmitter/receiver unit which is directed either in the left or right direction perpendicular to the longitudinal axis of the hull. All of the ultrasonic transmitter/receiver units 1.2 and 3 are adapted  to transmit and receive ultrasonic waves to and from the sea bottom at predetermined angles. The signal transmitted from and received by the ultrasonic transmitter/receiver units 1, 2 and 3 are delivered to a Dopper sonic  wave velocity meters 4-6 which are adapted to measure the velocities of the ship making use of frequency  change due to Doppler effect. The velocities thus measured are integrated by integration units 7-9 into the distance of movement in each direction. The distances of movements in three directions thus obtained are  compared with respective set values in a comparator 11. An alarm is generated automatically when one of the  set values is exceeded by the measured distance of movement. It is thus possible to obtain an apparatus at a low cost.
