Title: Event or dialogue watch
Inventor: FUORUKERU HETSUPU
IPC: G04G99/00
Filed: 1981-03-11
Abstract: An event-module is, on its lowest logical level, a universal instrument for measurement and storage of times, intervals, periods, time series and durations. It permits codification of personal and external events by means of time-marks and makes them accessible in the course of their realization. It permits the possibility of analyzing the serial structure and the correlation in time of these events in a most general way. The evolution of the present can instantaneously be compared with the anticipation of the future by use of external time-marks. Further, the introduction of a programmable dialog-logic which enables the user to find answers to specific questions of, e.g., his personal experiences is disclosed. The module helps in decisions and is not only a measurement device, but also a partner. Likewise, the module can act as an opponent of the user and e.g. sophisticated games may be played. The event-module can be considered a cybernetic system into which the human being is incorporated in contrast to conventional learning machines (TURING machine, chess computer) and which interacts with his behavior patterns (habits, orderliness, etc.). This system not only records events and their duration and displays them on demand, but it interferes due to its boundary conditions (Te,  DELTA Te) with the actual course of events. It is a mobile, interactive system with learning potential.

Filed: 1989-02-14
Abstract: PURPOSE:To record an image fast without deteriorating the picture quality even if a main scanning line snakes by restarting main scan recording at intervals of step driving during the residual vibration generation of a recording head after the driving stop of a stepping motor and a constant time after the start of the driving. CONSTITUTION:The starting period of the main scan recording on a photosensitive material is set in the residual vibration generation of the exposure head by the stepping motor 76 and the constant time after the driving start of the stepping motor 76. Therefore, a main scanning line 99 which is recorded snakes owing to the residual vibration caused after the driving stop of the stepping motor 76, but the track of the snaking becomes constant, so the picture quality never deteriorates. Further, an image recording period is set in the residual vibration generation and the speediness of the image recording is not spoiled. Therefore, even if the main scanning line 99 snakes owing to the residual vibration of the stepping motor, the image can be recorded fast without deteriorating the picture quality.

Title: Paper feeding mechanism
Inventor: ASAKURA OSAMU
IPC: B41J19/78
Filed: 1983-03-04
Abstract: PURPOSE:To perform secure click operation and feed the paper with a little power consumption using a small size motor by a method wherein a worm wheel, mated with a worm gear driven by a motor, is connected to a paper feeding shaft through a detent member. CONSTITUTION:When the paper is fed automatically by a paper feeding motor 5, a wormwheel 13 is rotated by the rotation of the motor 5 through a wormgear 12. Although the wormwheel 13 is connected to a platen shaft 2 so as to rotate freely, because a roller 17 is pushed against a detent plate 19, the wormwheel 13 is rotated with the star shape detent plate 19. Then the platen shaft 2 is rotated and a platen 10 is rotated. With this method, because a detent lever 15 is rotated solidly with the wormwheel 13 when the paper is shifted automatically, the detent lever 15 need not be pushed up. Therefore, the paper feeding motor 5 may have only small power and the power consumption is saved significantly.

Title: Resin mold semiconductor device
Inventor: TAKAO HIROSHI
IPC: H01L23/28
Filed: 1979-03-26
Abstract: PURPOSE: To prevent the upper surface of a package consisting of a mold resin  from crack generation by forming the top of the package of mold resin in circular  arc shape in section.  
     CONSTITUTION: A package 1 is obtained through molding a resin, and its top 1a is formed in circular arc in section. Rate of thermal expansion of the mold resin is generally larger than that of a mold, therefore when a product is quickly cooled down after molding is over, the top 1a contracts quickly circumferentially. The top 1a comes to release from the mold when molding is over even though it was kept sticking to the mold at the beginning of molding. Thus an occurrence of cracks on the package during mold releasing is prevented, a deterioration in moisture resistance is also prevented, and the reliability can be improved accordingly.
