Title: Magnetic tape device
Inventor: ISHII TOSHIO
IPC: G11B15/44
Filed: 1987-05-08
Abstract: PURPOSE:To shorten a mode switching time by providing the control circuit setting a play mode immediately by the signal showing the reverse rotation in a tape traveling direction. CONSTITUTION:When a play switch 30 is subjected to an ON operation during a quick feeding mode, a brake control signal is transmitted from a microcomputer 34, reel motors 3, 4 are energized so as to rewind a tape 5 and the tape 5 starts its traveling in re-winding direction from forward direction. When a direction detector 39 detects the traveling in reverse direction, the signal showing the reverse direction traveling is transmitted to the microcomputer 34, which stops the transmission of a brake control signal in response to the signal showing the reverse direction traveling and outputs a play control signal instead. As a result, play mode setting transistors 19, 26 are turned ON and a constant speed traveling is started.

IPC: A61K8/68
Filed: 1988-05-11
Abstract: PURPOSE:To obtain a cosmetic having improving effects on senile xeroderma and excellent feeling in use in wetting properties, flexibility, elasticity, luster, etc., containing sphingolipid of egg yolk. CONSTITUTION:A cosmetic containing 1-6wt.% (in the case of 98% purity) sphingolipid of egg yolk.

Title: Mri device and mr imaging method
Inventor: MIYAZAKI MITSUE
IPC: A61B5/055
Filed: 1999-04-20
Abstract: PROBLEM TO BE SOLVED: To obtain an MRA image in a non-invasive manner without administering contrast media and shorten photographing time greatly by providing a scan means for imaging executing pulse sequence for three-dimensional scan in synchronization with a signal indicating a cardiac time phase per every slice encode. SOLUTION: When a sequencer receives a command for starting image scan, it starts reading of an ECG signal and judges the predetermined n-th appearance of a peak value of R wave in the ECG signal from an ECG trigger signal synchronized with the peak value. When the predetermined n-th R wave appears, the sequencer performs the processing for waiting for a set delay time TDL. This delay time TDL is optimized to a value excelling in a draw function of its entity by increasing the intensity of an echo signal to the most when a blood stream and tissue are photographed by a scan for preparation. The sequencer executes image scan using a time when the optimum delay time TDL elapses as the optimum electrocardiographic synchronization timing.

Title: Temperature controlling system of heat-sensitive recorder
Inventor: INOUE TAKASHI
IPC: H04N1/40
Filed: 1981-07-20
Abstract: PURPOSE:To ensure an accurate control of temperature and to obtain a print pattern of a certain level of concentration, by driving a heating resistance element of a heat-sensitive recorder with a constant current, monitoring the voltage drop of the heating resistance element and then cutting off the driving current at a time point when the voltage drop reaches a certain level. CONSTITUTION:A drive input signal S1 actuates a constant current driving circuit 2 through a gate circuit 1 in the case of a driving input that indicates the recording of a dot pattern provided in accordance with the heating resistance elements Rh1-Rhn of a heat-sensitive head 3. Then the corresponding elements Rh1-Rhn are selected and driven by a constant current. Here the temperature change of the heating resistance element is detected from the change of the voltage drop which is caused by the fluctuation of the resistance value. When this voltage change reaches a certain level, the electric conduction is stopped to the elements Rh1-Rhn. Thus the temperature is controlled at a prescribed level.

Title: Device for replenishing photosensitive material processing device with replenishing liquid
Inventor: KANEKO MASATOSHI
IPC: G03D3/06
Filed: 1993-05-14
Abstract: PURPOSE:To decrease the degree of deterioration of a processing liquid. CONSTITUTION:A nonprocessable state timer is started when an automatic developing machine changes from a processable state to a nonprocessable state (step 208). The inside of a developing tank is replenished with the replenishing liquid of the prescribed amt. Xn corresponding to the evaporation rate of the developer from the developing tank at every time when this nonprocessable state timer times out (step 212). The nonprocessable state timer is then restarted (step 216). The inside of the developing tank is eventually replenished with the replenishing liquid of the amt. corresponding to the evaporation quantity of the developer at every prescribed time and, therefore, the developer in the developing tank is maintained in the state of coming into contact with the rear surface of a cap part disposed in the developing tank. Since the contact area of the developer and air is small in this state, the degree of the deterioration of the developer by oxidation with lapse of time is lowered.

Abstract: PURPOSE:To save recording paper and its communication time by using 1st and 2nd recording means so as to record a picture data on both sides of the recording paper simultaneously. CONSTITUTION:A received picture data of odd numbered pages is stored in a RAM as a picture memory. When even numbered pages are received, at first the picture data of odd numbered pages are recorded on a front side 8a of recording paper 8 by 1st recording means 2, and the picture data of even pages is recorded on a rear side 8b of the recording paper 8 by 2nd recording means 5 in a timing when the recording paper 8 passes the 2nd recording means 5 simultaneously. Thus, picture information for two pages is simultaneously recorded on the front and rear sides 8a, 8b of the recording paper 8. Thus, the storage time per page is reduced more than the case when the picture data is recorded by one page in the unit of lines and the total communication time is reduced.

Abstract: PROBLEM TO BE SOLVED: To facilitate attachment/detachment of a battery pack to a main body by using a holding means for time battery pack and a detaching-direction movement suppression means even in such a state as mounting an expanded function part on the main body bottom part. SOLUTION: When an operator pushes lock members 71, 72 in the directions shown by arrows 7a, 7b, the members 71, 72 move along upper side guides 1a, 1b of the main body 1 and the lower guide, which is not illustrated, so as to release the lock. Then, when a battery pack 51 is pulled in the direction shown by an arrow 51a, the pack 51 moves along the guide 1e so that engagement of the battery connector is released so as to perform attachment/ detachment. The battery pack 52 in the expansion machine 4 side can be detached in the similar procedure. In this way, when the expansion machine 4 is in a state united with the main body 1, the battery packs 51, 52 can be easily attached/detached.

Abstract: PURPOSE:To facilitate data input operation, by displaying input data on a display device and storing the input data from a display memory to a data memory automatically before next data is inputted. CONSTITUTION:The input data is set in the display memory 10 and its contents are displayed on the display device 5. An input data end detecting part 12 counts the number of digits of the input data to detect its end. At this time, an operator confirms its contents over a look at the display device 5 and then inputs the next data. Then, a memory transfer control part 11 reads the former input data out of the display memory 10 before the next input data is transmitted and transfers it to the data memory 6. Thus, the input data is stored in the data memory 6 automatically after it is confirmed by the operator.
