Title: Key driving device for keyboard instrument
Inventor: MURAMATSU SHIGERU
IPC: G10F1/02
Filed: 1990-05-29
Abstract: PURPOSE:To prevent a decline in energy efficiency caused by magnetic leakage and heat production by providing an inclined piece to an upper yoke and a lower yoke provided with an inclined side piece and electric heating member to an electromagnetic force generating means. CONSTITUTION:Since an upper yoke 34 is provided with inclined pieces 34a at both end sections, the yoke 34 can be faced to a lower yoke 35 so as to cover the entire surface of the yoke 35. Accordingly, a large facing magnetic gap area can be secured between both yokes 34 and 35. Because of both inclined pieces 34a and both inclined side pieces 35a, in addition, the initial attracting force is increased and attracting forces in the length direction of a key 31 are offset by each other. Moreover, heat is radiated from an electric heating member 37 positioned in a space provided between the inclined side pieces 35a of the lower yoke 35. Therefore, magnetic leakage can be suppressed and the energy efficiency can be improved. At the same time, overheating of a coil 36 can be prevented.

Title: Optical space transmitter
Inventor: HOSONO KOJI
IPC: H04B10/564
Filed: 1995-06-06
Abstract: PURPOSE: To attain stable data communication regardless of fluctuation in a transmission efficiency of an optical signal by controlling an optical signal output level in response to a reception level of an optical signal from an opposite party terminal equipment. CONSTITUTION: Prior to communication, each light receiving element 3 receives an optical signal from opposite party terminal equipment with each other, converts the signal into an electric signal and it is amplified by an amplifier 4 by a prescribed amplification factor. A reception level detection circuit 7 discriminates whether or not the signal level is within a prescribed range and gives the result to an optical output level control circuit 8. The control circuit 8 controls a drive circuit 2 based on the information to adjust an optical output level of a light emitting element 1 to be a range for stable communication by using a resistor to limit a current through the light emitting element 1 or adjusting the number of driven elements 1.  Thus, even when the transmission efficiency of the optical signal is fluctuated due to difference from a communication range or an obstacle on a communication path, stable communication is conducted. Furthermore, when a communication range is short, power is saved by using a decreased output level.

Title: Hydraulic control method for automatic transmission for vehicle
Inventor: YASUE HIDEKI
IPC: F16H61/10
Filed: 1983-07-29
Abstract: PURPOSE:To shorten time lag under kickdown while to prevent shock by increasing the speed of hydraulic pressure to be discharged from a friction engaging system in accordance with the increase of engine load. CONSTITUTION:An orifice control valve 9 to be controlled by the throttle oil pressure Pt from a throttle control valve 8 is provided in the discharge path of clutches 1, 2 and brake 3 to increase the speed of oil pressure to be discharged from the clutches 1, 2 and the brake 3 as the engine load increases. Since the oil pressure discharge speed from the brake 3 is increased under kickdown when compared with partial down, the time lag of kickdown is shortened. Since the clutch 2 will never engage until the engine rotation will reach to the synchronous rotation of oneway clutch, shock is prevented.

Title: Audio device
Inventor: HONDA KANJI
IPC: G11B19/02
Filed: 1993-05-19
Abstract: PURPOSE:To play a target recording medium even though the storage location of the medium is changed by collating detected position information and registered position information every time the recording medium is played and updating a program list when the two information are unmatching. CONSTITUTION:When a playing key is pushed, a CPU 4 sends a playing command of a target disk to a CD changer 3. The identification and position information detected by the changer 3 are stored in a RAM 8. When the track of the disk related to the playing is registered in a program list, the detected identification and position information are collated against the registered identification and position information. When they are unmatching, the detected position information is newly resistered in lieu of the registered position information which is registered in the program list and the list is updated. Thus, the target disk is played even though the storage location of the recording medium is changed.

Title: Method for controlling thickness of electroless plating film
Inventor: YOSHIZAWA IZURU
IPC: G01B13/06
Filed: 1990-05-28
Abstract: PURPOSE:To control the thickness of an electroless plating film at a relatively low cost and with sufficient precision by detecting the progress of plating from a change in the liq. surface with a partitioned section communicating with a residual section through a metallic mesh dipped in an electroless plating soln. CONSTITUTION:A metallic mesh 3 laid over the bottom opening of a vessel 2 is dipped in an electroless plating soln. 1 to form a partitioned section A communicating with a residual section B only through the mesh 3. The plating soln. 1 in the residual section B is then introduced by a feed pump 4 into the vessel 2 from its upper opening, and the plating soln. 1 is circulated between the sections A and B through the mesh 3. As electroless plating proceeds, the liq. surface 21 of the section A is raised due to the clogging of the mesh 3. The clogging of the mesh 3 accurately corresponds to the thickness of a plating film on a body to be electroless-plated. Accordingly, the ascension of the liq. surface 21 is measured to detect the progress of plating, and the thickness of the plating film is controlled.

Accordingly, the recording paper will not cause the ink outlet to be clogged with paper powder, since the recording paper is perfectly cleanced before reaching opposite the recording head 108.

Title: Stacked type heat exchanger
Inventor: IZUNAGA YASUSHI
IPC: F28D9/00
Filed: 1982-08-13
Abstract: PURPOSE:To obtain the stacked type heat exchanger having a large heat exchanging capacity by a method wherein the flow speeds of both heat exchanging liquids are increased and both of the liquids are flowed opposingly along the whole of the flowing paths thereof. CONSTITUTION:The blade-tube side liquid enters from an inlet pipeline 4 and the stream thereof is branched before entering into the layer-type flowing paths 8. The flow directions of the liquids in each layer-type flow paths are turned twice by bulkheads 12, 13, thereafter, are joined together to discharge them through an outlet pipeline 5. On the other hand, cylinder side liquid enters from the inlet pipeline 6 into the layer-type flow path 9, exchanges the heat thereof with tube plate side liquid while turning the flow direction twice by the bulkheads 14, 15 in the manner of the opposing flow, thereafter, it is joined together and is discharged from the outlet pipeline 7. In this case, the flow speed of both liquids becomes substantially three times as compared with the conventional stacked type heat exchanger and, therefore, a large heat exchanging capacity may be obtained. In case of a single phase flowing, for example, the heat transfer rate is made proportional to the flow speed to the power of 0.8 generally in case of a turbulent flow, therefore, the heat transfer rate of about 2.4 times of the conventional stacking type heat exchanger may be obtained in both liquids. Further, a large temperature efficiency may be obtained because all heat exchanging flow paths are formed into meandering flow paths of counter-flow type.
