Title: Brake control device for electric automobile
IPC: B60T8/58
Filed: 1992-03-27
Abstract: PURPOSE:To enable realization of suitable ABS control even at a low mu (coeffi cient of friction) road. CONSTITUTION:A regeneration brake force command value Tr is corrected by means of a brake force correction value dT at 210 in a state, when ABS control is executed, a hydraulic brake force command value Tb is held at the same value as a preceding hydraulic brake force command value Tb1. At 200, the brake force correction value dT is a negative value when a wheel lock tendency is detected, and a positive value when a wheel speed is restored. When the brake force correction value dT is high, the regeneration brake force command value Tr is a command value expressing powering torque. Since, during ABS control, torque of a motor for drive is used in a state to contain the powering torque side, a total brake force being a sum of hydraulic brake forces is controllable to a low value and coping with a low mu road is practicable.

Title: Magnetic recorder-reproducer
Inventor: TAKAMIYA TAKEHISA
IPC: G11B15/62
Filed: 1978-06-13
Abstract: PURPOSE: To obtain a sure and stable loading state with simple operation by moving tape engaging members through the use of two skew turning bodies.  
     CONSTITUTION: When the first, second skew turning bodies 11, 12 are turned while a tape 15 is in the state shown by the alternate dot and dash line, small gears 20, 23 rotate in the mutually differing directions of clockwise and counterclockwise and therefore the turning bodies 11, 12 turn in the directions respectively opposite from the above. Since this causes a shift pin 5 to move backward in the position shown by the solid line and tape engaging members 16, 17 to rise and turn toward the position shown by the solid line, the members 16, 17 engage to the tape 15 during the course of this movement. These are then so moved as to coil the tape to the first, second capstans 6, 7. When the turning bodies 11, 12 end turning, the  members 16, 21, pin 5, tape 15 are held in the position shown by the solid lines and the tape 15 coil on the capstans 6, 7 close at 150°, thus making contact to the front faces of the heads 1, 2. Thereby, the tape is surely and stably loaded.

Title: Sample introducing device for chromatograph
Inventor: WADA NAOKI
IPC: B01D15/08
Filed: 1988-03-26
Abstract: PURPOSE:To enable the injection of a slight amt. of a sample with good reproducibility by providing a small hole which communicates with the sample introducing part of a chromatograph to the wall of a sample injector and impressing voltage pulses between an apertured electrode disposed to face the small hole and the sample. CONSTITUTION:The sample introducing part 1 is heated by a heater 2 enclosing said part and a carrier gas flows from a supply pipe 4 through the introducing part 1 into a column 3. The front end of a sample injecting container 5 is projected into the introducing part 1 and the microhole 6 is bored to the tip thereof. An electrode 7 is provided on the inside surface of the container 5 and the apertured electrode 9 is provided in the introducing part 1. The sample soln. is prevented by the pressure of the carrier gas and the surface tension of the sample soln. from going out into the introducing part 1 when the sample soln. is injected into the container 5 at this time, but the sample soln. is attracted by the electric field of a high voltage and is accelerated and ejected from the hole 6 toward the electrode 9 when said high voltage is impressed between the electrodes 7 and 9 by closing a switch 10. The micrliquid drops are, therefore, ejected if the impulsive voltage is impressed to the electrodes. The size of the liquid drops is determined by the diameter of the hole 6 and the voltage and width of the pulses. The liquid drops are thus ejected with the good reproducibility.

Title: Hot wall epitaxial growth device
Inventor: EBE KOJI
IPC: H01L21/203
Filed: 1987-03-26
Abstract: PURPOSE:To prevent the ununiformity of composition of epitaxial growth layers by preparing hot walls at a lower part of a rotation path of a substrate by plugging an opening of the other hot wall with a flat-plate like member when epitaxial growths are performed with source materials of the prescribed hot walls at the substrate. CONSTITUTION:A substrate installation stand 22 is formed by a rotating flat-plate like member and a plurality of crucible hot walls 29-31 are prepared to correspond to a lower part of a rotation path of a substrate 24 which is formed with the rotation of the substrate 24 placed at the substrate installation stand 22 and the hot walls have a structure where their opening that are not clogged by the substrate are clogged by the flat-plate like member. The substrate 24 is placed on the hot walls 29 and 30 by rotating and, moving alternately them and components of source materials 26 and 27 in the hot walls 29 and 30 are deposited on the substrate 24 to form epitaxial layers of PbEuTe on the substrate 24. Further, the substrate 24 is placed on the hot walls 29 and 31 by rotating and, moving alternately them and the epitaxial layers of PbTeSe are formed. Since upper parts of the hot walls are always covered by the substrate installation stand, the epitaxial layers where no components ununiformity develops are formed without having disturbance of a molecular flow direction which is generated by the evaporation of the source materials in the hot walls.

Abstract: PURPOSE:To prevent an abnormal discharge and to efficiently form a film on a metallic strip by applying an earth potential to a vacuum vessel and a vapor-deposition source, providing a bias power source to apply a negative potential with respect to the earth potential to the strip and carrying out vapor deposition. CONSTITUTION:A metallic strip 1 is housed in a vacuum vessel 4 from a feeding coil 2 to a winding coil 3. The vessel 4 is kept at <1X1/10<2>Torr. The strip 1 extending from the feeding coil 2 to the winding coil 3 is electrically insulated from the vessel 4. The cathode of a bias power source 16 is connected to the strip 1. A negative potential of about -50 to -1000V with respect to the earth potential is applied to the strip 1 in a vapor-deposition chamber 5, and about +500 to +2000V with respect to the strip 1 is applied on a pretreating electrode 18 in a pretreating chamber 7. Since the vessel 4, vapor-deposition source 4, etc., have the earth potential and only the strip 1 has a negative potential with respect to the earth potential, an abnormal discharge is not generated in the vapor-deposition chamber 5.

Title: Secondary alkaline zinc battery
Inventor: FURUKAWA SANEHIRO
IPC: H01M4/42
Filed: 1981-05-14
Abstract: PURPOSE:To improve the charge/discharge cycle of a secondary alkaline zinc battery, by using crystalline zinc oxide as the main active material of the cathode of the battery. CONSTITUTION:Hundred parts of crystalline zinc oxide powder and five parts of cadmium oxide are mixed well with each other. About five parts of polytetrafluoroethylene-dispersed liquid is added to the mixture. After that, these substances are diluted with water they are mingled and kneaded together. The kneaded material is rolled several times to make a zinc sheet of prescribed thickness. Such zinc sheets are tightly secured on both the sides of a cathode current collector plate 2, thereby providing a cathode 1. Since the crystalline zinc oxide is used as the main active material of the cathode 1, the generation of zincic acid ions which would be the main cause of the electrodeposition of dendritic or spongy zinc is suppressed to greatly improve the charge/discharge cycle of the secondary alkaline zinc battery.

Title: Speedometer
Inventor: KOBAYASHI KUNIHITO
IPC: G01C22/00
Filed: 1986-03-31
Abstract: PURPOSE:To obtain a speedometer of reduced error and of excellent practical use, by calculating displacement speed and distance by a stored speed constant and measured time for each full-stride. CONSTITUTION:When the standard full-stride length is assumed as P0 and time required for displacement of P0 as T0, P0 X T0 = constant according to the law of inverse proportion and consequently, the actual full-stride length P and time T required for the full-stride becomes P X T = constant and P = P0 X(T0/T). This equation is available for determination of unmeasureable P with T0/T basing upon the standard P0 and by this equation the full-stride length P can really be obtained. Time required T0 for displacing the full-stride length P0 can be calculated by displacing a known distance with a walking speed to be measured or mean speed for walking and measuring number of full-strides and time required for above.
