Title: Rear wheel steering device for four-wheel drive type vehicle
Inventor: KOIKE SHIN
IPC: B62D5/04
Filed: 1987-08-28
Abstract: PURPOSE:To heighten the transmission efficiency of the steering force, which is transmitted from an actuator to the right and left rear wheels, by putting the axis or rotation of a driven gear within an acute angle formed by the axis of rotation of a driving gear and the direction of the tooth-trace of both driving and driven gears. CONSTITUTION:A ball nut 41 is threadedly engaged with the outer periphery of a relay rod 23 via a ball. The ball nut 41 is supported by a housing 24 via bearings 42a and 42b in such a manner that the nut 41 can rotate but it is not allowed to move in the axial direction. A driven gear 46 is fixed on the outer periphery of the ball nut 41 by means of a screw. Twist angle beta1, which is formed by the axis of rotation L1 of a driving gear 36 and the direction L3 of the tooth trace of both driven gears 36 and 46, is set at an angle of about 80 deg. to 85 deg., which is larger than the friction angle of this gear mechanism. In addition, the axis of rotation L2 of the driven gear 46 is situated within the acute angle formed by both axes L1 and L3. For example, twist angle beta2 is set at an angle of 0 deg. to 75 deg., while shaft angle beta3 at about 10 deg..

IPC: G03C1/498
Filed: 1985-09-28
Abstract: PURPOSE:To obtain a heat developable photosensitive material having high sensitivity and small thermal fogging by incorporating a core/shell type photosensitive silver halide particles in which the silver iodide content in the front layer of the photosensitive silver halide particles having 4-4mol% silver iodide content is loser than the silver iodide content in the inside layer into said material. CONSTITUTION:The silver iodide content of the photosensitive silver halide particles is 4-40mol%, more preferably 4-20mol%. The thermal fogging is little but the photographic sensitivity is low if the silver iodide content is <4mol%. The thermal fogging increases if the content exceeds 40mol%. The photosensitive silver halide particles are the core/shell type photosensitive silver halide particles in which the silver iodide content in the front layer of the particles is lower than the silver iodide content in the inside layer. The preferable silver halide component includes silver iodobromide and silver chlorobromide. The heat developable photosensitive material having the high sensitivity and small thermal fogging is thus obtd.

Title: Laminated branching filter
Inventor: TADAI HIROYUKI
IPC: H03H7/46
Filed: 1997-08-11
Abstract: PROBLEM TO BE SOLVED: To obtain a satisfactory branching characteristic by making the line width of a pattern electrode forming an inductance component allowing a signal on a high frequency side to pass higher than the line width of a pattern electrode forming an inductance component allowing a signal on a low frequency side to pass among two frequencies to be branched. SOLUTION: At the time of allowing a first frequency to pass a circuit on an L1 side and allowing a second frequency to pass a circuit on an L2 side, the line electrode constituting inductance L2 allowing the frequency on the high frequency side to pass is made thicker than the line electrode constituting inductance L1 allowing the frequency on the low frequency side to pass. The inductance of L2 of a notch circuit cutting the low frequency side with the low frequency side being 824 to 894 MHz (band width 70 MHz)and the high frequency side being 1850 to 1990 MHz (band width 140 MHz) to pass the high frequency side is designated to be small to increase its line width. Cutting on the low frequency side of a comparatively narrow band is made possible to reduce a passing and inserting loss on the high frequency side.

Title: Wiper control device for car
Inventor: TAKAHASHI SHINICHIROU
IPC: H02P3/12
Filed: 1982-12-09
Abstract: PURPOSE:To properly wipe a car window by operating a wiper when the time of pressing a switch is long and not operating the wiper when said time is short in the captioned device where a cleaning solution is injected in front of the when window the washer switch is pressed. CONSTITUTION:When a washer switch 7 is pressed for a relatively short period of time, a washer motor 8 is turned, and washing liquid is injected onto the front glass surface. Further, although a condenser C3 is then charged via resistance R6, the C3 is not sufficiently charged because of short time of pressing the switch 7, so that a wiper motor 3 is not driven with transistors Tr4, Tr3 in a non-conductive state. On the other hand, when the time of pressing the switch 7 is long, C4, C3 are sufficiently charged, allowing Tr4 to be turned on. Hereby, Tr3 is also turned on to permit a current to be conducted through relay winding 9, so that a relay contact point 10 is changed over to the normally-open (a) contact point side, and the wiper motor 3 is started, allowing the operation of the wiper 4 to be started.

Title: Method for detecting internal resistance of semiconductor chip
Inventor: SUGITA MASAKAZU
IPC: G01R31/26
Filed: 1999-07-30
Abstract: PROBLEM TO BE SOLVED: To detect internal resistance with high accuracy while excluding the contact resistance of a probe by applying a current to a bonding pad from a first probe and measuring the voltage through a second probe not touching the first probe. SOLUTION: A first probe 3 connected with a constant current circuit 4 is brought into contact with one of two bonding pads 2 of a semiconductor chip 1 and applied with a constant current. Under that state, a second probe 6 connected with a voltmeter 5 is brought into contact with the bonding pads 2 applied with a current without touching the first probe 3 in order to measure the voltage. Consequently, a current can be prevented from flowing through the second probe 6 and the first and second probe 3, 6 touching the bonding pads 2 can be prevented from imposing a resistance to the voltmeter 5. Since the contact resistance of the probe is excluded, the voltage V can be detected as the product of current I and internal resistance R with high accuracy.

Title: Memory device
Inventor: SATO TAKASHI
IPC: H01L27/12
Filed: 1988-08-31
Abstract: PURPOSE:Not only to enable a memory device of this design to execute reading operation at high speed with a low voltage drive but also to improve it in radiation resistance by a method wherein the thickness of a semiconductor region is made smaller than that of the depletion layer of the semiconductor region. CONSTITUTION:When electrons are taken into a floating gate 9, Vth is made to increase and a current is liable to flow between a source region 6 and a drain region 4, and on the other hand, when electrons are discharged from the floating gate 9, Vth returns to a starting voltage and a current becomes hard to flow. The presence of data is memorized depending on the change of Vth, and as electrons are taken into or discharged through a first insulating layer 8, a high voltage is usually needed. The thickness t of a semiconductor region 3 is made smaller than that of a depletion layer of a semiconductor material which forms the semiconductor region 3, whereby the shift value of Vth becomes larger when the same voltage is used and the voltage required for obtaining the same shift value of Vth can be decreased, so that a memory device of this design can be driven with a low voltage.

Title: Recorder
Inventor: OKAMOTO HIDEAKI
IPC: G06K15/10
Filed: 1988-08-31
Abstract: PURPOSE:To obtain a gradation printing with proper density independently of a recording medium and a gradation method by a method wherein a density of multivalued image data is corrected according to the comparison of real density data outputted from a density reading means with logical density data. CONSTITUTION:A carriage 21 is moved to a home position HP by driving a motor 24, thereafter being moved rightward with the recording of test patterns on recording paper P and traveled to the home position HP. After that, a read sensor 10a reads the densities of the recorded test patterns concurrently with the travel of the carriage 21, and the carriage 21 is moved to the home position HP. An arithmetic part 14 calculates data for converting a logical density so that the logical density of the test patterns is proportional to the read real density. The obtained correction table data is stored in a density conversion part 5, and the processing is brought to an end. Therefore, a density of input multivalued image data can be corrected so that a gradation density to be printed can be always proportional to the logical density. Thus, independently of the material of a recording medium and a gradation processing method, a gradation printing with proper density can be always obtained.
