Title: Automatic/manual change-over control method for suspension hardness
Inventor: IWANO MAKI
IPC: B60G17/015
Filed: 1984-01-30
Abstract: PURPOSE:To improve the controllability by detecting the presence and the absence of any output of a signal used for controlling posture such as of roll nose type or the like with respect to suspension system and then performing manually changing over operation after a critical state, if any, is avoided. CONSTITUTION:When a shift switch 10 provided for automatically or manually performing hardness control of a vehicle's suspension is changed over from the auto-mode contact point to the manual-mode contact point, determination whether the vehicle's driving state is being placed under the posture control or not is made according to the provision of signals for a primary AND circuit 14 from both the switch 10 and an OR circuit 16. If the state is being placed under the posture control, a Q' output can be given from a flip-flop 20 and an output signal be given from a secondary circuit 22. A time delay quantity may be therefore discriminated in a circuit 22 till the completion of the posture control state. The signal from the circuit 22 is then sent to a third AND circuit 26 via a secondary inverter 24, and the circuit 26 makes certain that the switch 10 has been changed to the manual-mode contact. Thereafter, the circuit 26 generates a manually changing signal 28.

Filed: 1999-01-22
Abstract: PROBLEM TO BE SOLVED: To realize a semiconductor photo detecting element of high speed and efficiency which needs no external power source. SOLUTION: A doping dipole structure constituted of an N-type high density delta doped layer 132 and a P-type high density delta doped layer 131 which are adjacent to each other at most 20 nm is periodically formed in an undoped layer 133 which is to be irradiated with a light, thereby turning the band structure of a light absorbing layer into a sawtooth type.

Title: Magnetic recording medium and its production
Inventor: KAWAHARA SETSUKO
IPC: G11B5/842
Filed: 1990-01-24
Abstract: PURPOSE:To obtain high output and low noise by specifying the average major axial lengths l1, l2, and l3 of the magnetic powder of the first, second and third magnetic layers, respectively, and each film thickness H1, H2, H3 in specified ranges. CONSTITUTION:The magnetic powder in the third magnetic layer as an upper layer is specified to have l3 as small as 0.15 - 0.20mum shown in the formula I. Thereby, high density recording is possible, electromagnetic conversion characteristics, especially such as S/N and output in a high frequency range, are improved and good recording and reproducing of video luminance signals can be realized. Since l2 of the magnetic powder in the second layer as the intermediate layer is specified to 0.20 - 0.30mum, satisfactory recording/ reproducing of HiFi audio signals can be attained. It is required that H3 and H2 are made 0.05 - 0.30mum and 0.1 - 1.0mum, respectively. If each layer is made thinner than these ranges, the effect of each layer decreases, while with thicker films, the effect of the lower layer is prevented. The first magnetic layer provided under the second magnetic layer has l1 of 0.30 - 0.40 and thickness H1 1.0 - 3.0mum, which improves the output characteristics of video signals which are in a lower range than the luminance signals.

Abstract: PURPOSE:To reduce the influence of a rush current upon an AC load, by controlling the power supply mode of a heater in accordance with the time of turning- off of the heater in the temperature control of a copying machine or the like. CONSTITUTION:In a fixing device of a recorder such as a copying machine or the like, the temperature detection signal from a thermistor TH103 is inputted to a terminal A1 of a mcrocomputer muCM100 incorporating an ROM, an RAM, etc., and the muCM100 converts this signal digitally.

The muCM100 detects the turning-off time of the power supply of the heater 104 and performs such control that the power supply mode at the heater turning-on time is different in accordance with the turning-off time, and thus, the time of variance of the power source for the power supply to the heater is reduced.

Abstract: PROBLEM TO BE SOLVED: To simply and stably stand a retaining part member for retaining a wiring board on a pallet main body, without using a magnet, in a pallet which mounts a wiring board and conveys it in a reflow furnace. SOLUTION: Many holes 19 are formed in a plane part 17 of a pallet main body 13. A retaining part member 15 consists of an almost inverse V-shaped spring material wherein a pair of leg parts 23 are connected in the upper parts. In the lower end portions of both the leg parts 23, insertion parts 25 which can be inserted into the holes 19 are formed. On the insertion parts 25, stopper parts 27 which can not be inserted into the holes 19 are formed. The interval between the leg parts 23 is narrowed by an external force, and the insertion parts 25 are inserted into the holes 19. When the external force is removed, both the leg parts 23 are stretched by spring elasticity, and the lower end portions of the leg parts 23 engage with the edge of the hole 19. Thereby the state that the retaining part member 15 stands can be maintained.
