Title: Optical head
Inventor: ARAI RYUICHIRO
IPC: G11B7/09
Filed: 1986-02-07
Abstract: PURPOSE:To decrease the deviation of the axial line of an objective lens with respect to the optical axis at the end of assembling by forming a fixed supporting member fitting face of a base to nearly the same height as an objective lens holding position of a moving barrel. CONSTITUTION:A fixed supporting member 2 is formed by an inner cylinder 2b and an outer cylinder 2c having a ceiling and the circumference of the ceiling of the outer cylinder 2c is fitted to the fitting face 1a of the base 1 by a bolt 4 via a shim 3. The root of a guide shaft lever 7 is fitted to the ceiling of the outer cylinder 2c. Since the height of the fitting face 1a is nearly the same as that of the objective lens 6, even when the objective lens 6 is tilted, the tilt is caused on a prolonged line of an optical axis A, the incident luminous flux is converged nearly with the permissible aberration of the objective lens 6 and a vignetting quantity is reduced remakably more than that of a conventional head. Thus, the aberration of the objective lens 6 is decreased almost without a complicated correction and the reduction in the light intensity is prevented.

Abstract: PURPOSE:To remove the uneasiness of a driver even if the moving characteristic of a vehicle has suddenly changed by providing a detecting means for a front wheel steering angle and a means of notifying that said front wheel steering angle gets larger than the maximum value of a rear wheel steering angle, and securely informing said driver that the front wheel steering angle has exceeded the maximum value of the rear wheel steering angle. CONSTITUTION:A front wheel steering angle sensor 24 detects the steering angle of a front wheel and a warning device 44 notifies that the front wheel steering angle gets larger than the maximum value of a rear wheel steering angle. Accordingly, a driver can be securely informed that the front wheel steering angle has exceeded the maximum value of the rear wheel steering angle, enabling him to foreknow the point at which it becomes impossible to carry out a crab traveling when the steering of the front wheel is kept continued. Thereby, even if the moving characteristic of a vehicle has suddenly changed, the driver can accurately cope with the condition without becoming uneasy.

Title: Thin-film transistor array substrate
Inventor: UNO MITSUHIRO
IPC: G02F1/136
Filed: 1989-02-03
Abstract: PURPOSE:To improve the brightness of the picture of a TFTLCD by making the direction of the flow of the main component of currents made to flow from a source electrode to a drain electrode differ from both directions of a column and a row on which a gate wiring and a source wiring are extended. CONSTITUTION:The crossing angle theta of the direction of the flow of the main component of drain currents and the direction of a line on which a gate wiring 10 is extended is set within a constant range (0 deg.<theta<90 deg.). The smaller angle of the crossing angles of the direction of the flow of the main component of drain currents and the line direction is used as the angle theta at that time. Consequently, the occupying area of a source electrode 12 is reduced, the occupying area (shown broken lines) of a TFT (a thin-film transistor) is diminished, and the area of a picture element electrode can be increased only by the reduction of the occupying area of the TFT. Accordingly, the transmittance of a TFT array is augmented, and the brightness of the picture of a TFTLCD is enhanced.

Title: Camera system
Inventor: MORIYAMA KEIJI
IPC: G02B7/34
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To improve the performance of a photographing optical system while performing TTL system focus detection by branching a passing luminous flux from the front side of a lens shutter and detecting positional deviation between the image- formation surface of the branched luminous flux and a specified primary image- formation surface so that a focus may be detected. SOLUTION: An optical path branching means 3 branches the passing luminous flux from the front side of the lens shutter 4, and a focus detection means 5 detects the positional deviation between the image-formation surface of the branched luminous flux and the specified primary image-formation surface so that the focus of a 1st optical system 1a may be detected. Therefore, in the case of mainly using a 2nd optical system 1b for the purpose of the compensation of aberration, for example, the focus state of an entire photographing optical system is known from the focus state of the 1st optical system 1a. The focus is detected in a state where the lens shutter 4 is closed, so that a light shielding member need not be specially provided.  Furthermore, since the lens shutter 4 is arranged inside the photographing optical system, the compensation of aberration concerning off-axis light is performed by using the 2nd optical system 1b on a rear side, and vignetting caused in an obliquely incident luminous flux is effectively prevented.

Abstract: PURPOSE: To vary a fuel injection rate in every injection by arranging a controlling means which controls a motor generator means according to a fuel injection rate so as to change a rotational speed of a diesel engine and changing the rotational speed of the diesel engine so as to control the fuel injection rate. CONSTITUTION: As an action of a M/G system 30 can be electrically controlled, its response is quick. Therefore, output torque of a diesel engine 10 is finely controlled by controlling the M/G system 30. A rotational speed of a crank shaft 12 is controlled by means of the M/G system 30, and then, a rotational speed of a cam plate 20a is controlled. When a rotational speed of the cam plate 20a is changed, a reciprocating speed of a shaft 16a in a plunger mechanism 16 is changed. In this way, a fuel feeding quantity per a unit time from the plunger mechanism 16, in other words, a fuel injection rate is varied. A fuel injection quantity in every explosion and timing of fuel injection are controlled by controlling open/close of a spill valve 14.

Title: Electrodeless discharge lamp device
Inventor: SHINOMIYA MASAKI
IPC: H01J65/04
Filed: 1985-02-13
Abstract: PURPOSE:To lower the starting voltage even for long or wide lamp thus to lower the output of high frequency power source while to uniform the light emission by arranging more than two pairs of conductors in a container while connecting respective conductor pair in parallel. CONSTITUTION:Conductors 4a, 4b and 4b, 4c are paired respectively to connect two pairs of conductors 4a-4b, 4b-4c in parallel to the output terminal of high frequency oscillation circuit 2. Upon throw-in of power source 1, high frequency voltage is applied between the conductors 4a, 4b and 4b, 4c to discharge the gas in a container 3 thus to emit the light. Since an oval tubular container 3 is splitted into two, the distances between the conductors 4a-4b and 4b-4c are shortened to require low output voltage of the high frequency oscillation circuit 2. While the leakage of high frequency current is low because of short inter-conductor distance and the uniformity of light emission is high.

Abstract: PROBLEM TO BE SOLVED: To extend the utilization of outgoing the transmission bands by sending voice incoming signals by plural time slots for each terminal and sending outgoing voice signals with one time slot being the sum of plural time slots so as to minimize the number of time slots used for outgoing signals. SOLUTION: N-sets of outgoing time division multiplex access TDMA signal information from an exchange 11 are assigned dynamically depending on an idle state of the outgoing time slots, M-sets are extracted and some of the M-sets are added by a voice adder section 33 and the outgoing TDMA signals transferred to L-sets of signals less than the M-sets are sent to a TDMA equipment. An incoming time slot transfer section 32 transfers M-sets of time slots from the equipment 13 to N-sets of time slots of the exchange 11 and the resulting signals are sent. In this case, a relation of N>M>=L is established. Thus, the number of time slots used for the outgoing signals is minimized and excess outgoing time slots being a difference between the incoming and outgoing time slits are used for transmission of other media information so as to extend the utilization of the outgoing transmission bands.
