Title: Position detecting apparatus running unit
Inventor: SASAHARA TOSHIHIKO
IPC: G01C15/06
Filed: 1983-11-10
Abstract: PURPOSE:To enlarge a detection range while performing the detection of a distance with high accuracy, by providing a sonic wave generator and a calibrating receiver spaced apart from said sonic wave generator over a constant distance to compare the sonic wave transmitting time between primary and secondary machines with that to the calibrating receiver. CONSTITUTION:The sonic wave transmitting time from the sonic wave generator 11 and the calibrating receiver 12 of a primary machine 1 is compared with that to the sonic wave receiver 19 of a secondary machine 2 to enable the measurement of the opposed distance between the primary machine 1 and the secondary machine 2 under an arbitrary atmospheric condition without receiving influence of a temp. or air density. In the next time, when the sonic wave generator 11 is exactly opposed to the sonic wave receiver 19, sensitivity becomes highest. Hereupon, both turntables 4, 14 are rotated and a rotary angle highest in sensitivity is read by a potentiometer 18 and the distance detection range of the secondary machine 2 can be enlarged by a sonic wave receiving signal at the time of this rotary angle.

Abstract: PROBLEM TO BE SOLVED: To provide a wheel type travel mechanism, safe and moreover easy and sure in operation, switching travel always safely even a construction machine is placed in a tilted ground, and eliminating the possibility of the runaway of the construction machine. SOLUTION: The connection between a planet carrier 25 and a ring gear 26 is released by a clutch 31 when an asphalt finisher carries out pavement to brake the rotation of the gear 26 by a brake 27, thereby reducing the speed of the rotation output of a traveling hydraulic motor 11 to a specified ratio. At the time of usual traveling, the carrier 25 and the gear 26 are connected by the clutch 31, and the rotation braking of the gear 26 by the brake 27 is released, thereby transmitting the rotation output of the motor 11 at a reduction gear ratio of 1. At the time of stopping, the clutch 31 connects the carrier 25 and the gear 26 to brake the rotation of the gear 26 by the brake 27, thereby transmitting the braking force of the brake 27 to respective parts to stop the rotation of the rear wheel.

Title: Toner and image forming device using this toner
Inventor: ICHIKAWA KAZUHIRO
IPC: G03G9/087
Filed: 1998-07-27
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of offset and suppress the liberation of an external additive from toner base grain to extend the service life and to prevent the adhesion of a transfer material to a fixing device. SOLUTION: Toner T is constituted so that the inclination (grain size of external additive/grain size of base grain) θ of an approximate straight line αobtained by approximating the distribution of grain size of an external additive (SiO2) to the grain size of base grain (C) by minimum square method is 0.4 or less. Accordingly, the grain size to be adhered to the base grain having high viscosity to a fixing device, including the primary grain size and secondary grain size of the external additive having low viscosity, is increased. Since the mutually adhering adhesive forces of a transfer material and the fixing device are thus minimized the offset of toner to the fixing device can be suppressed to reduce the adhesion of the transfer material to the fixing device.

Title: Power supplying structure for electronic device
Inventor: MIYAMOTO MITSUO
IPC: G06F1/18
Filed: 1986-09-10
Abstract: PURPOSE:To make voltage differences among power receiving sections equal to each other, by preventing voltage drops caused by differences in distance from a power supply device to the power receiving sections by using bus bars and, at the same time, setting the cross-sectional areas of the bus bars in such a way that the nearer to the power supply device, the smaller and, the farther from the device, the larger. CONSTITUTION:The power supply to a logic unit 3 mounted on a logical rack 1 is several hundreds ampere and the power is conducted to the unit 3 from the output terminal of a 0-V bus bar 6 through a 0-V bus plate 10b and frame 2 by means of power supply devices 4 and 5. The power supply to the logical unit 3 from the terminal of a returning -5 V bus bar 20 is made by means of longitudinal bus bars 23a and 23b brazed to a transversal bus bar 13 through L-type bus bars 12 and 16. Power supply from the power supply device 5 is made in the same manner. A potential difference is produced between points (a) and (b) of the transversal bus bar 13 and this potential difference is not supplied to the logic unit 3 as it is, but supplied by making the cross-sectional area of the longitudinal bus bar 23b smaller so that the voltage drops at points (c) and (d) can become the same. Therefore, power supply which is less in potential difference becomes possible to the logic unit 3.

Title: Phase type optical waveguide and its production

Title: Driving system of solid-state image pick-up element
Inventor: NAKAMURA MASAAKI
IPC: H04N5/335
Filed: 1983-11-11
Abstract: PURPOSE:To reduce power consumption of a reading line and noises by driving picture elements in such a way that picture elements arranged in the same line or row become a reading mode of plural lines or rows simultaneously due to a selective pulse to impress a selective line and an injection pulse to impress a reading line. CONSTITUTION:One longitudinal line is composed of six pieces of picture elements. When two-fold accumulation time TINT of a signal is taken for one frequency Tp, selective pulses are successively impressed from No.1 to No.6 picture element in a period of t1-t6. However, a selective pulse for No.1 picture element is impressed until time t3, and therefore signal reading time TR' is three times longer than conventional reading time TR. Each selective pulse overlaps each other and is impressed while the pulse is shifting. Such a system is adopted that reading time TR' is spread compared with the conventional one, and one frequency Tp' is magnified while accumulation time of a signal TINT is held in the required constant value; therefore a reading frequency can be delayed regardless of an increase in the number of picture elements. As a result, reduction in noises and power consumption becomes possible.

Title: Equivalent conversion method of explosion on two free surfaces in rod-shaped columnar charge to explosion on one free surface
Inventor: NAKAJIMA YASUJI
IPC: F42D1/00
Filed: 1997-07-22
Abstract: PROBLEM TO BE SOLVED: To provide the equivalent conversion method of an explosion on two free surfaces in a rod-shaped columnar charge to that on one free surface so that a safe explosion for preventing any errors can be executed even in the case of the explosion on two free surfaces in reference to the minimum resistance wire length, by establishing the definition of the minimum resistance wire length that can cope with both explosions on one and two free surfaces. SOLUTION: In a rod-shaped columnar charge to two free surfaces, a punching angle αand an angle β between both free surfaces are both equal, namely 90 deg., and the charge consists of a punching hole diameter (d) where a punching hole length M has a hole edge on a first free surface G1, a charge length N, and an insert length P. Therefore, when the minimum resistance wire length W (the minimum distance between the first free surface G1 and the upper edge of the load length N) and the insert P are set to mutually equal relationship (P=W), a second free surface interval length E (the distance between the punching hole length M and the second free surface G2) and a punching interval length D (the distance between the punching hole length M and an adjacent punching hole length) are converted to an explosion on one free surface in a relationship being equal to the minimum resistance wire length W (E=W=D).
