Abstract: PURPOSE:To quickly and easily position a projection lens and the first mirror by constituting the titled reader so that the projection lens and the first mirror can move integrally in the first direction in an orthogonal plane to an optical axis, and the projection lens can move by holding a relation to the first mirror in the second direction being different from the first direction in the orthogonal plane. CONSTITUTION:A lens holder 8 can move integrally and relatively in the X direction and the Y direction against a body substrate 10 by fixing it to a fitting plate 9 with two pieces of screws B1. On the other hand, a mirror holder 11 can be move by following the lens holder 8 only in the direction X against the movement of the lens holder 8. Accordingly, in case of positioning a projection lens 7 and the first mirror 12 against condenser lenses 4 and 5 of a light source part, the positioning can be completed by moving the lens holder 8, and thereafter, only fixing the mirror holder 8 with two pieces of screws B2.

Abstract: PURPOSE:To provide a balancing-weight mounting apparatus in which a clasp for a balancing weight is mounted on a lug part for a rim at a tire wheel without causing a problem such as a hammering operation. CONSTITUTION:A force-fitting means by which a clasp B1 for a balancing weight B is force-fitted while it is being deflected along the cross-sectional shape of a lug part R1 for a rim R is provided. As the force-fitting means, a force-fitting member 2 which has a contact face 21 which force-fits the clasp B1 so as to be deflected as mentioned above when the member is turned around a support shaft S1 is used suitably. The forcefitting means may be arranged on a moving head 1 which can be moved with reference to a tire wheel W. Two sets of moving heads 2 may be installed on both faces of the tire wheel W.

Title: Gravitation type heat pipe
Inventor: YAMASHITA KAZUO
IPC: F28D15/02
Filed: 1981-02-09
Abstract: PURPOSE:To improve transmission of heat by forming recesses in a heat receiving section of a heat pipe. CONSTITUTION:Bubbles 4 produced at a lower portion of work fluid rise upward along the upper surface of the pipe wall. However, since recesses B are formed in the pipe wall, the rising direction of the bubbles is changed by the recess B and carried toward the lower surface of the pipe wall. As the bubbles rise further upward, the above process is repeated. Since the bubbles are carried toward the lower surface of the pipe wall as described above, turbulence is produced in the work fluid, so that bubbles can be produced from the entire surface of the pipe wall. Thus, it is enabled to raise the efficiency of heat transfer irrespective of the setting angle of the heat pipe.

Title: Measuring plate and device for measuring wheel alignment
Inventor: UNO HIROSHI
IPC: G01B11/26
Filed: 1997-01-30
Abstract: PROBLEM TO BE SOLVED: To simplify the constitution of a device, to decrease the cost of manufacturing and to facilitate the control and the adjustment. SOLUTION: In a measuring plate 4, an optically uniform distance measuring region MLA is provided in the extending direction to the sides of the front and rear directions of a vehicle under inspection with respect to a measuring mark region MRK. Therefore, the distance to the measuring plate 4 can be accurately obtained without the effect on the measurement using the measuring mark region MRK by irradiating distance measuring light on the distance measuring region MLA. Thus, the accuracy of the measurement of wheel alignment can be improved. Furthermore, since the distance measuring region can be provided as the large area, outer distance measuring light emitting devices 6-1 and 6-2 for irradiating the distance measuring light can be used under the fixed state. The constitution of the device can be simplified without decreasing the measuring accuracy.  Furthermore, the irradiating positions of the distance measuring light beams of the distance measuring light emitting devices 6-1 and 6-2 can be largely separated, and the angle measuring accuracy of the measuring plate 4 based on the distance difference of both parts can be improved.

Abstract: PURPOSE:To perform dial origination at the time of a power failure by using divertedly a contact of a push-button dial which is used to input a data transmission signal in a conducting state for driving a selection signal generating circuit in case of the power failure. CONSTITUTION:If the power failure occurs, electric power supply to terminals DA and DB is cut off, so a relay 5 is turned off and contacts 5-1-5-4 are as shown by solid lines. In this case, the path of diodes 14-20 is formed and a group of lower contacts of the push-button dial 1 operates as a common contact. Transistors TR13 and TR12 are on and a TR11 is turned off to flow a current in the other of a terminal LA, coil 6, handset 7, TR13, and a terminal LB, allowing a telephone call. For example, when a push button 1 of the dial 1 is pressed in said state, contacts (a) and (a') are made to turn off the TRs 12 and 13 and turn on the TR11, and a current is supplied to the selection signal generating circuit 4 to operate the circuit 4. In this case, the data setting of a selection signal is performed by the contact (a).

Abstract: PURPOSE:To shorten the processing time easily and at low cost by executing readout/write of data from and to a memory by switching a bank. CONSTITUTION:In case when both data of 256 bytes in a bank0 11-1 and a bank1 11-2 are read and brought to OR, and transferred to a bank2 11-3, a CPU initializes a value N=25 to a counter.

Next, the data is read by sending out an address and a read signal 15 to the banks0,1, and OR processing is executed, and the processed data is written on the bank2 by an address and a write signal 16. A switching circuit 24 outputs the respective designated data of the latching circuits 21-23 to a decoding circuit 13 by sending out the signals 15, 16. The circuit 13 sends out a selecting signal, and designates the banks0-2 for executing read or write from the inside of a memory 11.

Abstract: PROBLEM TO BE SOLVED: To suppress the fluctuation of the beam diameter of a light beam and the fluctuation of the light quantity distribution without complicating the structure. SOLUTION: The direction of an LD 16 is adjusted so that the optical axis L<1> of the light beam may be slightly inclined to a side close to an fθ lens 14 as compared with the conventional optical axis L<0> , and in the case the reflection surface of a rotary polygon mirror 12 faces so that the incident light beam may be reflected to a side close to the optical path of the aforesaid light beam, the boundary of an irradiation range of the light beam shown by a dotted circular mark is positioned on the reflection surface of the rotary polygon mirror 12, and a part of the reflection surface along a main scanning direction is not irradiated with the light beam.  In the case the reflection surface faces so that the incident light beam may be reflected to the center in a deflection extent, or in the case the reflection surface faces so that the incident light beam may be reflected to a side opposite to the side close to the optical path of the incident light beam, the light beam is made incident on the whole range of the reflection surface along the main scanning direction, so that the width of the light beam emitted from the rotary polygon mirror is almost fixed.

Abstract: PURPOSE:To enhance the transmission efficiency by giving correction to the self- terminal clock signal so that the self-terminal clock signal may be in agreement with the center point between the synchronous signal transmission time and the reception time. CONSTITUTION:The 2nd terminal comprises transmission device 11, reception device 12, clock generation device 13, transmission timing control unit 14 and timing comparison device 15 respectively.
