Abstract: PROBLEM TO BE SOLVED: To afford an unobstructed view for the opposite lane by providing a dihedral mirror in a designated condition in a designated portion near an obstacle obstructing the field of view such as a post of a high-level traffic equipment between the traffic lanes. SOLUTION: In the case where a vehicle 6 in the opposite lane can not be confirmed from the running vehicle 5 side because a post or the like of a high-level road is an obstacle 4 to the field of view, plane mirrors 8-1-A, 8-2 are provided opposite to each other on the intersection 1 side of the obstacle 4. At this time, the mirror 8-1-A on the intersection 1 side is shifted to the opposite lane 3 side to dispose the reflecting surface opposite to the mirror 8-2, and the mirror 8-2 is put nearer to the running lane 2 than the mirror 8-1-A to direct the reflecting surface toward the vehicle 5 side, so that the light ray of the vehicle 6 is incident on the mirrors 8-1-A, 8-2 and reflected to reach the vehicle 2 turning to the right at the intersection 1.  Secondly, a convex mirror is used as the mirror 8-1-A at need to widen the visual range, or a clear color is applied to the frame of the mirror 8-1-A to clearly show the image of the opposite lane 3, or a marker showing of which direction the opposite mirror projects the traffic situation is provided. Thus, the vehicle in the opposite lane can be confirmed before reaching the intersection.

Title: Gas laser tube
Inventor: KARUBE NORIO
IPC: H01S3/041
Filed: 1983-06-02
Abstract: PURPOSE:To eliminate the generation of a thermal strain, and to prevent the damage of a laser tube effectively by forming double tube or triple tube glass tube structure and providing a thermal-strain buffer and removal means to at least one part of the wall of an innermost glass tube. CONSTITUTION:A large number of ring-shaped projections are formed to glass walls 9 and 10. The projections function as the buffer and removal of a thermal strain. The projections 11 are difficult to be damaged when their noses are smoothed and expanded circularly R. A function removing the strain is insufficient when R is very small, and it is preferable that R is larger than 2mm.. When R takes a sufficient large value, attention must be paid because the projections obstruct the flow of cooling water. Both the projections on the glass walls 9 and 10 are formed to the outsides of the walls, but the projections may be shaped to the inside only in the projections of the glass wall 10. The projections may be formed at one position, at least and double tube structure or triple tube structure may be used especially when they are shaped to at least the glass wall 9.

Title: Detection system of identified phase
Inventor: FUJITA HIROYUKI
IPC: H04L7/033
Filed: 1984-05-18
Abstract: PURPOSE:To secure the identified phase of data by delaying forcibly the phase to be identified when no coincidence is obtained from comparison between the basic identified phase and the phase to be identified and then having the optimum phase control through a PLL when coincidence is obtained between both phases. CONSTITUTION:The input data is identified by an identifier 1 with a basic CLK. A phase comparator 2 decides the gain or delay of the phase of an input signal compared with an output signal. While a mask signal of 5 bits, for example, is produced by a mask production block 3 based on the output data of the identifier 1. Thus a phase is produced with a delay of 2 bits compared with the identified phase of the identifier 1. Then the rise and fall differentiators 4 and 5 perform the rise and fall differentiations by the mask signal of the block 3. A phase coincidence detecting circuit 6 compares a rise differential pulse with CLKCs 2-4 respectively. When the coincidence is obtained, a pulse is delivered to set an FF7 and to reset the FF7 with a fall differential pulse.

Title: Original platen
Inventor: KURETANI ETSUROU
IPC: H04N1/00
Filed: 1991-04-30
Abstract: PURPOSE:To accomplish an accurate image formed state at the total area of an original including the edge part of the original and to prevent the blurring of a copied image at the leading edge part of the original which is obtained on a photosensitive body by making an end face on a side opposed to a scale for positioning the original on an original platen opaque. CONSTITUTION:The opaque part 1A is formed on the end face on the side opposed to the leading edge of the scale for positioning the original. The opaque part 1A is constituted by painting the end face in black or sticking a black seal or tape to the face opposed to the inner surface side of the original platen. Since the opaque part 1A exists at the end face on the side opposed to the leading edge of the scale for positioning the original on the original platen 1, in such a case, incident light is prevented from passing and a refractive phenomenon is not caused. Therefore, the incident light on the lens is light excepting the light from the edge part of the original platen 1.

Title: Geotherm exchanger
Inventor: KUROIWA KAZUO
IPC: F24J3/08
Filed: 1988-04-21
Abstract: PURPOSE:To obtain geotherm exchanger which can be easily used effectively at a deep underground layer and has high efficiency and high capability, by a construction wherein a liquefied gas is circulated with decompression in a forced heat intake pipe, is naturally circulated in a natural heat intake pipe, and is circulated with pressurization in a heat radiating pipe. CONSTITUTION:A first pipe 1-4, a natural heat intake pipe 5-7 or a liquid-receiving natural heat intake pipe 8 and a second pipe 9-11 are inserted in bored holes BH under the ground, and a liquefied gas is circulated in the pipes. The forced heat intake pipe 1-4 is used for taking in heat by power, and is in a heat-exchanging relationship with the natural heat intake pipe 5-7, 8 to constitute a forced circulating pipe system comprising a compressor. The forward and backward pipe 1-4 can reduce a frictional pressure loss, more as a pipe part thereof for circulation with decompression is greater in diameter and shorter. Therefore, when natural heat intake is carried out at an upper part by the natural heat intake pipe 5-7 and the liquid-receiving natural heat intake pipe 8, the power required can be saved, and a device can be made smaller. The second pipe 9-11 is a forward and backward pipe for heat radiation in the depth under the ground, and in many cases, the liquefied gas in the pipe is introduced as a high-temperature high pressure vapor. When the vapor is converted into a liquid through releasing the heat of condensation at a position near the surface of the ground, a weight balance of the liquid liquefied gas can be obtained, and circulation with pressurization can be performed easily.

Filed: 1991-04-30
Abstract: PURPOSE:To reduce or eliminate a manual adjustment by a reproducing operator performing automatically adjusting work of reproducing speed by changing time length of a silent part based on a difference between play time and stop time and automatically performing the speed adjustment. CONSTITUTION:Play time tP and stop time tS are detected by a play and stop detecting circuit 1 of a foot switch. Subsequently, a relation tD between the play time tP and the stop time tS is calculated with an expression of tD=tP-tS by a to calculating circuit 2. By using this relation tD, length  t of a silent part is calculated from an 8-step silent part conversion table of silent part length provided in a central control part. Then, the speed adjustment is automatically performed by using the length  t in a silent part changing circuit 3. Such a table is stored in the 8-step table that when the relation to is decreased, the value of the silent part length  t is increased.

Title: Bipolar prom cell
Inventor: KOYAMA KAZUMI
IPC: G11C17/06
Filed: 1981-06-29
Abstract: PURPOSE:To reduce the capacity of a memory cell and to increase the reading speed, by connecting a Schottky barrier diode between the base and the collector  of a bipolar transistor. CONSTITUTION:A memory cell consists of a bipolar transistor TRQ and a Schottky barrier diode SBD connected between the base and the collector of the TRQ. The base-emitter area is opened before the writing is carried out and then short-circuited after the writing action. The forward voltage of a diode SBD is usually lower than the forward voltage of a junction diode Q. Thus the current flows almost through the diode SBD when such memory cell is selected and read out. As a result, no current flows to the diode Q although a large current is flowed to the memory cell. Accordingly the dispersed capacity is small and can be ignored. As a result, the load of a word line can be reduced and the reading action is accelerated.
