Title: Small-sized photographic lens
Inventor: FUJITA HISAO
IPC: G02B13/18
Filed: 1982-12-28
Abstract: PURPOSE:To obtain a small-sized photographic lens which is a wide-angle type, bright in its F-number and can correct an aberration satisfactorily by placing a front group and a rear group having a refractive power of positive and negative, reducing a telephone ratio, also, constituting the front group of a triplet type, and forming the rear group by a strongly curved meniscus lens. CONSTITUTION:A titled lens is formed from the first lens L1 of a positive meniscus lens whose convex surface is turned to an object, the second lens L2 of a biconcave lens, the third lens L3 of a biconvex lens, and the fourth lens L4 of a negative meniscus lens whose image side has an aspherical shape and whose object side has a strong concave surface, in order from an object side. In this state, when (f), d6, d4, N1 and N3, and DELTAX(0.7R8) denote a focal distane of the whole system, a space between the third lens and the fourth lens, a space between the second lens and the third lens, refractive indexes of the first lens and the third lens, and a value of DELTAX in case of phi=0.7¦R8¦, respectively, the conditions of the inequalities are satisfied. In this way, a deterioration of the aberration is prevented by constituting the front group of a triplet type of positive, negative and positive lenses. Also, a wide angle retrofocus type is placed in reverse by forming the negative lens of the rear group by a negative meniscus lens, and the abberation can be corrected satisfactorily up to a wide view angle.

Abstract: PURPOSE:To reduce the retrieval time of an information buffer by providing an information buffer queue for each terminal equipment corresponding to a terminal number into an information buffer so as to constitute queues duplicatedly in both lateral and longitudinal directions in the terminal equipment in the same terminal number as the terminal number. CONSTITUTION:Information buffers 11-13 correspond to three terminal equipments of a subscriber A, information buffers 21-23 correspond to three terminal equipments of a subscriber B and information buffers 31, 32 correspond to two terminal equipments of a subscriber C. When a terminal equipment corresponding to the information buffer 31 is cut off, an exchange uses its terminal number as a key to retrieve a queue. Since the cut-off information is set corresponding to be cut-off of the terminal equipment corresponding to the information buffer 31, the information buffer 31 is discriminated to be an object of retrieval. An exchange removes the information buffer 31 from the chain so that each item of the succeeding subscriber of the information buffer 21 and the tail of the pointer 10 designate the address of an information buffer 32.

Title: Device for indication in vehicle
Inventor: HASEBE KOUJI
IPC: G09G3/00
Filed: 1982-12-27
Abstract: PURPOSE:To enable the indication of a hazard even if an ignition switch is off, by providing a hazard switch in parallel with the ignition switch to put a constant voltage generator into operation in response to the signal of the turn-on of either of the switches. CONSTITUTION:When an ignition switch 11 is turned off at the stoppage of a vehicle, a constant voltage vanishes from a constant voltage generator 23 so that an input processing circuit 50, an AD converter 60, a microcomputer 70 and a drive circuit 80 are put out of operation. As a result, an indicator 90 cannot perform indication. A hazard switch 12 is then turned on to generate the constant voltage again in response to the signal of the turn-on of the switch so that the microcomputer 70 resumes the execution of an indication control program. As a result, a hazard can be shown by the indicator 90 comprising liquid crystal display elements, a CRT and field-effect light emission elements or fluorescent display tubes. The hazard can thus be indicated even if the ignition switch 11 is off.

Title: Probe of probe card
Inventor: KIYAMA MAKOTO
IPC: G01R1/067
Filed: 1989-09-01
Abstract: PURPOSE:To evaluate electromagnetic characteristics of a semiconductor wafer with more microorder by providing a metallic wire that the tip of an electrode pad is made to contact and an insulator for reinforcement which reinforces the metallic wire. CONSTITUTION:This probe is provided with the metallic wire 6 whose tip is made contact with the electrode pad 5 of the semiconductor wafer and the insulator 7 for reinforcement which is provided surrounding the periphery of the metallic wire 6 and reinforces the metallic wire 6. The metallic wire 6 is reinforced by being surrounded with the reinforcing material 7 made of the electric insulator. Consequently, the metallic wire 6 is usable from a 2.5 mumphi wire diameter when its material is W. Therefore, when the in-plane distribution of the electric characteristics of the semiconductor wafer 2 is measured, fine probing becomes possible because the wire diameter of the metallic wire 6 is small. Consequently, the electric characteristics of the semiconductor wafer can be evaluated with more microorder.

Inventor: ABE HIROAKI
IPC: G02F1/29
Filed: 1992-08-04
Abstract: PURPOSE:To provide the waveguide type optical function device having many kinds of optical functions by one element. CONSTITUTION:Light transmits a glass substrate 31 and a transparent electrode 32 and a photoconductive layer 33 is irradiated with this light when the right half of the liquid crystal waveguide type element 30a is irradiated with the light. The resistance value Rexp of this part is then lowered as compared with the resistance value R of the part not irradiated with the light. The voltage impressed to the liquid crystal layer 35 of the photoirradiated part is, therefore, increased from the voltage impressed to the non-photoirradiated part. The liquid crystal molecules 35a of the liquid crystal layer 35 of the photoirradiated part are oriented perpendicularly to the layer direction and the liquid crystal molecules 35a in the unirradiated part are held oriented in the direction horizontal with the layer direction. The refractive index of the liquid crystal layer 35 in this part decreases and the equip. refractive index Nexp of the waveguide layer 37 of this part is made smaller than the equiv. refractive index N of the unirradiated part when the liquid crystal molecules 35a are oriented perpendicularly. Various kinds of the functions, such as polarization function, optical switching function and lens function, are obtd. by the parts where the refractive index is different.
