Title: Interpolation system for coordinate reading apparatus
Inventor: SAITOU YASUHIRO
IPC: G06F3/0488
Filed: 1979-01-19
Abstract: PURPOSE: To conduct simply and at a high speed the arithmetic opertion of interpolation distance data in an electromagnetic induction type coordinate reading apparatus, by detecting a maximum induction voltage level and induction voltage levels of sense lines at both sides of the sense line in which the maximum induction voltage level occurs, and then conducting required arithemetic operation.  
     CONSTITUTION: Interpolation distance data ΔX can be determined with reference to the ratio of (V p -V p-1 ) to (V p -V p+1 ) on the basis of a detection voltage V p  obtained from a sense line X i  and detection voltages V p-1 , V p+1  obtained from sense lines X i-1 , X i+1  at both sides of the sense line X i . Namely, a voltage ratio Q defined by a formula I is a primary function of ΔX and can be expressed by a formula II. Accordingly, a function table for the formula II should be prepared. Then, V p , V p-1 , V p+1  are detected, and the voltage ratio Q in the formula I is calculated. The data ΔX can be calculated in accordance with the formula II using the voltage ratio Q. Thus, interpolation distance data can be obtained at a high speed by a simple operation including only one division.

Title: Pickup system
Inventor: WADA TOMOYUKI
IPC: H04M3/42
Filed: 1986-01-14
Abstract: PURPOSE:To dramatically improve operability by previously registering an extension in a pickup group as a one for pickup and responding an incoming call at the time of a call incoming to another extension in the pickup group only by the registered extension's picking up a handset. CONSTITUTION:If any extension (a) belonging to the pickup group G1 executes the preset operation, a registration means 200 registers P the extension (a) as a pickup one. When a call arrives on any extension (z) in the pickup group G1 in that state, the extension (a) registered by the registration means 200 picks up a handset. Then a response means 300 causes the extension (a) to respond to a call incoming on the extension (z). Accordingly the extension (a) only picks up a handset in order to respond to the call incoming on any extensions (z) in the same pickup group G1, thereby dramatically improve operability.

Inventor: MANABE TOMOTAKA
IPC: G01J5/08
Filed: 1986-01-14
Abstract: PURPOSE:To enable stable temperature measurement, by focusing using a plurality of mirror surfaces containing at least one concave mirror in an optical system to meet changes in the atmosphere in a furnace such as variation in the refractive index of a medium. CONSTITUTION:A flat mirror 1 and a concave mirror 2 are arranged as radiation light focusing means in an HIP unit. An incident light is led to a concave mirror 2 by changing the direction thereof with the flat mirror 1 to be focused to a light receiving section 3. This requires only the use of a mirror surface without using a lens or the like designed for use in air at a normal temperature and pressure thereby making the HIP unit free from the effect of a medium gas refractive index. Thus, the optical system is adjusted even for changes in the medium gas refractive index thereby enabling stable temperature measurement.

Title: Zoom lens
Inventor: TAI MASAKUNI
IPC: G02B15/14
Filed: 1996-01-18
Abstract: PROBLEM TO BE SOLVED: To obtain the zoom lens of a double telephoto type where the matching of a lower ray and a diaphragm is excellent by satisfying a specified condition at least in a telephoto state in the zoom lens of the double telephoto type constituted of a positive first group, a negative second group, the diaphragm, a positive third group and a negative fourth group in order from an object side. SOLUTION: The zoom lens of the double telephoto type is constituted of the positive first group Gr1, the negative second group Gr2, the diaphragm S2, the positive third group Gr3 and the negative fourth group Gr4 in order from the object side. It is made to satisfy the inequality of 0.3<t/ΣD3<0.8: (t) is an axial surface interval from the diaphragm to the surface of the third group Gr3 being the closest to the object side and ΣD3 is the axial surface interval from the dxaphragm to the surface of the thard group Gr3 being the closest to an image side in the inequality. When it exceeds the lower limit of the inequality, the lower ray of an outermost shaft is omitted in the case of a small diaphragm. On the other hand, though it has an advantage with respect to the lower ray when it exceeds the upper limit of the inequality, a lens whole system is not made compact.
