Title: Erecting real image type mirror lens
Inventor: SAKUMA NOBUO
IPC: G02B27/18
Filed: 1980-06-16
Abstract: PURPOSE:To make a titled lens adaptable as an erecting real image type mirror lens helpful for miniaturization of copying machines by using a mirror lens of which the front face is a spherical face and the rear face is a specific elliptical reflection face aligned of one focus to the spherical center of said spherical face. CONSTITUTION:A mirror lens 11 consists of a medium of refractive index (n), and its front face which is an incident and exit face for rays is a spherical face of a radius (r) of curvature having a spherical center O. The rear face 13 which is a reflection surface for rays is a part of an ellipsoidal surface 15 of revolution having a focus F' on the spherical center O of the spherical face 12, and having its axis at an optical axis A. This face 15 is so constituted as to substantially satisfy the condition equation I. The luminous flux from the top of an object surface 16 enters the spherical center O from the incident face 12 and forms an inverted real image point on the face 13, where it is reflected and heads for the other focus F and falls onto the exit face 12, where it is reflected and forms an erecting real image point on the original object face 16. This results in that the imaging system of which the curvature of field with respect to the luminous flux near the main rays is substantially zero is obtained.

Title: Semiconductor integrated circuit
Inventor: HASHISHITA RIYUUICHI
IPC: H01L27/092
Filed: 1984-04-23
Abstract: PURPOSE:To make a through current uniform to prevent the malfunction due to noise or the like by making logical thresholds of individual inverters different from one another in plural inverter circuits consisting of C-MOS transistors Trs connected to the same power source. CONSTITUTION:Inverter circuits 1-4 consisting of P-channel PCHMOS transistors Trs QP1-QP4 and NCHMOSTrs QN1-QN4 are connected to power sources V1 and V2 together, and these circuits receive input signals from input terminals IN1-IN4 respectively and take out output signals from output terminals O1-O4 respectively. Logical thresholds VT1-VT4 of circuits 1-4 are so set that VT1>VT2>VT3>VT4 is true. When the output state of each inverter is changed, through currents I1-I4 from the power source V1 to the power source V2 do not have maximum values at the same time, and therefore, the sum of currents I1-I4 is made uniform and does not have a sharp peak value, and thus, variance of the power source potential and superposition of noise onto power supply lines are suppressed to prevent the malfunction.

Title: Radio type level gage signal transmitter for gas station
Inventor: MAESHIBA SOZABURO
IPC: G01F23/00
Filed: 1992-04-04
Abstract: PURPOSE:To enable receiving oil level signals from a plurality of underground tanks with a single receiver by determining radio transmitting timing from liquid level meters in each underground tank with the use of randum numbers in different randum number series for each emitter. CONSTITUTION:For each transmitter 3-1 to 3-n, different series of randum numbers generated from a randum number generator 12 are used. For example, if the intervals of 7 signals generated in the transmitter 3-1 are irregular, and even if the initial 7 signals generated from the transmitter 3-2 overlap with the former, the irregularity of the intervals does not coinside with that of the transmitter 3-1. Therefore, signals isolated from the signals of the other transmitter are surely received by a receiver 6. Thus, even if a plurality of transmission signals from a plurality of transmitters are sent simultaneously, the probability of overlapping all transmission signals is very small because the intervals of each transmission signal has irregularity so that the signals from each transmitter can be practically discriminated independently.
