IPC: G01M11/00
Filed: 1991-01-23
Abstract: PURPOSE:To measure a deep aspheric surface without contacting the same in a short time by arranging a recorded hologram at a specific position, passing the light from a member to be inspected and a reference light able to interfere with the light through the hologram, and forming interference fringes at an observation surface. CONSTITUTION:Parallel luminous fluxes are allowed to pass through a half mirror 51 and a condensing lens 53 to be reflected on an aspheric surface 57 of an aspheric lens prototype 55 manufactured as designed. The reflecting light is moved backward to the mirror 51 and reflected towards a photosensitive material 59. On the other hand, as a reference light enters from above, the luminous flux reflected by the aspheric surface interferes with the reference light and the interference fringes are recorded to the photosensitive material 59 as a hologram 23. The interference fringes are formed on the observation surface by the reflecting light passing through the hologram 23 from the lens to be inspected and the reference light if the hologram 23 is placed at the recording surface and the aspheric lens to be inspected is placed at the position of the prototype 55. It is made clear how much the aspheric surface of the lens shifts from the design by observing the interference fringes.

Title: Semiconductor integrated circuit
Inventor: NAKABAYASHI YOSHIE
IPC: H03K19/088
Filed: 1989-04-05
Abstract: PURPOSE:To prevent an oscillated output waveform or glitch by connecting a base of a 3rd transistor(TR) to a GND terminal and a power terminal, connecting its emitter to the power terminal and turning on the 3rd TR only when a GND terminal of the chip starts falling toward a negative level. CONSTITUTION:When a base level of a TR 4 goes to an H level and the TR 4 is turned on, a 2nd TR 6 is turned on and a TR 5 and a 1st TR 7 are turned off. The 2nd TR 6 discharges an output load and its discharge current flows from a GND terminal 3 of the chip to external ground through a lead induct ance. When the discharge current decreases and the level of the GND terminal 3 of the chip starts falling to a negative level by the action of the lead induct ance, the base level of the 3rd TR 11 is decreased by the capacitive coupling action of a PN junction diode 12 and the TR 11 is turned on. Then a current flows from the power terminal 2 to the GND terminal 2 and the rate of decrease in the current flowing to the lead inductance is relaxed.
