Title: Television broadcast program reservation display device
Inventor: MORI YUKIO
IPC: G06F3/0482
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To improve the convenience of reserving a program by displaying a current time and a reserved program time zone on a program display column so as to discriminate and recognize programs and time zones to be reserved. SOLUTION: A current time display icon 1 and a reserved time zone display 2 of a displayed electronic program list are continuously displayed independently of scrolling a channel display column 52 and a program 53. Assuming that 'Fishing', a program name of the 115th channel, is reserved, the time zone of the program is displayed on the reserved time zone display 2. When the channel display column 52 is scrolled to try to reserve, e.g. the program name of 'Hot spring trip', it is recognized that the time zone is in duplicate with the program having been reserved by the reserved time zone display 2. In the case that a cursor is pointed out on the name 'Hot spring trip', a viewer compares both the programs and selects either of them to set the reserved program as the reserved program name is displayed. Thus the viewer simply and quickly reserves his most preferred program.

IPC: B21J13/02
Filed: 1983-02-25
Abstract: PURPOSE:To extend the life of a punch by dividing a punch holder and a punch body to avoid stress concentration in a corner part. CONSTITUTION:A forging punch 1 is so formed that the top surface of a punch holder 1d is made flush with the top surface of a body 1b in the state of fitting the body 1b into the central hole of the holder 1d.

Abstract: PURPOSE:To form beam spots a fluorescent substance screen in a small configuration without distortion and improve resolution by impressing voltage having a prescribed relationship upon a pair of electrodes forming a main lens and corrective electrodes. CONSTITUTION:A pair of electrode elements 41 and 42 or electrode elements 51 and 52, which are divided in the vicinity of a main lens in the tubular axial direction so as to be opposed to each other and upon which the same voltage is impressed, are used as at least one electrode among a pair of electrodes 40 and 50 forming the main lens. Corrective electrodes 21 and 22 are arranged between a pair of these electrode elements so as to surround the periphery of these opposing parts. Assuming that voltage impressed upon one electrode forming the main lens is Va and the voltage impressed upon the other electrode is Vb, in the case of Va<Vb, V>Va or Va>Vb, the voltage represented as V<Va is impressed upon these corrective electrodes 21 and 22. Thereby, beam spots on a fluorescent screen can be formed in a small configuration without distortion, so that resolution can be improved significantly.

Title: Cleaning method for semiconductor device
Inventor: NIWAYAMA NOBUO
IPC: H01L21/304
Filed: 1990-02-08
Abstract: PURPOSE:To decide the cleaning time which is necessary and sufficient by a method wherein a means to detect the quality of a cleaning liquid is installed inside a cleaning tank and the cleaning time is controlled by detecting that the quality of the cleaning liquid is returned to an initial state. CONSTITUTION:A resistivity detector 2b is installed near a cleaningliquid discharge port 1b inside a cleaning tank 1; the resistivity of pure water during a cleaning treatment is measured by using a resistivity meter main body 2a connected to the resistivity detector 2b. When a semiconductor wafer 4 is cleaned in this state, a chemical liquid which is adhered to the semiconductor wafer 4 is diffused into the pure water, and a resistivity value is once made small. As a cleaning process progresses, the resistivity value becomes large. When the value becomes nearly equal to the resistivity value of the pure water in an initial stage, this means that the semiconductor wafer 4 has been cleaned completely. At this time, the cleaning process is finished. Thereby, an object to be cleaned can be cleaned in the cleaning time which is necessary and sufficient; the quality of the object to be cleaned can be ensured without using a wasteful cleaning liquid.

Abstract: PURPOSE:To improve heat efficiency and to uniformize the temperature distribution of a mirror finished surface by providing a movable sheet-like body for covering a heating means provided on the back surface of an antenna mirror finished surface and a fixing means for pressing the heating means to the back surface of the antenna mirror finished surface. CONSTITUTION:A silicon rubber heater 16 and a heat insulating material (silicon sponge) 17 are laminated on the back surface of the antenna mirror finished surface 1, a spacer 18 is incorporated and a back cover 19 which is made easily bendable in one direction by putting a slit is fixed by a flat countersunk head screw 22. By closely adhering the silicon rubber heater 16 to the back surface of the antenna mirror finished surface 1 in such a manner, the heat efficiency is improved and a power amount required for melting snow can be less. Since the contact area of the silicon rubber heater 16 is also large, the temperature distribution of the antenna mirror finished surface 1 is uniformized and the degradation of mirror finished surface accuracy is reduced. Since the structure of just pressing the heater 16 by sheet metal is also simple, the inexpensive snow melting device with improved assemblability is obtained.
