Title: Product to be welded having decorative pattern welded thereto and preparation thereof
Inventor: KAWACHI HIDEO
IPC: B29C65/04
Filed: 1989-04-28
Abstract: PURPOSE:To reduce the labor in high frequency welding processing by superposing a transparent or translucent welding material containing fluorescent material on an article to be welded having a white or light-colored surface and welding the same to the article to be welded using a preformed welding surface having the surface corresponding to a pattern to be formed. CONSTITUTION:A welding part 3 preliminarily cut along the outer peripheral contour of an one-point pattern is received in and placed on a lower electrode 2 in matching relation to the inner peripheral side surface thereof. After the welding part 3 is placed, in article to be welded 4 is placed. An upper electrode 1 is placed on the welding part 3 and a current is supplied between both electrodes to perform high frequency welding. Whereupon, the thermal welding parts 3d, 3e of the welding part 3 brought into contact with a peripheral welding surface 2a and a central welding surface 2c are subjected to high frequency welding and the non-welding part 3f being the part other than said welding parts is not brought into contact with the lower electrode 2 because it is received in the non-welding part 2d of said electrode 2 and not subjected to high frequency welding. In the compressed thermal welding parts 3d, 3e, the density of the fluorescent pigment contained in a polyvinyl chloride film per a unit volume becomes high as compared with the uncompressed non-welding part 3f. The thermal welding parts 3d, 3e develop a color different from that of the non-welding part 3f.

A silver film is formed on the inner surfaces of the slits 2 and 3. The slits 2 and 3 form light guides from an outer surface S2 to the light receiving surface S1. The light guides are the curved paths caused by the inclination of the slits 2 and 3. An ultraviolet region is removed from light, which is inputted to the light receiving surface S1. Meanwhile, in the phototransistor 1, the limit wavelength is set at the upper limit or in the vicinity of a visible light region. Thus sensitivity to an infrared region can be suppressed to a low value.

Title: Semiconductor device
Inventor: YOSHIMOTO MASAHIKO
IPC: G06T1/00
Filed: 1986-05-14
Abstract: PURPOSE:To test a digital delaying means independently by incorporating a coincidence discriminating means in a semiconductor device in which a picture signal processing circuit a digital delaying means of (n) line is incorporated. CONSTITUTION:When picture signals of the same content are inputted to an input terminal 2 repeatedly every one line, after lapse of period of two lines from the start of inputting, the input picture signals perfectly coincide with two-line delay signals if operation of a two-line memory 3 is normal, and accordingly, signals of L level are outputted from a coincidence circuit 6. Conversely, when the input picture signals and two-line delay signals are discordant even 1 bit, H level is outputted from the coincidence circuit 6. Accordingly, normality of the two-line memory 3 can be tested by output signal of the coincidence circuit 6.

Title: Digital signal transmission line
Inventor: TAHASHI ICHIRO
IPC: H04L25/02
Filed: 1995-05-10
Abstract: PURPOSE: To reduce the noise effects when the digital signals are transmitted within an integrated circuit. CONSTITUTION: The clock signal CLK (the digital signal to be transmitted) which is outputted from a buffer circuit 1 is transmitted via a conductor pattern 8. Then a signal the inverse of CLK is transmitted via a conductor pattern 9. A differential amplifier 7 reproduces the signal CLK based on the result of voltage comparison obtained between both patterns 8 and 9 which are placed close to each other. Therefore, if a noise occurs on the digital signal of the pattern 8, the noise having a similar waveform to the noise of the pattern 8 occurs also on the pattern 9. In other words, the difference has substantially no variance between both patterns 8 and 9 even if the levels of these patterns vary by the noises. As a result, the noise effects can be eliminated for the output of the amplifier 7.
