Abstract: PURPOSE:To obtain the optimum cutting quality regardless of the force applying a razor head to the face because a top plate and a blade element moves with respect to the guard of a blade stand. CONSTITUTION:A razor head 1 is equipped with a blade stand 2 and a top plate 3 and a guard 7 is attached to the blade stand 2 and blade elements 4, 5 are attached to the top plate 3. The top plate 3 is supported on the blade stand 2 in a revolvable manner by a notch part 18 and a projection 13 and held at a constant position by an elastic arm 10. The edges 4a, 5a of the blade elements 4, 5 are exposed in the vicinity of the shaving surface connecting the guide surfaces 15a, 16a on the top plate 3 and the guide surface 7a on the guard 7. The top plate 3 and the blade elements 4, 5 can be moved with respect to the guard 7 against the elastic force of the elastic arm 10.

Title: Semiconductor device manufacturing equipment
Inventor: TSURUTA HIROKI
IPC: H01L21/265
Filed: 1985-12-16
Abstract: PURPOSE:To equalize impurity concentration in the surface of a semiconductor substrate by constituting the titled equipment of a means measuring the quantity of charges charged onto the semiconductor substrate and a means controlling the quantity of secondary electrons. CONSTITUTION:When impurity ion beams 3 are implanted into a semiconductor substrate 1, positive charges pass through a clamper 7 and a disk 2 and are absorbed to the ground. When positive charges are charged onto the semiconductor substrate, currents flowing through the clamper 7 and the disk 2 are reduced. The variation in the currents is detected by a fine-current measuring machine 10, the change of the current value measured is fed back to a filament current regulator 9, and primary electrons 5 are adjusted while secondary electrons 6 are also regulated, thus irradiating the upper section of the semiconductor substrate 1 b charges having reverse characteristics cancelling charging. Accordingly, positive charges are not charged because there are charges having reverse characteristics cancelling charging on the semiconductor substrate 1. An impurity can be implanted uniformly into the surface.

Title: Method of manufacturing semiconductor chip
Inventor: ISHIKAWA TOSHIHIKO
IPC: H01L21/78
Filed: 1999-10-04
Abstract: PROBLEM TO BE SOLVED: To provide a method by which an extremely thin semiconductor chip can be manufactured, without causing chipping. SOLUTION: In a method for manufacturing a semiconductor chip, the thickness of a wafer carrying many chips formed on its front surface is first reduced to a prescribed value by grinding the rear surface of the wafer. Then broken layers made at the time of grinding the rear surface of the wafer, is removed by polishing or etching the rear surface. In addition, grooves having a prescribed depth are formed on the front surface of the wafer along streets formed between the chips. Thereafter, the wafer is divided into individual chips by cleaving the wafer along the grooves. Since the broken layers formed on the rear surface of the wafer are removed and the wafer is divided into the individual chips, by utilizing the cleavage of the wafer after the rear surface of the wafer is ground in this way, occurrence of chipping can be suppressed effectively.

Title: Duty ratio deterioration compensation circuit by ttl-ic
Inventor: ITO TATSUTOSHI
IPC: H03K5/04
Filed: 1990-10-23
Abstract: PURPOSE:To compensate an output with 50% duty ratio with respect to the fluctuation of a duty ratio of an input clock by applying negative feedback control to a buffer amplifier circuit. CONSTITUTION:An input clock signal 1 is inputted to a buffer amplifier 4 via an amplitude limiter 2 and a high pass filter 3, and the output of the buffer amplifier 4 is fed to the input of the buffer amplifier 4 via an inverter 5, an amplitude limiter 6 and a low pass filter 7. Then the output of the low pass filter 7 and the output of the high pass filter 3 are superimposed by using a superimposing clock signal 9, and since the output of the low pass filter 7 is decreased as the duty ratio of an output clock signal 8 being an input to the inverter 5 is increased because the output of the inverter 5 is a DC component and the output of the low pass filter 7 is decreased as the duty ratio of the output clock signal 8 is decreased and the duty ratio of the output clock signal 8 is converted to be 50%. Thus, the clock whose duty ratio is decreased is compensated to 50% duty ratio.

Title: Method for removing offensive odor
Inventor: HORIOKA TOMOHARU
IPC: B01D53/74
Filed: 1997-10-16
Abstract: PROBLEM TO BE SOLVED: To effectively remove the offensive odor of an offensive odor generation source or the offensive odor generating chamber by sucking offensive odor gas to a deodorizing device to execute deodorizing while keeping the pressure of in-adjacent chamber space to be higher than that of offensive odor generating chamber space. SOLUTION: Offensive odor gas is sucked to the deodorizing device so as to execute deodorizing while keeping the pressure of in-adjacent chamber space being adjacent to the offensive odor generating chamber to be higher than that of offensive odor generating chamber space. In-adjacent chamber space includes a chamber itself when an equipment corresponding to the offensive odor generating chamber exists in the same room without restricting the one divided as the chamber. For example, a sewage measuring tank chamber where a sewage measuring tank 3 is arranged is made to be the adjacent chamber, the pressure of space inside the sewage measuring tank chamber is kept to be higher than that of space inside the sewage measuring tank 3 and also the offensive odor gas of the sewage measuring tank 3 is sucked to the deodorizing device so as to execute deodorizing.  It is favorable that pressure in in- adjacent chamber space is higher than that of the offensive odor generating chamber by about 8-10 mm H2 O.

Title: Digital video tape recorder
Inventor: KOMORI NOBORU
IPC: G11B27/28
Filed: 1993-10-19
Abstract: PURPOSE:To continuously reproduce index images and to easily and rapidly retrieve recording images by recording the static images stored in a memory means for index in the margin region disposed at the front end of a video tape. CONSTITUTION:A sub-code detecting means 13 detects start signals for index recorded in the sub-code regions disposed at every one track of the tape 1. A control means 14 executes reproduction operation once by controlling a memory 15 for index, extracts the DC and low-frequency components of the image data in a memory 11 and stores these components in the memory 15. A video recording means 16 adds an error correction code to the image data of the memory 15 and records the data in the margin region at the top of the tape and continuously reproduces the data, thereby obtaining the index images. As a result, the erasing of the images does not arise and the contents of the image of the recording tape are easily and rapidly retrieved even if the power source of the IC memory is turned off.
