Filed: 1990-11-09
Abstract: PURPOSE:To increase safety and prevent damages of a rotor due to the friction heat by covering the outerside of an auxiliary agitator with a protective cover. CONSTITUTION:A main agitator 3 scrapes out dust on a floor to be cleaned, a carpet for instance, to take it into the suction inlet 1 of a nozzle body 2. The dust taken into the suction inlet 1 reaches the filter section by the suction force. When cleaning the corners of a room, an auxiliary agitator 10 is handled to guide along the corners of the room. Since the outside of the auxiliary agitator 10 is covered with a protective cover 15, there is almost no fear that children touch the agitator members of the auxiliary agitator 10 even if their hands approach to the agitator by mistake. A part of dust scraped up by the auxiliary agitator 10 is entrapped between the auxiliary agitator 10 and the protective cover 15. But since a dust-removing hole 16 is formed on the protective cover 15, the dust is discharged from this dust-removing hole 16 to the outside.

Title: Manufacture of semiconductor device
Inventor: KAKIUCHI KOJI
IPC: H01L21/336
Filed: 1987-12-01
Abstract: PURPOSE:To perform annealing at high temperature in a short time and to suppress a short channel effect, by using rapid thermal annealing(RTA), and projecting light from a halogen lamp on a substrate, in manufacturing a MOSFET. CONSTITUTION:When the source and drain of an NMOS are formed by double diffusion and annealing steps of two times are performed by RTA (1,000 deg.C, 10 seconds), a short channel effect is decreased to a large extent by performing the RTA definitely. In lamp annealing, the distance of impurity diffusion becomes long in the annealing at high temperature for a long time. Therefore it is not advantageous for the short channel effect. It is therefore desirable to use more gentler conditions as much as possible. A MOS transistor is normally operating at 1,100 deg.C for 10 seconds. This annealing condition supports one upper limit.

Filed: 1986-12-22
Abstract: PURPOSE:To prevent a kick back pressure from being exerted on a master cylinder, by a method wherein a control valve, opened and closed by means of a drive means, is situated between an input oil pressure chamber and a master cylinder, and the drive means reduces the opening of the control valve to a low value or zero with the increase in an oil pressure in an oil pressure chamber communicated to a control chamber. CONSTITUTION:When a modulator 2 performs antilock operation to decrease the volume of an input oil pressure chamber 14, the opening of a control valve 52 is reduced to a low value or zero through a drive means 50 actuated according to an increase in an oil pressure in a control chamber 16, and an oil pressure in the input oil pressure chamber 14 is prevented from being exerted directly on a master cylinder. Besides, although an oil pressure between the input oil pressure chamber 14 and the control valve 52 is increased through the motion of the control valve 52, an oil pressure increased through actuation of an accumulator 53 is accumulated. Thus, an adverse influence is prevented from being exercised on antilock control work effected by means of a modulator 2. Besides, during normal brake, a brake oil pressure from the master cylinder M is fed to the input oil pressure chamber 14 according to the opening of the control valve 52.

Title: Secondary high harmonic light generating element
Inventor: UNO TAKEHIKO
IPC: G02F1/37
Filed: 1987-12-04
Abstract: PURPOSE:To considerably improve the efficiency of conversion to secondary high harmonics even in case of the use of optical materials having a relatively low nonlinear effect by inputting the light to be converted to a multiplexer through a feedback path and multiplexing it with an input light to feed back it to the incidence part of a nonlinear optical medium. CONSTITUTION:The incident light having a wavelength lambda0 is led to a nonlinear optical medium 1 through a multiplexer 3. A part of the incident light is converted to high harmonics having a wavelength lambda0/2 in the medium 1 by the nonlinear effect, and the other part is outputted from the emission end of the medium 1 with the same frequency as the incident light, namely, the same wavelength lambda0 as a fundamental wave. The emitted light from the medium 1 is made incident on a demultiplexer 2, and the high harmonic component is taken out to the outside as an output light 5, and the fundamental wave component is made incident on the multiplexer 3 through a feedback path 6. The multiplexer 3 multiplexes the incident light and the feedback light fed back through the feedback path and they are made incident on the medium 1 again. Since the fundamental wave component which is not converted to higher harmonics in the medium is returned to the input end of the medium 1 through the feedback path and contributes to conversion again in this manner, a high conversion efficiency is obtained.
